I am doing a quick makeover job on my kichen - until I can do a better extension in a few years time. The floor is part concrete and part boarding where the original extension was done.
As a result, the Vinyl covering has cracked along the join.
I want to put down a new Vinyl covering to last me another 5 years or so.
I haven't lifted the old flooring yet as it is glued down exremely well but pretty sure they have used thin board under the Vinyl .
What do I need to do to fill the crack to ensure it doesn't split the covering again?
