Waterproofing Bathrooms and Wet Areas

Waterproofing Bathrooms, Laundry’s and kitchens are usually the wettest rooms in any house. Should these wet areas be not waterproofed correctly will cause structural damage to your building structure and even attract white ants which love damp areas. The data tells us that the average age of a bathroom is approximately 10 years before it’s renovated. In fact this makes it one of the most commonly renovated rooms in the house. Fortunately or unfortunately Australian Standards AS 3740 apply to any waterproofing used. The unfortunate part is that many standards represent only the minimum requirement for the treatment.
The following information is designed for practical advice to when you can use:

2.Traditional Waterproofing Bathrooms and Wet Areas

Liquid sealants such as SealTuff – PU- WET AREAS are normally applied in a similar fashion to cementitious system or a 2 coat paint. A primer may be applied to the area first, then the first coat of SealTuff is applied from left to right (horizontally). The second coat is then to finished using up and down strokes (i.e. vertically), this helps to make sure any small/pin holes missed in the first coat are completely sealed. Flexible sealants are used around the bathroom where the bath and vanity units meet the walls, to prevent water doesn’t get behind them and cause premature damage.

Note:

  • Waterproofing products may take a few days to dry or cure, usually this is just a day or 2, check with supplier to make sure, so that you get the correct waterproof seal  –
  • Also these waterproof membranes shouldn’t be disturbed at all while they’re curing so make sure that plumbing works are largely completed prior to the wet areas waterproofing.
  • Tiling should started only after the waterproofing has completely cured
