ELASTOMERIC MEMBRANE FLEXIBLE RESIN-BASED POLYMER IN AQUEOUS DISPERSION FOR WATERPROOFING SURFACES, BOTH INTERNAL AND EXTERNAL PRODUCT AND FIELDS OF APPLICATION WPPASTE is a paste product ready for universal use consists of polymer resins, mineral additives, and additives to improve the rheological characteristics and application of the product. WPPASTE is used in both outdoors and indoors, on walls and floors for waterproof plasters pre-existing and newly developed cementitious and gypsum-based plaster, concrete, cement screed, cement, lightweight objects. PREPARING THE SUPPORT The substrates must be clean, free of dust, grease and/or oily, dry and mature, with no loose and removable parts. PRODUCT PREPARATION WPPASTE is ready to use, it has a liquid creamy grey consistency, it does not need any kind of dilution nor the addition of third-party products such as cement, lime, gypsum, aggregates, etc... The application of WPPASTE must be done by hand using a roller and / or brush prior to mixing bucket with a metal spatula or whisk in low speed. Once dry, create a particularly bonded elastomeric membrane, waterproof and flexible. Before proceeding with the drafting of WPPASTE make sure the supports to be treated are dry and mature, are not dirty and inconsistent. In the presence of structural joints, joints between horizontal and vertical planes and along the perimeter drains, chimneys and whenever there is disruption of planarity of jet planes, position, following the completion of a first coat of WPPASTE, a waterproof tape composed of two layers of non-woven polypropylene and a layer of a thermoplastic elastomer. When the surfaces to be treated have some small cracking and / or crazing, it is recommended the use of a reinforcing mesh in polypropylene or fiberglass alkali resistant. WPPASTE apply two coats making sure that the first coat is completely dry (about 2 hours) before proceeding with the application of the second. It is possible to apply coatings (tiles, natural stone, natural stone), after complete drying of WPPASTE and not earlier than 24 hours after preparation, using high performance adhesives in class C2TE, C2TES1 and C2TFS1 according to EN 12004. WPPASTE can be applied in the following thicknesses: min 1 mm - max 2 mm for single coat.
