Clear Epoxy vs Concrete Sealer: Which Finish Is Best for Your Floor?
When it comes to protecting or enhancing a concrete floor, two options often come up: concrete sealer and clear epoxy coating. Both aim to protect and beautify concrete, but their performance differs depending on use and environment.
Important: For garages or outdoor areas, neither epoxy nor sealer is suitable. For these conditions, the polyaspartic coating with vinyl flakes remains the most durable and easy-to-maintain option, especially in Canadian climates.
What Is a Concrete Sealer?
A concrete sealer is a liquid applied to the surface to protect concrete from moisture, stains, and wear.
It acts as an invisible barrier that keeps water, salt, and oil from penetrating the concrete.
Benefits of a Concrete Sealer
- Adequate protection against freeze-thaw cycles, salt, and liquids
- Easy maintenance and quick cleaning
- Affordable and fast to apply
- Keeps a natural matte look
Limitations
- Moderate durability (about 2 to 5 years)
- Matte or semi-gloss finish only.
- Doesn’t correct cracks or imperfections
- Requires periodic reapplication
A sealer is a solid choice for basic, low-cost protection for indoor concrete with minimal exposure.
What Is a Clear Epoxy Coating?
A clear epoxy coating is a resin-based product applied in multiple layers.
It creates a smooth, glossy, and durable finish, often used in basements, workshops, and commercial spaces.
Benefits of Clear Epoxy
- Long-lasting (10 to 15 years when properly installed)
- High resistance to chemicals, oils, and abrasion
- Premium glossy appearance
- Option to add decorative flakes or non-slip texture
Limitations
- Higher upfront cost
- Technical application requiring proper surface prep
- Not UV-resistant, so not ideal outdoors
Epoxy is perfect for interior concrete floors where you want a durable and elegant finish.

FAQ
What’s the difference between a sealer and epoxy?
A sealer protects the surface, while epoxy creates a hard, decorative layer over it.
Can clear epoxy be used outdoors?
No. It’s not UV-resistant. Use a specialized exterior coating instead.
How much does clear epoxy cost?
Typically, the cost is between 12 and 15 CAD per square foot.
Does a sealer make concrete slippery?
It can. Adding a non-slip additive improves traction.
Summary
- Concrete sealer = affordable, basic protection
- Epoxy coating = premium interior finish
- Polyaspartic = the most durable garage solution in Canada
