Water Repellent


Trubuild WRP 777 (Water Repellent) is silane based non-flammable water soluble solution designed to incorporate water repellence to varied surface like sand stone, marble, concrete, exposed bricks and terracotta tiles. It is used for water proofing of most of the construction surfaces as it penetrates deeply in the surface and provides excellent water repellence without changing appearance/colour of substrate

Meets the requirement of IS: 12027: 1987.

  • As a sealer for sand stone, concrete & marble surfaces
  • Can be used on any porous substrate.
  • Brush able and easy to use.
  • Trubuild WRP 777 is breathable, penetrable and supplied in ready to use form.
  • Doesn’t stain as well as change appearance and colour of substrate
  • Cost effective
  • Anti-Fungal & Waterproof for porous stone, concrete, plasters etc.
  • Due to low viscosity penetration in substrate is very high
  • Use of Trubuild WRP 777 reduces efflorescence, improve resistance to effects of weathering and seals porous substrates against moisture.
How to use
How to use
  • Surface to be treated should be dry and free from all dirt, oil, debris and all other contamination which could prevent penetration.
  • Apply one coat of Trubuild WRP 777 by brush and left the same to dry for next 24 hrs.
  • In case of high porosity, two coats need to be applied. Apply second coat wet on wet to improve the penetration and performance and again left the same to dry for next 24 hrs.
