Hi, 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? Thanks, Stephan.
