High-Quality Waterproof Fabric Polyethylene Polypropylene Composite Waterproof Membrane

Width 30 cm, Length approx. 30 meters
This is a polyethylene-polypropylene composite waterproof sheet (聚乙烯丙纶复合防水卷材). It is a durable and easy-to-install waterproof building material made by combining a high-molecular polyethylene (PE) layer with non-woven polypropylene (PP) long fibers on both sides, which have high adhesion to cement. Main Applications: The rough, three-dimensional mesh structure on the surface of the sheet strongly adheres to cement mortar, making it ideal for waterproofing and leak prevention in the following areas: Building rooftops, roofs, and floors; Bathrooms; Toilets; Kitchens; Basements; Reservoirs; Pools. Basic Installation Steps: Substrate Preparation: Clean the application surface of dirt and dust, and repair any unevenness or cracks. Areas around drainpipes and corners should be pre-formed with a gentle curve using mortar. Adhesive Preparation: Mix the dedicated polymer adhesive powder (glue) with cement and water in the specified ratio. Stir well until there are no lumps or sediment, creating a cement paste-like adhesive. Dampen the Substrate: Lightly sprinkle water on the application surface to dampen it (however, ensure no puddles remain). Sheet Application: Spread the prepared cement adhesive evenly on the substrate, and immediately lay the waterproof sheet while unrolling it. Use a trowel or roller.
