Enginnered Flooring

[SteveF]

My Son has a load of boards he acquired
they are oak t&g but just push together so no click and fit

can these be stuck down on concrete? if so best option for fitting please

I have an engineered oak floor stuck directly onto concrete. They sealed the concrete first with an extraordinarily expensive resin compound, the red stuff in the picture. They then stuck the boards down with some extraordinarily expensive glue :shock:

 

[SteveF]

not the answer I wanted
but I guess is the correct answer

I am already poor

was hoping someone would say just glue it together or gripfix it down

Just glue it together or gripfix it down. Sorry couldn't resist.

If it is on top of screed that is dry and flat, I would think you could lay a 3mm foam underlay then lay the engineered oak boards as a floating floor.

I think for floating floors the tongues are glued with pva.

Make sure sufficient expansion gap is left around perimeter. Ideally 12mm and hiddenunder the skirting.

As Robin says.i did exactly that and it worked fine. The expansion gap is a must.

 

[SteveF]

That was the answer I was looking for

+1 for what Robin said.

I laid mine on a 3mm-ish foam underlay which is foil-backed - the foil side goes next to the concrete - and extend it a couple of inches at the edges of the room tucked under the skirting if possible.

IMO the underlay also makes the floor much "quieter" to walk on.
