Precryl 

Acrylic protection paint. Anti-carbonation coating

Description

PRECRYL is a waterproof coating based on acrylic resins modified with polyurethane highly weather resistant. It is especially designed for facades or indoor surfaces which need a good protection against deterioration caused by the aggressive environment.

PRECRYL is suitable for the protection of concrete surfaces sensitive to carbonation.

Application procedure

Preparation of the surface: The application surface (concrete, mortar, stone, brick, etc.) should be resistant, absorbent and clean.

Loose particles, such as oxides, grease, laitance, dust and other polluters should be eliminated.

Product preparation: Stir the content of the container to achieve a perfect homogeneity. PRECRYL is diluted with 20 to 25 % of water, according to the substrate porosity and the type of application. For a second coating, dissolve the product in 10% of water. An anticorrosive priming is recommended over metal surfaces.

Apply by a brush, a roller or a spray on surface free from dust, grease or old paint.

Product application: In general, two coatings of PRECRYL are applied by a brush, a roller or a spray. The second coating can be applied immediately after the first one has dried. This depends to a great extent on the thickness of the film, the relative humidity and the environmental temperature. At 20ºC and about 60 % humidity, a coating takes two hours to dry.

Tools cleaning: The tools and utensils should be washed with water immediately after use.

Recommended for

• Facades of buildings.
• Surfaces sensitive to carbonation.
• Plastic coating for interiors and exteriors.
  
• Concrete structures.
