The floors have vinyl squares stuck to the underlying concrete and work very well for many years. In a few places the vinyl tile has cracked and bits of the vinyl tile is missing showing the concrete underneath. I want to put a new top of vinyl sheet and would like to fill the small depression where bits of the old tiles are missing, what would you recommend to fill the small areas involved, it's only about 2 or 3 mm deep. It was suggested a normal diy filler would do the job but this might break up over time. I wondered what the opinion of others might be.
Thank you
