Primer NP
F.i. Primer NP is a water-based, ready-to-use bonding primer designed to improve adhesion of cementitious adhesives and levelling compounds to smooth, dense, or low-absorbent substrates. The product forms a textured, high-bond surface that enhances mechanical adhesion. It is suitable for internal applications and selected external uses depending on conditions.
