hey guys, been trawling through the forum and have come across an re-occuring difference of opinions on if you can tile straight on to plywood. i Can see the advantage of priming the base side and then screwing down but does this substrate not expand and contract over time, would this be a case when a flexible addy is used would the moisture in the addy not effect the ply or should a decoupling matt be used ????
cheers all
