What questions should I ask a garage floor coating installer in Orlando, FL before signing?

An Orlando garage floor is not a generic slab. It sits on sandy fill over the Florida limestone aquifer, often where Central Florida wetlands were drained a century ago. The water table is shallow. Ambient humidity averages 70 to 90 percent year-round. The afternoon thunderstorm pattern from late May through September puts saturated air over every open garage door for weeks at a time. The installer you hire has to understand all of that before they ever quote a system. The ten questions below are how you tell a verified Orlando crew from a sales rep working off a national brochure, and what a bad answer to each one actually sounds like.

Why the bid conversation matters more in Orlando than in drier markets

A 1925 bungalow in Thornton Park built on filled marsh is a fundamentally different prep job than a 2018 home in Lake Nona Medical City. The Thornton Park slab has nearly a century of settlement, decades of motor oil from a different era of vehicles, and almost certainly elevated moisture vapor emission from below. The installer has to see all of that on the walk-through and scope it honestly. A salesperson pointing a tape at the floor and quoting square footage cannot do that. Find your Orlando, FL crew through the local hub, and use the questions below at the assessment.

The ten questions, in the order they should come up

1. Are you running a moisture vapor emission test before product selection? This is the question that matters most in Orlando. Shallow water tables and sandy subgrade drive vapor through the slab continuously, and the emission rate often exceeds what a standard coating film can tolerate. A calcium chloride test or a relative humidity probe catches the problem before it bubbles a finished floor. A bad answer is "we have not had problems with that here." That is the answer of someone who has not been called back to assess their own failures. Our note on concrete moisture testing covers what a real test looks like.
2. What diamond grind grit and how many passes on this specific slab? The answer should reference a CSP (Concrete Surface Profile) target and explain that grit selection depends on what is on the slab now. A bad answer is "we acid-etch." Acid etching on an Orlando slab with elevated vapor emission produces a bond that fails from below within months.
3. What basecoat chemistry, and is it rated for high-moisture concrete? The standard for Orlando residential should be a high-solids two-part epoxy. The installer should be able to name the manufacturer and the specific product, plus describe the vapor-mitigation primer option for slabs that test high. A bad answer is vague phrasing like "industrial epoxy" without naming chemistry.
4. Is the topcoat humidity-cured aliphatic polyaspartic? Polyaspartic chemistry uses ambient moisture as part of the cure mechanism, which means it performs reliably in the humidity range Central Florida produces every day. Aliphatic also delivers UV stability through the Florida sun load. A bad answer is "epoxy clear coat" or any standard urethane, both of which stress-cure in Orlando summer humidity.
5. Is this a single-day install for a standard two-car bay? A properly specified polyaspartic system supports same-day installation when the prep is done right. A bad answer is a multi-day install for a standard residential garage, which usually means the crew is using slow-cure epoxy as the topcoat and calling it polyaspartic in the marketing.
6. What is the cure schedule before walk-on and vehicle traffic? The honest number on a properly installed system is walk-on the next morning and vehicle traffic in roughly 72 hours. A bad answer is a week or more, which again points to wrong topcoat chemistry. Our note on polyaspartic install time walks through the schedule in detail.
7. How are you scheduling around the daily thunderstorm pattern in summer? An Orlando-experienced crew schedules installations to land the application window before the 3 to 6 PM convective storm activity rolls through. A bad answer is "we just work around it" or any version that does not acknowledge the daily summer cycle as a planning constraint.
8. What are the specific terms of the warranty? The right number is a Limited 15 Year Warranty covering peeling, delamination, and bubbling under normal residential use. A bad answer is "lifetime warranty" with no documented terms. Lifetime claims without specific written coverage are a marketing tactic covered in our note on polyaspartic garage floor lifespan.
9. How are you handling the settlement cracks and any spalling on this slab? A real installer walks the floor and points to specific cracks before quoting. Filled-wetland settlement in College Park and Lake Eola produces crack networks that get structural epoxy or polyurea injection, not surface paint-over. A bad answer is "we just coat over it." For the broader failure pattern see why epoxy garage floors peel.
10. Are you insured, and is the crew verified through the Amazing Garage Floors network? Verified means the crew has been trained on the specific product system, audited on installation quality in the Central Florida market, and stands behind the same warranty as every other Amazing Garage Floors installer. A bad answer is vague insurance language with no documentation, or a company name that does not appear in any installer directory.

What the right answers sound like together

A good Orlando installer will connect the answers. They will tell you that your Baldwin Park slab needs a moisture vapor test because of the high water table under the engineered fill, that the hairline settlement crack near the door threshold gets injected before the diamond grind, that the grind is going to take a coarser grit because there is residual sealer they need to remove first, and that the humidity-cured polyaspartic topcoat is what lets them finish in a day and hand you a 15 year warranty. They sound like someone who has installed in this metro hundreds of times because they have.

What a bad installer sounds like

The bad version answers each question in isolation and avoids specifics. "We grind." "Our epoxy is industrial." "Warranty covers the floor." "Cure is fast." Follow-ups make the answers vaguer rather than more specific. That is the conversation to walk away from before signing.

The specific Orlando context to test for

The installer should know what makes Central Florida concrete different from a generic suburban slab. Test for that with a few local follow-ups.

• Historic slabs in Thornton Park, College Park, and the Mills 50 corridor often sit on filled wetland with ongoing settlement patterns and elevated vapor emission. The installer should describe both as routine, not as exceptions.
• Master-planned communities in Lake Nona, Baldwin Park, and Dr Phillips were built on engineered fill with modern vapor barriers, but the regional water table still drives upward vapor migration that the installer should plan for.
• Daily summer convective storms force installation scheduling around the 3 to 6 PM window. A crew that does not name the pattern has probably not worked through a Central Florida summer.
• South- and east-facing garage doors take direct Florida UV through every open-door cycle. The topcoat has to be aliphatic to hold its film integrity through that exposure.

What to ask if the installer pushes a DIY-equivalent product

Some installers in the Orlando market bid low by quoting a thin water-based coating that is closer to a hardware-store DIY kit than a professional system. If the number seems low and the topcoat chemistry is vague, ask the question covered in our breakdown of DIY epoxy garage floor kits. A low-mil water-based product on an Orlando slab with elevated vapor emission is a coating that will bubble off within the first wet season regardless of who applies it.
