1. Good flexibility can cover minuteness crack caused by various reasons.
2. Excellent adherence with surface of concrete and bricks.
3. Easily used by trowel and spatula, no leaking while uprightness.
4. Can be applied to wet surface or freshly placed concrete.
5. Good weatherability and UV resistance.
6. Can be applied to both the external and internal walls, bearing high water pressure whenever positive or negative.
7. Environmental product without toxin, smelling, pollution, radioactivity.

1. Base materials waterproofing of concrete, brickwork, pre-cast concrete and floating brick, etc.
2. Waterproofing of building wall, floor and roof.
3. Waterproofing projects of underground car park, tunnel, drainage and water supply pipes,
swimming pool and drinking water pool, etc.
4. Other waterproofing projects.
Substrate preparation
1. The substrate should be flat, no oil slicks, release agent, dust and other loosen material which
influence coherence.
2. The concrete fallen off or loosening have to be removed, and the larger holes, cracks should be
repaired first.
3. It’s better for the inside corner and outside corner to be arc angle.
4. The surface of freshly placed concrete should be dry completely prior to commencement of
construction.
5. It’s better to deal with substrate by mix (emulsion : water = 1:1) before brush, especially for the
loose one.
Wet basal surface
To wet basal surface thoroughly, operation can be processed after water is completely infiltrated
into concrete and without left.
Mixing
First, dump emulsion into the clean container, then start to use electric blenders;Put dry powder
slowly in appropriate proportion(powder components : emulsion = 1 : 0.6),blending completely to
equality dope without agglomeration(about 4-5min) .It must be used up in the recommended time
(about 1 hour).
Application
Spread slurry on the basal surface which treated well by coating knife or spatula. According to the
requirement brush at least 2 layers (total thickness of 1.5-2.0mm). Until the first layer slightly dry
(touch free) can make the second which depending on the substrate density, temperature and
humidity in 1- 3 hours.

Tips of Usage
Polymer Modified Cementitious Waterproof Coating requires 5 ~ 45°C and relative humidity less
than 85% of the ventilation condition. If the temperature is below 5°C or rainy day, it can’t be applied
There will be discrepancy of its color caused by the density and humility of working surface. Be
attention to prevent from rain, strong sunlight or froze first two days. Tools and equipments should
be cleaned after working in time.
