Thread: T&G floring direct to concrete, parky direct to concrete.

Did my floor with bearers.

Only 19mm thick.

It allowed me to Secret nail the tongue and groove to the bearers to hide the nails.

I did seal the concrete first.
I dynabolted and glued the bearers to the concrete
I secret nailed and glued the tongue and groove to the bearers.
I have a small step down into the wet areas.(38mm)
I have no step at the sliding doors, Worked out just below the door frame.
I had to move the vertical blinds on the sliding doors up the wall 38mm rather than shorten the blinds.
I also replaced all the skirting board with thicker (19mm) so as to hide the 10mm expansion joints around the walls.

I can recommend using the bearers.

Do you mind saying why not using bearers?

Maybe I can swing you around to my way of thinking with some discussion.

G'day Soundie.

Direct stick no worries.
Use 12mm or 14mm overlay T&G.
We do 12mm and E.Maculata (Bruce) does 14mm.

Bostik Ultraset adhesive.
Ensure the slab is level. If not use a leveling compound.

Go to www.timber.org.au and download the fooring fact sheets that will give you more info than You will get here.

Larry and Dusty can give you more hands on experience with direct stick than I can.

thanks trevor, I'll have alook at the link.

Whats the diff between standard t&g and overlay flooring?
Is it just thinner?

the reason I wont be laying an underboard or beraers is that there are existing floorings, multiple and " we wont be having a big step" in the flooring.

10 to 15mm I can probaly get away with.
but 20mm forget it..... it wont pass inspection.

with direct stick whats the expectations on provision for expansion?

cheers

Fair enough with the step up or down.

Our step up or down is in the Wet areas and garage.

We may at a later date retile the wet areas.

As our steps are in doorways it isn't too much of a problem I guess.
