Styrofoam is considered to be one of the most popular insulating materials. It is used for warming facades of buildings. The material is produced in the form of plates having different thicknesses.
Adhesive for extruded polystyreneis made on the basis of high-quality Portland cement. Modifying additives and quartz aggregates are added to it. The adhesive for expanded polystyrene is convenient and safe to work with. The solution has high adhesive properties to organic and mineral bases. The mixture helps to securely fix the insulation on the facade. After solidification, the solution becomes vapor-tight, water-resistant and resistant to temperature changes.
Before application, water is added to the dry mixtureroom temperature and mix with a drill with a nozzle. Water is taken at the rate of 0.18 liters per kilogram of dry mixture. As a result, a solution of a homogeneous consistency should be obtained. After the mixture is left for five minutes, then mix again. Ready-made glue for expanded polystyrene can be used for two hours. The material consumption is five and a half kilograms per square meter.
When using these two methods of applying the adhesive mixture, surface irregularities are compensated. In this case, the solution should cover sixty percent of the surface of the expanded polystyrene plate.
There is also a continuous method of depositionsolution for insulation material. This method is used in the presence of irregularities on the basis of up to three millimeters. In this case, the mixture is applied to the slabs evenly over the entire surface with a notched trowel.
Plates are installed immediately afterapplying glue on them. To better adhere the solution to the substrate, the insulation is pressed against the surface. Plates of expanded polystyrene are mounted one to the other in one plane. The width of the seam should not exceed two millimeters.
