Around the Marietta square, garages are older and smaller, with paint history and clay that walks in from brick walks. Flake after a real grind is the residential job. Shops toward the industrial side want a heavier floor because oil is normal there.
Tell us which building and whether it is heated. A January shop with the door open is not the same cure as a closed garage off the square.

In an older, compact garage near the square, the floor may have several layers of paint or sealer rather than clean, open concrete. A contractor should identify what is on the slab and remove coatings mechanically. Diamond grinding creates a consistent surface for the coating to bond to; acid etching alone may not remove paint or prepare every area evenly.
Ask how the crew will check the concrete surface profile, or CSP, after grinding. The coating needs a suitable texture, not a polished surface or loose dust. Cracks and control joints also need separate decisions: a stable crack can often be repaired, while a joint designed to move may need to remain flexible or be treated as a joint rather than filled rigidly.
A dry-looking slab is not proof that it is ready to coat. Moisture vapor testing, such as in-slab relative humidity testing or a calcium chloride test, can help assess moisture under the conditions measured. Ask which test is planned, what the result means for the proposed system, and whether the product's stated moisture limits are met before coating begins.
A shop floor where oil is part of daily work needs more than a color choice. Ask how oil-contaminated areas will be cleaned and mechanically prepared, and whether damaged or soft concrete will be repaired before coating. Oil left in the pores can interfere with adhesion even when the surface looks clean. The quote should explain the preparation steps, not just list a coating name.
For a flake floor, the system usually includes a prepared slab, a compatible primer when specified, a base coat, broadcast flake, and a clear top coat. Ask whether the flake will be fully broadcast or applied sparingly, and how the finished texture will be sealed. Slip resistance depends on the texture and top-coat build, so discuss cleaning needs alongside traction.
Temperature and humidity affect installation and cure, especially in a shop with an open door or a garage that is not heated. Ask for the product's application limits and the recoat window, plus the time before foot traffic and vehicle use. A rushed return to service can damage a new floor. For bright areas, ask about UV stability; some epoxy finishes can amber with exposure.
Testing is worth discussing, especially if the slab has moisture signs, a prior coating failure, or uncertain conditions. Relative humidity probes and calcium chloride tests assess moisture in different ways. Ask what method will be used, what the readings mean, and whether the proposed system allows those conditions.
Only if the existing layer is firmly bonded and the coating system permits it, which needs to be assessed on site. Loose, peeling, or incompatible paint can take the new floor with it. Ask how the crew will test adhesion and whether mechanical removal is included.
Not automatically. Control joints are intended to manage concrete movement, so a rigid fill can crack or separate as the slab moves. Ask the installer to identify joints and explain whether each will stay open, receive a flexible treatment, or be handled another way.
Resistance depends on the complete coating system, concrete preparation, and cure, not just the top-coat label. Ask what vehicle-use time the installer recommends and whether the system is intended for hot tires. Avoid parking on the floor until the stated cure period has passed.
Follow the coating maker's care instructions and wait until the stated cure period is complete before routine cleaning. In general, remove grit that can abrade the finish, then use a compatible cleaner and avoid harsh chemicals unless approved. Ask whether the chosen texture needs a specific cleaning method.
