I have an uneven concrete floor inside. I need to put down a damp proof membrane and self levelling compound on top of that. My questions are:
- Is there any reason to use a roll of DPM vs a liquid one or vice versa?
- Do I need to apply any sort of primer before putting down the SLC on top of the DPM?
- How thick does my layer of SLC need to be? I've seen various people quote up to 65mm! I really don't want to lose that much height.
If it makes a difference, vinyl will be stuck down over the SLC.
Thanks in advance
