Laying reclaimed gym floor

[Jonboy74]

Morning All,

I'm hoping someone can help me out.

We are looking at purchasing reclaimed gym flooring (like the stuff in a school hall), to be layed in our hall. It will be layed over the existing floorboards, in the same direction as the joists.

So.....

1: would it be better to lay a ply base first?
2: should we be laying the longest lengths possible?
2: should we glue or nail?
3: should we leave a 10mm gap each side or 5mm (the width of the hall is less than 1m)?

Sorry if these are questions already answered, but I'm getting very confused?

Thanks

Those floor normally have narrow widths and often short lengths, so you do need to glue them onto WBP plywood (12mm preferred)
If you install it like this you can use all the different lengths without a problem.

Leave a gap of 10mm around.

WoodYouLike, it would seem you are the master, so I'm going to tap you up for some more help

Should the ply be glued, nailed, screwed to the floorboards?

Could you recommend a glue to stick the new flooring to the ply?

Cheers

Use screws or staples to install the ply (every 25 cm) and then you can opt for either Lecol5500 or a flexible adhesive like Mapei P990

I've just checked the weather, & it looks rubbish, so I'm going to have a stab at this @ the weekend. Thanks for you help.
