Waterproof Hybrid, Polyurethane / Acrylic Water Based Roof Roof

KRAFT TOTAL PROOF PU HYBRID is a high quality hybrid roof sealant of polyurethane acrylic water base, high elasticity, crosslinked in the presence of UV radiation. It is easily applied on horizontal and sloping surfaces of cement, concrete, asphalt, asphalt membranes and old waterproofing coatings of any type, presenting excellent adhesion. It offers excellent waterproofing and withstands adverse weather conditions, the growth of microorganisms and UV radiation. It maintains its elasticity at low temperatures and perfectly follows the contractions and expansions due to large or abrupt temperature differences, preventing the appearance of cracks.
It does not favor the deposition of dust and dirt on the surface, so it does not get dirty easily, maintaining its whiteness and reflective properties in the long run. It is user and environment friendly as it does not contain solvents. It is certified as a cold material, presenting high reflectivity of solar radiation and high emission coefficient of infrared radiation, as a result of which the surface temperature of the roofs is reduced and the energy efficiency of the building is improved.

»To ensure good adhesion to the background, the surface is required to be dry, without irregularities, clean and free of dust, oils, salts, rust, loose paints and residues, puffy paints, etc. The moisture content should not exceed 15%. Remove psoriasis, fungi by mechanical grinding, wash with soapy water and allow the background to dry.
»It is recommended that the surfaces of fresh concrete, cement, plaster and asphalt be left to dry for at least 4 weeks, before the application of KRAFT TOTAL PROOF PU HYBRID.
»Use suitable KRAFT sealant to fill gaps, cracks and other worn surfaces.
»Before applying the KRAFT TOTAL PROOF PU HYBRID, make sure that there are satisfactory drains and the corresponding water outlets on the roof (gutters). In case of local stagnant water, fill the cavities with a suitable KRAFT repair mortar. Slopes should be at least 1.5% -2%.
»On absorbent surfaces (cement, concrete, etc.) apply a layer of KRAFT ECO DUR AQUA diluted with 80% water and let it dry.
»On non-porous surfaces (ceramic tiles, mosaics, metals, etc.) apply a layer of KRAFT EPOXY FLOOR PRIMER AQUA transparent and let it dry.
»On asphalt surfaces apply a layer of KRAFT TOTAL PROOF PU HYBRID diluted with 20% water and let it dry for 24 hours.
»Apply the material with a roller, brush, brush or air gun without dilution in two thick layers crosswise with 6 hours repaint interval.
»In difficult places, apply more thickness or more layers of material. You can also use special gauze and / or KRAFT HYDROGUARD NET to reinforce these points.

»Painting tools: Roller, brush, brush or airless gun.
»Cleaning: Immediately after application, clean tools with hot soapy water or detergent, as well as product residues.
»Dilution: Ready to use.
»Surface drying time: 2-3 hours, at 25ºC and 50% relative humidity (drying times are extended in wet / cold conditions).
»Minimum repaint time: 6 hours.
»Stir well before use and during application.
»Do not apply at temperatures below 5ºC and above 35ºC as well as above 65% relative humidity.
»It is recommended to apply KRAFT TOTAL PROOF PU HYBRID in hot weather conditions in the early morning hours, when the surface temperature of the roof is less than 30οC and not under direct sunlight.
»It is recommended to use the surface after 48 hours and depending on the percentage of relative humidity.
»The membrane acquires its full strength after 7 days in normal conditions of temperature and relative humidity.
»Do not apply in case of impending rain for the next 2 days.
