Panel with chloroprene latex cement grout epoxy membrane: 1, clear: at the grass-roots level will loose concrete cushion layer, such as epoxy grout clean, prominent bulge out. 2, brush the cement slurry, mixing ratio of cement: latex = 1:0. 05 ( Weight ratio) , add right amount water to mix a gruel, PuTan on the ground, with a broom and brush it again. 3, waterproof with the epoxy grout: with the mixing ratio of cement, yellow sand, latex, 2-0. 35 ( ( Weight ratio) 。 Mixed epoxy grout fell on the ground, with a bar feet, leveling wood float shunping, iron float pressure again, in epoxy grout draw close before final set pressure, thickness of 20 mm. 4, maintenance: after being ground have a certain strength, surface cover bag or sack often water wet, curing time, which shall be determined according to the temperature conditions for 7 days commonly, slag Portland cement should not be less than 14 days, the period shall not be subjected to hydrostatic pressure. Side walls with chloroprene latex cement grout waterproof layer: epoxy with waterproof epoxy grout have a certain strength, often water, keep wet metope, curing time, which shall be determined according to the temperature conditions for 7 days commonly, slag silicon aluminium salt cement should not be less than 14 days end, namely water clean all stained with paint and instrument.
