Title: floor tiling advice needed
Post by newport_eddy on Jul 3^rd, 2010, 1:14pm

i've tiled a few floors onto concrete/screed/self leveling compound etc but.....

i'm going to do my sisters kitchen, its a concrete floor and she had the old vinyl(ish) yellow coloured tiles you see in lots of newish homes (80's), these have come up with a little elbow grease and a scraper no problem....these were laid onto what looks like some king of black resin which will not come up at all.

can i just unibond onto this first then lay tiles as normal?
should i let the unibond dry totally or tile on it whilst tacky?
should i unibond and then use self level compound for a beter adesion? (floor doesn't need levelling)

any advice be appreciated thanks

Sounds like a bitumen adhesive. I think BAL recommend their Rapidset adhesive for use over that but give their help line a call unless someone here can advise.

You can tile directly onto bitumen with certain brands of adhesive. Don't use Unibond (PVA) as a primer, use the primer recommended by the manufacturer of the adhesive. 2 reasons, 1 is they will not warranty the work if the tiles start coming loose and 2 PVA is not the same formulation/thing as specific tiling primers.
