I will soon be laying a small tiled floor over a joist floor. The Joists wil be covered with 18mm WBP plywood that I will screw down with an overkill of screws and probably glue as well. I believe a good approach for fixing my tiles to the plywood (tiles are 330mm x 330 mm porcelain) will be to use a BAL fastflex adhesive (seems to be popular choice).

I was wondering what the difference (if any) is between the single part fastflex and the two-part stuff? If there is no difference then I imagine its less hassle (no mixing to do or get wrong) to go with the single part stuff.

Any advice much appreciated.

Steve

Fastflex is a good choice for your floor though in actual fact a single part flexible will do as you have a good solid surface to tile onto. My own personal favorite for wood floors is Ardexflex 7001 if you can get it.

Thanks for your input but I am still still not sure what the difference is between the two versions of fastflex?

Any ideas ?

steve, you do mix single part flexi, with water. The 2 part is mixed with a latex type liquid

those prices are terrifying

Any ideas ?[/quote]

single part fastflex is grey!
not to be used with travertine ,glass etc etc....

Has Anyone used this singlepart fastflex ?
Is it as good as the the two part stuff?
