Substrate requirements: It must be clean, firm, leveled (without calendaring), no dust and oil. Defects like honeycomb and cracks should be repaired first. Internal & external corners need to camber. And dry substrates should be moistened.
Primer Treatment: Mix emulsion with water at the weight ratio of 1:1, then brush the mixture on the substrates.
Proportioning of waterproofing coating: Weigh materials as emulsion/cement=1/0.8(type I) or 1/1.2 (typeⅡ),or 1:2 (type Ⅲ). Stir the mixture to be uniform, fine and without aggregate structure before using.
Application: Brush the proportioned mixture on the base uniformly by 2-3 times until reaches the design thickness. Application interval replies on the drying time of the prior coating film. And per coating film should not exceed 0.8mm.
