Thanks for the info Dan

If anyone is able to get hold of Mapei adhesives in their area they would be well advised to phone the Mapei Technical Dept in Brimingham - ask for the little black book - gives a technical breakdown of every adhesive they stock.
They have a wide range of flexible one part adhesives that are high grab, non slip, suitable for porcelain & UFH. No need to prime on some substrates.
They do a latex additive - when added to their flexi adhesives it's like s**t to a blanket.

The little black book is so good because it has a glossary that gives you every type of substrate & adhesive - which to use / prime / which additive / which primer / & when to phone technical dept.

Bloody brilliant !!!!!
