K11 Flexible Waterproofing Slurry

  YY-922 (type II)




K11 Flexible Waterproofing Slurry is a two-component, a thin, load-bearing waterproofing mortar based on cementitious binders, special additives and synthetic polymers. It's a special formula which developed in YUNYAN's own research laboratories.



1. Waterbased and environmental product, notoxic, no smell, no radiation, is suitable for drinking water tanks, swimming

    and pasted by stone, tile and so on.


3. Can be used to waterproofing construct of wet base plane, plane and elevation, teehead buttress and back surface.


4. With “breathing” function, waterproof but breathable.


5. Can withstand the non-structural vibration of the building and slight cracks produced by normal displacement.


6. The waterproof layer doesn’t need the protective layer; can start next process after cures completely (usually 24 hours).




1. Water proofing for indoor and outdoor concrete structures, precast, brick and other lightweight substrate.

3. The exterior and internal angle should be fillet.


4. Leakage phenomena should be disposed firstly, and then start further waterproofing.


5. Base plane should be prewet, and be constructed after no clear water. That the construction could be faster, smoother;

    construction efficiency could be improved, material costs could be saved.




1. Pour the powder into the additive in proportion, stir until get even and no end groups’ paste. After standing for 5 

    minutes could get the better stirring effect.


2. According to construction requirements determine the number of times, generally impervious and moisture paint 1-    2 times, water proofing paint 2-3 times. It is better to paint by crossways. 


3. After the first pass completion of the construction, should wait it is almost dry, or nonstick hand, and then construct a 

   second time, usually at intervals of 2 hours.


4. If it takes too long to dry the first layer, the construction should start after wetting the base plane and without clear water.




1.Well-mixed sizing agent should be used within 2 hours, if it comes dry don’t add water and reuse.
