NoMorePly on concrete

[andyfr]

Hi

I am going to be using 6mm NoMorePly on a concrete floor, will their adhesive bond it to the floor without any problems? It is a 1971 house so it's well cured. I assume I will have to clean it and maybe prime as well. Any advice on preparation gratefully received.

I will be using this as the base for Karndean gluedown planks.

Thanks

Andy.

The manufactures recommend priming concrete with their SBR...

Thanks for that link, very helpful.

1971 your concrete might not have a damp proof membrane ? Can you see any sheet around the perimeter.
any reason why you aren’t using a smoothing compound over the concrete.

The house was built by the previous owner who was a local builder at the time. As I understand it, a DPM became a regulation back in the 60s.

I took the wall down between the kitchen and dining room so there is a slight difference in height so I don't want to use a self leveller as it will mean that I will have to do the entire downstairs floor.

1965 but most houses before 1980 don’t have a effective Dpm under it so laying glue down LVT will stop the floor breathing which can cause damp. Test it and if it has moisture put a liquid Dpm over it.
