Sandy Springs houses often have a garage that was painted once and a lower level someone now wants to use. The garage wants flake that hides clay from Roswell Road. The lower level wants a moisture test and then a calmer solid or metallic floor.
These are not new-slab problems. They are prep problems. If a previous coat is peeling in the tire lanes, that is the photo local pros need.
The photo is an example finish, not a documented Sandy Springs job.
In Sandy Springs, an older garage floor may have several layers of paint or coating, and the visible surface does not show how well those layers hold. A contractor should check for peeling, hollow-sounding areas, tire marks, oil, and previous patching. Coating over a weak layer can make the new finish fail along with the old one, leaving a larger removal job than starting with sound concrete.
Diamond grinding mechanically removes weak coatings and opens the concrete to a controlled surface profile, often called CSP. Acid etching is not an equivalent shortcut: it may leave residue, miss coated areas, or create an inconsistent profile. Ask how the crew will verify the slab is ready for the chosen system, including at the tire lanes where an old coating may be most stressed.
Cracks and joints need separate decisions before coating. A stable crack can often be repaired with a compatible material, then ground flush; a moving control joint generally should not be rigidly bridged as if it were a crack. If the coating must be removed and the slab repaired again, that means more grinding, patching, dust control, and time without normal garage use.
A lower-level floor calls for a different check than a garage. Concrete can transmit moisture vapor even when the surface looks dry, so ask what test will be used and whether the result meets the coating maker’s limits. Calcium chloride testing measures moisture emission at the surface; in-situ relative humidity testing measures conditions inside the slab. Results from one method cannot simply be substituted for the other.
Ask how each layer is chosen: primer for the slab and test results, a base coat, and, if selected, a full flake broadcast followed by a compatible topcoat. Confirm whether flakes are fully covered or scraped back to a chosen texture. Too little texture can feel slick when damp; too much can make routine sweeping harder. The intended use should guide that choice.
For a garage with sunlight at the door, ask how the finish handles UV exposure. Epoxy can amber over time; polyaspartic and polyurea topcoats are often chosen for better color stability, but formulations vary. Confirm the temperature and humidity limits, cure time before foot traffic and vehicles, and recoat window. The calendar alone does not tell you when the floor is ready.
Look for peeling, bubbles, worn tire paths, or edges that lift when scraped, but a visual check is not enough to confirm adhesion. Ask the installer to test representative areas and explain what will be removed. The new coating should not depend on a loose layer beneath it.
Yes, appearance alone does not establish that a slab is suitable for coating. Ask which recognized method will be used, when it will be performed, and how the results compare with the selected system’s limits. If results exceed those limits, the installer should explain options before coating begins.
No. Cracks and joints do not all behave the same way. A stable crack may be filled with a compatible repair material, while a control or expansion joint may need to remain visible or be treated to accommodate movement. Ask what each line is and how the proposed detail will handle it.
Each layer needs to be applied within the system’s specified window for the next coat to bond as intended. A delay, or applying too soon, can require extra preparation or lead to a weak bond. Ask how the crew will track conditions and timing between primer, base coat, flakes, and topcoat.
Do not use a touch-dry surface as the signal. Vehicle traffic usually requires more cure time than light foot traffic, and temperature and humidity affect the schedule. Get separate return-to-service times for walking, moving stored items, and parking, and follow the installer’s written guidance.
