Step by step instructions

  1. Wash/waterblast the entire surface.
  2. Wear protective gear (gumboots) and use a submersible pump to empty it and a wet and dry vacuum to suck the remaining water out and we then put a fan forced ventilator in to start the drying process. 
  3. Once dry, apply waterproof sealant by brush, roller or LRDIY spray machine to cracks, holes, corners, wall floor joints, pipe inlet/overflow, or over the top of applied seamtape. Apply the correct width geotextile at the same time onto the wet product over the hole, cracks, etc. and ensure you brush the air from underneath the applied geotextile and make sure there are no crinkles. Refer to the full video below.
  4. During this you can use rapid cure spray to instantly set the product incase of approaching rain or to speed the job up. Watch the rapid cure video to see how this is done.
  5. Apply a second coat to all the above areas and if so the 3rd coat , depending how thick you want it and how long you want it to last.
  6. Next step is very important, waterproof sealant must be cured, ventilation stays on 24hours, 10 days. Drying is key for water tanks.
