The 7 checks you must make on site
Below are seven numbered decision nodes. Each item tells you what to inspect, the exact questions to ask a contractor, and the evidence you should require before signing a quote.
1. Slab condition audit: check cracking, contaminants, and prior treatments
Begin with a slab audit. Have the contractor walk the floor with you and point out visible issues: mapped cracks, spalled areas, laitance, joints, and any signs of previous sealers or curing compounds. A proper audit will include a description of the substrate integrity and any repairs required before coating. Choosing a system without this step risks a mismatch between product and substrate, which is a common cause of failures noted by professional specifiers and contractors.
For a commercial specification approach that places the slab first, see the practical guide to specifying floors.

2. Traffic, loads and chemical exposure: match chemistry to use
Record the expected daily use: light foot traffic, workshop use, parked vehicles, pallet jack or forklift traffic, and any point loads from racking. Note chemical exposures such as motor oil, gasoline, battery electrolyte, solvents, detergents, or cleaning acids. These variables determine resin chemistry, recommended film thickness, and whether a decorative flake system, a heavy-duty epoxy, or a different product family is appropriate.
Selection tips that place traffic and chemical exposure among primary inputs are explained in the epoxy resin flooring selection checklist; a floor used by pallet jacks needs a different specification than a showroom or a basement.

3. Moisture and vapour testing: don’t trust a visual inspection
Never accept a verbal assurance that the slab is "dry." Ask for objective moisture testing results. The contractor should perform and provide one of these tests: in situ relative humidity tests, a calcium chloride vapour emission test, or another industry-accepted method. Moisture vapour drive or residual slab moisture is a leading cause of adhesion failure. Professional checklists emphasise testing because simple sweeping or mopping will not detect trapped moisture or curing compounds that block bonding.
For why moisture testing matters and the tests commonly used, see the quality inspector checklist that warns against visual-only prep.

4. Surface preparation: confirm diamond grinding, crack repair and cleaning
Ask for the specific prep method in the quote. Acceptable preparation includes mechanical profiling such as diamond grinding or shot blasting to achieve a clean, sound surface profile, plus targeted crack repair or patching with compatible cementitious products. Contractors should explain how they will remove oils, adhesives, and dust prior to priming. Sweeping and mopping alone are not sufficient to ensure adhesion. Request to see or receive photos or short video clips of the prepared slab before any primer is applied.
Industry guidance stresses mechanical profiling and documented repair over informal cleaning; for more on appropriate prep methods see this selection guide.

5. System chemistry and layer thickness: confirm primer, body coat and topcoat
Good specifications are multi-layer. A primer penetrates and bonds to the substrate, body coats build film thickness and impact resistance, and a topcoat provides abrasion and chemical resistance. Ask the contractor to list each product to be used, intended dry film thickness per coat, and total expected mil thickness. If the project is outdoors or exposed to sunlight, discuss alternatives: polyaspartic or polyurea topcoats often offer greater UV stability and faster return-to-service, while epoxy topcoats remain a durable interior choice. When considering alternatives, check the summary comparison on polyaspartic versus epoxy chemistry.

6. Finish, texture and slip resistance: pick a practical surface
Select a finish that balances aesthetics and safety. Flake systems hide imperfections and provide a textured finish if broadcasted for traction. Metallic epoxy creates a high-gloss showroom effect but can be smoother unless an anti-slip additive is incorporated. For garages and commercial entrances where road salt, water, and oil are present, request an anti-slip broadcast or textured topcoat and a finish that is easy to clean. Your contractor should explain maintenance needs for each finish choice.
JLN Epoxy documents available finish options and explains functional tradeoffs between gloss, cleaning, and traction on its service pages.

7. Contractor vetting, documentation and warranty: ask for proof
Before you commit, require the contractor to provide: before-and-after photos that include surface-prep stages, written moisture test results, a written scope listing product names and coat thicknesses, references for similar GTA projects, and clear warranty terms tied to the completed scope. Prefer owner-led or owner-supervised teams that offer documented quality control steps. A lack of documentation, vague warranty language, or refusal to show prep photos are valid reasons to pause.
The professional inspector checklist recommends documented evidence of prep and testing as essential steps contractors should show during quoting and execution.

Epoxy versus polyaspartic and polyurea: quick differences to check
When contractors propose alternatives, compare these practical differences. Polyaspartic and polyurea products cure faster and are often more UV stable, which makes them attractive for outdoor or sun-exposed areas. Epoxy systems remain a common interior choice for garages, basements, and warehouses because of cost-to-performance balance and excellent chemical resistance when specified correctly. Ask whether a proposed polyaspartic or polyurea will require different prep, and whether the warranty reflects the alternate chemistry.

Toronto and GTA considerations: salt, freeze‑thaw and basement moisture
Local conditions change the decision. Expect salt transfer from tires in winter to increase chemical and abrasion exposure in garage entrances. Freeze-thaw cycles may affect scheduling and require additional joint or crack repairs. Basements in older Toronto homes commonly exhibit higher slab moisture that must be tested and remediated prior to coating. Include these regional factors in your conversation with contractors and in the written scope.

Contractor interview script and three red flags to avoid
- Ask: "Can you show recent photos or a short video of the diamond grinding and repairs for a similar project?" Acceptable answer: time-stamped photos or a clear explanation of the prep steps. Red flag: refusal or only polished finished photos.
- Ask: "Can I see written moisture test results and the method used?" Acceptable answer: RH test or calcium chloride results with numbers and thresholds. Red flag: no testing or only a verbal 'dry' statement.
- Ask: "What products and total dry film thickness will you apply?" Acceptable answer: product names, coat-by-coat mils, and intended performance. Red flag: vague product descriptions or no thickness specified.
Decision criteria matrix: which system to prioritise
Use these rules to prioritise system families during quotes:
- Slab poor plus heavy industrial use: prioritise heavy-duty, thicker epoxy systems with cementitious patching and multiple body coats.
- Good slab plus domestic garage or basement: flake epoxy systems offer durability and low maintenance with a decorative finish.
- Showroom or feature interior: metallic epoxy or high-gloss systems, paired with appropriate topcoat and anti-slip options as needed.
- Outdoor or UV-exposed areas: consider polyaspartic or polyurea topcoats for UV stability and faster cure.
Expect most residential garages to be scheduled for 1 to 2 days of on-site work for grinding and coating, while larger commercial areas will require longer prep and staged curing. Your contractor should provide a project timeline with the quote.

Frequently asked questions
How long does epoxy floor installation take for a typical garage and for a commercial space?
Most residential garages can be completed in 1 to 2 days of on-site work for grinding, repairs, coating, and initial cure, while commercial projects vary by square footage and prep needs. A contractor should provide an explicit timeline with the quote.
How do I know if my concrete needs moisture remediation before coating?
Request written moisture testing. If relative humidity or vapour emission tests exceed manufacturer limits for the proposed system, remediation is necessary. Do not accept a visual-only assessment.
Is epoxy safe for a driveway or outdoor area in Toronto or should I choose polyaspartic?
For outdoor or sunlight-exposed surfaces, polyaspartic or polyurea topcoats are often recommended for better UV stability and faster cure. Epoxy can yellow or degrade under UV exposure, so discuss UV-rated topcoats if epoxy is proposed for an exterior application.
Can I expect the contractor to show before and after photos of surface preparation?
Yes. Ask for photos or short videos documenting mechanical prep, crack repair, and patching before primer is applied. Documentation of prep is a standard part of quality control and a strong indicator of a professional installation.
What warranty and maintenance items should be written into the quote?
The quote should include warranty terms that reference the exact scope, the products used, and any limitations. Also ask for a short maintenance guide covering cleaning products, recoat schedules, and what actions void the warranty.
