Mapei Primer SN

Technical Information:

Primer SN is a two-component, fillerized epoxy resin-based primer applied with a roller, metal trowel or smooth rake according to a formula developed in the MAPEI R&D Laboratories. Coatings made with Primer SN prevent Radon (radioactive natural gas present in the soil) from penetrating inside buildings. Compliant with DIN ISO/TS 11665-13 standards, verified and certified by the IAF accredited laboratory for radionuclide analysis. Primer SN may be used as it is or mixed with Quartz 0.5 to improve adhesion of resin coating systems and even out surfaces. Thanks to its special formulation, Primer SN is characterised by its ability to penetrate into substrates and may even be applied on moderately damp surfaces.

Where To Use:

Primer SN has been specifically formulated to carry out preliminary priming treatments on surfaces before applying epoxy and polyurethane resin systems from the Mapefloor range, self-levelling cementitious mortars from the Ultratop/Ultratop Living range and of Ultratop Loft, to protect and coat civil and industrial floors, terrazzo floors and cementitious substrates in general.

Some application examples:

· Adhesion promoter for epoxy and polyurethane coating products in general. · Adhesion promoter for self-levelling and/or multi-layered coating products. · Adhesion promoter for flooring made from synthetic mortar. · Adhesion promoter for coatings from the Ultratop, Ultratop Living and Ultratop Loft ranges. · Fluid adhesive to seal cracks and make structural bonds.
