  • AQUA FLEX W9 Waterproofing is supplied in precisely proportioned units ready for mixing,
  1. Shake the liquid component. Transfer the entire quantity of liquid part A to a clean vessel. Aqua flex waterproofing shall be mixed with a low speed stirrer ( < 500 RPM).
  2. Start adding powder part B to liquid part A in to a vessel. Mix till smooth & homogeneous slurry without any lumps. Mix thoroughly for at least 3-4 minutes to required consistency.
  1. The surface must be dry & dampened (with no standing water).
  2. AQUA FLEX W9 Waterproofing is applied on the positive side of the substrate.
  3. Start applying the first coat of slurry by a stiff brush of 120-150 mm or broom, roller or flat trowel maintaining thickness of 1 mm. if required embed with a fibre glass mesh. When the material is sticky use a trowel to work the material up and trough the mesh until it is completely embedded.
  4. Allow the 1st coat to dry for 4-6 hours.
  1. Start applying the 2nd coat. The two coat thickness should be minimum 2 mm.
  2. 2nd coat should be always applied in opposite direction to the 1st coat.
  3. If the areas subjected to heavy hydrostatic pressure apply another coat.
  4. The product applied area should be protected from direct sunlight & to be damp cured by covering with damp hessian. After that it should be protect by overlapping of screed.
Precaution & Limitations:
  1. Do not add water at site.
  2. Mix the entire material at once.
  3. Do not flood or over expose the treated surface to water until it is completely cures.
  4. When applying the material, the surface temperature should not be less than 10°C or more than 45°C.
  5. Allow 14 days curing before submersion.
