With the Soudal WBPR-21P Deep Primer, you effectively prepare absorbent and dusty subfloors before levelling or adhesive bonding. This solvent-free, water-based deep primer penetrates deep into mineral screeds, concrete, and anhydrite to bind residual dust and control surface absorbency. It prevents levelling compounds or adhesives from losing moisture too quickly, ensuring a solid base and dependable adhesion. Ready to use straight away, you apply it undiluted with a roller or brush for indoor projects. The primer appears white upon application and dries completely transparent. Supplied in a convenient 5 l jerrycan, it allows you to work cleanly without harsh fumes.
