1. Has unique penetrating function.
2. The waterproof layer doesn’t need the protective layer.
3. It is environmental product, no-toxic, no smell, non radiation.
4. Cement-based product has anti-aging, good weather resistance
5. Construction is simple, brush directly, greatly improves
6. Has good two-way cohesiveness. Waterproof layer can be directly
plastered and pasted.
Scope of application
1, Indoor and outdoor plane and elevation of concrete structure,
bottom surface cementing, brick wall, light brick and other
2, Be suitable for basement, parking place, swimming pool, water
pool, kitchen, bathroom, and balcony and so on.
3, It can be used for wall repairing, tile fracture, and
large-scale renovation waterproof.
Treatment of base plane
■Base plane must be firm, smooth, and free of dust, oil, release
agents, batik materials and so on.
■All the small gaps and hole can be filled which is mixed with
powder with a small amount of water.
■The exterior and internal angle should be roung.
■Leakage phenomena should be disposed firstly, and then start
■Base plane should be pre-wet, and be constructed after no clear
water. That the construction could be faster, smoother;
construction efficiency could be improved, material costs could be
■Mix 25kg powders with 9 latex for brushing; Firstly put latex into
one container, and add slowly powder, and then stir completely,
standing for 5 minutes then remix again could get better effect.
■Brush using crossways more than 2 directions by roller or brush;
depending on the standards of waterproof, base material and so on.
The second time of construction should be done after 2 hours of the
first one, it is the best time when the first layer not completely
dry, or non-stick hand.
■If it takes too long to dry the first layer, the construction
should start after wetting the base plane and without clear water.
■Keep stirring intermittently to prevent precipitation.
Within 24 hours of completion of the construction, should to
prevent human trampling. When it is hot and dry, increase water
curing in order to improve cohesion strength and waterproof
■Well-mixed sizing agent should be used within 2 hours, if it comes
dry don’t add water and reuse.
■Construction should be done from 5 to 40℃, cannot be done under 0
■Provide ventilation installation when construct in poorly
ventilated or enclosed environment.
■The construction should start after the base plane is wet and
without clear water, which can greatly improve waterproof effect;
if it takes long time between 2 times constructions that should
start after wet.
Keep in cold and dry place, unopened powder is valid for 1 year,
additives is valid for 12 months.
