Cement Mortar Waterproofer Additive Basecoat Plaster Of Concrete
Structure For Basement
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
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
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
■ 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 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
■ 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.
