First I want to apologies for asking the same question that's been asked over 100 times in a hundred different ways with lots of different answers but I just want to be 100% sure before I proceed.
I live in an ex-local authority house, back in the day to stop the terraced houses burning down the ripped out the wooden floors from the kitchens and filled them with cement, but neglected to install a DPM (I don't know for sure that they didn't, I just think it's unlikely they did).
Today the floor has a 2cm thick covering of bitumen/asphalt. However through various building work that's gone on, a 3m square section has been damaged and cracked.
Generally the advice I've found has been "if it's in, like it or not, leave it alone."
I've read the post on how to install a surface DPM //www.diynot.com/forums/viewtopic.php?t=80131&start=0
I've looked at the F-Ball and Ardex alternatives although the solutions seem to be designed for use in the building trade, on new floors that still contains moisture, F-Ball/Ardex liquid DPM is then put on it so building work can proceed without the moisture damaging anything that's going to be put on top of it. Which sounds to me like these are temporary measures and not something designed remain an effective DPM for the life of the building.
I want to rip out all the old bitumen/Asphalt then use either the F-Ball F75 or the Ardex 2 coat DPM to cover the floor, prime it with ARDEX WPM 200 or an F-Ball alternative before covering it all in a latex based self levelling compound.
Has anyone used any of these products in this kind of scenario and are they effective?
Living with the asphalt would have been better but with the damage I would rather rip it out, put down a liquid DPM and tile the surface.
