[quote=Stone;15077]Cheers for the reply. The tiles are 8mm thick. The only adhesive I could see for porcelain was Wickes own brand 'For stone and percelain wall and floor tiles"

Is the main problem that they don't absort water like ceramic?[/quote]
Totally right,they don't absorb moisture like ceramic almost all porcelain are what's known as full bodied or fully vitrified -if they're a light colour,use a white rapid set....
