Extension of polymer cement mortar waterproofing agent polymer cement mortar waterproofing agent is a combination of polymer composite materials made of powder. The main ingredients are: Germany imported powder, methyl cellulose, Durafiber, polyacrylates and other polymer composite materials. The case of high-performance polymer modifiers, mixed with ordinary cement mortar mixed use, fully meet the crack resistance, impermeability, waterproof, moisture, frost, abrasion resistant, corrosion-resistant and other functions, is a new generation of environmentally friendly products, complete in line with national standards. The major products of polymer cement mortar waterproofing agent is a composite material made from a polymer. With anti-infiltration, water reduction, enhancement. This product was added to the mortar mixing cement particles can accelerate the hydration and dispersion, significantly reduce water consumption, closed after mortar hardening capillary pores and voids left by the evaporation of water, so that no mortar dry shrinkage crack, lower water absorption, reach waterproof prevent cracking and leakage, and enhance purposes. The product range for high-rise, multi-storey, high-rise and other buildings in the outer walls, kitchen, bathroom, balcony, level, window surrounding, wall pipes, floors, ports, docks, roads, bridges, ponds, water towers and civil and other desired mortar waterproofing. Usage and dosage (1) content accounts for 3.5 to 5% of cement consumption, by mechanical agitation, a little stop 10 minutes after application; (2) primary requirement: grass surface without oil, dust; (3) the use of Portland cement : ordinary portland cement or slag cement may, numerals not less than 32.5Mpa packaging, storage (1) of the polymer mortar waterproofing agent for the plastic woven bag, net weight 25 kg; (2) Powder should be stored in dry flat place, to prevent the tide variations or break; (3) Duration: one year (4) Implementation of standards: JC984-2005
