Hi,
After lifting the newly laid laminate in one of the bedrooms of my 1950s bungalow, noticed very damp/wet tiles underneath (which were bone dry a year ago when renovating) - see photos 1 & 2. I have painted layers of Wickes liquid DPM over the left over bitumen adhesive that was under the tiles hoping that this would stop the damp - see photo 3.
However, I laid the new underlay a couple of weeks ago but never got round to relaying the laminate and noticed the musty smell was back. It now looks like mold growing on top of the liquid DPM under the underlay and feels wet to touch! Not sure where to go from here now as nothing will stick to this stuff other than a 50mm layer of cement apparently which i'm guessing will just have the same problem? Could I lay a physical membrane over it and use self leveller over that or would it just lift?
Any advice would be much appreciated as my 2 year old is currently sleeping in our room, my wife is getting impatient and I'm slowly declining into despair!!
Thanks,
Phil
