Product Description
Acrylic waterproof coating for metal roof is made of self-crosslinking acrylic waterproofing emulsion and filler. It is specially designed for coating on metal surface. It can be combined with woven polyester fabric to form the joints, joints and perforations of metal roofing. The complete waterproof system provides a perfect solution to solve the congenital leakage of metal roofing. At the same time, the coating material has fatigue resistance, aging resistance, low temperature flexibility and flexibility, which are completely suitable for open air environment and metal characteristics.
Characteristics
Construction Method
The waterproof part is determined:
Metal panel lap joints, intersections with the parapet wall, fan joints, protruding roof ducts, air conditioning ducts, lighting panels, roof ridges, gutters, rivet firmware and other weak parts.
Waterproof parts treatment:
A. Requirements: Ensure that the metal roof panel is firm and the waterproof parts are free of dirt and dirt.
B. Treatment: If necessary, replace or add firmware, grind the dirt and dirt, remove dust and other dirt, until the metallic color is present, and then apply primer.
Construction process:
1. Base treatment of each part:
Lap joint: Apply the primer coating, spread the 15~20cm wide sewed polyester cloth on the lap joint, and then fully coat and infiltrate with the primer coating.
Raised/firmware: chimney, vent, fan port, etc., need to paint around, spread the size and shape of the woven polyester cloth, paint on the cloth and fully infiltrate, to ensure that Bubble, no wrinkles.
Gutter: Gutters, seams, etc. need to be treated locally, and then painted, consistent with the above.
2. Brush the heat reflective coating:
After the base layer treatment of each part is done, apply one to two heat-reflective metal roofing special waterproof coatings in the waterproof area, and the coating thickness should not be <0.5mm.
Reference dosage: 1.0mm thick coating film, the total amount of coating is about1.8~2.0kg/.
Notes:
1. Do not apply below 5 ° C or in the rain.
2. After construction, before drying and film formation, care should be taken to avoid strong sunlight exposure, and rainwater erosion should be avoided.
It is mainly used for waterproofing of roof and wall of steel structure factory.
