WATERPROOFINGROOFTotal Proof PU S - KRAFT Paints

Solvent-based liquid-applied polyurethane membrane for waterproofing and protection of surfaces

KRAFT TOTAL PROOF PU-S is a liquid-applied, elastic, one component polyurethane membrane used for long-lasting waterproofing. It is based on pure elastomeric hydrophobic polyurethane resins, which cure by reaction with air moisture and result in excellent mechanical, chemical, thermal, UV and natural element resistance properties. When applied forms seamless membrane without joints. KRAFT TOTAL PROOF PU-S is used for waterproofing of roofs, balconies, terraces and under tile applications. It provides excellent adhesion to almost any type of surface with the use of suitable primer. Maintains its mechanical properties over a temperature span of-30ºC to +90ºC. It is resistant to frost and ponding water. It can be used for pedestrian and high traffic when it is fortified with KRAFT TOTAL PROOF TOP COAT. It complies with European Technical Guideline ETAG 005 and it is certified with European Technical Approval (ETA 16/0484).

Instructions

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 5%. 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-S.
» Use suitable KRAFT sealant to fill joints and cracks.
» Use suitable KRAFT repairing material to repair damaged surfaces.
» On porous substrates (concrete, plaster) apply one coat of KRAFT TOTAL PROOF PU PRIMER undiluted and allow to dry.
» On non-porous substrates (asphalt felts, tiles, fiberglass, steel) apply one coat of KRAFT EPOXY FLOOR PRIMER transparent undiluted and allow to dry.
|» Apply the material with roller, brush or airless or air-assisted spray gun crosswise in two coats. Apply the second coat after 12-18 hours, but not later than 48 hours.
» Apply KRAFT TOTAL PROOF TOP COAT with roller, brush or airless or air-assisted spray gun without dilution in one or two coats crosswise for the protection of KRAFT TOTAL PROOF PU-S. Apply the second coat after 7 hours.
» At problematic areas apply the material in thicker film. It is recommended to apply on these areas suitable reinforcement or KRAFT HYDROGUARD NET.

APPLICATION INSTRUCTIONS
» Tools: Roller, brush or airless or air-assisted spray gun.
» Cleaning: The tools and spillages may be cleaned immediately with KRAFT NITRO 1100 solvent.
» Thinning: No thinning is required.
» Dry to Touch: 1-2 Hours at 25ºC and 50% relative humidity (drying times are longer at lower temperatures and at higher relative humidity).
» Dry to Recoat: 12-18 hours.
» Stir well before use and during application.
» Do not apply at temperatures below 5ºC or above 35ºC or at humidity levels above 65%.
» The material is fully cured after 7 days in favorable weather conditions.
» No foot traffic should be permitted on the coated surface for 24 hours.
» Do not apply if rain is imminent and for 4 hours.
