Waterproof Mortars

QualiCell cellulose ether products in Waterproof Mortars can effectively improve the crack resistance of the mortar, reduce the water absorption and dry shrinkage of the rigid waterproof mortar, so as to achieve the effect of waterproof and impermeability.

Cellulose ether for Waterproof Mortars

Waterproof mortar is also called cationic neoprene latex waterproof and anticorrosive material. Cationic neoprene latex is a kind of water-proof and anticorrosive system based on modified polymer molecules. By introducing imported epoxy resin modified latex and adding domestic neoprene latex, polyacrylate, synthetic rubber, various emulsifiers, modified latex and other high polymer latex. It is a polymer waterproof and anticorrosive material by adding base material, appropriate amount of chemical additives and fillers, and adding through plasticizing, mixing, calendering and other processes. Imported materials and domestic high-quality auxiliary materials are selected, and high-quality products produced in accordance with the highest level of national industry standards are recommended for the construction of national well-off housing. Long lifespan, convenient construction, long-term immersion in water, life span of more than 50 years.


Waterproof mortar has good weather resistance, durability, impermeability, compactness and extremely high adhesion, as well as a strong waterproof and anticorrosive effect. It can withstand the corrosion of soda ash production media, urea, ammonium nitrate, sea water, hydrochloric acid and acid-base salts. It is mixed with sand ordinary cement and special cement to make cement mortar, which is cast or sprayed with cement mortar, and is manually applied to form a strong waterproof and anticorrosive mortar layer on the concrete and surface. It is a rigid and tough waterproof and anticorrosive material. Mixing with cement and sand can modify the mortar, which can be used for the treatment of building walls and ground and the waterproof layer of underground engineering.

Waterproofing systems are divided into rigid sealing slurries and so called flexible sealing membranes according to EN14891.

In general, rigid sealing slurries are used to protect construction parts against moisture and water. Flexible waterproofing systems are based on polymer modified cementitious mortars. They are mainly used beneath tiles in wet areas like kitchens, bath rooms and balconies.

What are the advantages of waterproof mortar?
Waterproof mortar can be applied on the wet surface, which is difficult for domestic general solvent waterproof and anticorrosive materials. The construction can be carried out in mixed concrete. Because the object has an impact on the construction base surface, the adhesion of the coating to the concrete is increased. At the same time, the cationic neoprene latex material fills the pores and micro cracks in the mortar, so that the coating has Good impermeability. The cohesive force is 3 to 4 times higher than that of ordinary cement mortar, and the flexural strength is more than 3 times higher than that of ordinary cement mortar, so the mortar has better crack resistance. It can be waterproof, corrosion-proof and moisture-proof on the front, back, slope, and different sides. Strong bonding force, will not produce hollowing, crack resistance, water channeling and other phenomena.

Cationic neoprene latex can be used for waterproofing and anticorrosion, as well as for plugging and repairing. There is no leveling layer and protective layer, and it can be completed in one day. The construction period is short and the comprehensive cost is low. It can be constructed on a wet or dry base surface, but the base layer must not have running water or stagnant water. Cationic neoprene latex has the general properties of neoprene, excellent mechanical properties, resistance to sunlight, ozone and atmosphere, and seawater aging, resistance to oil esters, acids, alkalis and other chemical corrosion, heat resistance, non-prolonged burning, self-extinguishing, resistance Deformation, vibration resistance, abrasion resistance, good air tightness and water resistance, and high total adhesion. It is non-toxic and harmless, and can be used in the construction of drinking pools. The construction is safe and simple.
