White 5Kg - 725019 20Kg - 725020
Waterproofing liquid membrane, in aqueous dispersion, of polyurethane acrylic hybrid technology that, once dry, forms an elastic, waterproof and UV-resistant film. Versatile product, suitable for waterproofing and protective coating, ultra-reflective in white to improve insulation capacity (SRI 106).

Instruction for Use

Waterproofing paint for finishing roofs: Before use, shake the product until it is perfectly homogenised. Apply a coat of primer, with a brush or a wool roller diluting REVESTIDAN® PROTECT COOL ROOFING in the proportion of 3 parts by volume of the product to 1 part of water, making sure that it penetrates well into all cracks or fissures. Once the primer has dried (approximately 24 hours after application under normal conditions of temperature and relative humidity), apply successive coats of undiluted REVESTIDAN® PROTECT COOL ROOFING until a coverage of 2.0 kg/m² excluding primer is achieved (minimum 2 coats excluding primer). Do not apply a coat until the previous coat is completely dry. It may be necessary to reinforce the singular points with a synthetic fabric reinforcement.
Waterproofing paint for finishing roofs on vertical elements: Apply the product before use, shake the product until it is perfectly homogenised. Apply a coat of primer, by brush or wool roller, diluting REVESTIDAN® PROTECT COOL ROOFING in the proportion of 3 parts by volume of the product to 1 part water, making sure that it penetrates well into all cracks or fissures. Once the primer is dry, apply successive coats of undiluted REVESTIDAN® PROTECT COOL ROOFING until a coverage of 2.0 kg/m² without primer is achieved (minimum 2 coats without primer). Do not apply a coat until the previous coat is completely dry. Cure by evaporation of water within 24 hours at 20-25 °C and 50% relative humidity. Dry to touch time approximately 4 hours at normal temperature and relative humidity. Drying time between coats, approximately 8 hours at normal temperature and relative humidity. It may be necessary to reinforce the singular points with a synthetic fabric reinforcement.
