The first layer coating: After polyurethane A, B groups were and xylene by 1:l.5:0.2 ratio (weight ratio) fit into the bucket spices, mix well with an electric mixer (about 5min ) polyurethane waterproof coating series, with a rubber scraper blade coating or paint brush a layer of paint, thickness should be uniform, scratch amount of 0.8 ~ 1.0kg / m preferably polyurethane waterproof coating quality, from the inside out back with the operation. The second layer of film: After the first layer of the coating, the coating cured to a tack-free time, material ratio method according to the first pass, the second time the coating operation, uniform thickness of the coating, blade direction must be Scratch the direction perpendicular to the first pass, the amount of the first pass with Scratch. Wall moist: Reason: rigid waterproof layer Bohou uneven. TROWELING not dense or leak wipe, wipe rigid waterproof layer after curing is not sufficient, Mortar dehydration, waterproof layer has tiny cracks. Maintenance: Synaptic epoxy powder processing method. With an equal amount of ethylene diamine and acetone reaction polyurethane waterproof coating, made of polyurethane waterproof coating composition imine acetone, adding a mixture of epoxy resin and dibutyl, epoxy resin content of 16%, and adding a certain amount of Synaptic powder, in clean, dry treatment after brushing the wall evenly.
