What questions should I ask a garage floor coating installer in Lenexa before signing?

Lenexa property owners getting bids on a garage floor coating face the same problem every Johnson County homeowner faces: the bids look similar on paper, the marketing photographs look identical, and the actual differences between installers live in the technical specifications and the prep scope that the salesperson does not always volunteer. Across the city, from the Old Town Lenexa historic corridor to the rapidly growing west-side master-planned communities of Falcon Ridge, Stonebridge, and Greystone Hill, the way to separate a serious installer from a sales operation is by asking ten specific questions during the on-site assessment and listening carefully to what comes back. Here is what to ask and what the right answers sound like.

The 10 Questions, in Order

The order matters because each answer informs the next. Print this section, take it to the assessment, and write down what the installer says.

1. What diamond grind grit are you using on my slab, and how many passes? A serious installer for an Old Town Lenexa slab or a mid-century Quivira Hills slab knows the answer cold: typically a 30 or 40 grit metal bond for the initial cut, stepped up to 80 or 120 for the finish, multiple passes documented to ICRI surface profile standards. If the answer is "we acid etch" or "we pressure wash and apply primer," the prep is not adequate for a Johnson County slab that has been through decades of clay cycling.
2. How will you moisture test my slab before the basecoat goes down? A calcium chloride test or a relative humidity probe with documented results is the right answer. "We have not had problems with moisture" is not a test result. Lenexa slabs vary by neighborhood, by drainage conditions, and by construction era, and the test is the only honest way to know what the slab is doing before the coating commits.
3. What is the basecoat chemistry, and is it a high-solids two-part epoxy? The installer should name the product, confirm the percent solids, and confirm it is a two-part system mixed on site to the manufacturer specification. A vague "commercial-grade epoxy" answer with no product name is a red flag.
4. Is the topcoat a polyaspartic, and specifically an aliphatic UV-stable polyaspartic? The two terms you want to hear are polyaspartic and aliphatic. Lenexa garage doors facing south or west across the City of Festivals admit hours of direct Kansas afternoon sun in summer. An aromatic topcoat yellows under that exposure within the first year. If the installer cannot confirm the chemistry as aliphatic polyaspartic, the topcoat is the wrong layer for this market.
5. Will my install actually be completed in a single day? A standard residential install in a two or three-car attached garage in Quivira Hills or a newer Stonebridge build should complete in one working day from arrival through final topcoat. If the installer wants three days, the chemistry is probably standard epoxy with a long cure window.
6. What is the cure schedule before I can walk on it and before I can park on it? Walk-ready the next morning, vehicle-ready in approximately 72 hours is the polyaspartic-system answer. If the answer is one to two weeks before vehicle use, the topcoat is not polyaspartic.
7. What are the actual terms of the warranty, and what is excluded? The Amazing Garage Floors Limited 15 Year Warranty covers adhesion failure, peeling, and delamination attributable to materials or installation. Read what is excluded. Warranties that exclude hot tire pickup, UV yellowing, or freeze-thaw damage are warranties on chemistry that fails to those mechanisms.
8. How will you repair the existing cracks in my slab? A 1970s slab in Quivira Hills or a 2010s slab in Stonebridge will have different crack patterns, but both will have something. The right answer names structural epoxy injection for hairline cracks, polyurea for cracks with continued movement, and structural patching compound for spalled areas. "Filler caulk" is not a structural answer.
9. Who is actually installing the floor, your in-house crew or a sub? A serious local installer has a verified crew that does the work directly. The salesperson at the assessment should identify the lead installer for the day of the job. Hedged answers or routing through a different company create accountability gaps if the floor develops problems later.
10. Are you insured, and are your installers verified through the brand network? General liability insurance and workers' compensation should be active, and the installer should produce a certificate on request. Verified installer status confirms the crew has completed the documented training protocol and works to the specification the warranty depends on.

Why These Answers Matter on a Lenexa Slab Specifically

The reason these questions matter in Lenexa is that the local concrete reality punishes shortcuts in ways that show up two to three years out. Johnson County's expansive clay subsoil cycles seasonally under every garage in the city, from the original Santa Fe Trail era residential stock in Old Town Lenexa to the engineered-fill builds along Renner Road and the 95th and Pflumm corridor. The 30 or more freeze-thaw events per Lenexa winter, with January lows averaging around 22 degrees, stress any moisture in the slab. Road salt brine deposited from every February drive on I-435, K-7, 87th Street Parkway, 95th Street, and Pflumm Road penetrates uncoated concrete and degrades low-grade coatings simultaneously.

Older slabs in Quivira Hills, Cedar Crest, and Pinehurst have been through four or five decades of that cycling, so the prep scope is typically larger. The crack patterns are mature, the surface laitance is more weathered. Newer west-side engineered-fill slabs in Falcon Ridge, Greystone Hill, and Stonebridge are more uniform, but they still need diamond-grind prep and crack repair because seasonal clay cycling continues regardless of the fill underneath. The questions above are how you confirm the installer understands which scope applies to your specific slab.

What to Watch For During the Assessment

The assessment is the audition. How a verified installer walks your garage tells you almost as much as the answers to the question list.

• Does the crew member actually walk the full slab, looking at crack patterns, the door threshold, the control joints, and any moisture indicators? Or do they spend ninety seconds inside and the rest of the visit selling at the kitchen table?
• Do they bring physical sample boards into your actual garage to evaluate color blends in your actual lighting? Sample evaluation should happen in the space where the floor will live, not from a screen or a catalog.
• Do they identify specific prep work needed on your slab and explain why? Or do they say everything looks fine and quote a single round number with no detail?
• Do they answer technical questions about chemistry and warranty specifics directly, or do they redirect to closing pressure and a today-only urgency tactic?

The Bid Comparison Step

If you have three bids in hand and they look similar on the surface, the technical specification is where the actual difference lives. Two installers can quote in the same range and deliver wildly different floors because the product systems, the prep scopes, and the warranty terms are not the same. A floor that comes in at a lower number but uses an aromatic topcoat is a floor that yellows in the first Kansas summer. A floor that skips the moisture test is a floor that develops bubbling and peeling as soon as the first wet spring drives vapor pressure through an unprotected slab.

The honest way to compare is to lay the ten answers side by side. The installer who answers all ten directly with specifics is the installer who is going to deliver a floor that holds through Johnson County's full annual cycle.
