Basement High Flexible K11 Slurry Waterproof Coating 1.5mm

 

 

Features:

 

1, Good flexibility, can effectively inhibit the expansion of the underlying micro-cracks.

2, Can be used on the wet surface of the basic construction.

3, Strong bond with the substrate, the active ingredient in the slurry can penetrate the pores and micro-cracks in the cement-based surface, and produce a chemical reaction with the substrate to form a crystal-integrated waterproof layer.

4, Can follow up directly after the slurry dryied without mortar layer.

5, Highly water-resistant pressure and water permeability, can be the waterproof both for the positive and back sides.

6, Non-toxic, harmless, and environmental-friendly product.

7, Excellent aging resistance and good corrosion resistance.

 

 

Application:

 

1,The waterproof for indoor and outdoor concrete structure, precast concrete structure, brick wall and so on.

2, Underground car parks, tunnels, drainage and water supply pipes, walls, floor, roof floor, swimming pool, kitchen and other waterproofing projects.

3, The waterproof for the place that may appear slight vibration, movement, structural cracks and pipes, or the after pouring area.

Note:

      Type I applies to non-permanent flooding and large displacement grassroots area.

      Type II applies to long-term flooding and small displacement grassroots area.

 

 

Surface Treatment:

 

1, The surface should be stable, clean, smooth, no dust, no oil, no shedding, and other detrital materials.

2, The obvious pores and holes must be silted up with the cement mortar, the sharp edges should be wiped out.

3, Moist the surface with clean water till there is no clear water before operation.

 

 

Operation Process:

 

1, Mixing ratio: type I:25kg powder+18kg additive

             type II:25kg powder+13kg additive

2, Pouring the additives into the container, then slowly pour the powder and stir them into a uniform, no-powder and no-deposit paste.

3, During the operation, keep intermittent stir to avoid precipitation

4,Using brush or roller to brush on the surface of the basic construction directly, do not leak anywhere. First layer is for dampproofing, second layer is for waterproofing.

 

 

Tips:

 

a, Dealing with the surface according to the requirements, cooling the surface with water slightly to reduce the temperature if under the heat and sun exposure.

b, Using brush to brush the mixed slurry on the surface evenly and make sure it no flaws and vulnerabilities.

c, When finishing the first layer of brushing, brushing the second layer about 2~4 hours later, the direction should be vertical for the two layers.

Normal Amount:

 

Type I:

1, For moisture proofing, the first-brushing thickness is about 0.6~0.8mm and is about 43~55㎡/flat.

2, For water proofing, the second-brushing thickness is about 1.2~1.5mm and is about 20~25㎡/flat.

 

Type II:

1, For moisture proofing, the first-brushing thickness is about 0.6~0.8mm and is about 25~35㎡/flat.

2, For water proofing, the second-brushing thickness is about 1.2~1.5mm and is about 20~25㎡/flat.

(Note: all the above amounts are based on the smooth degree of the surface)

 

 

Cautions:

 

1, Do other covers after the waterproof layer totally dry.

2, For a better effect, do not operate under 5℃ or particularly damp and unventilated situation.

3, Never mix the dry slurry with water for second use.

4, Processing the nodes according to relevant requirements, adding a fiber layer is better.

5, Under special situation, our company can provide operation scheme by our technical department.

 

 

Store Method:

 

Store in cool and dry place, unopened product can be saved for one year.
