ARDEX P51 Multi-Purpose Primer & Bonding Agent 5 kg

ARDEX P 51 is a versatile, water-based, solvent-free primer designed to seal and prepare a wide range of substrates—such as absorbent concrete, wood, gypsum, and non-water-soluble adhesive residues—prior to the application of ARDEX levelling and smoothing compounds.
