Ardex P51 – Primer & Bonding Agent 5L

ARDEX P 51 is a water-based primer, precoat, bonding agent and pore closer for concrete substrates. As a pore closer, ARDEX P 51 prevents air bubbles rising from substrates and creating defects in the underlayments.

Application:

• Internal dry surfaces only

USE
Water-inhibiting primer, precoat, bonding agent and pore closer. Priming concrete to take finishing, repairing and levelling compounds. As a pore closer on concrete and cement screeds

• It prevents air bubbles rising from the substrate in subsequent finishing layers.
• It prevents any mixing water being drained in subsequent finishing layers.

Bonding agent on smooth concrete for gypsum-bound wall finishing compounds.
Protective coat against dust formation on finishing and repairing compounds, which are to serve as wearing surfaces for a short time.
Internal applications only.

Coverage:

• 6-10m²/L onto porous concrete
• Up to 50m²/5L container when diluted with 10L water

Drying Times:

• From 1hr depending on temperature, ventilation and substrate conditions

DIRECTIONS FOR USE
This product is used diluted with water, to prepare internal surfaces to receive cement-based levelling compounds, adhesives, screeds as well as plaster-based materials, improving adhesion and inhibiting penetration of water. It is used as a pore sealer on floor surfaces to prevent air bubbles rising through subsequently applied subfloor smoothing and levelling compounds.

SUBSTRATE
The substrate must be dry, porous, firm and free from dust and release agents.

APPLICATION
Apply diluted ARDEX P 51 (refer to table) evenly with a soft broom. DO NOT use paint rollers, mops or spray equipment. DO NOT leave any bare spots. Brush off puddles and excess primer. Allow to dry to a clear, thin film (minimum 3 hours, maximum 24 hours). DO NOT install ARDEX floor levelling cements before primer has dried thoroughly. Primer can be applied the day before. Use clean container.
Dilute 1:2 with water as a pore closer for porous concrete sub-floors and ceilings.
Dilute 1:3 with water as a primer and bonding agent on absorbent substrate.
