I wanted to quickly lay vinyl sheet down. I will put hardboard subfloor on top of floorboards at a later date however right now I'm happy to loosely lay it over the carpet. As I mess around with the floors I noticed the vinyl looks quite smooth on the carpet underlay.
So I'm wondering now should I temporarily lay the vinyl sheet on the floorboards(which I know are uneven), on the carpet underlay or even on the carpet??
It will just be temporary but is even so is there a reason to prefer one temporary subfloor aesthetically and functionally speaking?
Thanks
