Surface Preparation & Primer

The substrate must be sound, stable, dry, and free of contaminants such as dust, grease, oil, paint, wax, curing compounds, and sealers that could interfere with adhesion.

Concrete and cementitious substrates should be mechanically prepared as required and primed with SikaLevel® Primer before applying SikaLevel®.

Proper preparation and priming are important for achieving a strong bond and consistent finished surface.

Important Application Notes

SikaLevel® is designed for interior use only and is intended as an underlayment beneath a finished flooring system. It is not designed to serve as the final exposed wear surface.

For installation instructions, limitations, substrate requirements, and current technical information, always refer to Sika’s latest Product Data Sheet and Safety Data Sheet before installation.
