Product Description

Mapei Malech is an acrylic resin undercoat in water dispersion to even out the absorption of substrates before applying other products.

Best Uses

Mapei Malech is used as a primer for wall surfaces in general (e.g. concrete or repairs with cement mortars) before applying a coloured finishing coat of Elastocolor range product and Quarzolite range product, as a regulator of the substrate absorption and as an adhesion catalyst.

Mapei Malech can also be used in the Aquaflex System cycle for permanent encapsulation of asbestos as a primer for covering layers of Aquaflex.

  • As a primer on well cured new or old renders as long as they are not damaged, before applying a coloured finishing coat of Elastocolor or Quarzolite range product.
  • As a primer over old paint, even if slightly chalky, before applying Elastocolor, Quarzolite or Colorite coloured finishing coat.
  • As a primer on surfaces that need to be treated in enclosed or poorly ventilated environments because Malech is odourless, before applying Elastocolor or Elastocolor Rasante.


Mapei Malech is a micronized acrylic resin based primer in water dispersion that, once applied on the surface, penetrates better than traditional water based primers. Malech is odourless and solvent free, therefore can be applied in enclose or poorly ventilated environments. Because of Malech's formulation, it ensures the consolidation of chalk present on surfaces that need to be treated.

  • Mapei Malech is ready for use but can be diluted 30-50% of water for surfaces with low absorbency
