Advice needed on overlay flooring installation.

HI im in the preocess of preparing the slab, pulled out all carpet and im putting in blackbutt 12mm overlay.

I will be sealing the concrete.

My dilema is what s the difference between the three brands of sealer and glue. ie Selleys, Sika, and Bostik?
Why do you recommend one over the other? Do the boards have to be chocked tight once their glued down and do you put wieghts to hold them down while the glue dries?

Is it a better method to seal concrete, lay down 15mm plywood and glue the floorboards to the ply?

Another thing is im also replacing the tiles in lounge and living areas, it seams to be some sort of motar or screed that was laid over the concrete and tiles where glued on that.
Would it be best to remove it or remove tiles and glue then seal it and glue floorboards?

Some advice would be really helpful
