Hi, I know this has probably been answered already but i have been away from the site awhile. I have a shop with black and white VCT tile and i have heard of people putting a polyurethane finish over the tile. I was wondering if there are any long term reports on the results of doing this and what is the proper procedure? My floor has been in for about a year and was polished once with VCT floor polish. Thanks for the help, Bob
