Richardson garages were poured with the ranch houses and have been parked in ever since. Stains are old. Tires are hot. A new coat starts with a grind that gets back to concrete, not with a thicker layer of hope.
Some of these houses are opening a room for a parent or a studio. That conditioned space can take a metallic or solid floor. The car bay should stay a flake system unless you enjoy seeing every rock the tollway threw.
The photo is an example finish, not a documented Richardson job.
Before choosing a coating, check what the slab is doing below the surface. A moisture-vapor test can help identify conditions that may interfere with adhesion. Calcium chloride tests measure moisture emission at the surface; in-slab relative humidity testing measures conditions inside the concrete. The right method and acceptable readings depend on the coating system. Ask for the test results and the product limits they are being compared with.
Diamond grinding mechanically removes weak surface material and opens the concrete to a specified profile, often described by a CSP number. Acid etching is less predictable: it may not remove old coatings or contamination evenly, and rinsing can leave moisture behind. Ask how the installer will confirm the surface is clean, sound, and rough enough for the planned primer and base coat.
Repairs need a plan before coating starts. A crack may be active or stable, and a control joint is designed to move; filling or coating over every line the same way can lead to a visible return crack or failed coating. Ask which cracks will be repaired, which joints will remain flexible or visible, and how those details will be finished at the edges.
When a garage bay becomes a conditioned room, its use changes the coating decision. A solid or decorative finish may suit a room, but the slab still needs suitable preparation and moisture conditions. Ask whether the proposed coating is intended for conditioned interior use and how its finish will handle furniture, cleaning, and light. The same system should not be assumed to fit both a room and a vehicle bay.
A complete quote should describe the layers, not just name a finish. Look for the planned primer, base coat, flake broadcast if included, and protective top coat, along with crack and joint work. Confirm whether flakes will be broadcast to refusal and scraped before sealing. Those details affect coverage, texture, and how evenly the finished surface wears.
Top-coat choice matters where sunlight reaches the floor. Some epoxy finishes can amber with UV exposure; UV-stable polyaspartic or polyurea top coats can help preserve appearance, depending on the full system. Ask what layer provides UV resistance and whether the chosen texture is appropriate when wet. A smoother surface can be easier to wipe, while added texture can improve traction but hold more dirt.
Ask which test will be used, where readings will be taken, and what limit applies to the proposed coating system. Request the results before installation. If readings exceed the system’s limits, the contractor should explain the options rather than covering the slab and hoping the coating bonds.
Ask how the required concrete surface profile will be checked and whether the preparation method removes existing coatings and contamination. A clean-looking slab alone does not prove it is ready. The surface should match the coating manufacturer’s preparation requirements before primer is applied.
Not automatically. Control joints are intended to accommodate movement, so a rigid fill or coating bridge can crack or separate as the slab moves. Ask which joints will remain visible, which will be filled, and what flexible or rigid repair method is appropriate for each location.
Follow the system’s stated cure schedule for vehicle traffic, not just the time it takes to feel dry. Temperature and humidity can change cure rates, and a coating may need longer before it can handle hot tires. Get the return-to-service timing in writing before the work begins.
Sweep or dust-mop grit regularly, then use a mild cleaner and a soft mop or brush as directed for the coating. Avoid harsh chemicals or abrasive pads unless the system instructions allow them. Promptly remove oil and other spills, and ask for the care guidance for the installed top coat.
