Damp Proof Floor In Garage

badboyblast

Hi all,

I have a concrete shed with a proper roof on it insulated and I recently got the walls slabbed and plastered and I want to finish the floor and put down a laminate floor.

There was no plastic barrier put into the foundation when built , is there anything I can put down like a plastic membrane that would stop moisture creeping up through the floor ?

Can anyone recommend a sealer or a barrier to put down ?

Appreciated

This will not work, it needs to be used in conjunction with a product like i have linked below.

http://www.f-ball.com/en/product/stopgap-f77-waterproof-surface-membrane/ is your one, you can pick it up from any decent flooring shop (read not woodies etc).

I'm after putting down a floor in a steel shed. I first put down overlapping rolls of 600mm dpc, which were glued together using PVA. I then put 50mm K-boards on top as insulation amd 10mm ply on top to walk on. Floor has been down about a month with no problems so far.

Sounds great. So you didn't actually treat the concrete base , what are k boards ?

Could I actually lay dpc and bond it and then put click laminate above this or would it be risky
