Recomend an adhesive

[belgiumboy]

Hi Guys

just a quick one

Going to lay an engineered oak floor over the existing floor which is red clay tiles, anyone like to suggest a suitable adhesive, don't want to float the floor as she who must be obeyed thinks it feels like laminate.

thanks in advance for your help

How porous are the clay tiles or are they sealed? If so with what?

It could be that SWMBO has to change her mind. If you get a decent underlayment (with DPM) it will not sound like laminate - if your wood floor is of decent quality too that is.

The tiles are normal quarry tiles, We've been here 4 years and they haven't been sealed by us but thats not to say they have never been sealed. They are all very sound, no loose ones and very level.

The flooring that we are going to use is 15.5mm thick with 6mm facing, thick enough to float???

More advice always welcome

If you are laying on quarry tiles you need to be careful. Quarry tiles can be laid onto: a normal concrete screed that incorporates a dpm.
a thin screed just laid onto gravel/earth.
a bed of earth!

You need to check what your tiles are laid on and also to test for any moisture before you put any wood flooring down.

Is the overall thickness of the wood 21.5mm? - you would be ok to float.

Tiles are laid on a suspended re-inforced concrete floor (basement below) total thickness of oak planks is 15.5mm

Also, it might look flat to the eye but have you checked for level with a 2/3 metre straight edge ?

You need to check levels when floating aswell.

Your wood-engineered floor is 15.5mm total thickness: a 6mm Solid top layer and 9.5mm backing? What type of backing does it have? Plywood, pine, OSB?
In first instance the construction does not sound right, most W-E boards should have a backing at least 2 x the thickness of the top layer (depending on the type of backing used) to prevent the different working of the strong top layer compared with the softer, weaker backing cupping the whole board.

God, this is getting really technical now

The boards are good quality with plywood backing, I'm assured that it's not from China!!!!!! this is the quality if it means anything to you guys QFA/1B

The tiled floor is very level, was laid many years ago by a skilled craftsman, I've checked it with a 3m straight edge and level.

I can also go for a thicker board at extra cost total 21mm with 6mm facing and after checking the 15.5mm has a 4mm facing.

Still confused as which would be the best way to go, glue or float, what are the pro's and con's????

I have glued before with great sucess but that was onto a concrete screed which is more normal.

I've not bought the boards yet so have the choice to change spec, the price it not so important as these are coming direct from the importer.

Again your advice is most important
Thanks

That sounds better

If the floor is level you can install it floating on a combi-underlayment (containing a DPM), this would be the way we would install it. If you need more insulation because you worry about sound, use Timbermate Excel as underlayment
