Does a Garage Floor Coating Smell? Odor, Safety, Pets and Rooms Over the Garage

Quick answer: Yes, there is some odor while a floor coating is being applied. The crew ventilates the space as they work, and the smell fades as the floor cures. Once it's cured, the coating is safe for indoor use. The main thing to plan for is keeping people and pets out of the space during the install and while it cures.

For a lot of families, the smell is the question that comes right after the price. You might have a bedroom over the garage, a baby napping down the hall, a dog who goes everywhere you do, or someone in the house who's sensitive to strong odors. Those are fair things to think about before install day.

Here's what to expect, how long it lasts, and simple ways to plan your day around it.

Why there's an odor at all

A professional floor coating is made of two parts that are mixed together on site. Once mixed, they react and harden into a solid floor. Like paint, stain and many other building products, coatings give off some odor while they're being applied and while that reaction finishes.

The EPA notes that paints, varnishes and similar products can release compounds into the air, and its basic advice is simple: increase ventilation and follow the product's label directions (EPA: volatile organic compounds and indoor air quality). That's exactly how our crew works. The space is ventilated while the coating goes down.

What install day feels like

Here's how the day usually goes, and where odor fits in:

• Grinding and repairs come first. This part is noisy but doesn't involve the coating yet. The concrete is diamond-ground and cracks are repaired.
• The base coat and flake go down. This is when you'll start to notice an odor.
• The topcoat goes on last. A clear, UV-stable polyaspartic topcoat seals everything in. Odor is still present while it's applied. Watch it happen in our top coat day video.
• The floor cures. The odor fades as the coating cures.

Most residential projects are completed in a single visit. For the full step-by-step, read what to expect when your garage floor gets coated.

Simple ways to plan around it

A little planning goes a long way. These steps help on install day:

• Close the door between the garage and the house. Keep it shut during the install and while the floor cures. A rolled towel at the bottom of the door helps.
• Think about rooms over or next to the garage. If there's a bedroom above, a nursery nearby, or someone who works from a room next to the garage, plan for them to spend the day in another part of the house or out running errands.
• Make a plan for pets. Keep dogs and cats out of the garage during the install and while it cures. Curious paws and fresh coating don't mix.
• Keep kids out, too. Same rule: no one walks on the floor until it's ready.
• Tell us about anyone who's sensitive to odors. Bring it up at your estimate so we can talk through timing and how the day will go.

Basements and spaces inside the house

Basements are a bit different from garages because they're connected to the main living space and don't have a big overhead door. If you're coating a basement floor, plan ahead for the household to be away from the space during the install, and mention any concerns during the walkthrough. Our basement floor coating guide covers what else to know before a basement install.

Once it's cured: safe for everyday living

After the floor cures, it's simply your floor. Our coatings are safe for indoor use once cured, which is why they work in garages, basements and other living spaces.

A coated floor is also much easier to keep clean day to day. Bare concrete makes dust and soaks up stains and spills. A sealed, non-porous floor stops concrete dust and keeps spills on top where they wipe up. Joe talks about the difference in why your garage still feels dirty after cleaning.

When you can use the space again

On our floors, here's the timeline to plan around:

• First 24 hours: stay off the floor completely.
• After about 24 hours: light foot traffic is fine.
• After about 48 hours: drive and park on it.

Pets and kids follow the same timeline. Once it's ready for feet, it's ready for paws.

Questions worth asking any installer

Whoever you hire, it's fair to ask how they handle odor and safety. Good answers are specific. Here are a few questions to bring to every estimate:

• How will you ventilate the space while the coating goes down?
• Is the product safe for indoor use once it's cured?
• How long should people and pets stay off the floor?
• When can I walk on it, and when can I park on it?
• What should I do with the door between the garage and the house?
• Is there anything I should move out of the garage besides what's on the floor?

If an installer can't answer these clearly, that tells you something. For more questions to line up quotes side by side, see how to compare garage floor coating quotes.
