T&G Chipboard Questions

[curium]

Hi All,

I'm laying some 22mm T&G chipboard in the ground floor of my 1934 semi-detached property.

This has been prompted by the need to remove the existing floor (which was vinyl, glued to the floorboards) to deal with issues affecting various services.

I've never done this before so am having make decision as I proceed.

1. I have a kitchen at the rear transitioning to a hallway to the front door and a living room off the hallway. Is it the done thing to cut boards at thresholds and board out each room separately or should I attempt to join boards across thresholds using the T&G?
2. If where adjacent boards meet with the T&G doesn't line up with a joist, should I insert a piece of timber to ensure these are all supported?

Many thanks all

Yes, but you try to arrange your boards so that you aren't left making weird or complex cut-outs, if that makes sense

If where adjacent boards meet with the T&G doesn't line up with a joist, should I insert a piece of timber to ensure these are all supported?

It is always a good idea to support end joints where they don't "land" half on a joist

As it's your first time a couple of minor asides. If you weren't aware you need a slight gap between the chipboard and the walls (expansion gap, helps avoid the floor making creaking sounds if it rubs against the wall). You should always start with a tongue to the wall as this leaves the groove edge that you can "persuade" into position (doing this can crush the tongue if you try to "persuade" it). You shouldn't be too stingy with glue, either, and you ideally should glue the boards to the tops of the joists and at all T&G joints. The best way to get a tight joint is, believe it or not, to use a length of something like 4 x 2 softwood (about 4ft long) placed against the groove edge of a board and "helped" with a few taps from a small sledge hammer... (well, it works for me, I kid you not)
