Glue for working with roofing felt is a homogeneous adhesive mass, which is made using multi-component mixture technology. The basis for the manufacture of this adhesive is the following components:
- Bitumen;
- Solvent;
- Technical filler;
- Technological additives.
There are two types of mastic - the so-called hot and cold. From the name itself, it is obvious that the use of cold mastic is possible with short heating and mixing with a solvent, and hot mastic must be brought to required temperature, which on average should be about 200 degrees Celsius and such a mass takes much longer to cook.
The use of the described mastics is possible when waterproofing floors, walls, foundations and other elements of buildings and structures.
Advantages of using bitumen adhesive
The use of bitumen glue is rightfully considered the most reliable and in an efficient way installation of roofing felt waterproofing. The main advantage of using mastic over other methods of fastening roofing felt is the absence of air pockets when connecting joints of rolled material. Mastic allows you to achieve a solid monolithic waterproofing sheet that will serve for a long time without the risk of damaging the edges and joints of roofing felt sheets.
However, it should be noted that hot and cold mastic differ significantly in price range. Price of bitumen glue for roofing felt, which falls into the cold category, will be much higher since this type of mastic is ready to use and does not require long preparation.
How to glue roofing felt to cold or hot mastic?
Before how to glue roofing felt to cold or hot mastic, it is necessary to take care of cleanliness work surface. It is unacceptable to be present in the treated area construction waste, dust or other foreign objects.
It is also necessary to take care of personal protection When working with bitumen glue, use gloves, a respirator and safety glasses. If the upcoming work involves being indoors and not on outdoors, then it is necessary to take care of its effective ventilation.
Before gluing the roofing material to the working surface, it is necessary to prime it to increase the strength of the base and improve adhesion.
On average, mastic consumption should be 1.5 - 2 kg per square meter. m. This indicator depends on many factors, however, failure to comply with the norm can significantly affect the quality of work.
To apply bitumen adhesive, a notched trowel with a tooth size of 4 mm is usually used, and for hot mastic, the consistency of which is too liquid for a trowel, can be used special brushes, with the help of which the glue is evenly applied to the work surface.
You can buy cold mastic for roofing felt in any specialized stores. In this case, you should pay attention to the compliance with GOST of the mastic manufacturing technology, the integrity of the original packaging and the deadline for use. Average term The shelf life of bitumen adhesive is about 12 months, so when determining required quantity Care should be taken when calculating the required volume. Today there are varieties bitumen adhesives, which, thanks to unique technologies, can be used on wet surfaces or on surfaces with aggressive chemical environments.

Ruberoid is used for roofing works for a very long time and during this time has gained fame as the most reliable budget material. Roofing felt is based on roofing cardboard impregnated petroleum bitumen and covered with special crumbs. This material is successfully used for roofing work on commercial or industrial facilities.
For installation and repair of roofing felt coatings, it is necessary to use special mastics available on the market in the widest range. How to seal roofing felt on the roof will be discussed in this article.
Technology for laying roofing felt on the roof
Ruberoid is a rolled roofing material, for the production of which special cardboard with a density of 200-420 g/m2 and bitumen are used. The combination of these materials allows you to create a fairly reliable waterproofing material, the effectiveness of which increases with the number of layers laid.
Installation of roofing felt can be carried out in three ways:
- Mechanical. This technology of laying roofing felt on the roof is the most traditional and has been used for a very long time, which is due to the lack of alternatives. Mechanical installation roofing felt consists of fastening the material using roofing felt nails. The method is quite simple to implement, but is not very effective in terms of the durability of the structure - the presence of holes in the roofing felt negatively affects its waterproofing properties.
- Deposition. Fused roofing felt roofing technology has some limitations: firstly, special equipment is required to apply the coating, and secondly, this method is not suitable for combustible substrates. The installation technology involves the use of a gas burner, which heats the adhesive layer located on the underside of the roofing material.
- Gluing. For implementation this method Various mastics with adhesive properties are used. All laid layers of roofing material are coated with bitumen mastic and securely glued to the roof surface. This method is considered the most effective today, since the result is a monolithic overlap of roofing felt on the roof.
Classification of mastics
Mastic for roofing felt is adhesive composition, allowing you to reliably and hermetically lay layers of roofing material. There are a lot of branded mastics that can be purchased at finished form, and if necessary, you can make a similar composition yourself. However, there is no particular point in this - most mastics are quite low in cost.
Mastic for roofing felt on the roof is made in two forms:
- Cold. Cold mastics are different in that they can be applied without preheating. In addition to bitumen, such mastics contain a solvent (gasoline, kerosene or diesel fuel). To prepare such compositions yourself, you need to take bitumen and solvent in a ratio of 3:7, melt the bitumen and mix with the solvent. After cooling, the roofing felt resin retains a liquid consistency. As a rule, cold mastics are more expensive and their consumption is higher, so it is advisable to use such compositions only for minor repairs or installing roofing felt on a small roof.
- hot. To make hot mastics, hard bitumen is used, which must be preheated during application. The manufacturing process looks like this: a thick-walled container is filled with bitumen approximately halfway and heated over low heat with the gradual addition of additives and oil. It takes more time to create hot mastic, and you can only work with it while it is warmed up. Such compositions are optimally suited for treating surfaces with large area– this turns out to be much more economical compared to cold mastics.
When creating mastic with your own hands, you need to very carefully monitor the temperature and consistency of the bitumen. If the material is processed correctly, it will emit gray light smoke and a slight hiss. If there is yellow smoke or bubbles, it is better to refrain from using this composition.
Using mastic for roofing
Roofing mastics are required to perform the following tasks:
- Gluing roofing felt. Applied to bottom side roofing felt mastic ensures its fixation on the roof. Each layer must be treated with mastic, and when laying, the material must be smoothed so that bubbles do not form under it. Roofing material laid on bitumen mastic provides reliable waterproofing roofs.
- Priming the base. Bitumen mastic is well suited for priming the roof base, which is necessary to increase adhesion between materials. This treatment is especially important if the roofing material will be laid on a concrete surface, which is distinguished by the presence of pores and a not very smooth surface.
- Roof repair. If the roof was made of roofing felt, then bitumen mastics are quite suitable for its repair. The fact is that during operation, roofing material acquires minor damage, to eliminate which a small amount of bitumen composition will be enough.
- Coating waterproofing. Mastics can be used as a separate material to create a waterproofing layer that protects specific surface from moisture.
Conclusion
For laying roofing felt, bitumen mastics are actively used, which increase the waterproofing properties of the coating and ensure its seamless connection. Working with such compositions is very simple, and if necessary, you can create them yourself, observing the required proportions and maintaining the optimal temperature.

In order to succeed good waterproofing roofing, we will need: RPP lining roofing felt, RKK roofing felt, and a knife for cutting roofing felt. Alternatively, before gluing the roofing felt, you need to check the base. It should be smooth, without cracks or potholes, and clean. All these shortcomings can be corrected using cement mortar and waterproofing mastic.
After this, you need to apply a bitumen primer. It should be applied using a roller or brush to ensure better adhesion to the surface, as well as sealing microcracks. should be stirred well. This mastic is thick, so the roofing material should stick to it without any problems. Then you need to try on the roofing felt: unwind the roll of roofing felt in the place where you are going to glue it, adjust it and make all the necessary cuts with a knife. Roll it up. Fitting will need to be done in those places where adjustment of the material is required.
Now you can do the gluing itself. It is necessary to apply mastic to the gluing area. Gradually unwind the roll of RPP roofing material onto a layer of mastic, while pressing it tightly to the base. Each subsequent layer should cover the joint of the previous one with an overlap of 10 cm. After the bottom layer of roofing material has been laid, the top layer of RKK roofing material should be applied. Installation of RKK roofing material occurs almost the same as RPP, the only thing that is needed in places of overlap additional expense mastics.
About 40–50 years ago, roofing felt was considered one of the main roofing materials; it was used not only on outbuildings, but also residential buildings. appeared today large number modern roofing materials with high performance characteristics. But new materials and technologies are also used for the manufacture of roofing felt, which has made it possible to significantly improve all its indicators. Now it has become much stronger and more durable, the service life has been significantly increased, subject to the production technology and use high-quality coating tightness remains for 25 years or more.
The main disadvantage of roofing felt is its low design parameters. In this regard, currently such coatings are made only on outbuildings and garages.
Availability of many types roll coverings led to the fact that all materials that use modified or ordinary bitumen as waterproofing are called roofing felt. This one is made on the basis of construction cardboard or non-woven synthetic materials, covered with bitumen. For additional protection from harmful effects tough ultraviolet rays crumbs made from natural or artificial stone. The reverse side has a plastic film or stone chips that prevent the turns from gluing together.
What types of roofing materials are often called roofing felt?
| Name of material | Technical description and performance characteristics |
|---|---|
| A modern roofing covering using frame fiberglass, reinforced fiberglass or polyester fabric as a base. The materials are durable, not afraid of direct contact with water, and flexible. Due to plasticity, it is possible to compensate for changes in the linear dimensions of a wooden roof and maintain the original tightness. For waterproofing, the base is covered roofing bitumen with various fillers and plasticizers. Top layer sprinkled with granulate, the bottom has a protective polyethylene film. Modified bitumen retains its plasticity even when sub-zero temperatures, which eliminates the appearance of microcracks. Service life is 15 years. |
| It is made on the basis of thickened construction cardboard, waterproofing is provided by modified bitumen. To enhance design and performance characteristics external surfaces are covered with stone chips. Cardboard cannot stretch, which is considered a disadvantage of rubemast. Technologists recommend covering the roof with at least two layers of material; the sheathing must be continuous. Rubemast cannot be glued; the material is fixed only with special nails or wooden planks. |
| The most durable coating, service life reaches 30 years. Impregnated with synthetic rubber, the base is durable fabric. The front surface is sprinkled with multi-colored stone chips - the design indicators are significantly improved. Fiberglass fabric is plastic, due to which minor fluctuations in the size of a wooden roof are leveled out. Not afraid sharp changes temperatures, can independently delay minor mechanical damage. |
| An innovative polymer-bitumen mixture, used both during new construction and during the repair of old roofing material. The wooden base can only be solid - sheets of OSB or plywood. The advantage is the complete absence of seams, and this is where leaks most often appear. Another advantage - high performance plasticity. Liquid roofing felt has high adhesion to all building materials, excellent resistance to UV rays. It is recommended to apply three layers, the surface must be completely dry. |
Before starting work on fixing roofing felt, you need to carefully study the markings. What does it say on the packaging?

Letter designations
On the packaging the manufacturer indicates the letters “K”, “P”, “E”, giving general characteristics material. According to the specified order of letters, roofing material can be roofing, lining and elastic. The letter “P” means that the roll contains roofing felt.
In addition to these inscriptions, the characteristics of the protective coating are given - fine-grained “M”, dusty “P”, coarse-grained “K”, scaly “Ch”, colored “C”.
Coarse-grained is most often made from natural granite and can withstand significant mechanical forces.
Fine-grained looks a bit like regular sandpaper, small fractions of purified river sand. Marine is not suitable, it does not have sufficient hardness indicators. The scaly one is made from slate and is shaped like the scales of small fish. Dust-like is used for materials used as a bedding layer for finishing roofing coverings. Made from talc or chalk.
Digital symbols
The packaging must indicate the weight of the roll and the quantity square meters, standard width 100 cm. The thickness of the roofing material depends on its specific purpose, for finishing coating wooden roofs the thickness should be between 3–4 mm. Thinner types may only be used as additional lining waterproofing layers.
How is roofing felt fixed on a wooden roof?
The developer chooses the fixation methods taking into account his desires and the characteristics of the roof. You need to decide on them before purchasing roofing felt; there are types that are suitable only for hot or cold fastening.
Important. For roofing felt you only need to prepare continuous sheathing. The smoother it is, the more reliable the coating.
The sheathing can be made from edged or non-edged edged boards, OSB or plywood. The gaps between the boards should not exceed 2–3 cm, the heads of the nails should be recessed, this prerequisite. The fact is that ordinary nails can stretch a little as the thickness of the boards changes or other fluctuations rafter system. As soon as the caps appear above the surface of the boards, the roofing felt will break through, and the leaks will have to be repaired immediately.
In what ways can roofing felt be attached to a wooden roof?
1. Using mastic or glue.
Reliable, fast and simple method. The only condition is wooden base must be dry, otherwise the degree of adhesion is insufficient. Currently in implementation huge selection There are different brands of mastics, but apart from the name and cost there is no difference between them. All of them are made using ordinary cheap bitumen. There is no need to use a modified mastic; the mastic is covered with several layers of roofing felt and is reliably protected from ultraviolet rays. But such cheap mastic can only be purchased if there are no elements on the roof that need to be sealed without further coating with roofing felt.
The mastic can be used cold or it must be preheated. Experienced roofers do not recommend using compounds that require heating. It's long and difficult. In addition, it is almost impossible for beginners to maintain the recommended temperatures. As a result, there are areas with cooled mastic, and the roofing material will not attach securely to them. But there may also be overheating of the material, if it is too high temperatures it also loses its original properties. And the last problem - you need to heat it with an open fire, and doing this on the roof is dangerous - there is a big risk of getting burned, an overheated composition can spontaneously ignite with all the very negative consequences.
IN lately A special glue for roofing felt has appeared, but it is rarely used for wooden roofs - it takes too much time to apply the composition to the surface wooden sheathing.
2. Deposition.
For this method, you need to buy a special roofing material; the surface is heated with a burner. You must work very carefully, wood is a flammable material. During heating, the special protective film melts, bitumen mastic becomes liquid.
Important. The quality of fastening the roofing felt to the roof depends only on the experience of the specialist. If you are encountering such work for the first time, it is highly recommended to practice. It is necessary to find out approximately the heating time of the roofing material, the speed of unwinding the roll, and the force of pressing the heated material against the sheathing.
Roofing felt can only be glued onto a continuous sheathing. If there are cracks on it, then the hot soft roofing material will fall into them, the surface will become uneven, and water will constantly accumulate in the recesses. Besides, sharp corners wooden sheathing reduces the thickness of the roofing material; leaks often appear in these places.

3. Special self-adhesive roofing felt.
The most modern and most expensive roofing material. Made from modified bitumen with increased adhesion properties. During fastening, the protective cover is gradually removed polyethylene film, the roofing material is pressed tightly against the surface of the sheathing with a special rubber roller. This material can only be used on a perfectly flat surface.
4. Using nails or wooden planks.
Traditional method, proven over many decades of use. The nails must have wide caps made of galvanized sheet steel. If they are not available, then you can cut galvanized steel squares yourself, but appearance the roof will deteriorate significantly.
Fastening with wooden slats is more reliable; two strips are fixed along the entire length. It is advisable to impregnate wooden slats with an antiseptic before use; during processing, the manufacturer’s recommendations should be strictly followed. Due to the fact that the overlap is not sealed, it increases to 15° minimum angle slope of the slopes and up to 20 cm overlap width.
Step-by-step instructions for attaching roofing felt
Let's consider example of fusing roofing felt onto a shed sloping roof . The continuous sheathing is made of edged boards 20 mm thick; metal drips are nailed along the perimeter of the roof.
Step 1. Take the rolls of roofing felt to the roof and prepare your tools. You will need a tape measure, assembly knife with a set of replaceable blades, metal square.
Step 2. Roll out the roll on the free surface of the slope, measure the length of the roofing material. It should be 10–15 cm greater than the width of the slope. Cut a piece of the required length for the metal square.
Practical advice. The material should be cut from the reverse side; crumbs significantly complicate the process. Keep the knife blade at an angle of approximately 30°; the smaller the angle, the easier it is to cut. Press the knife with great force; it should be constant along the entire length of the material.
Step 3. Prepare all the pieces in this way and roll the finished pieces into rolls. If the roof slope is smooth, then the rest can be cut according to one template. If there are differences, then it is much easier to slightly increase the length margin, and after fastening, cut off the excess. It takes a long time to measure each individual piece.
Step 4. Place the first strip of roofing felt in place and check its position. Make sure it lies as flat as possible.
Step 5. Light the burner and adjust the flame strength. Stand on the covering, bend a piece approximately 40–50 cm long from the edge of the roof.
Step 6. Gently heat the bitumen with a burner; the protective film should melt and the roofing material will soften. Before it cools, quickly roll the heated piece over your area and press it over the entire surface. This must be done in a timely manner; after pressing, bitumen should come out along the edges. This indicates that the heating temperature is selected correctly. We have already mentioned that it is advisable to practice on segments, and only after acquiring practical experience do work on the roof.
Step 7 Wait a few minutes to let the newly glued area cool down a bit. Roll the remaining piece of roofing felt into a roll.
Step 8 Go to the vacant area on the roof and start heating the roll. Drive the burner flame from average speed, never keep it in one place. It is necessary to immediately warm up only the easily accessible surface of the roll. As soon as the temperature reaches the desired values, roll out the roll and press the hot part to the base of the roof.
Step 9 Stand on the already glued area and continue working. The roll needs to be heated and rolled out without stopping, using your feet to press the roofing material against the sheathing.
All remaining pieces of roofing felt are glued using the same algorithm. Do not forget to overlap; in places where there is overlap, pay special attention to the quality of heating of the material. A small amount of bitumen should protrude along the entire length of the overlap, there should be no breaks. To guarantee, you can reheat the seams.
The final stage of work is heating the seams

Construction boards
This option does not require a burner, which simplifies the process; not every master has one. And working with a torch requires practical experience; inept actions can burn through holes in the material.
The roofing material will be fixed with wooden slats 2x3 cm soaked in antiseptics, ordinary nails 4–5 cm long. Covering the roof in two layers, the first along the slope, and the second across, with an overlap of 25–30 cm. A roof of 35 m2 will take approximately three hours, from It takes one hour to prepare and impregnate the slats with antiseptic.
Step 1. Nail to the rafters unedged boards, try to place them as tightly as possible. This will be a continuous sheathing under roofing felt. Secure wind boards around the perimeter of the roof.
Step 2. Bring the rolls onto the roof and roll them along the slope. As practice shows, there are often unscrupulous domestic producers coating, the roll may be missing about a meter of material. You need to keep this in mind when calculating quantities. Fix the roofing material along the edges with a construction stapler. Leave a bend of the larger length, then all ends will be carefully trimmed to fit the ruler. Before nailing with a stapler, carefully align the material and do not leave folds. There is no need to drive in a lot of staples, and there is no need to make extra holes. Use staples only along the edges; later these places are covered with top sheets. Using this algorithm, lay the first layer of roofing material, do not forget to constantly overlap.
Laying the following canvases and fixing their edges
Step 3. Proceed to laying the second coating, now do it across the slope, the overlap is the same as in the first case.
Laying the second layer perpendicular to the first and fastening with a batten
Step 4. Nail where there is overlap wooden slats. The distance between the nails is 25–30 cm, press the slats tightly. If the sheathing has unevenness, then reduce the distance between the nails; they should bend the lath and press it over the entire surface of the slope. To increase the reliability of fixing the slats, you can use self-tapping screws instead of nails, but this slightly increases the time of roofing work.
This completes the roof covering; if desired, you can install a drainage system. But ordinary outbuildings rarely have drainage.
It is better to work with the material in warm, dry weather; do not pay attention to the assurances of manufacturers who allow installation at low temperatures. None of them have yet managed to outwit the fundamental laws of physics. And they say that all bodies become harder with decreasing temperature, this automatically reduces the adhesion coefficient. Low temperatures create another problem. When it comes into contact with a cold sheathing, the bitumen quickly cools down and does not have time to penetrate deeply into the boards. As a result, the fixation strength is significantly reduced.
The base under the coating must be dry and clean. There is always a lot of small chips left on the surface of the boards; they should be thoroughly cleaned. You can use an ordinary broom or vacuum cleaner. Carefully inspect the surface; if, after warping, sharp edges of the boards protrude above the plane, then they should be planed. You can use manual or electric plane. There are no such tools - level the boards with a sharp ax or wood chisel.
To make work on steep slopes easier, make a special ladder. In the upper part it is fixed on the ridge, and the elongated steps will allow you to reach the edge of the rolled roofing felt. By the way, on such roofs you can lay roofing material only along the slope; the risks of water flowing in are minimal. Laying along the roof is much faster, safer and easier than laying across it.
Always follow safety regulations and do not work without a safety rope.
It is advisable to purchase a special carpenter's belt, with its help you will have all the tools at hand.
The greater the angle of inclination of the slopes, the greater the distance between the sheathing boards. But you should not abuse this; experienced roofers advise, if possible, to always make a continuous sheathing. In places where there is sagging, the roofing material, if it does not break through, will stretch out over time. And this also creates the risk of leaks.
You can find tips for painting roofing felt. There is no need to waste time and money. There will be no positive changes; on the contrary, the paint will fall off in pieces over time, and the roof will look like a dirty field.

On modern market there are many modern materials, however, roofing felt is usually one of the most sought-after and popular.
Why do consumers love it so much?
- ease of installation;
- use as waterproofing; low cost;
- quite cheap sealing of joints with its help.
Perhaps, along with other roofing materials, the only serious drawback is the not too long service life of the roofing felt coating.
Methods for laying roofing felt
Previously, sealing joints and installing material was very simple: a roll of material was rolled out, which was then nailed through a wooden plank.
This method of installation turned out to be leaky, and the coating was not able to last long.
The use of fusion methods such as the use of molten resin improved the quality of the work, but turned the procedure into a rather dangerous undertaking.
Fortunately, they were developed and began to be produced special compounds for gluing, practically safe to use. Even non-professionals and non-specialists can use them without difficulty.
Glue for roofing felt
This composition is a combined adhesive mass that includes several components. This is usually bitumen, suitable solvent, some kind of filler, as well as all kinds of additives.
The main purpose of the product is not only to glue the material to all kinds of surfaces, but also to seal the joints with it.
The trade offers many types of glue from different manufacturers. Each brand has its own advantages, but the main functional task remains the same.
Qualities and properties
Conventionally, all types of glue can be divided into compositions for cold and hot use.
Already from the name it becomes clear that cold mastic is used with very little heating and subsequent mixing with a solvent.
The hot analogue is heated to an average temperature of approximately 200 degrees before use, which takes much more time.
Such mastics are used for waterproofing foundations, ceilings, walls and other parts of structures and buildings.
Which brands are the most famous?
These include glue for roofing felt "TechnoNIKOL", Lepik na zimno, ASKOWIL and others.
Bitumen mastic
Bituminous mastic contains a number of resins and some chemical elements, qualitatively improving the adhesion of the material with various surfaces. With its help, roofing felt can be glued even to a damp surface without risking the quality of the connection itself. During the work, a layer is obtained that is resistant to aggressive compounds and water, which is not afraid of alkalis or acids.
The process of working with bitumen mastic
- Before the start of the event, it is advisable to prime the surface. The same applies to concrete surfaces.
- The adhesive mass is evenly applied over the entire area of the material.
- It is required to maintain an overlap of at least 10 centimeters.
- A primer is not required if you plan to glue roofing felt to roofing felt.
Bitumen-rubber mastic
This product is used no less often than simple bitumen mastic. It is made in a paste consistency, which has excellent adhesion to wood, drywall, concrete surface. The thick paste-like mixture does not flow when applied even to a vertical surface.
Mastic for roofing felt is safe for surrounding nature and for human health. It does not contain organic solvents, so it can be safely used on a balcony, terrace, garage, etc.
The process of working with bitumen-rubber mastic
- Before using the product, the working surface must be thoroughly cleaned: grease stains, dust and dirt are removed from it.
- All existing sharp edges must be rounded.
- First, the surface is coated with a special primer, which dries within two to three hours.
- Next, mastic is applied to it twice with a special metal spatula.
- After applying the initial layer of 1 mm, it should dry within 24 hours, only after which you can apply the mastic again.
Benefits of using glue
The most reliable method of roofing felt waterproofing is rightfully considered to be the use of bitumen adhesive for roofing felt.
Thanks to the mastic, a waterproofing monolithic sheet is obtained, which retains its integrity during long-term operation.
As for the cost of the product, cold and hot mastic have significant differences. For bitumen roofing felt glue of the so-called cold category, it is much higher, which is understandable: it does not require labor-intensive and lengthy preparation and is in fact already ready for use.

Hot and cold mastic for roofing felt - general information
Glue for working with roofing felt is a homogeneous adhesive mass, which is made using multi-component mixture technology. The basis for the manufacture of this adhesive is the following components:
There are two types of mastic - the so-called hot and cold. From the name itself, it is obvious that the use of cold mastic is possible with a short heating and mixing with a solvent, and before application, hot mastic must be brought to the required temperature, which on average should be about 200 degrees Celsius and such a mass takes much longer to cook.
The use of the described mastics is possible when waterproofing floors, walls, foundations and other elements of buildings and structures.
Advantages of using bitumen adhesive
The use of bitumen glue is rightfully considered the most reliable and effective way of arranging roofing felt waterproofing. The main advantage of using mastic over other methods of fastening roofing felt is the absence of air pockets when connecting joints of rolled material. Mastic allows you to achieve a solid monolithic waterproofing sheet that will serve for a long time without the risk of damaging the edges and joints of roofing felt sheets.
However, it should be noted that hot and cold mastics differ significantly in price range. Price of bitumen glue for roofing felt, which falls into the cold category, will be much higher since this type of mastic is ready to use and does not require long preparation.
How to glue roofing felt to cold or hot mastic?
Before how to glue roofing felt to cold or hot mastic, it is necessary to take care of the cleanliness of the working surface. The presence of construction debris, dust or other foreign objects on the treated area is unacceptable.
It is also necessary to take care of personal protection when working with bitumen glue - use gloves, a respirator and safety glasses. If the upcoming work involves being indoors and not outdoors, then care must be taken to ensure effective ventilation.
Before gluing the roofing material to the working surface, it is necessary to prime it to increase the strength of the base and improve adhesion.
On average, mastic consumption should be 1.5 - 2 kg per square meter. m. This indicator depends on many factors, however, failure to comply with the norm can significantly affect the quality of work.
To apply bitumen glue, a notched trowel with 4 mm teeth is usually used, and for hot mastic, the consistency of which is too liquid for a trowel, special brushes can be used, with which the glue is evenly applied to the work surface.
You can buy cold mastic for roofing felt in any specialized stores. In this case, you should pay attention to the compliance with GOST of the mastic manufacturing technology, the integrity of the original packaging and the deadline for use. The average shelf life of asphalt adhesive is approximately 12 months, so care must be taken when determining the quantity required. Today, there are varieties of bitumen adhesives that, thanks to unique technologies, can be used on wet surfaces or on surfaces with an aggressive chemical environment.
