Choosing a garage floor coating isn’t just about appearance. The questions you ask during the estimating process can determine whether your floor lasts for decades, or starts failing far sooner than expected.
Below is a simple “installer interview” homeowners can use to separate shortcuts from craftsmanship before making a decision.
Can you install a 1-day polyurea-polyaspartic coating?
A trustworthy answer sounds like this: “Yes, but we’d rather do it right.”
Most concrete slabs contain more than 1% moisture. Installing a 1-day system directly to concrete without proper moisture mitigation can trap that moisture beneath the coating, increasing the risk of blistering or peeling. While faster installs use less material and labor, professional installers test moisture levels first and recommend a 2-day system when conditions call for it.
What types of coatings do you use?
Quality garage floor coatings rely on multiple coating technologies, not a single product. Industrial-grade epoxies, polyurethanes, and polyurea-polyaspartics each serve a specific role. Epoxy provides strong adhesion and builds thickness, while polyurea-polyaspartics deliver UV stability, chemical resistance, and durability as color and topcoats. The right combination depends on your concrete and environment.
How do you prepare the concrete?
This question reveals a lot about an installer’s experience. Proper preparation requires professional diamond grinding to achieve the correct concrete surface profile (CSP). Cleaning alone, or acid etching, is not sufficient for long-term adhesion. Skilled installers understand that surface prep is the foundation of a successful garage floor coating.
Are your coating products zero- or low-VOC?
Today’s premium coatings are designed with indoor air quality in mind. Unfortunately, some contractors still use older products with high levels of volatile organic compounds (VOCs). A professional installer should be able to provide technical data sheets that clearly outline VOC ratings and product safety details.
Can your coatings be applied in extreme heat?
High temperatures affect curing and adhesion. An experienced installation team understands how to choose coating materials designed to perform in extreme heat and apply them correctly year-round.
What does your warranty cover?
Warranties should be clear and specific, not vague promises. Ask what’s covered, what’s excluded, and how workmanship and materials are protected over time.
