Total Proof PU Hybrid

Hybrid elastomeric membrane for protection and waterproofing of flat roofs

KRAFT TOTAL PROOF PU HYBRID is high quality water-based polyurethane-acrylic hybrid UV crosslinking membrane designed for waterproofing roofs. Exhibits outstanding UV resistance and elongation. It resists cracking, peeling and mildew.
It can be easily applied to flat and sloped roofs, including concrete, masonry and asphalt substrates. This product provides outstanding weatherability, as well as exceptional protection from degradation caused by UV exposure. It presents superior long-lasting resistance to dirt pick-up resulting high whiteness and solar reflectance over the years. 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 15%. 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 TOTAL PROOF PU HYBRID.
» Use suitable KRAFT sealant to fill joints and cracks.
» Before applying, make sure the substrate has sufficient inclinations and gutters. Repair the areas of ponding water or other damaged surfaces with suitable repair mate-rial of KRAFT. The inclinations should be at least 1.5%-2%.
» On porous substrates (concrete, plaster) apply one coat of KRAFT ECO DUR AQUA diluted with 80% water and allow to dry.
» 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 HYBRID diluted with 20% and allow to dry 24 hours.
» Apply the material with roller, brush or airless or air-assisted spray gun crosswise in two coats. Apply the second coat after 6 hours.
» At problematic areas apply the material in thicker film. It is recommended to apply on these areas suitable reinforcement or KRAFT HYDROGUARD NET.
