Overview Usage Product Specifications Handling Precautions

TRUBUILD WPC 666 (Waterproofing compound) is a single component elastomeric Acrylic based exterior protective coating to be applied over exterior surface of walls to prevent entry of water and moisture from the surface.

  • Can be applied as coating on External facades or Masonry wall
  • Can be applied on corrugated sheet, stone walls, asbestos, sloppy roofs etc.
  • Acrylic emulsion with water proofing applications.
  • Elastomeric membrane coating with UV resistance property
  • High elongation properties than paints
  • Upon drying forms, a thick, seamless, durable coating thus offering ultimate water proofing
  • Maximum 30% water can be added as a primer coat in Trubuild WPC which reduces the consumption of material further and seals the pores
How to use
How to use
  • Remove the loose materials, oil, dirt, debris from the substrate. Fill all the existing cracks up to 5 mm by making “V” groove and then filling it with crack filler paste (CFP 425). For cracks larger than 5mm use Polymer modified mortar making with WPL 333. Before application of WPC 666 on the substrate, it is to be ensured that the surface should be in Saturated Dry Condition. For Filling the pores on the surface Mix the WPC 666 with water as specified, then apply it as a primer coat. The coverage of primer coat will be approx. 80-90 sq ft per kg depending upon the substrate condition. After drying of Primer coat apply 1st coat of WPC 666 horizontally without any dilution. Allow the first coat to dry for min. 5-6 hours. then apply 2nd coat vertically without dilution.

NOTE: Please check the compatibility before applying on the substrate apart from masonry or concrete. Also, before doing any ponding test the coating should be air cured for min. 7 days. In case of excess moisture in substrate, there is chance of blister formation in coating. It is always advisable to check coverage on small surface area on site, before working on larger area.
