How to use
Restoration of dusty subfloors
Clean the foundation to be treated by eliminating totally any trace of oil, grease, wax, or paint spots. The subfloor must be free from cracks. Mix component A and B (ratio 1:1) manually or with electric tools, without creating excessive foam. When necessary, dilute with 10% of water before use. Apply 150 g/m² by roller. In case of subfloors with low absorption, dilute with higher quantities of water (up to 20%).
Clean the foundation to be treated by eliminating totally any trace of oil, grease, wax, or paint spots. The subfloor must be free from cracks. Mix component A and B (ratio 1:1) manually or with electric tools, without creating excessive foam. Apply 200g/m2 by roller. After curing (6 hours), apply a 2nd coat (200 g/m²). In case of subfloors with low absorption, PRYMER SF 1105 could create a superficial film. Spread some quartz (diameter 0,6 mm) on to the wet surface after the 2nd hand. The excess of quartz will be removed with a broom. We advise to use the following adhesives: UNISIL, ADESIVER ELASTIC, ADESIVER 501 EP, ADESIVER HERCULES, ADESIVER 327.
The total quantity of PRYMER SF 1105 to ensure the correct creation of a moisture barrier is at least of 400 g/m². The residual humidity allowed during the installation of a wooden floor is 5% in a 6cm thick substrate.
In case of powdery subfloors, the first coat as anti-dust has to be considered separately from the total quantity of 400 g/m² for moisture barrier.
