Description

Product Introduction
Cement-based capillary penetrate crystalline type  waterproof coating is a kind of powder materials which is composed of ordinary portland cement,selected quartz sand and many kinds of active chemical components. Water as the carrier,the active substances get into the concrete crack and turn into crystallize,permanently plug water seepage channel,and can be secondary activation crystallization.With foreign core master batch technology make its performance exceedingly good.

Features
1、Can withstand high hydraulic pressure long time,lasting effect in waterproof,anti-seepage
2、Simple operation,saving time and reduce the cost
3、Super penetration ability,unique ability to repair itself
4、Can withstand most of the chemical erosion,such as erosive ground water,sea water,chloride ion, carbon acid compounds,oxide,sulfate and nitrate,play a role of protecting concrete and preventing the reinforcement from corrosion 
5、100% compatibility with concrete,brick,cement mortar and stone materials can construct cement mortar,paste tile,etc.

Scope of Application 

1. All kinds of pool: swimming pool,sewage-farm flower bed,fountain,etc.
2. Waterproof, moisture proof,anti-permeability in subway,tunnel,garages,underground structure
3. Widely used in underground,ground,roof and wall of buildings for waterproof,moisture proof and anti-permeability in maintenance.
4. Non-toxic,approved can be used in the field of drinking water.

Construction Technique:
1.The basic level requirement: the concrete base surface should be wetting,no obvious water, impurities like floating dust,oil,grease,etc,not allowed to appear on the working surface, phenomenon like loose, peeling should not happened,grind over smooth surface to be rough to help bond and infiltrate the coating and base each other.Honeycomb,holes,larger crack and serious uneven place, should first fill leveling processing,crack parts must be slotted,then fill to level.
2.Confecting: water: cement 0.3:1,use clean water,stir well mechanically at low speed,use the mixed material up within 20 minutes,If over the time,and it become stiff,stir again strongly,but prohibit to add water again.
3.Construction: To coat by the methods of hand brush,scraper,trowel,etc.Strength evenly and its thickness is consistent,there shall be no accumulation,grinning phenomenon.( Note: filling-in tiny hole before coating the second time)
4.It is better to coat 2~3 times, dosage of the monolayer should be controlled around 0.4~0.6kg/㎡, conduct the second coat when the first one begins to initial set but still damp,intervals should not be longer than 24 hours
5.Recommended dosage: 1.0~1.2㎏/㎡
6.Curing and attention:spraying like mist water cure the coating when it is in half dry or begin to dry,2 or 3 times a day,spray 3 days,if moisture volatilize too fast in outdoor environment,spray more times or cover it. There is no need to cure below 10°C 

Storage: keep in dry and ventilated environment,guarantee period: 12 months

Package: 25 kg/barrel
