The adhesive mix WALLMIX F-12 is intended for fastening of front expanded polystyrene and mineral wool plates, and the installation on them of the hydroprotective layer reinforced by an alkali-resistant glass grid at warming of facades of buildings and constructions of various function. It is recommended for gluing of plates from extruded expanded polystyrene with a rough surface or with thermally put notches.
A mixture of cement with mineral fillers and modifying additives.
It is carried out in accordance with the requirements of DSTU-N B А.3.1-23: 2013 and DSTU-N B В.2.6-212: 2016. The surface must be dry, solid and cleaned from dust, dirt, oil, grease, wax and paint. Weak layers must be removed. Potholes, chips, cracks must be repaired with a repair mixture. Highly absorbent substrates must be treated with WALLMIX Universal or WALLMIX Interior deep-penetrating emulsion and left to stand for 4 hours. Weakly absorbent and smooth substrates are treated with WALLMIX BETONCONTACT adhesive primer before starting work and kept for 4 to 6 hours.
Pour the dry mixture into a container with clean water at room temperature in the proportion of 0.19-0.21 liters per 1 kg of mixture (4.75-5.25 liters per 25 kg bag). Mix thoroughly with a stirrer or low-speed drill with a nozzle to a uniform consistency without lumps and clots. Then soak the solution for 5 minutes and mix thoroughly again. The solution retains its adhesive properties for 2 hours.
Do not add other components to the mixture.
Execution of work.
When performing work, it is necessary to comply with the requirements of the current regulatory documentation.
Irregularities of more than 10 mm should be leveled beforehand by plastering the surface (for example, with WALLMIX C-13, C-15, C-16 or C-17 plaster mixture).
If the surface of the wall has irregularities of up to 10 mm, the adhesive solution is applied to the expanded polystyrene board (polystyrene) in strips about 50 mm wide at a distance of 20 mm from the edges of the board along its entire perimeter and additionally, in the form of separate adhesive spots in the middle of the board. Perimeter stripes must have breaks. The bonding area must be at least 60% of the board area.
If the surface of the wall has irregularities of up to 5 mm, the adhesive mixture is applied to the expanded polystyrene board (polystyrene) in strips about 50 mm wide at a distance of 20 mm from the edges of the board along its entire perimeter, and then in the middle. Perimeter stripes must have breaks.
If the wall surface has no deviations, the adhesive solution is applied in a continuous way over the entire surface of the thermal insulation board using a notched trowel with a notch size of 10×10 mm or 12×12 mm (for slabs of mineral wool and extruded polystyrene foam – only continuous application).
Before applying the adhesive to the mineral wool board, be sure to rub it into the fibers of the board. When using extruded polystyrene foam board, before gluing, it is necessary to carry out mechanical processing with an abrasive material on its glossy surface on both sides.
The width of the joints should not exceed 2 mm. The remaining adhesive must be removed before it hardens.
Possible irregularities of the heat-insulating layer of expanded polystyrene plates, which arose during the fastening process, are polished two days after gluing. Not less than 3 days later, the insulation plates are mechanically fastened to the base.
To create a leveling layer on mineral wool slabs: Not later than 14 days from the moment of fixing the thermal insulation boards with dowels, it is necessary to apply an equalizing layer of WALLMIX F-12 adhesive putty. The thickness of the leveling layer should be 1-2 mm. For further work to withstand a technological break of at least 1-2 days. For the installation of a reinforcing waterproofing layer: WALLMIX F-12 glue putty mortar is applied to even, carefully laid on the surface of the facade thermal insulation boards using a stainless steel notched trowel with a notch size of 10×10 mm. In the freshly applied layer of mortar, lay an alkaliresistant fiberglass mesh with vertical panels with an overlap of adjacent panels of at least 100 mm, then smooth the surface. The total thickness of the leveling and reinforcing waterproofing layer should be 3-5 mm.
Work should be performed at temperatures from +5 ° C to +30 ° C. The most effective result is achieved at a temperature of +20 ° C and a relative humidity of 60%. In other conditions, the operating parameters of the mixture may change. When performing work, the facade must be protected from direct sunlight, as well as high humidity (rain, fog, etc.).
Consumption of the mixture is 4.5-5 kg / m²
The mixture contains cement, which causes an alkaline reaction at the moment of hydration, therefore, when working, it is necessary to protect eyes and skin. In case of contact with eyes, rinse immediately with running water and consult a doctor.
The mixture must be stored in original sealed packaging in a dry place on pallets. The shelf life is 12 months from the date of production indicated on the package. Use damaged bags first.
25 kg paper bags with an inner polyethylene layer.
