I presume that you are regarding to the underlay for electric under floor heating?

If so this is usually secured using floor tile adhesive

You can use spray contact adhesive. You spray the concrete and the underlay separately and then once they are both dry you can lay the underlay and press firmly for a second or two. You can get the spray from screwfix and most other trade/DIY merchants

Spray adhesive on edges and joins. Tape all underlay joins too

Hi I'd would use adhesive to stick the underlay to the concrete floor


Answered 25th Nov 2019

Spray contact adhesive would be the best method but double sided tape could be used depending on the sub floor


Answered 25th Nov 2019

Double sided tape will do but make sure the area is clean as dust free


Answered 26th Nov 2019

Spray adhesive is the best option, I would not advise double sided tape it can dry out and go crispy and also not get a good bond unless you spray adhesive around the room first to seal the dust etc, ( then you wouldn’t need the tape anyway! )

Spray edges and the joins and then secure the joins with tape if you want a proper job.

Spray adhesive around the perimeter , close as possible to the floor , then fold half the underlay back and spray the floor and underlay you’ve rolled back to double stick , shake the van as you stay to create a webbing formation for better grab. Place underlay down and apply pressure with hands to secure to subfloor.

If you open your carpet out first in the position ready for fitting pull half back fit your underlay then put the carpet on top repeat the other side this way you don't need underlay or you could use pva adhesive just put some in a washing up bottle run a small bead cross on the floor this a great way to secure the under and you don't get all the bad fumes from spray adhesive
