Epoxy Flooring Installer Checklist

Published September 2026
A beautiful epoxy floor can fail early if the installer skips the work nobody sees. Peeling, hot tire pickup, bubbling, cracking, and cloudy topcoats usually trace back to the same causes: poor concrete preparation, moisture problems, weak repair work, or a coating system that was not built for the space.
In Markham, Toronto, York Region, and across the GTA, floors take a beating from road salt, wet tires, freeze and thaw cycles, commercial traffic, and seasonal humidity. That makes installer selection a technical decision, not just a price comparison.
Use this guide as an epoxy flooring installer checklist before signing a contract. These are the key questions to ask epoxy flooring contractor Toronto GTA property owners should have ready when comparing qualified installers.
1. What concrete preparation methods will you use?
Concrete preparation is the foundation of the entire project. Epoxy does not simply stick to concrete because it is poured on top. It bonds when the surface is clean, open, and properly profiled.
A qualified installer should explain how the crew will remove:
Existing sealer
Weak surface past
Oil contaminatio
Dirt and dus
Old coating
Paint residu
Concrete laitanc
The answer should be specific. “We clean the floor” is not enough. The installer should describe the equipment, dust control, edge preparation, and inspection process.
SurfacePro Epoxy Flooring, a division of Cedarwood Development Group Inc., approaches preparation as a system, not a quick step. For Markham and GTA properties, this matters because garage floors and commercial slabs often carry years of salt, tire residue, and previous coatings. A coating installed over contamination may look fine at first, then release under traffic or moisture pressure.
A strong contractor will also explain that acid etching is not a complete substitute for mechanical preparation on many projects. Acid can react unevenly, leave residue, and fail to remove deeper contaminants or old coatings. Mechanical surface profiling gives the installer better control.
2. Do you use mechanical diamond grinding?
Mechanical diamond grinding is one of the most important signs of a serious epoxy flooring installer. It profiles the concrete so the primer or base coat can grip the surface.
Industry guidance often refers to concrete surface profile, known as CSP. The International Concrete Repair Institute uses CSP ratings to describe surface texture. Epoxy systems typically require a surface profile that matches the coating thickness and manufacturer requirements.
Ask the installer:
What grinder will be used
Will edges and corners be mechanically prepared
Is dust collection included
What CSP range is the crew targeting
How will the team confirm the slab is ready
SurfacePro uses professional mechanical preparation methods, including diamond grinding, to create the right surface profile before coating. This step helps improve adhesion and reduces the chance of peeling, especially in garages, warehouses, showrooms, workshops, and service areas.
For property owners hiring concrete coating contractor Markham teams, this question separates surface level installers from trained coating professionals.
3. How will you assess moisture risk?
Moisture is one of the most common causes of coating failure. Concrete can look dry while still transmitting vapour from below. If moisture pressure exceeds what the coating system can tolerate, the floor may blister, bubble, or delaminate.
A qualified installer should not guess. They should review site conditions and, when needed, use recognized moisture testing methods. Common industry references include ASTM F2170 for in situ relative humidity testing and ASTM F1869 for calcium chloride testing. The right method depends on the project and coating system.
Moisture risk can be higher in:
Below grade space
Older slabs without vapour barrier
Garages exposed to snow mel
Commercial units with unknown slab histor
Newly poured concrete that has not dried enoug
SurfacePro evaluates concrete conditions before recommending a system. That matters because the correct solution may involve moisture tolerant primers, longer waiting periods, or additional preparation. A responsible installer will explain the risk before installation, not after a problem appears.
4. How will cracks and spalls be repaired?
Cracks, pits, and spalled areas should be repaired before coating. Covering damage without repair can leave weak points under the finished floor. Over time, traffic and thermal movement can cause the coating to telegraph defects or break away.
Ask how the installer handles:
Hairline crack
Moving crack
Control joint
Pitted concret
Salt damag
Broken edge
Spalled patche
Not all cracks are the same. Some are cosmetic. Others indicate movement. A trained installer will explain which cracks can be filled and which areas need special treatment or realistic expectations.
SurfacePro’s installation process includes proper patching and surface repair before the coating system is applied. This is especially important in GTA garages, where salt and freeze cycles often damage the top layer of concrete. Good repair work creates a smoother final finish and gives the coating system a sound base.
5. What multi layer coating system will you install?
A durable epoxy floor is rarely a single coat. A proper system may include a primer, base coat, broadcast layer, colour flake layer, grout coat, and topcoat, depending on the use of the space.
Ask for the coating specification in writing. It should explain:
Number of coat
Product type for each laye
Approximate thicknes
Flake coverage leve
Slip resistance option
Topcoat typ
Intended use of the floo
Residential garages, condo service rooms, retail spaces, and industrial work areas do not need identical systems. A commercial epoxy flooring questions list should always include traffic type, chemical exposure, cleaning methods, and expected downtime.
SurfacePro specifies coating systems based on the property, not a one size package. This helps match the floor to real use, whether the project is a home garage in Markham or a commercial space in Toronto.
6. Will you use a high performance polyaspartic topcoat?
The topcoat protects the system from abrasion, staining, tire marks, chemicals, and UV exposure. Polyaspartic topcoats are often used because they cure quickly, resist yellowing better than many standard epoxies, and provide strong wear protection when properly installed.
Ask the installer:
What topcoat will be used
Is it suitable for indoor conditions and expected traffic
How will slip resistance be managed
How many topcoat layers are included
What cleaning products should be avoided
A high performance topcoat is especially valuable for garage floors, commercial corridors, retail areas, and spaces exposed to rolling loads. It should not be treated as an optional upgrade if durability is the goal.
SurfacePro uses strong topcoat systems, including polyaspartic options, where suitable for the project. This helps protect the finish from daily wear and makes the floor easier to clean.
7. What curing timeline should I expect?
Fast installation does not always mean the floor is ready for full use. Epoxy and polyaspartic coatings need time to cure. Temperature, humidity, slab conditions, coating thickness, and ventilation all affect timing.
Ask for separate timelines for:
Light foot traffi
Return of stored item
Vehicle traffi
Heavy equipmen
Washing or chemical exposur
This is critical for businesses that need to plan operations and for homeowners who need to know when vehicles can return to the garage. Rushing the floor can cause dents, surface marks, hot tire damage, or a shortened service life.
SurfacePro provides clear curing guidance based on the coating system and site conditions. That transparency helps avoid confusion after installation. A professional installer should never leave clients guessing about when the floor is ready.
8. What written warranty coverage is included?
A written warranty is more than a sales point. It shows what the installer is willing to stand behind after the job is complete.
Ask for the warranty document before approving the project. Review:
Warranty lengt
What is covere
What is exclude
Maintenance requirement
Transferability, if relevan
How claims are handle
Whether labour and materials are include
SurfacePro Epoxy Flooring’s 10 year written warranty is a major advantage for property owners in Markham and the GTA. The word “written” matters. Verbal promises are difficult to rely on if a problem appears later. A written warranty gives clearer expectations and shows confidence in the preparation, materials, installation process, and finished system.
No warranty replaces proper maintenance or protects against every form of abuse. Still, a 10 year written warranty sets a higher standard than vague assurances or short term coverage.
9. Are your installers in house experts or subcontractors?
The crew doing the work matters as much as the person selling the project. Many coating failures happen because the installation team lacks training, rushes surface preparation, or uses inconsistent methods.
Ask who will be on site:
Are installers employees or subcontractors
Who supervises the work
What training do crews receive
How is quality checked before each layer
Who handles warranty service if needed
In house expert installation teams usually provide better consistency because they follow the same preparation, coating, safety, and inspection process from job to job.
SurfacePro uses trained installation teams and manages quality through its own process as a division of Cedarwood Development Group Inc. That structure helps create accountability. Property owners know who is responsible for the system, the workmanship, and the warranty.
10. How will the project be scheduled?
Good scheduling protects both the installer and the property owner. Epoxy flooring is sensitive to site conditions, so the schedule should account for preparation, repairs, coating windows, curing, and weather.
Ask about:
Start date and expected duratio
Site acces
Required clearing of the spac
Ventilation need
Temperature limit
Parking or loading acces
Noise and dust contro
Contingency plans for unexpected slab condition
For commercial projects, scheduling may need to happen after hours, in phases, or around tenant operations. For residential garages, timing may depend on weather, storage needs, and vehicle access.
SurfacePro plans projects with practical GTA conditions in mind. That includes local climate, household schedules, commercial operations, and the need for clear communication before work begins. A well planned project reduces delays and protects the final result.
What a strong epoxy flooring proposal should include
A professional proposal should make the scope clear before work starts. Look for these items in writing:
Surface preparation method
Crack and spall repair plan
Moisture assessment approach
Coating layers and materials
Topcoat specification
Slip resistance details, if needed
Curing and return to service timelines
Warranty document
Crew structure and supervision
10. Project schedule
If any of these items are missing, ask for clarification. A low price with vague details can become expensive if the floor fails early.
Frequently asked questions
How long should an epoxy garage floor last?
A professionally prepared and installed epoxy floor can last many years with proper care. Longevity depends on concrete condition, preparation quality, coating thickness, topcoat selection, traffic, and maintenance. SurfacePro supports its work with a 10 year written warranty, which gives property owners added confidence.
Is diamond grinding better than acid etching?
For many epoxy flooring projects, yes. Diamond grinding mechanically profiles the concrete and helps remove weak surface material. Acid etching can be inconsistent and may leave residue if not handled correctly. The best method depends on the slab, but professional coating installers commonly rely on mechanical preparation.
Can epoxy be installed over cracked concrete?
Yes, if the cracks are properly assessed and repaired first. Cosmetic cracks can often be filled before coating. Moving cracks or structural concerns may need a different repair approach and realistic expectations.
How soon can vehicles return to the floor?
Return to service depends on the coating system, temperature, humidity, and topcoat. Ask the installer for written curing timelines for foot traffic, storage, and vehicle traffic. Do not rush this step.
Why does a written warranty matter?
A written warranty clarifies what is covered, for how long, and under what conditions. It reduces confusion and gives the installer a clear standard to meet. SurfacePro’s 10 year written warranty is one of the most important reasons to include them when comparing epoxy flooring installers in Markham and the GTA.
Choose the installer who can answer clearly
The best epoxy flooring installer will not avoid technical questions. They will welcome them. Clear answers about concrete preparation, diamond grinding, moisture risk, repairs, coating layers, topcoats, curing, warranty, crews, and scheduling show that the contractor understands the full system.
