Types of frost-resistant and waterproof adhesives for stone for outdoor use, how to choose a composition
Today on sale there are many effective types of frost-resistant and waterproof adhesives for stone intended for outdoor use. To choose the right product, you need to analyze its composition. The type of material for which the adhesive should be used is not insignificant. To achieve a strong and reliable fixation, you must strictly follow the rules for using the composition.
Main varieties
According to the main ingredient, all adhesives can be divided into 2 large categories, each of which has certain characteristics.
cement based
The basis of this glue is cement. For this purpose, the brands M400-M600 are suitable. They differ in affordable cost, but in terms of physical parameters they meet the construction requirements.
Based on epoxy resin and polyurethane
These are two-component substances with excellent properties. At a price, they are significantly more expensive than cement products. Extreme care must be taken in the manufacture and use of these substances. The main advantage of such formulations is considered high plasticity. The adhesives help to compensate for the deformation of the stone. It occurs when it expands under the influence of heat.
As a result, the strength increases, there is no risk of foaming in the seams, and microscopic cracks do not appear.
Such adhesives are expensive. Therefore, they are often used exclusively for processing seams or for processing certain fragments. The compositions are suitable for facades or swimming pools. They are also used for fastening decorative elements of the facade.
Basic requirements for the adhesive composition
In order for the adhesive to provide reliable and long-term fixation, it is worth choosing the right one. The composition must meet certain requirements.
High adhesion
Membership is considered the key selection criterion. This term refers to the strength of adhesion of the finish to the substrate. Adhesion is measured in terms of the force required to separate the bonded material from the wall. For difficult foundations and fixing large materials, this figure should be at least 1 Megapascal.
Strength
Good quality glue should be able to withstand 80 kilograms per square meter. This parameter makes it possible to use the substance for wall cladding with large or thick stones.
Moisture resistance
The substance should not change its characteristics under the influence of moisture. This will ensure a secure fit in all weather conditions.
Frost resistance
The adhesive should withstand a minimum of 35 freeze and thaw cycles. This does not mean the frame will last 35 years. Several temperature fluctuations can be observed during the same season.

How to use correctly
To successfully use the material, it is worth doing the following:
- Mix stone tiles from different packages and lay the pattern on a flat surface.Only then is it allowed to start editing. Thanks to the preparatory work, it is possible to simplify the choice of shades and sizes of tiles, as well as to speed up the process of fixing.
- It is worth removing all residues of coloring matter, dirt, oils, glue from the surface of the coating and covering with a layer of primer. Moisten the coating if necessary.
- If the stones are heavy, a reinforcing metal mesh is installed.
- After that, it is allowed to start preparing the adhesive composition. The result should be a strong, elastic seam. It is recommended to dissolve the composition in water. The result should be a thick mass. It retains its characteristics for 3 hours.
- It is recommended to apply the substance to the surface with a notched trowel. The same tool should be used to level the composition.
- The tiles should be covered with adhesive using a flat trowel. Its thickness should not exceed 1 centimeter.
- Then it is recommended to make bumpers out of glue and embed the stones in the wall with rotational movements. As a result, the excess substance will come to the surface. This technique seals the seam. It is recommended to remove excess glue.
- If the laying is carried out in rooms with high humidity parameters, then a hydrophobic solution should be used. This substance reduces moisture absorption and provides protection against salts and limescale deposits.
