St. Petersburg garages are often small, older, and a short walk from salt air. Sand tracks in. Moisture readings matter more than a color trend. Flake is the practical floor because it hides grit and adds grip when a storm wets the threshold.
Street width is the other constraint. If the garage opens on an alley or a narrow block, say so. A crew can coat the floor. They still have to park the van.
