Laying ply on old timber floor to make it more even
Anonymous user 26 August 2019 - 1.19 PM
In terms of laying plywood to even out an old timber floor : 1. Does the plywood need an expansion gap with the wall? 2. Does the plywood need expansion gaps between sheets? Thank you

I fit mine with the boards tight together and tight to the floor, unless the floor is particularly uneven. In which case I leave a small 5mm gap around the perimeter.

Unlike laminate floors which float over an existing floor and have expansion gaps, plywood is usually screwed or nailed into position and expansion gaps are not necessary.

You should fit the plywood sheets tight together , but always leave a 10mm expansion gap at the perimeter.

St Lukes, LondonPly being an engineered material, does not expand too much under normal conditions so if it is not being place where moisture is high there is no need to leave gaps between sheets, however the perimeter will definitely need room for expansion. 10mm should be enough
