Most janitorial supply houses carry quality floor care products.
I always used Johnson Wax Products, their Professional Series on my Armstrong VCT garage floors. For best results all the old wax and dirt needs to be removed first. Using Johnson’s Professional Floor Stripper with my Low RPM 20” polisher with a red pad. It’s most important to rinse floor several times with clear water after stripping. After drying, then hand apply Johnson’s Professional Floor Finish (wax) with a mop. Once dried I bring out the High RPM 20” floor polisher using a white buffing pad, misting with Johnson’s Professional Maintenance Buffing Wax. In higher traffic areas, this spray buffing will bring out the luster between semi-annual or annual stripping. I always had floors that looked like Wally’s World. It’s a lot of work,, that’s why I went to epoxy floors.
