Hi Jim. I strip and seal and maintain large area vinyl floors in heavy industrial areas as well as maintain apoxy flooring I use The BETCO hard as nails sealer you can drive fork lift trucks over it. To put the sealer down after stripping and rinsing I use the BETCO back pack applicator and pad About £120.00, the chemical sealer comes in a plastic container 5lt which fits into the back pack holder and feeds the chem down through the handle and into the applicator, in most cases only one coat is required it's fast non messy dries in 30 minutes and totall resists all scuffs, skid marks, mettal filings (swarf) oils and careless cleaning staff utilising harsh chemicals to maintain. It comes fro the states but is available through their UK distributer.
