We have a 10,000 sqft concrete shop floor. Every year or two we clean, strip, seal and finish our floors with these Zep products. The most important step is to mop the floor with clean water several times before laying down sealer and finish. We use the stripper with a floor scrubber, mop it up, then follow with another floor scrubber using the neutral cleaner, that way it gets up a of the stripper that gets dried out or flung around and missed. When applied carefully, you get a perfectly gloss finish. Also if you skip the sealer, you will see more imperfections in the base material. The sealer helps keep the concrete looking more uniformly wet.
Also the best way to apply this product is with a wide microfiber mop such as the Rubbermaid Hygen Q570, Q424 and the telescoping angled handle. we used to use the rayon mop heads but they take longer and leave streaks. the streaks will dry out and be fine, but they wind up taking like 2 hours to fully dry between coats.
