Our cloakroom has vinyl flooring glued to concrete floor. It seems well laid, and well glued! - and I don't want to have to take it up, but the colour/design is dreadful. Can I cover it with cork tiles and if so what adhesive is best? I'm told I should scratch up the surface first with a wire brush to let the glue penetrate.
Thanks in advance for any advice!

Impact adhesive. or Contact Adhesive, depending on whom you buy it from.

Evostik say you shouldnt use their impact adhesive on vinyl as the plasticisers in the vinyl will bleed into the adhesive and affect the bond. Presumably its the same for all impact adhesives. I think you will have to ask some adhesive manufacturers for advice or take it up.

look at the F-Ball website mate,you will want to look into the styccobond range,there is quite a few in the range.(dont know which it is off hand tho)...but they will have what your looking for.

Many thanks to all for help. I note at least one impact glue not suitable for vinyl. Styccobond range looks promising - will investigate.
