How to choose a garage floor coating contractor in San Antonio.
The difference between a floor that lasts 20 years and one that peels in two usually comes down to prep and the fine print — not the color. Here’s what to ask a San Antonio contractor before you sign.
Prep is everything
Ask exactly how they prep the slab. Diamond grinding opens the concrete so the coating bonds mechanically; an acid etch (or no prep) is the #1 reason coatings lift and peel. If a San Antonio bid is far cheaper than the rest, skipped prep is usually why — and you’ll pay again to grind off the failure and redo it.
Warranty red flags
- Does the warranty cover both materials and labor? Many “lifetime” warranties quietly exclude one or both.
- Are there moisture exclusions (MVER thresholds, Tramex readings) buried in the terms? Those are often escape clauses to deny a claim.
- Do they apply a moisture-mitigating primer on every job, or only after they “find” moisture on install day and upcharge?
- Can they produce technical data sheets for the products they’re using?
- Are they licensed, insured, and local, with San Antonio-area references you can check?
What matters locally
San Antonio sits on expansive South Texas clay that swells and shrinks with the seasons, quietly opening hairline cracks in slabs across the area. Add long, humid summers and the occasional hard freeze, and a floor coating has to flex with the ground rather than sit rigid on top — or it telegraphs every crack the soil underneath creates. Many area slabs are newer suburban pours on clay-heavy lots, where movement is normal and crack repair during prep is the difference between a finish that lasts and one that splits within a year.
That’s why moisture control and the right prep aren’t optional add-ons in Greater San Antonio — they’re the job.
