ADHESIVE AND PLASTER FOR HEAT INSULATION

Portland cement, fractionated quartz sand, polymer additives, fibers.

For adhesion and plastering of expanded polystyrene (EPS) mineral wool (MW) and (XPS) insulation boards and application of plaster for the installation of reinforcing fiber mesh. Suitable for installation of external wall insulation systems on new buildings as well as improvement of the heat insulation of old walls and facades.

High strength, excellent adhesion to the substrate, polystyrene boards and reinforcing mesh, high vapor-permeability, water- and freeze resistant. The plaster protects the insulation layer and guarantees water resistance and crack resistance of the applied finish coat.

The substrate must be dry, sound, well cleaned of dust and dirt. Primer must be applied beforehand on highly absorbent surfaces.

Mix a bag of 25 kg of adhesive with 5.5 L of water. In a suitable container add the dry mix to the required quantity of water and mix with a mixing set for 10 min., then mix again and the product is ready to use. The ready mixture can be used within 60 minutes. Important – re-stirring the mixture increases the strength indices of the product.

If the substrate is smooth and even, apply the ready mixture on the whole surface of the insulation board with a square notch trowel forming ridges with the notched side of the trowel. If the substrate is uneven, apply the adhesive on the circumference of the insulation board forming a 4-5 cm wide strip, and apply “balls” of the ready mixture at several places inside this strip. When making reinforced plaster, apply the mixture on the surface of the substrate using the notched side of the trowel, apply the mesh overlapping the mesh pieces at the joints, press the mesh into the fresh mixture and smooth the surface with the trowel

Addition of other materials in the ready mixture is not allowed. The recommended temperature range of use is from +5°C to + 35°C.

For adhesion: from 4.0 kg/m2 to 5.5 kg/m2 depending on the size of the notches of the square trowel and how even the surface is. For plastering: from 4.0 kg/m2 to 5.0 kg/m2

To be kept in a dry and well ventilated place.
