Good Hydrophobicity cement waterproofing additive basecoat plaster

Waterproofing basecoat plaster is based on silica to add organic and inorganic gel material, so that they can proceed cross-linked reaction. Producing the trinity of combining good hydrophobicity,anti-permeability and cohesiveness rigid waterproofing material.

Product introduction

1. Construction is simple.
2. Unique penetrating function.
3. It is environmental product, no-toxic, no smell, non-radiation.
4. Has good two-way cohesiveness. Install tile, brick and stone directly onto membrane.
5. Have a long operation time and a short solidify time that saves time for other working procedure.
6. Good anti-aging ability and good weather resistance to protects concrete & reinforce cement from corrosion.

Scope of application

1. Indoor and outdoor plane and elevation of concrete structure, bottom surface cementing, brick wall, light brick and other institutions.
2. Be suitable for basement, parking place, swimming pool, water pool, kitchen, bathroom, and balcony and so on.
3. Waterproof for factory buildings, floors, underground parking and other stable structure parts.

Treatment of base plane

Base plane must be firm, smooth, and free of dust, grease, release agents, batik materials and so on.
All the small gaps and trachoma can be filled by paste which is mixed with powder and a little amount of water.
The exterior and internal angle should be fillet.
Leakage phenomena should be disposed firstly, and then start further waterproofing.
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 saved.

Construction technology

Mix 25kg powders with 7-8kg water for brushing; mix 25kg powders with 6-7kg water for smearing and pressing.
Firstly pour water into one container, and add slowly powder depending on the proportion, stirring until no code and even paste. Stewing for 5 minutes then stir 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 the first layer has been dry for a long time, 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 be prevent human trampling. When it is hot and dry, increase water curing in order to improve cohesion strength and waterproof effects.
 

Attentions

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 oC to 40 oC , cannot be done under 0 oC or rain.
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.
Any pipe surroundings, nodes and interface, expansion joints, structural joints, etc. of various base material, which have potential micro-vibration and movement, suggest to use YUNYAN flexible water proofing.
