ARDEX P 51: Primer for Absorbent Surfaces
ARDEX P 51 is a versatile primer for indoor use, enhancing adhesion and sealing pores on floors, walls, and ceilings. It significantly reduces water absorption, prevents air bubbles in self-leveling applications, and is solvent-free. Suitable for various substrates including gypsum, concrete, terrazzo, and old screeds. Available in 10 kg and 25 kg canisters, it can be stored for 12 months in a frost-protected environment.
Usage Areas
Used as a primer and adhesion promoter, it seals pores and significantly reduces water absorption. For indoor use.
- On sanded and dusty surfaces, such as gypsum-based (calcium sulfate) screeds and self-leveling screeds
- On cement-based screeds before the application of self-leveling screed, repair mortar, and filler mortar
- On raw concrete and impermeable concrete surfaces, particularly those with added strength enhancers, terrazzo, sandstone, ceramic, and tile surfaces before thin plaster or tile adhesive applications
- As an adhesion promoter on renovation subfloors with residual screed and non-water-soluble old adhesive residues
- Reduces water absorption in concrete and cement screeds, preventing moisture loss in the mortar and air bubbles in self-leveling screed applications
- As a primer on gypsum, calcium sulfate-based surfaces, and chipboard subfloors before applying thin mortar or ceramic adhesive
- As a primer on raw concrete surfaces before applying gypsum and gypsum-based plasters
- To prevent dusting on plaster, screed, and other coatings in short-term applications

How can I prevent air bubbles in self-leveling floor applications?
To prevent air bubbles in self-leveling floor applications, use a primer like ARDEX P 51. It seals the pores and reduces the surface’s water absorption, preventing air bubbles from forming.
What primer should I use on concrete before applying plaster?
For concrete surfaces, use ARDEX P 51 as a primer. It enhances adhesion and provides a solid base for plaster applications, ensuring a smooth and durable finish.
How do I improve adhesion on old screeds before applying new floor coverings?
To improve adhesion on old screeds, apply ARDEX P 51 primer. It acts as an adhesion promoter and seals the surface, making it suitable for new floor coverings.
What can I do to reduce dust on plastered surfaces?
To reduce dust on plastered surfaces, apply ARDEX P 51. It prevents dusting and provides a clean, stable surface for further treatments or coatings.
How do I prepare a substrate for tile installation?
To prepare a substrate for tile installation, use ARDEX P 51 as a primer. It reduces water absorption and enhances adhesion, ensuring the tiles bond securely to the surface.
Can I use a primer on gypsum and chipboard surfaces before tiling?
Yes, ARDEX P 51 is suitable for gypsum and chipboard surfaces. It acts as a primer, reducing water absorption and providing a solid base for tiling or other coverings.
What is the best way to seal porous surfaces before applying self-leveling compounds?
To seal porous surfaces before applying self-leveling compounds, use ARDEX P 51. It effectively seals pores and reduces water absorption, ensuring a smooth and even application of self-leveling compounds.
How can I prevent moisture loss in mortar applications?
To prevent moisture loss in mortar applications, apply ARDEX P 51 primer. It reduces the water absorption of the substrate, maintaining the necessary moisture for proper curing and strength development.
What primer should I use on terrazzo or sandstone before plastering?
For terrazzo or sandstone surfaces, use ARDEX P 51 primer. It enhances adhesion and prepares the surface for plastering, ensuring a durable and long-lasting finish.
How do I ensure a solid bond between old and new concrete?
To ensure a solid bond between old and new concrete, apply ARDEX P 51 primer on the old concrete. It promotes adhesion and creates a strong bond, allowing the new concrete to adhere effectively.
