BAK-F / Reinforcement / adhesion mortar for use in low temperature conditions

• For work at low air temperatures from 0°C to +20°C
• For adhesion and reinforcement of stone wool and polystyrene thermal insulation panels
• Cement based
• Reinforced with polypropylene fibre
• With adhesion and flexibility improving additives
• Water vapor permeable. Water and frost resistant
• Grey colour

Processing 

Surface preparation
• Surfaces must not be covered with frost, ice or snow and the surface temperature must be ≥2°C
• The base must be dry and firm, all cracks and voids must be filled
• Clean the substrate from loose and/or separable layers
• Particularly dense and/or smooth surfaces should be treated with an abrasive material
• Highly absorbent surfaces must be primed with SAKRET BG primer or SAKRET UG primer (diluted 1:3)
Reinforcement of thermal insulation panels
• Apply SAKRET BAK-F on the heat insulation plate in an even layer (up to 5mm), pull it out with a toothed trowel, embed the alkali-resistant reinforcing mesh in the mass and level it with the flat trowel so that the reinforcing mesh is completely covered with SAKRET BAK-F
• If the thermal insulation panel is made of mineral wool, then SAKRET BAK-F is first rubbed into the surface of the board
Adhesion of heat insulation panels
• If the wall is flat (unevenness <10mm/m), then apply SAKRET BAK-F with a toothed spatula (tooth size - 10mm) on the entire surface of the thermal insulation board and stick it to the base
• If the wall is uneven, then apply SAKRET BAK-F to the edges of the thermal insulation plates (~5cm wide and 2cm high) and put 6 balls of the material on the surface of the plates, then stick to the wall
• If the thermal insulation panel is made of mineral wool, then SAKRET BAK-F is first rubbed into the surface of the panel
