Description

Mapei Malech is an acrylic water-based primer. Malech is a micronized acrylic resin based primer in water dispersion that, once applied on the surface, penetrates better
than traditional water based primers. As it is odourless and solvent free, it can can be applied in close or poorly ventilated environments.

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 from the Elastocolor, Quarzolite and Colorite range, used as a regulator of substrate absorption and as an adhesion promoter.

Features & Benefits

  • Penetrates better than traditional water based primers
  • Odourless and solvent-free
  • Formulation ensures the consolidation of chalk present on surfaces that need to be treated
  • Deep penetration into the surface slows down the formation of efflorescence



Recommendations & Limitations

  • Do not use Malech on metal surfaces
  • Do not apply Malech on wet surfaces
  • Do not apply Malech at temperatures below 5°C



Substrate Preparation

New surfaces that need to be treated or small repairs with repair mortars must be cured, perfectly clean, sound and dry. Remove from the surface all traces of oil or grease and any loose material that is not perfectly bonded.

Seal any cracks and repair deteriorated surfaces. Seal any porous sections and level any uneven parts of the substrate



Product Preparation

Interior application: Dilute Malech with water at a variable rate depending on the type of substrate. As a general rule, it is suggested a dilution Malech/water in a ratio of 1/1 for more absorbent substrates and 1/2 for less absorbent substrates, in order to avoid the forming of a glassy film on the wall surface.

Exterior application: Malech is used as it is in case of porous and very absorbent substrates. In case of other types of substrate, dilute Malech with up to 50% of water according to the absorbency, in order to avoid the forming of a glassy film on the wall surface



Application

Mix Malech before use and apply it with a brush, roller or spray. Protect from pouring rain for at least 12 hours. Malech can be painted after 12-24 hours depending on the environmental conditions.



Cleaning

Brushes, rollers or spraying equipment (airless) should be cleaned with water before Malech dries.
