Scope 1: indoor and outdoor concrete structures, masonry mortar walls, floors; 2: Bathroom, kitchen, ground floor, balcony, pool floor and wall waterproofing; 3: For paving stone, tile wipe the bottom, wood flooring, wallpaper, gypsum board before processing polyurethane waterproof coating performance, up to prevent moisture and salt contamination effects. Base surface (substrate) treatment: 1: The substrate must be firm, smooth, clean and free of dust, grease, wax, mold release agents and other substances, and other debris; 2: The surface has pores, cracks, inequality defects shall previously patched with cement mortar smooth, paste plastic strip joints proposal, the node must add a layer non-woven, filling nozzle orifice is recommended to use grout filling; 3: yin and yang corner should be wiped into the arc-shaped (or V type); 4: Make sure the base surface sufficiently moist, but not out of water; 5: poured concrete surface (including the plaster surface) in the pre-construction should be allowed to dry completely. Features 1, slurry cement-based active ingredients can penetrate the surface of the micro-cracks crystalline form a dense waterproof layer. To cover small cracks waterproof coating to resist a slight concussion; 2, construction in the wet base surface, without making a protective layer of mortar, tile, etc. can be directly attached to the follow-up process; 3, crystalline material deep in the end nonporous polyurethane waterproof coating evaluation, impermeability high compressive strength, with positive side and a back surface of the waterproof function; 4, non-toxic, harmless, can be directly used for drinking water pool and fish pond; 5, the coating has a depressive effect of mold growth, can prevent moisture salt copies of pollution of finishes.
