Features:

1, Inorganic waterproof mortar. When there are water and active chemical substance permeating into the concrete pores, it produces a chemical action with the free radical and the unhydrated cement particle to form dendritic crystal which is not soluble in water.

2, This crystal combines with the concrete to block out water and other liquid. When there is no water, the active substance is in a dormant state.

3, When the surface and interior of the concrete appears micro cracks , the active substance can hydrate again and produce a new hydrated crystal to block out water. So K11 Cementitious Capillary Crystalline Waterproof Slurry can make the concrete water-resistant.

4, Suitable for waterproofing of basement, underground parking , swimming pool, sewage treatment pool, subway, tunnel, reservoir dam, harbor and other important projects.

Application:

1, Can waterproof both on the positive and back sides.

2, Concrete structures waterproofing should take relevant measures when in the open-air environment.

3, For the structure with alternate-deformation cracks, using flexible material to fill the downing cracks and deformation cracks, instead of PB-K11 Cementitious Capillary Crystalline Waterproof Slurry.

4, Do not operate under 4℃.

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,If the surface is dry,  moist the surface with clean water till there is no clear water before operation.

Operation Process:

1, Base surface:

Check the concrete surface whether it has any defect, or steel, organic, oil painting, and other bonding materials. For the crack, using a steel brush to roughening mainly.

e.g. For the crack above 0.4mm, requiring a 15×20mm U-groove. Use steel brush, chisel or water cannon to roughening the concrete surface, which can never leave any suspended materials after cleaned.

2, Brushing:

(1) Using semi-rigid nylon brush to brush.

(2) Brush back and forth and pay attention to the cave and convex place, and ensure the surface is flat with a same thickness.

(3) When operate on the plane or stage, brush the material evenly, especially for the front and backlight sides, never make thick deposition to forbid cracks in the thick place.

(4) For the crack over 0.4mm, requiring slot first, then moist it. And brush the concentrating slurry, then strengthen it with semi-dry material 1.5h later, and continue brushing the material.

(5) It requires to brush two layers, after the first layer dried (about 1~2h), brush the second layer. If the first layer dries too quickly, moist it before the second time.

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

c, After the first layer dried completely, brush the second layer about 2~4 hours later, the direction of the two layers should be vertical.

Normal Amount: 

1.2~1.4kg/㎡                   

Thickness: 1.0~1.2mm                   

Ratio: powder: additive: water= 25: 3:(5~7).

Cautions:

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

2, To gain a better effect, do not operate under 5℃ or in 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, Our technical department can provide operation scheme in special situation.

Store Method:

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

Packing:

25kg/bag powder + 3kg emulsion (active chemical additives)
