The previous owner installed vinyl tiles of reasonable quality in the
basement laundry room. Unfortunately, he must have done it in a hurry
and there are small (~1 mm) gaps between some tiles. He used a
portland cement/Latex primer on the concrete before laying down the
adhesive tiles so I'm confident the floor itself is stable. Is there a
good liquid vinyl product out there that I could color to match the
edges of the tiles and use to fill the gaps?
