Screed and wooden floor

[morgan4367]

Hi
Ive got to qoute on laying porcelain floor tiles 60 x 60cm on a floor 24.5m2. Half the floor is quarry tiles which are soundly fixed, and the other half is chipboard. I take it you would use a decoupling membrane, my question is do you use it on the whole floor or where the two subtrates meet. Also do you use a single flexible adhesive to fix the membrane, and what adhesive would you use to fix the tiles standard,single or 2pt flexible adhesive.

Thanks. Tony

Is the chipboard section fixed or floating.?

Hi Dave
The chipboard looks fixed.
