Primer A Eco
Application

Suitable for internal and external use. For the creation of a suitable barrier to neutralize the expansive chemical reaction of gypsum and anhydrite-based substrates before laying ceramic tiles with mineral or cement-based adhesives.

Description

A single component, certified, eco-friendly, water-based surface isolation for dry, absorbent mineral, cement, gypsum or anhydrite-based substrates, suitable for use with EMICODE® Green Building. It is solvent-free and has very low volatile organic compound emissions.

Primer A Eco develops an isolating, cohesive film which neutralizes the expansive chemical reaction of gypsum or anhydrite-based substrates in contact with mineral mortars and adhesives. It reduces and regulates the absorption of highly porous substrates.

Features and benefits:

  • Solvent-free.
  • Binds dust.
  • Extends the workability of mineral adhesives and levelling products.
  • Suitable for heated substrates.
  • EMICODE® Green Building rating: Eco 5.
  • Contributes to LEED points.

Applications:

Suitable for internal and external use. For the creation of a suitable barrier to neutralize the expansive chemical reaction of gypsum and anhydrite-based substrates before laying ceramic tiles with mineral or cement-based adhesives.

– Suitable overlays:

  • Mineral adhesives, dispersed organic mineral adhesives.
  • Cement-based and dispersed adhesives.
  • Mineral finishing, levelling and self-levelling products.
  • Cement or gypsum-based finishing and levelling products and plasters.

– Suitable substrates:

  • Gypsum and cement-based plasters.
  • Mineral screed.
  • Anhydrite and cement-based screeds.
  • Gypsum brick and plasterboard panels.
  • High-density chipboard, cellular concrete.
  • Prefabricated concrete and fresh concrete castings.
  • Damp areas on external walls.

Consult manufacturer for recommended substrate preparation and substrates not suitable for the application of this product.
