WEATHERTUFF WP is a most effective and proven polymeric waterproofing solution.


  • Roof slabs – flat or sloping, chajjas, folded plate roofs, vaulted roofs, domes etc.
  • Flooring, external walls.
  • Sunk portion of bathrooms, toilets, balconies, etc.
  • Overhead or underground water tanks and other large reservoirs.
  • Mortars for filling joints of C. I. or any other drainage pipes.
  • As an admixture for providing waterproof plaster to external walls especially in high rise buildings.
  • As waterproof additive to any cement based paints used as a finishing coat.


  • Can be easily mixed with cement forming an impermeable co-matrix film.
  • High flexural strength and extraordinary adhesion of polymer reinforces the high compressive strength property of cementitious matrix.
  • Alkaline and compatible with concrete.
  • Does not facilitate carbonation.
  • Can be applied in moist conditions e.g: exteriors, terraces and chajjas in wet spells of monsoon, underground and/ or overhead water tanks almost immediately after emptying.
  • Can be mixed with any cement based paint and can thus have any desired colour shade.
  • Can be used as a base –waterproofing coat. After curing, it can receive Sunext–



  • Approximately 50 –55 ft2/ Kg. of WEATHERTUFF WP per coat on plain surfaces. May vary depending on the nature of the surface.



  • Preparation of the surface to be waterproofed is very important
  • Any significant deficiency in the civil work such as loose or hollow concrete/plaster, exposed reinforcement steel etc. should be first attended.
  • Required curing should be done as per the usual norms
  • Cracks other than hairline should be suitably widened, freed from loose particles and then filled with a mortar consisting of WETHAERTUFF EP ( Refer relevant product data sheet)
  • Scrub and clean the surface to free it from any bitumen, oil, grease, loose flakes or particles.
  • Moisten the surface with water jet one day prior to commencement of work.
  • Prepare a slurry of 1 part WEATHERTUFF WP and 1.25 parts fresh white or grey
    cement by weight.
  • Mixing is best done using a low–speed stirrer but continuous hand-mixing to a
    lump-free consistency is also adequate. Keep the mix continuously stirred.
  • Apply the slurry by brush to the damp surface.
  • Apply two more coats of similar slurry at 24 hrs intervals.
  • Allow to set for 48 hours.
  • Cure the coating for 7 days by sprinkling water three times a day on the vertical
    surface (external walls) and by moist gunny bags on the horizontal surface (terraces).
  • For best results it is necessary to sandwich the cured coating of WEATHERTUFF WP with a screed layer.



  • WEATHERTUFF WP should be stored preferably in shade and in original containers. It has a shelf life of 12 months when stored in cool , dry place.



  • Health hazards: No particular hazard known. If the product spills on to the skin and dries
    up, some irritation may occur.



  • Skin contact: Immediately wash thoroughly with soap and water.
  • Inhalation: Remove to open air.
  • Seek medical attention.
  • Contact with eyes: Immediately wash under running water with eyelids open for at least 15 minutes. Seek medical attention.
  • Ingestion: Rinse mouth thoroughly and drink plenty of water. Seek medical attention.



  • Environment Care: Clean small spillages immediately with water. Contain large spillages with suitable absorbent materials. Dispose the waste water/absorbent material
    in accordance with local regulations.
