PRYMER SF 1105 (A+B)
PRYMER SF 1105 is a two-component water-based epoxy primer developed for dusty subfloor, with a multi-layer application,it works as a moisture barrier. It is resistant to the inverse hydrostatic pressure according to the law UNI 8298 part 8. PRYMER SF 1105 is suitable for consolidation of subfloors on radiant heating. It is also recommend as a promoter of adhesion for anhydrite subfloors.

¤How to use :
Restoration of dusty subfloors Clean the subfloor to be treated by eliminating totally any trace of oil, grease, wax, or paint spots. The subfloor must be free from cracks. Mix componentAandB(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%). Adhesion promoter for anhydrite subfloors Sandpaper properly the anhydrite subfloor with large-grains paper till you get a white powder. Vacuum clean the surface well and apply one coat of PRYMER SF 1105 diluted at 10% with water, applying 150 g/m².
Moisture barrier:
PRYMER SF 1105 is able to create a moisture barrier on foundations of 6cm in depth and Residual Humidity of 5%, measured with the carbide method. Clean the subfloor 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, SIGOL, ADESIVER HERCULES,
ADESIVER 327 PU (see relative technical data sheets). The total quantity of PRYMER SF 1105 to ensure the correct creation of a moisture barrier is at least of 400 g/m². 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.
