First of all 

Use Common Sense!

The ONLY way to really go wrong with using Liquid Rubber Waterproofing products is when the steps are not carried out properly, short cuts are taken and/or lack of care when preparing and applying.

  • Many of our DIYers use Liquid Rubber for waterproofing projects such as: caravans & camper roofs & undercarriages, boat decks & hulls, aquariums, fish ponds, planter boxes, balcony refurbishment, leaking roof/gutters, retaining walls etc. 
  • Waterproofing with Liquid Rubber can be easily undertaken by the home handy person or tradie with minimal previous knowledge of how to waterproof. 
  • Just as a very quick note - whenever we have come across Liquid Rubber not bonding to a surface - it is invariably due to a "dirty" surface that was not cleaned properly.
  • If you know you have a previous old membrane on the surface that you want to make waterproof or you know previous products have been used or a surface has mold, dirt, lichen etc. - PLEASE CLEAN THOROUGHLY.
  • Do It ONCE & Do It Right.
  • NB: Large projects & complex surfaces should be applied by Australian Certified Liquid Rubber Applicators.
