Cold temperatures can affect varnish performance, but cool varnish gives a longer brushing window. To clean up the brushes between sessions, I would rinse them several times in diesel, blow them dry with the compressor and saturate them with WD-40.

How cold is too cold to varnish?
Ideal Conditions are 70 degrees F and 50% humidity. Refinishing furniture in a space that is below or above the 65-75 degrees F range can lead to problems, and a space below 55 degrees F is definitely too cold.
At what temperature can you apply varnish?
You can varnish anywhere between 50 and 80 degrees, but ideal conditions are 55 to 65 degrees with 45 to 55 percent relative humidity. Don’t varnish in the wind because dust is the enemy of a smooth, flawless finish so you have to minimize its impact whenever possible.
How long does it take varnish to dry outside?
METHOD OF APPLICATION The following are average CURE times based on recommended temperature and humidity: 21 days for water-based products. 30 days for oil-based products. You can use a piece lightly after about 7 days but be cautious – the finish will still be curing for another 2 or 3 weeks.
Will polyurethane dry in the cold?
In colder temperatures, polyurethane tends to dry more slowly, which can cause a whitish film to develop.
What happens if varnish in cold weather?
Cold temperatures can affect varnish performance, but cool varnish gives a longer brushing window. To clean up the brushes between sessions, I would rinse them several times in diesel, blow them dry with the compressor and saturate them with WD-40. Varnish does not flow from a brush evenly.
How warm does it need to be to apply polyurethane?
In general, polyurethane can be used in the temperature range of -62°C to 93°C (-80°F to 200°F).
What happens if you stain wood in the cold?
Effects of Cold Temperatures If the room air is too cold, it slows the staining process. Water-based stains rely on evaporation to dry and cure properly. In a cold room, that evaporation process is much slower.
Can you sand wood in cold weather?
ANSWER: Refinishing furniture in a space that is below or above the 65*-75* F range can lead to problems, and a space below 55* F is definitely too cold. One issue caused by cold temperatures is the development of dimples in the finish called “Orange Peel”.
Can you stain wood in a cold garage?
I use an oil stain in cold weather all the time. As long as you let it dry overnight you shouldn’t have a problem. You could also use a alcohol based dye stain without any problems at all. It’s the finish you need to watch the temperature.
Can I apply varnish outside?
Best Uses. The high solid content and water resistance of varnish make it particularly apt for use on water-exposed outdoor decks, deck chairs, and boats. Its low toxicity, however, means that it’s equally safe to use near the entryway on exterior doors and trim.
Does varnish dry quicker in the sun?
It dries as the solvent (which may or may not be water) evaporates. It isn’t like masonry where time and moisture are critical. There’s no problem applying urethane in the sun other than the challenges it poses to the actual application. Very quick dry times mean less time to get good coverage and work out runs.
Can you dry varnish with a hair dryer?
Yes if you blow air (especially heated air) over various oil-based finishes they will dry faster.
What temperature can you varnish outside?
First and foremost, you need to ensure that the ambient temperature isn’t too hot or too cold at the time. Ideally, you should be looking at keeping the temperature between 70° F and 75° F, in order to cure the varnish most effectively. When temperatures are too low, curing times can be extended by days or even weeks.
How do you finish wood in cold weather?
Finishing in Cold Weather
- Try to figure out a way to bring the temperature up to at least 55 degrees.
- Apply very thin coats for faster drying times.
- As always, keep the air moving in the room to promote drying.
- Try to keep the projects as far from the floor as possible.
What temperature does it need to be for polyurethane to dry?
Note: Above dry times are based on good ventilation, temperature of 77°F and 50% relative humidity. Lower temperature, higher humidity, lack of air movement or application of thick coats will extend drying times. Slight ambering may be experienced when Polyurethane is applied over light-colored wood surfaces.
