The main factors behind the price
Floor size matters, but preparation is often the bigger variable. Existing paint, oil contamination, cracks, moisture and difficult edges can all change the work required before coating begins.
The finish also matters. A full-flake garage system, an outdoor driveway coating and a commercial floor face different conditions and should not be priced as if they are identical.
Why the cheapest quote can cost more
Coatings rely on their bond to the concrete. Skipping mechanical grinding or coating over an unsuitable slab may lower the initial quote but increases the risk of peeling and early failure.
Ask every installer to state the preparation method, coating stages, cure times and warranty in writing.
