BK / Adhesion mortar for thermal insulation panels

• For adhesion of stone wool and polystyrene foam thermal insulation panels
• Cement based
• With adhesion and flexibility improving additives
• Included in the certified insulation system SAKRET ETICS EPS and SAKRET ETICS MW
• Water vapor permeable
• Water and frost resistant
• Grey colour

Processing 

Surface preparation
• The base must be dry and firm, all cracks and voids must be filled
• Clean the surface from less persistent 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)

Usage
• Mix SAKRET BK in a clean container with cold water until a homogeneous mass without lumps is formed
• If the wall is flat (unevenness <10mm/m), then apply SAKRET BK with a toothed spatula (tooth size - 10mm) on the entire surface of the thermal insulation panel and stick it to the base
• If the wall is uneven, then apply SAKRET BK on the edges of the heat insulation panels (~5cm wide and 2cm high) and put 6 balls of the material on the surface of the panels, then stick to the wall
• If the thermal insulation panel is made of mineral wool, then SAKRET BK is first rubbed into the surface of the panel
