PRIMER SF

Single-Component Solvent-Free Polyurethane Primer

PRIMER SF is a single-component, moisture-curing polyurethane primer. It is water- and solvent-free and is designed for treating and preparing subfloors prior to the installation of wood flooring.

Thanks to its low viscosity and excellent penetration, PRIMER SF is particularly suitable for strengthening and waterproofing concrete and anhydrite screeds with a moisture level of up to 5% M.C. When applied in a single coat, the product can be used on substrates with a moisture level of up to 2.8% M.C.

PRIMER SF is particularly recommended for screeds with underfloor heating systems.

The absence of solvents makes the product safe for transportation and storage, as it is non-flammable. During application, PRIMER SF is odourless, making it suitable for use even in or near occupied areas.

Compared with water-based products, PRIMER SF provides significantly higher coverage and does not increase the moisture level of the screed.
