One component transparent primer for absorbent surfaces. Primer AS is a one component, epoxy-isocyanic primer in solvents used on absorbent surfaces, to help the bonding of Mapeflex PU40, Mapeflex PU45 and Mapeflex PU50 SL one component, polyurethane sealants for sealing flooring joints, with, respectively, low and medium modulus of elasticity. Primer AS may also be used when the joints are subject to frequent, prolonged contact with liquids or high mechanical stresses after sealing. Primer AS is ready for use. It is applied by brush in a number of coats, according to the porosity of the substrate. The successive sealant must only be applied once the primer is no longer sticky, after approximately 60 minutes at 23°C and 50% R.H.
Consumption 100-150 g/m2 (10-15 g/m for a joint with a depth of 1 cm).
