PU Waterproof Material

Polyurethane (PU) waterproof materials have three categories, which are the primer, top-coat and mid-coat. The polyurethane primer has superior penetration and tensile strength, excellent elongation and adhesion. It is especially effective for sandy, weathered walls and floors. It is a moisture-curing adhesive;  PU top coating is acrylic resin with high weather fastness and adhesion strength. It's a non-yellowing resin coating and mainly used on exterior wall tiles for waterproofing; the polyurethane mid coats is for the coating of indoor, outdoor and vertical walls waterproofing engineering. It's a coating material with high ductility, high physical properties, high weather resistance, and easy construction.

Applicable for the surface waterproof of buildings, houses, factories, schools, roof gardens, etc.



  • Top coating: Clear waterproofing topcoat for exterior wall, topcoat for natural stone coating, PU, EPOXY and marking for court, also be used for R.C, polyurea, metal, wood, etc.
  • Mid coats: Indoor, outdoor and vertical walls waterproofing works of buildings, homes, factories, schools, roof gardens, bathrooms, water towers, and cement  buildings.
  • Primer: It has excellent result on the wall and land which is weathered and sanded.


    Top coating:
  1. acrylic resin
  2. Strong follow-up.
  3. Good weather resistance.
  4. Anti-yellowing resin, anti-ultraviolet radiation.
  5. Excellent wear resistance and water resistance.
  6. Excellent overlap after repeated painting.
  7. Protective paint for PU, polyurea, metal and wood.
  8. Scribe paint.
    Mid coats:
  1. Easy and fast installation.
  2. May use on uneven surfaces.
  3. Use on the edge of pipe, wall corner and vertical wall with convenient construction.
  4. Well weather resistant, tear resistant, and extensibility that will not crack or create a rough surface.
  5. Well elasticity and beautify the appearance.
  6. Securely adheres to cement without peeling off, it can also be used to fill cracks.
  1. Superior penetration and tensile strength.
  2. Excellent elongation and adhesion.
  3. Moisture hardening type adhesive.

Notice under installation

  1. Is the surface completely dried (Humidity below 8%)?
  2. Is there any sand, dust, dirty particles, hive, and grit, on the surface?
  3. Is the mixing ratio correct and even?
  4. Is the vertical thickness enough or not?
  5. Serious crack should be filled at first.
