Water-based polyurethane membrane for protection and waterproofing of flat roofs
KRAFT TOTAL PROOF PU AQUA is high-performance water-based polyurethane waterproofing membrane special designed for superior weatherability and durability. Due to its unique formulation, it forms a tough seamless, flexible and breathable shield having exceptional weatherability, mechanical, chemical and UV resistance.
Its elasticity and toughness properties accommodate substrate movement in varying weather conditions and it oﬀers a high level of crack filling and bridging properties. It presents superior long-lasting resistance to dirt pick-up resulting high whiteness and solar reflectance over the years. It has a self-priming property when applied over most surfaces, it dries fast and it can be easily applied to flat and sloped roofs, including concrete, masonry and asphalt substrates. It is user and environmentally friendly waterborne formulation.
This coating is certified as cool coating and it provides an excellent, highly protective barrier which reflects the sun’s heat. In turn, this helps to cool surfaces and leads to a reduction of interior temperatures and improvement to building’s energy eﬃciency.

SURFACE PREPARATION AND APPLICATION
» To ensure proper adhesion to the substrate, the surface must be dry, clean and free of dust, oil, salt, rust, loose paint and residues, blistered paint etc. Maximum moisture content should not exceed 20%. Remove all moss, fungi and algae by mechanical abrasion and wash with soapy water and allow the substrate to dry.
» It is recommended that fresh concrete, stucco, plaster and asphalt surfaces are allowed to dry for at least 4 weeks before the application of KRAFT TAOTAL PROOF PU AQUA.
» Use suitable KRAFT sealant to fill joints and gaps.
» Use suitable KRAFT repairing material to repair damaged surfaces.
» On porous substrates (concrete, plaster) apply one coat of KRAFT ECO DUR AQUA diluted with 80% water and allow drying.
» On non-porous substrates (tiles, fiberglass, steel) apply one coat of KRAFT EPOXY AQUA FLOOR PRIMER Transparent undiluted and allow to dry.
» On bituminous substrates apply one coat of KRAFT TOTAL PROOF PU AQUA diluted with 20% and allow to dry 24 hours.
» Apply the material with roller, brush or airless or air-assist-ed spray gun crosswise in two coats. Apply the second coat after 6 hours.
» At problematic areas apply the material in thicker film or another coat. It is recommended to apply on these areas KRAFT HYDROGUARD NET reinforcement mesh.
» Tools: Roller, brush or airless or air-assisted spray gun.
» Cleaning: The tools and spillages may be cleaned imme-diately with soapy water.
» Thinning: No thinning is required.
» Dry to Recoat: 6 hours under favorable drying conditions.
» Stir well KRAFT TOTAL PROOF PU AQUA before use and during application.
» Do not apply at temperatures below 5°C or above 35°C or at humidity levels above 65%.
» All coats on warm weather conditions are recommended to be applied during the early morning hours, when the surface temperature of the roof is less than 30°C and not under direct sunlight.
» The material is fully cured after 7 days in favorable weath-er conditions.
» Do not apply if rain is imminent for the next 2 days.
» No foot traﬃc should be permitted on the coated surface for 48 hours after the application in favorable weather con-ditions.
» Store containers at 5°C to 35°C.
» Keep containers tightly closed when not in use.
