Please look for the "Zhu Long" trademark! Beware of counterfeiting!
"Zhu Long" ZL205? Type A polymer waterproof mortar additive (modifier) consists of imported polymer rubber powder, anti-crack fiber, polyacrylate and other polymer materials and other fillers. The modified polymer cement waterproof mortar is mixed with cement mortar to make high-performance polymer cement waterproof mortar, which is used in building waterproof and crack-resistant engineering and tile bonding. It has many functions such as crack resistance, impermeability, waterproof, wear resistance and corrosion resistance. , blocking the pores left by mortar hardening and water evaporation, so that mortar does not produce shrinkage cracks, reducing water absorption, and achieving the purposes of waterproof, impermeability and crack resistance. It is a new generation of waterproof materials for environmentally friendly buildings.
It solves the problem that polymer cement waterproof mortar can only be made a few millimeters thin due to high cost. The square cost of Zhu Long's thickness of 205 and 20 millimeters is only about 6 yuan higher than that of ordinary cement mortar! Polymer cement waterproof mortar can be completely used to level the plastered wall surface, improve the engineering quality and reduce the material cost, construction link and labor cost! It is of great significance to improve economic, social and ecological benefits; It is the preferred waterproof material for internal and external walls.
Using Zhu Long 205, the cost per ton of polymer cement waterproof mortar can be controlled within 500 yuan, which is the national standard!
