I'm putting in new kitchen cabinets and had to pull up some of the sub flooring under the sink and dishwasher plus a little. I had planned to put down vinyl planking directly over everything. The old floor is almost level with the new except for 1/32" ? 1/64" ? difference. I did my best to make a straight and accurate cut but there are minor gaps as you see in the picture. I really don't want to put down Luan plywood on the whole floor as an overlay. The gaps you see in the sub flooring will be under the cabinets or stove except for where you see the pencil, along there for about 8', your toes and feet will be. Can I pay the padded on the back of the vinyl planking over these cracks or should I fill in? And with what? I have Easy Sand 45 and Thinset.
