Dry powder mineral mixture for preparation of a solution intended for fastening of elements of thermal insulation systems such as mineral wool (MW) and expanded polystyrene (PPS) plates and formation of a reinforcing layer in ThermoELF thermal insulation systems.
The surface of the base must be clean, dry, capable of loading. Contaminants and substances that reduce adhesion, for example: formwork oils, mortar residues and other materials, as well as painted exfoliating coatings must be removed.
Minor surface irregularities must be leveled with Klebe -und ArmierungsMasse AM 195 or KlebeMasse KM 193, the thickness of the leveling layer must not exceed 10 mm. Highly absorbent surfaces as well as dust-contaminated surfaces must be thoroughly cleaned and treated with UniGrund fixing primer or GrundKonzentrat primer concentrate. Substrates with a glossy surface must be roughened and treated with Acryl-PutzGrund 117.
Preparation of the solution
The contents of the package "Klebe -und ArmierungsMasse AM 195" (25 kg) must be carefully poured into a container with 4.5 ÷ 6.0 liters of clean water at room temperature and mix with an electric stirrer at low speed until a solution of uniform consistency. Leave the solution for about 10 minutes and stir again. If necessary, it is possible to adjust the consistency of the solution with a small amount of water. Depending on the weather conditions, the time of use of the solution is approximately 2 hours from the start of mixing with water. It is forbidden to re-dilute the solution, which has started to harden and lose mobility, with water for further use. Importantly! When mixing the solution, always take into account the exact amount of water indicated on the package. At the mechanized drawing it is necessary to be guided by the instruction on operation of the equipment.
