Breathable Exterior Wall Waterproof Coating
Description
Technical Parameters
Ordinary exterior wall waterproof coatings only focus on waterproofing while ignoring wall air permeability, leading to accumulated internal moisture, mold growth, coating blistering and peeling. Breathable exterior wall waterproof coating solves the contradiction between exterior wall waterproofing and air permeability through one-way moisture vapor transmission principle. Our breathable exterior wall waterproof coating takes special modified acrylic emulsion as base material, mixed with functional fillers. After film formation, micro-pore structure is formed to block liquid water infiltration while allowing internal water vapor of walls to discharge smoothly, realizing "waterproof without wall sealing". It can effectively reduce exterior wall condensation, mold and peeling problems with good weather and anti-fouling performance for stable long-term outdoor use. It has been applied in many old residential and commercial building exterior wall renovation projects to thoroughly solve repeated mold and peeling troubles of old walls.
Many so-called "breathable" exterior coatings on the market are only gimmicks with poor actual waterproofing or insufficient air permeability still causing wall problems. Our product precisely balances waterproof and breathable performance through accurate control of micro-pore size of film, with zero leakage under 0.3MPa water pressure and excellent water vapor transmission rate. Adopting water-based environmental formula without irritating odor, it can be directly used as exterior waterproof base layer with good compatibility with various exterior paints and stone paints. It can be brushed, rolled and sprayed on new and old walls. For agents, this product highlights core exterior wall pain points with obvious differentiated selling points, very suitable for old wall renovation and new residential markets to stand out in fierce exterior coating competition and gain more client recognition.
