My kitchen floor is suspended but quite firm. It previously had quarry tiles laid on the old 1950s lino and the grout never cracked. It is long and narrowish - 19ft by 8ft 6in. I am going to try to get away with 9mm ply, screwed at 10" centres, as I don't want the finished floor to be a lot higher than the hallway. Do I need to leave expansion gaps between the 8x4 sheets of ply or can I butt them?
Should I leave expn gaps betwen plywood under floor tiles

Hi Roy,
Just butt one sheet to another or maybe 1ml.gap between.As long as you use a WBP plywood,and stagger the joints it will be ok.If it was me,I would screw it down at 6" centres to give you a better surface for tiling.Use a flexible tile adhesive,the powder type, and powder type flexi grout,and mix it to the manufacturers instructions.Don't mix to much at a time,keep the bucket and tools clean each mix,and good luck.
