Knauf Schnellgrund is a high-performance, yellow-pigmented primer designed for rapid application on floor surfaces. Solvent-free and alkali-resistant, this hydrous primer ensures optimal bonding between substrates and subsequent flooring layers. It is ideal for both interior and exterior use, providing excellent adhesion adjustment on normally or low-absorbent and non-absorbent substrates such as calcium sulphate screed, gypsum fibre boards, mastix asphalt screed, and cement-based boards.
Its quick-drying properties allow for efficient workflow, making it a reliable choice for professional flooring installations. The primer remains slightly tacky even after drying, further enhancing adhesion for subsequent coatings. It is ready to use and can be easily applied with a roller or brush, ensuring a uniform and fully covering layer.
For best results, ensure that the substrate is clean, dry, and free from debris, grease, or curing agents. The drying time is approximately 2 hours under standard conditions, with variations depending on temperature and humidity.
Estimated Coverage:
62.5m2 per 5kg tub, when used on Knauf Brio and Knauf GIFAfloor.
35m2 per 5kg tub when used on Sub floor dependant on conditions
