Hi!
We're owner-builders doing as much DIY of our reno as possible. Our home has been restumped and 19mm yellow-tongue placed through most. Above this will be 19mm hardwood flooring, except for the kitchen where the travertine is 12mm thick. To both make-up the height difference and add waterproofing/resistance we're wondering if:
1. We can adhere thin (e.g. 4-6mm thick) cement sheeting to the yellow-tongue in the kitchen area (if yes, which product is best to use to adhere the two)
2. If we need to also waterproof the kitchen area (which product again is recommended)
Thanks heaps!
