Anti-carbonation acrylic paint, for concrete products

Code: PRT.0117

Components: 1

Appearance: Thick liquid

Anti-carbonation, protective, decorative paint, pigmented for whitewashing concrete surfaces; based on acrylic resins in aqueous emulsion, it forms a film that is impermeable to water, with very low permeability to carbon dioxide but high vapour permeability, anchored by specific adherence and diffusion. Perfect for protective coatings of infrastructure projects in concrete.

Apply from 0.25 to 0.35 kg of PROTECH WAC per square metre of surface to be painted.

Use fields

Painting of protective, decorative and anti-carbonation finish, for walls, façades, concrete products, plaster, masonry, natural stones, porous supports in general. Specific for painting industrial works and infrastructure artefacts: bridges, viaducts, large prefabricated, etc.

Preparation of supports

The surfaces of application should be clean, free of any soiling, crumbling and non-adhering parts, or non-absorbent, dust, pre-existing paints, etc. Degraded or uneven surfaces should be reclaimed with products of the family REPAR or with adhesive cement mortars packaged in situ, based on BOND HG and polypropylene fibres READYMESH PM-180.

Despite it is a good habit to apply an acrylic paint after preliminary treatment of the surfaces with the suitable reinforcing fixative PROTECH FIX AC, in the case of PROTECH WAC this operation is not strictly necessary.

Use method

Apply the product in 2 coats, with a brush, roller or spray, diluting it with water according to the following dosages (% in weight):
- roller or brush = 10%
- spray = 15%-25%

Overcoat only after drying of the previous coat.

Application methods

- Brush

- Low pressure airless nebulizer

- Paint roller

- Sprayer

Tool cleaning

- Water

Permitted supports

- Cement-based or lime-based mortars

- Concrete

- Fiber-cement

- Plasters

- Prefabricated concrete

- Rock walls
