thanks for the responses!
There is black vinyl moulding around the base of the cabinets. So, I
guess I can cover up where the new vinyl will touch the old..
Along the walls, there is wood shoe moldings..
However, I forgot to add that the genius that put the vinyl sheet down
just put it on top of bare floorboards. there are some holes in the
vinyl and an area I peeled up and it is just bare floor board. plus,
it is not completley glued down. There are areas that if I press down,
there is some give until I hit solid underneath...
I think some sort of liner is in order as well, correct??
