Hi All,
I am new to the forum so I apologise for my mistakes.
I have lifted a laminate flooring from a hallway floor to expose loose tiles adhered with a thin layer of what looks to be bitumen.
After reading many people's posts I have scraped as much as I can off. Beneath the screed is a plastic DPM which seems broken at the edges.
I was thinking of Laying a liquid DPM over the existing screed, then priming with SBR Laying underfloor heating insulation boards on rsf adhesive, laying mat, self levelling, priming and then tiling.
Is this the correct procedure or should I prime onto the remaining bitumen and skip the DPM steps?
Thanks in advance.
Chris.
