Surface Preparation

[Lincol]

Hi Everyone,
Newby to this excellent looking Forum and I hope I can be a help in the future. I have just lifted a load of worn out old cork tiles from our porch and my intention is to lay some ceramic floor tiles. The surface is sound concrete but has some remains of the cork tile adhesive remaining. I would appreciate any advise regarding removal of this prior to priming the surface I thought with unibond.

I thank you in anticipation
Lincol

remove as much residue as possible. A sander or angle grinder with a cup wheel will do it in no time.
Dont use PVA, get a tile primer like SBR.

Thankyou for such a quick response, a cup wheel is the way to go, will do.
