concrete sealer coating
1.Usage:1.8% of cement weight. That is, one bag of cement (50 kg) equipped with a bag of this product (0.9 kg). By mechanical mixing, mix this paste after cement mortar mixed evenly.
2.using artificial mixing or mixing cement paste, dilute this paste with 28-30 times water. best diluted with hot water.
3.waterproof work should be at least 2-3 mm paste layer and 10-20 mm mortar layer, Internal angles has to be arc. Moist curing time should be more than 14days.
4.This should be sealed in shading department above 0 °C.
