Mixed Subfloors

For areas with mixed sub floors, most commonly extensions where by the ground floor has a suspended floor and the room is extended with a concrete screed it is important to level the entire area and to ensure the ridge between the two areas is removed.

Only use one fitting method to install the floor in the area unless the floor is separated by the use of a T section at the join of the subfloors.

The best way to install the floor is to ply the entire area (see Panel Products Subfloors) and either nail or glue the flooring to the ply.

Refer to moisture testing section to ensure the tolerance for moisture is met and the correct use of vapour retarders for each area.
