Hi all, sealing old concrete floor with Wickes Liquid DPM before levelling with Wickes high performance compound, only trouble is the Wickes product page specifies that pretty much nothing will bond to the DPM stuff.

If I dusted the wet liquid DPM with kiln dried paving sand would this provide a good enough key or does it even need to bond considering the levelling compound will only sit there with stone tiles on top??

Thanks in advance.

Ho Shamo,

Tough one this, like the idea of dusting with kiln dried, but odd that they (Wickes say) nothing will bond with DPM. You need to get on to their tech desk? Would surmise that a Visqueen DPM could be laid over the top and then latex poured over that? But as I say, check with their tech department.
