First, buy a professional, supporting strong products. According to the texture sheet, color, structure and use different objects, paint designs and technology are different slurry injection manufacturers, which requires product manufacturers to provide technical guidance and after-sales service for consumers. Regular manufacturers can provide a model for rich colors for consumers to choose the color card. Second, look at the product before buying paint presence trademarks and product brochures. Regular factory paint should trademark, manufacturer name, date, weight, and other important data on the drums mark. Three, depending on whether the product is recognized by the Government through the testing department of safety testing.

(2) due to thermal expansion and contraction caused by the cracks. (3) improper mixing ratio design, construction vibrators not dense, compacted, and received a bad light slurry injection early dehydration, improper post-curing, cracks due to shrinkage of cement produced. Depending crack repair area size. If the area is small, large cracks, apply a flexible waterproof seal material filling the cracks, and then do the waterproofing. If cracks larger, more dispersed. First with a waterproof sealant filling cracks with a suitable waterproof material to redo it again. B, roof leaks reasons: (1) connecting the various components and sub-sewn seam in the lattice packing sealing material is not to clean the joints, filling untrue. Maintenance tools to connect seam dividing joint clean, dry sides of the gap with a blowtorch, with the passing of the sealing material re-filling. (2) parapet gutter, fell into the mouth, stairwells, chimneys and various parts of prominent seams or seam roof construction, due to lax packing cement mortar joints, cracks and leaks form. Maintenance: The tool will parapet gutter, the water ports, seams stairways, chimneys and roofs of various prominent tamping, these parts do add a layer of waterproof layer. C, waterproof layer from the shell sand reasons: poor quality concrete waterproofing layer, no compaction and curing received bad. Rigid roof sun and rain, over the concrete surface will occur carbonization. Maintenance: Using tools from the shell, part sand smashing, smashing real, do it again with a waterproof mortar waterproof layer and compacted close attention to the light. Can be green or doing on the roof insulation layer protection.
