Product Description

Waterproof material coating painting for building

The product is made of special cement and multiple active chemicals. The permanent waterproof, moisture-proof applies to all cement mortar and concrete surface. At the same time, but also can improve the strength of concrete. Significantly enhance the erosion resistance of harmful chemical substances, brine and circulation of seawater erosion. Have a good protective of diatomite structure.

Technical principles:

The active chemical substance in cement-based permeable crystallization type waterproof coating which generate crystals in water insoluble hydration products inside the concrete pores. Clog the concrete pores; improve compactness and impermeability of concrete. If no water, the active chemical stays stationary state. When touch water, it will generate a new crystalline to seep into the deep of concrete. So the processed construction of concrete will produce new subtle crack by the reason of vibration and others. Once the water infiltration, it will bring new crystalline to block the water. This self repairing ability makes the waterproof function of concrete construction more durable and adaptive.

The anticorrosive type on the base of normal type, increase the resistance of waterproof layer. Reduce the porosity and change the internal microscopic holes construction. Improve the impermeability, lower the electric flux and prevent the penetration of chloride ions. Have a good resistance function of seawater and sulfate corrosion.

Product features:

1. Non-toxic, tasteless, pollution-free, approved for drinking water areas

2. After mixing with water, brush, spray, and wipe on the surface of mortar or concrete, also can be sprinkled with powder coated and pressed into the unset concrete surface. Water operations, the construction is simple and easy to operate, time saving.

3. Can be positive or the dorsal surface construction..and concrete form a complete unit. the lasting service life as the same with institutional body

4. Can withstand erosion of groundwater, seawater, chloride ion, carbon acid compound, oxides, sulfates, nitrates and most chemical erosion, play a role in the protection of concrete and reinforcement effect.

5. Enhance concrete compressive strength, With concrete, brick, mortar and stone materials are 100% compatible

6. Can maintain mortar or concrete matrix’s breath and permeability. Do not form water vapor accumulation inside the concrete to keep dry

7. Make structural micro cracks (≤ 0.2mm) self-healing, so that a substantial increase in structural durability

8. Even if the coating surface broken, as the product forming a large number of acicular and fibrous crystal deep into the grassroots inside, the matrix still has good impermeability.

Scope of Application:

Products suitable to all new and old concrete and masonry buildings for waterproof, moisture and protective. For example:

1. The basement, Metro, tunnel, culvert, ditch, sewer and other concrete structures in underground engineering.

2. Kitchen, bathroom, balcony, buildings with water facades, all kinds of pools.

3. Seawater, water conservancy and other concrete structures are particularly suitable for offshore structures waterproof, moisture and corrosion treatment

Note of uses:

Primary treatment		The concrete base should be clean, dust, dirt, gravel and dirt should be cleaned. Fully wet surface before the construction (available brush water brush on the base plane). But do not have clear water. Leakage should be blocked, honeycomb surface should be polished.
Mixture		Accurate weighing water and material. Mechanical stirring for 5 minutes and then stop for 3 minutes, then stir for 3 minutes before use, the slurry should be finished within 1 hour.
Construction	Methods	Scratch	Brush coating	Dry shake
	Coating thickness	1.0-1.5mm	0.8-1.2mm	0.8-1.0mm
	Unit dosage	1.2-1.8kg/m²	1.0-1.2 kg/m²	1.0-1.2 kg/m²
	Ratio of water	0.25~0.30: 1	0.35~0.40: 1	-
	requirement	Scratch one to two times	Brush coating two to three times	Spreading evenly
Precautions		The first curing before brushing second times(by hand touch without leaving sticky fingerprints as curing, if the last time the surface is drying whitish, you need to wet and then brushing again)Dry powder material in the not yet fully solidified concrete surface, using wood trowel immediately, Polishing powder is pressed into the concrete internal pressure light processing. Polishing machine takes the powder pressed into the concrete to conduct calendering process.
Conservation methods		Conservation methods: Depending on the construction environment. It can be: watering, cover the wet material, coating curing liquid, etc. The coating will not be damaged when sprinkling water conservation.The conservation will not less than 72 hours. Ensure the conservation so as to avoid powder coating or chapped.

Notice:

1. The temperature of construction should be at 5°C~35°C. Please do not construct in the negative temperature, scorching sun or under the rainfall.

2. After coating curing, should prevent sharp pierced coating. If damaged, should be repaired in due time. The ground and the roof of the flat need add cement or mortar protective layer.

3. Plastic bucket sealed packaging. Various packages of per barrel net weight of 5kg,10kg,25kg and so on. Sealed storage in dry environment to prevent damp. One year warranty.
