P 51 Floor Primer

Ardex P 51 Primer is a solvent-free primer designed to be used over absorbent concrete for the installation of ARDEX underlayments and toppings. Ardex P 51 Primer improves the adhesion of Ardex products over standard absorbent dry concrete substrates. There are specific substrate preparation requirements for each ARDEX product in the readily available data sheets.

Features:

• For bonding ARDEX underlayments and toppings to appropriate substrates
• Non-porous substrates, burnished concrete, non-absorbent terrazzo, quarry, ceramic tile, and epoxy coating must be primed with ARDEX P 82 Ultra Prime.
