Basement Floor Coatings for Finished & Utility Spaces
Basements are where coating mistakes show up first — moisture pushes through, coatings bubble, and a finished space turns into a problem. Onyx assesses the slab before recommending a system. If the concrete is a good candidate, a coating or polish can turn a basement floor into a clean, usable surface. If it isn't, we tell you before you spend money.

Learn MoreSurface Assessment & Prep
Moisture is the single most important factor for a basement. We look for signs of vapor, efflorescence, and prior failures before recommending any system. A coating is only right when the slab will support it.
Installation & Access
Basement access is usually tighter than a garage. We plan around stairs, low ceilings, and ventilation for off-gassing during cure so the project runs cleanly.
Finish & Maintenance
We discuss whether a breathable polish or a sealed coating fits the space, and choose a finish and sheen that balances appearance, cleanability, and the slab's actual condition.
