Hello mattysupra. Please excuse the approach, but I am nearly ready to fit a Engineered wood flooring. Part of it covers existing floor board and one area covers 10ft x 10ft on concrete floor. I have been told to nail it at an angle through the tongue by some people other have told me to glue it. (they say it stops the wood splitting) I am still at a lose on how to fix it to the concrete flooring. The origanal floor board are with your 2/3 mm defiance over the area. I look forward to your reply. Many Thanks Ian (I note your Solihull I live in Nuneaton about 15 minutes away)

hello, not all engineered wood floors need to be glued or nailed. This depends on the size of the planks and if they are designed to be floated. If the instructions say float then float them.
However if the flooring is designed to be glued or nailed, in your case i would advice either way. To nail the floor you will need to plywood both floors with a thick plywood, maybe 18mm if you use the staple method through the tongue (nails/cleats are more for a solid wood which will need thicker plywood) . This will involve alot of drilling and pluging on the concrete half to secure the plywood.
If you fancy doing the glue method then i would advice you plywood over your floorboards with 4-6mm plywood and then do a full screed (self levelling) over the concrete and the plywood so you end up with a perfectly flat subfloor. Then you can glue both sides no problem.
there is a sticky at the top on how to prep the floor.
