3.  Can be used to waterproofing construct of wet base plane, plane and elevation, tee-head 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).


Scope of application

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

  3. 3.       The exterior and internal angle should be fillet.
  4. 4.       Leakage phenomena should be disposed firstly, and then start further waterproofing.
  5. 5.       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 saved.


Construction technology

  1. 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. 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.
