Add power into the JS slowly, stirring the mixture evenly until uniform with electric mixer for 5 mins. Proportioning of waterproofing coating: Weigh materials as emulsion/cement=1/0.8(type I) or 1/1.2 (typeⅡ),or 1:2 (type Ⅲ). If necessary to dilute with water, make sure the water weight can not exceed the JS’s 10%.
Brush thinly for several times with scraper evenly. The next brushing should conduct after the prior becomes hard drying.
Application method with fiberglass mesh: Generally needs two times brushing. Place the fiberglass mesh after the first brushing, and keep it leveled. Do the second time brushing after the prior coating film becomes surface drying but not hard drying.
