Laying Tongue And Groove Chipboard Flooring On Joists

Before you start follow the recommended requirements for board sizes and tongue and groove boards.

Laying tongue and groove chipboard flooring on joists.

But to start off we will need to remove the tongue so the plywood is tight with the exterior icf walls. The tongue and groove are only along the 8 foot edges. Then lay a chipboard flooring panel down adding a screw to the tongue at each tongue and groove joint to secure it to the joist below. Tongue and groove does not have to end on a on a joist as long as the joists are not further apart than 350 400mm 14in 16in.

For an even better and longer lasting job when i lay chipboard fooring i always pva glue the joints and use a bead of flexible glue like sikaflex adhesive on the joist to ensure there are no squeaks you need to fix later once the floor boards are screwed down tight on to the joists. Firstly apply a continuous bead of adhesive to the joists and noggins on which the chipboard panels will be laid. On the four foot edges your seams will fall on joist tops so no need for tongue and groove. For subflooring you use tongue and groove plywood.

The method for laying a tongue and groove floor is similar to that used above. Standard size sheets are 2400mm x 600mm and available in two thicknesses 18mm and 22mm. Although chipboard floor boards are available in 18mm and 22mm thicknesses you will almost certainly need 22mm thick for any normal modern flooring application. The tongue and groove edges make for a strong bond between the boards.

Chipboard flooring with tongue and groove joints is commonly available for flooring applications.
