How to do a waterproof roof gutter simple and Water Leakage, the best you can do?
If you do waterproof coiled material construction, after cleaning the grassroots, in the coil and the base of the brush adhesive paste, according to the good benchmark line by far and near the paste, roll, and finally do seam joint inspection.
The laying of the rigid waterproof layer, should be completed in the first flexible waterproof layer after two days of construction, mainly in high fatty acid waterproofing agent, cement mortar, sand, fine aggregate, fiber as basic material, waterproof layer thickness is 20-30 mm.Install the partition batten according to the specification and set the grid to 4000 millimeters by 4000 millimeters. Then sprinkle water to make the base surface moist, but no water.According to the distance away from high to low, the order of the mortar prepared or fine stone concrete by lattice construction, with a lattice a complete, smooth compaction.After the initial setting, remove the partition bar, press and trim the partition joint.
Laying flexible waterproof layer, choose coating or coil can. The construction conditions require that the moisture content of the base surface is not greater than 9%, so it is suitable for construction in the summer after 5 days of hot weather. After completion, water storage experiments should be carried out.As a waterproof coating, coated cloth two for example: clean up the grassroots level, full of paint, dry film, laying a layer of glass fiber cloth reinforced matrix materials, and in the exhibition has fixed full brush a layer of paint on the surface, drying after construction paint. The overall thickness of waterproof coating should be more than 3 millimeters.
