I have an uneven concrete floor in the downstairs hallway. By this I mean the whole floor is on a horizontal slant (the left is lower than the right). From what I understand some self levelling compound will fix this right up. To finish the floor I want to lay down some vinyl flooring (not vinyl tiles), and from my research it seems a damp proof membrane is advisable because of the concrete. Finally, the vinyl supplier recommends a screed to be laid before the vinyl. My question is: in what order should these be laid (if indeed they are all needed)? At first glance I would guess: self levelling compound, DPM, screed, vinyl. But I've also seen there is such a thing as self levelling screed. In this case would DPM, self levelling screed, vinyl suffice? Also what kind of thickness would I be adding in each case? Thanks in advance
Hi notgreatatdiy, I mix the two terms self levelling screed and self levelling compound - they are the same thing. Your requirement to incorporate a DPM on your existing floor will be difficult. You could paint the existing floor with a liquid DPM sand blind it and then use self levelling compound to give a finished level surface. You will have to accept that this will be like a layer of toffee and may separate from the DPM. The compound you choose will specify min/max thicknesses. Regards S
