Waterproof membrane thickness in Point Cook wet areas
A membrane can look finished and still be too thin.
In short: Bare and starved was the inspector's phrase, and it is the right one.
What starved means
The coating has been applied too thinly to reach the thickness the product requires.
Why it looks fine
Colour and coverage read as complete to the eye. Thickness does not.
What we recorded
A membrane bare and starved across many sections of a Point Cook wet area.
What happens next
Tiled over, it fails silently, and reaching it again means removing the tiling and often the lining.
When to catch it
After the membrane and before the tiler. That window is the whole opportunity.
