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. Apply one coat of PRYMERFAST with an 6/8 mm roller or a 3x13cm or 4x14cm flat brush in a quantity of approximately 120-150 g/m2 in a regular, uniform way, creating a thin film and avoiding any pooling that could compromise the drying time and the hardening of reactive resins adhesives. The following bonding must be performed after 45-50 minutes and within 24 hours using only reactive adhesives, such as MS FLEX ADHESIVE and MS FLEX MAXI (see relative technical data sheets). Prior to the application of levelling compounds or in case the bonding is performed after 24 hours from the last coat, scatter the whole surface with quartz (0.8 mm ÷ 1.2 mm) on primer still wet. After complete curing, vacuum to remove any loose quartz. When the bonding is done after 24 hours and no quartz has been used, sand the surface with mono-disc machine using 36-40 grit sanding paper.
