Can you epoxy garage in winter?

Epoxy floors are one of the most durable surfaces available for a garage floor. They can be applied to concrete, asphalt, and other surfaces, but they will only perform as intended when applied at temperatures above 50 degrees Fahrenheit.

When you install floor coating in winter, the curing process takes longer than usual because epoxy does not cure well at low temperatures. The process will take about three days if it’s properly done.

Curing refers to the chemical reaction that occurs between two compounds that are joined together by heat or pressure (or both). This reaction results in a strong bond between these compounds so that they cannot be separated without destroying them both.

If you apply too much pressure on an epoxy without enough time for curing, you could end up with cracks appearing on your newly finished garage floor – which is why it’s very important for homeowners to understand how long does it take for garage floor epoxy to cure before applying their own coating onto their home’s concrete surface!

What temperature can you epoxy a garage floor?

The temperature should be between 50 and 90 degrees. No rain is forecast for at least 48 hours after the epoxy has been applied to your garage floor.

The floor should be completely dry before starting, and you should follow the directions on your epoxy can closely when it comes to mixing ratios, thin layers, etc.

How do you epoxy in winter?

You can use a heat gun, hairdryer, or hot water heater to warm the epoxy. These methods are great when you have access to electricity and want to keep your garage warm during the winter.

If you don’t have access to an outlet or do not want to run extension cords across your garage floor, there are other options available:

  • A portable heater will provide enough heat for an average-sized garage. Make sure that it is placed at least 6 feet away from flammable materials such as paint cans and wood pallets so that no sparks fly around in the air. If you decide against using a propane heater (which produces fumes), then consider using natural gas instead because it is much safer than butane fuel tanks found on most portable heaters (but don’t forget about safety precautions).
  • You could also try using a propane heater if possible; however, due to its large size it may be cumbersome if working within tight spaces like underneath cars’ hoods or inside closets where temperatures fluctuate rapidly throughout each day due to their proximity to heating ducts located above them.”

How long does it take for garage floor epoxy to cure?

The length of time that it takes for the epoxy coating to cure depends on several factors.

Will epoxy crack in cold weather?

Garage floor epoxy is a two-part coating that is mixed together to form a durable coating on concrete floors. Yes, you can use epoxy in the winter, but there are some things you should know first before applying the coating.

Epoxy floor coatings should be applied when the temperature of the concrete is 50-90 degrees F., as this will help ensure proper curing and bonding.

If your garage floor is particularly cold, it may take longer for your epoxy to cure properly. It’s best to wait until spring or summer before applying epoxy so it has more time to cure at its ideal temperature range: 70 degrees F with relative humidity between 45% and 65%.

Are epoxy floors cold in winter?

Epoxy floors are cold, and keeping them warm is a challenge. If you’re placing your epoxy floor in a basement or a garage that isn’t heated, then you may want to consider adding heat beneath the flooring.

Adding radiant heat beneath your epoxy garage flooring will keep it warm even when it’s below freezing outside. The average cost of installing radiant heat under an area like this ranges from $1,000-to $2,000 depending on how big your garage is and what kind of heating system you choose for installation.

Another option for keeping an epoxy garage floor warm is insulation underneath it—using spray foam insulation like Great Stuff Pro™ Open Cell Foam Insulation between the joists will help keep out drafts and provide an extra layer of warmth for colder days.

What temperature is too cold for epoxy?

Epoxy is a thermoset plastic, which means it’s essentially like glue. This means that it will cure, or harden, at room temperature. But if the epoxy is below 40°F, the curing process will take longer because epoxy has to warm up to get past its glass transition point (the temperature at which it becomes a liquid).

How cold is too cold for resin?

You may be wondering, “How cold is too cold for resin?” The answer is that you can use epoxy in temperatures as low as 50 degrees, but if the temperature drops below this threshold and stays there, your epoxy will not cure properly.

When it comes to how cold it is outside, the lower limit for using epoxy is generally considered to be 50°F (10°C). When using an air conditioner or space heater to keep your garage warm during the winter months, simply make sure that the temperature stays above 70°F (21°C) for best results with any kind of resin.

If necessary, add heaters or fans—or both—to help circulate heat throughout large areas like garages so that no one part gets too hot while others remain cooler.

Does epoxy dry better in heat or cold?

Epoxy does not dry better in heat or cold. It simply dries faster at higher temperatures and slower at lower temperatures. In fact, it is recommended that epoxy be applied to a surface when the air temperature is between 55 degrees F (13 degrees C) and 100 degrees F (37 degrees C).

The hotter the day, the more important it is to apply your epoxy in a temperature-controlled environment because it will dry faster than if you were working outside on a hot day.

The more humid the environment is, the longer it will take for your epoxy to fully cure so using an electric fan can really help speed up this process!


Can you apply epoxy in winter? The short answer is yes, but it’s not as simple as just slapping on some epoxy and waiting for it to cure.

Generally speaking, the colder it gets outside, the slower your epoxy will cure. However, there are ways you can work around this challenge:

  • Use a space heater or heat lamp for extra warmth. If your garage isn’t insulated enough and has low ceilings that trap cold air at floor level (like many garages do), you may want to consider using this method in order to increase your working temperature and help your epoxy cure faster.
  • Invest in a good respirator mask with carbon filters and a face shield so that you don’t breathe any harmful fumes while working with urethane foam sealants or adhesives like 3M 5200 or Sikaflex 221A—especially if there’s an open flame nearby!
