hello Folks,
its a tiny area. 1.8 m2. Joists are solid 3 inch wide. Area is upstairs close to joists end. Have screwed the osb every 300mm. 18 mm osb. Thinking of putting on a few coats of sbr. Area feels solid but of course I cannot really control any moisture absorption or expansion/contraction. Cannot raise floor level to place ply on top. Am I crazy thinking of this or might this work? Unfortunately tiles are big, 75 x 20 cm. Advice appreciated. Thanks, John.
