Garage Floor Coating in Ontario
Garage floor coating covers a range of products applied over concrete to protect it and clean up its look: epoxy, polyaspartic, polyurea, and various hybrid systems. The better installers grind or shot-blast the concrete first to open up the surface, patch cracks and pitting, then build up a base coat, a decorative flake or quartz layer if that's part of the package, and a topcoat that handles hot tires, salt, and road grit without peeling. We've listed 89 companies doing this work across Ontario, ranging from small crews running one or two jobs a week to larger operations with multiple install teams.
What to look for before you hire
The prep work matters more than the brand of coating. Ask what surface profile they aim for and whether they mechanically grind (diamond grinding or shot blasting) rather than just acid-etch, which is a weaker method that a lot of cheaper crews still use. Ask about moisture testing on the slab, since trapped moisture is the main reason coatings bubble or delaminate later. Get clarity on cure times before you can drive or walk on the floor, what the warranty actually covers (peeling and delamination versus just fading), and whether the crew that shows up is direct employees or subcontracted labor.

Common questions about garage floor coating
- How much does garage floor coating cost in Ontario?
- Most single or double car garages run somewhere between roughly $1,500 and $5,000 depending on square footage, the coating system used, and how much crack repair or concrete prep is needed. Polyaspartic and polyurea systems generally cost more per square foot than basic epoxy but cure faster and hold up better to UV and hot tires.
- How often does a garage floor coating need to be redone?
- A properly installed multi-coat system with a quality topcoat can last 10 to 20 years with normal use. Thin, single-coat DIY-style jobs or ones done without grinding the concrete often show peeling or flaking within a few years, especially where snow-melting road salt gets tracked in all winter.
- What should I expect during the install?
- Expect the garage cleared out completely, one to two days for grinding and prep, and another one to three days for coats to go down and cure, depending on the system. Polyaspartic jobs can sometimes be walked on the same day; epoxy usually needs 24 to 72 hours before foot traffic and up to a week before parking a vehicle on it.
- How can I judge the quality of a finished floor?
- Look at the edges near the garage door and walls for clean, even lines, check that the flake or quartz broadcast is consistent rather than patchy, and ask to see photos of a job from a year or two back rather than a brand-new install, since that shows how the coating actually wears.
