installation of styrofoam
Among the huge number of existing adhesives must be selected such that would meet the following requirements:
- It provides good adhesion to any surface;
- resistant to temperature and other weather extremes;
- easy to use and does not form sag;
- It is not a part of poisonous, toxic substances.
Useful advice! When working with a mixture of polystyrene can not be used with aggressive solvents in the composition. They destroy the material.

Glue for expanded polystyrene for external works: species
The adhesive mixture may be produced in various forms. This can be a special compound that must be diluted on their own or finished solutions. for Penoplex adhesive should not contain strong solvents, such as acetone, benzene. Such compounds may be dissolved heater, burning them in a big hole. They also should not be:
- formaldehyde;
- linseed oil;
- diethyl ether;
- toluene;
- kerosene;
- xylene.
Scheme insulation exterior wall using polystyrene plates
bitumen adhesive
Such adhesive compositions consist of a special light solvent which does not affect the polystyrene foam, and plasticizer directly bitumen. Such mixtures are quite popular, they are sold fully prepared in small buckets, which greatly facilitates their use.
The bituminous adhesive Penoplex
Before applying a bituminous adhesive surface of the walls should be thoroughly dried, sanded and primed. On the basis should remain dust, dirt, rust and other stains. For applying the composition using a special comb spatula. With it, a thin continuous layer of wavy lines are laid on the wall, after which the plate is glued. Clutch polystyrene to the surface occurs in the first 20 minutes, so in this period require additional fixation of props or some cargo.
EXAMPLE heater assembly using mastic BiLEM
Such adhesive is resistant to gasoline, various oils, acids and ultraviolet light. It provides additional insulation against moisture whole insulation system.
Cement and polymer cement
Such a structure can be used both indoors and outdoors. Cement-polymer adhesive for expanded polystyrene for the exterior is ideal for laying on concrete Penoplex, shlakoblochnogo or brick walls. Adhesive of this type is quite firmly adheres the polystyrene plates, but requires a fairly deep priming any surface. They are sold mainly in the form of a dry powder, which requires dilution according to the instructions.
Application of cement-adhesive polymer
By existing Portland cement in the mixture are added various polymers, which allows the finished adhesive be quite pliable and easy to apply. The resulting solutions are stable to high humidity, low temperatures and do not break down over time.
Installation of insulation to the wall
Polyurethane adhesive foam
This type of adhesive composition is radically different from the above. It is sold in cans and is used as a normal polyurethane foam. polyurethane glue polystyrene for the exterior has high adhesive properties, and has a number of other important advantages:
- easy to use;
- dries quickly;
- is economical consumption;
- is not exposed to a variety of extreme weather events;
- It does not spread;
- It has a high resistance to frost.
Polyurethane adhesive foam is sold in cylinders
Quality Penoplex bonding using adhesives foam polystyrene for the exterior rabotznachitelno above. No need for constant monitoring of the correctness of the preparation of the composition, as well as the recommended proportions. This adhesive mixture does not require mixing. Full strength is typed for about 2 hours, whereas the bitumen and cement grout is required not less than 6. One such balloon adhesive replaces more than 25 kg of powder.
Application Instructions Convoluted foam-adhesive
Glue the foam does not require continuous application, which is why it is economical. Apply it directly on the polystyrene plates at the edge around the perimeter and in a few extra points for a stronger grip. It also requires coating the joints to lock Penoplex sheets together.
Useful advice! Glue the foam must be applied with a special gun construction. It can be used prokleivat gaps formed between the plates.
To extrude polyurethane adhesive used special nozzle gun
Consumption of adhesive compositions
Before purchasing the selected adhesive for foam polystyrene for external works to determine the amount thereof, it is necessary to calculate the future composition of consumption. Exact figures are calculated, of course, is impossible, because they can depend on the material of the wall, it absorbency, but some data may be obtained by consulting the instruction of manufacturer.
The average consumption of different compositions:
| adhesive composition | amount |
| Dry mixes | 500 gr. / m² |
| bituminous compositions | 800-1000 gr. / m² |
| Polyurethane adhesive foam | 1 bottle to 8-10 m² |
From high-quality thermal insulation depends primarily on the health of the building and the people living in it. The choice of adhesive is used in the external insulation - an important task. After reviewing the description of the main adhesives for polystyrene as well as to methods of their application, you can choose the ideal composition suitable specific surface.
