Features and varieties of glue for roofing materials, installation methods

The glue used for bonding roofing materials must meet certain requirements. Indeed, the reliability and waterproofing characteristics of the roof, the reliability and strength of the foundation and other elements of the building structure directly depend on its quality. There are a huge number of brands in the construction market that offer customers glue for fixing roofing materials. Before choosing a suitable option, they study the characteristics of the substance and consumer reviews.

Material feature

Despite the fact that the roofing material is considered quite difficult to work with, its technical characteristics and low price made it popular in the construction industry. To properly seal the seams, choose a high-quality glue suitable for the characteristics of such a material.

As a rule, the composition of the substance includes the main component of bitumen, as well as a filler, a composition for dissolving and other auxiliary additives. There are two types of adhesives on the building materials market - for cold and hot mounting.They are used for all structural elements of buildings where roofing materials will be laid.

Installation methods

There are several ways to attach roofing sheets. The method is chosen depending on the design element and the skills of the master.

Mechanical

When using this method of fastening the material, the master will need battens and roofing nails. Builders rarely choose this method today due to its low efficiency. The roofing material is spread overlapping on the surface of the roof or other structural element. Do it with an overlap and nail it to the crate. Alternatively, wooden slats are placed along the joints and nailed with roofing nails.

There is also a material on sale, on the underside of which there is a self-adhesive film. Then the whole working process is greatly simplified. You just need to unroll the roll and press it as tightly as possible against the surface.

Merger

To use this method of laying, you will need special equipment, with the help of which the layer at the bottom of the roofing material is heated. The disadvantage of this method is that it is not suitable for use on combustible structures.

Bonding

In the case of choosing this method of installation, a special glue for roofing material is purchased. All layers are coated with putty and fixed to the base of the structure.

Among builders, this option today is considered the most reliable and effective, since it allows you to securely fix pieces of material on the roof or on another structural element of the building.

Varieties of mastic

There are different types of glue on sale, which are advisable to use for a particular method. The final result of the work depends on the correct choice of putty.

Cold

The special thing about cold glue is that it does not need to be heated before it is applied to the roofing material. The composition of such a substance contains not only bitumen itself, but also a solvent.It can be diesel, gasoline or kerosene. Preparing work staff is simple. Molten bitumen and solvent are mixed in a ratio of 3 to 7. After the substance cools, it will retain its liquid state.

The disadvantage of cold sealants is their high cost. These varieties are most often used for small repairs, when you need to repair a building part of insignificant size.

Hot

Working with hot varieties of roofing felt glue is a bit more difficult. For installation, hard bitumen is used, which is heated. A thick-walled container is filled with a substance about half its volume. It is heated over low heat, adding additives and oil in the process.

You can only work with this type of glue when hot. In addition, the preparation of the composition is much longer than in the case of the cold version. Therefore, builders use such glue when a large area needs to be covered with roofing material. It is more profitable than buying cold putty.

Review of popular brands

There is a wide range of roofing felt adhesives on the building materials market. Before buying, they familiarize themselves with the characteristics, advantages and disadvantages of a particular variety. The most popular formulations include products from these brands.

Technonikol

One of the most popular sealants is the production of the Russian company Technonikol. This type of glue does not need additional heating, therefore, the process of laying the roofing material is significantly simplified. It can be glued to the following types of surfaces:

• metal;
• concrete;
• cement.

It is possible to work with the substance at temperatures ranging from 5 to 35 degrees Celsius. The glue is applied to the lower part of the roofing material with a notched trowel. The thickness of the layer is 1 cm. Produced in buckets of 10 kg. Work with the adhesive is carried out in well-ventilated areas. Make sure that the substance does not come into contact with unprotected areas of the body and eyes. Do not use near sources of naked flames.

Abizol KL DM Tytan

Glue of this brand belongs to cold varieties. Once applied, a shell is created that is resistant to water, alkalis and weak acids. Abizol KL DM Tytan mastic is used for bonding roofing materials and waterproofing.

Before using glue for roofing material of this brand, prepare the surface. It must be clean and dry. Using a trowel or spatula, the composition is cold applied to the lower part of the material. The number of layers depends on the characteristics of the coating. 2-3 layers are applied for waterproofing, one is enough to mount the material. This glue cannot be used for interior work. Protect your hands and eyes with coveralls when working with composition.

AquaMast

It is also a cool option for rooftop installations. The multicomponent homogeneous mass consists of bitumen, solvent, processing aids and filler.Thanks to this putty, it is possible to glue roofing materials on ceramics, metal, wood, concrete and other types of surfaces.

Bituminous

The bituminous variety contains resins and some chemical ingredients, thanks to which the roofing material can be easily glued even on a slightly damp surface. The glue forms a protective film resistant to the effects of acids and alkalis.

In order for the craftsman to be satisfied with the quality of the work, it is recommended to apply a layer of primer before using the putty. The need for this action disappears only if the roofing material is glued to a similar surface.

How to glue roofing materials with your own hands

Before starting work, they are determined with the type of adhesive (cold or hot variety), prepare the necessary tools and protective clothing.

The process of laying the material looks like this:

1. The surface on which the material will be applied is cleared of the remnants of the old roofing material, and all dirt and dust particles are removed. If the surface is concrete, it is recommended to pre-coat it with a layer of primer in order to improve the adhesion characteristics. If the roof is wooden, then a coating is created from edged boards, all cracks and holes are closed.
2. Strips of the appropriate length are cut from the roll, while leaving a margin of at least 20 cm on both sides. If the slope of the roof does not exceed 3 degrees, it is permissible to mount the roofing material at once along the slope and across. If this indicator exceeds the standard values, but the work is carried out only along the slope. This will prevent water stagnation during storms and snowmelt.
3. After the surface is prepared, coat it with mastic, do not wait for it to harden, but immediately apply the roofing material with an overlap of 10 cm, then roll the material with a roller until it adheres completely on the surface. To make such a roller, a piece of metal pipe is used.
4. Then the next layer of glue is applied and the roofing material is shifted by half. In this way, all coating layers are mounted.
5. Before installing the final coat, get rid of accumulated air bubbles. If necessary, go over the entire surface with a roller. During the work, they make sure that all the joints are glued with high quality and that there is no deformation of the material.

Roof repair without heating

Not so long ago it became popular to purchase material with a self-adhesive base. This variety has its own positive and negative characteristics.

Benefits include:

• Stronger and more durable than other similar materials.
• Has a long lifespan.
• It is very easy to install, does not require the intervention of specialists for installation.
• It is possible to use the material on wooden surfaces.

Disadvantages include:

• Increased flammability.
• The need to make several layers between them.
• Increased fragility.

The step-by-step instructions for cold laying are as follows:

1. They clean the surface of dirt and debris, if necessary, dismantle the old coating.
2. Divide a roll of roofing material into sections of the required length and let them rest for a while.
3. Remove the protective film from the base and apply it to the structure, smoothing it to eliminate the air accumulated with the surface and the roofing material.
4. The following parts are offset by 15 cm to protect the seams from harmful penetration of moisture drops.

In order for the work to be carried out efficiently, they strictly follow the manufacturer's instructions and recommendations.
