Hello!
The previous owner of my unit has done a bit of a dodgy DIY job on the floor. There’s about a 1cm gap between the wall and the floor. It’s a bit of a nightmare in terms of being a dirt and dust trap.
I am interested in laying vinyl flooring over the top of the wooden floor, would I need to fill these gaps before I do that?
If so, what can I do to fill these gaps?
Thank you in advance!
