Questions That Separate Good Brisbane Epoxy Contractors from Bad Ones
Hiring an epoxy flooring contractor in Brisbane is a significant investment, and asking the right questions before committing can save you thousands in remediation costs if things go wrong. The questions below are designed to reveal the contractor’s expertise, professionalism, and commitment to quality — or expose the gaps that should send you looking elsewhere.
Question 1: What Is Your QBCC Licence Number?
This should be your very first question. In Queensland, any building work valued at $3,300 or more requires the contractor to hold a valid QBCC licence. Ask for the number and verify it online at the QBCC website. A legitimate contractor will provide their licence number immediately without hesitation.
What their answer tells you: A contractor who cannot provide a licence number, claims they do not need one, or gives you a number that does not verify correctly is either unlicensed (which is illegal for projects over $3,300) or dishonest. Either way, move on.
Question 2: What Specific Products Will You Use on My Floor?
Ask for specific brand names, product names, and product types. A professional contractor knows exactly what they are putting on your floor and can explain why they chose that particular system for your project.
What their answer tells you: Vague answers like “we use a premium two-pack epoxy” suggest the contractor either does not know their products well or does not want you comparing their materials with competitors. A confident answer naming specific manufacturer products (and offering to show you the technical data sheets) indicates expertise and transparency.
Question 3: How Do You Prepare the Concrete Surface?
The answer you want to hear involves diamond grinding with specific equipment to achieve a defined concrete surface profile (CSP-2 or CSP-3). If the answer is “acid etching” or “we give it a good clean and sand,” the preparation will likely be insufficient for a long-lasting result.
What their answer tells you: Proper preparation is the foundation of every successful epoxy floor. A contractor who invests in quality grinding equipment and talks knowledgeably about surface profiles understands what makes floors last in Brisbane’s demanding climate.
Question 4: How Many Coats Are Included, and What Is the Total Thickness?
A professional system typically includes a primer, base coat (or coats), decorative elements (flakes, metallic pigments), and a clear topcoat. The total dry film thickness should be at least 300 to 500 microns for a residential system and more for commercial applications.
What their answer tells you: If the contractor cannot specify the number of coats and approximate total thickness, they may not be providing a complete system. Some budget operators apply a single thin coat that looks adequate initially but wears through quickly.
Question 5: What Type of Topcoat Do You Apply, and Is It UV-Stable?
In Brisbane, UV stability is not optional — it is essential. The topcoat should be polyurethane, polyaspartic, or another UV-stable clear coat that protects the decorative epoxy layer beneath from yellowing and chalking in Queensland’s intense sunlight.
What their answer tells you: A contractor who includes a UV-stable topcoat as standard understands Brisbane’s climate and its impact on epoxy flooring. One who does not mention it or offers it only as an expensive add-on may not be providing a system designed for local conditions.
Question 6: Can I See Examples of Your Previous Work in Brisbane?
Ask for photos and ideally references from completed projects in Brisbane. The best evidence is projects completed 2 to 3 years ago that demonstrate how the floor has held up over time, not just freshly completed installations.
What their answer tells you: An experienced contractor has an extensive portfolio and happy customers willing to provide references. A contractor who cannot show previous work or can only show very recent projects may lack the track record to give you confidence. See our contractor selection guide for more evaluation criteria.
Question 7: What Does Your Warranty Cover, and What Does It Exclude?
Ask for specific details about warranty coverage, not just the duration. A 10-year warranty that excludes adhesion failure, hot tyre pickup, and chemical damage is less valuable than a 5-year warranty that covers everything.
What their answer tells you: A contractor who can clearly articulate their warranty terms — what is covered, what is excluded, and how to make a claim — stands behind their work. Vague warranty promises suggest the contractor either has not thought about it or does not intend to honour claims.
Question 8: Do You Test for Moisture in the Concrete Before Starting?
Moisture is one of the most common causes of epoxy failure in Brisbane. Professional contractors test for moisture in the concrete slab before beginning any coating work. The answer should describe a specific testing method (calcium chloride test, relative humidity probe, or at minimum a plastic sheet test).
What their answer tells you: Skipping moisture testing in Brisbane’s climate is a gamble with your investment. A contractor who routinely tests for moisture understands the local conditions and takes steps to ensure long-term performance.
Question 9: What Happens If Weather Delays the Installation?
Brisbane’s weather can change rapidly, particularly during the warmer months. A professional contractor has a clear plan for weather-related delays rather than pushing ahead in unsuitable conditions.
What their answer tells you: The right answer is that they monitor conditions and will postpone if temperature or humidity falls outside acceptable ranges. A contractor who says weather does not matter or that they work regardless of conditions is either inexperienced or willing to compromise quality to keep their schedule.
Question 10: What Is Your Payment Schedule?
Industry standard for Brisbane residential epoxy work is a 10 to 20% deposit with the balance due on completion. Be wary of contractors demanding large upfront payments or full payment before the job is finished.
What their answer tells you: A reasonable payment schedule demonstrates confidence in their ability to deliver satisfactory work. Contractors who demand most of the payment upfront may be cash-flow constrained or less motivated to deliver quality after receiving payment.

Frequently Asked Questions
Is it rude to ask contractors so many questions?
Not at all. Professional contractors welcome informed customers because it leads to better communication, clearer expectations, and smoother projects. A contractor who is annoyed by reasonable questions is not one you want working on your home. The best contractors enjoy discussing their craft and demonstrating their expertise.
What if different contractors give me contradictory answers?
This happens frequently and is actually valuable information. If three contractors explain something differently, research the topic or ask each contractor to explain why their approach differs. The differences often reveal which contractors truly understand the science and craft of epoxy flooring versus those repeating sales talking points.
Should I ask these questions by phone or during a site visit?
Ideally during a site visit. A face-to-face conversation while looking at your actual floor allows the contractor to give specific, relevant answers rather than generic responses. It also gives you the opportunity to gauge their professionalism, communication style, and attention to detail in person.
