However some people prefer to add another thin layer of subflooring between the concrete and vinyl. This is really good information. In most cases as long as the old vinyl surface is flat you dont need to do anything more for this type of underlayment.
This additional layer can improve insulation and should make your vinyl plank flooring warmer and less resonant. Most vinyl planks do not require anything under them. You also do not need an underlayment if your vinyl plank flooring has underlayment installed however you may need a vapor barrier.
