Did you forget about those couple of cans of paint that were left in the garage overnight while it was freezing outside? If you haven’t opened the can yet, you may be wondering, “Can my paint actually freeze in cold weather?”
Solvent-based or oil-based paints will freeze if left in extremely cold temperatures. Solvent-based paints have a higher freezing point than oil paints, but they both have a similar process to thaw out.
Want to know everything you can about frozen paints to see if you can still use yours? Keep reading below to understand how to use paints after they’ve been frozen and what you can do to help the process.
Will paint dry below freezing?
Paint will dry if temperatures are below freezing, but it will take a very long time. The colder the paint is, the longer it will take to dry. You can use a blow dryer in extreme cold to try and dry your paint faster.
For example, a gallon of paint will take around 15 hours to dry at 20°F. (To make it easier for you, remember that every 10° colder is roughly twice as slow.)
Temperature also affects how watertight the coating will be and how well exterior paints hold up to abrasion from brushing or scrubbing.
A gallon of paint should never be allowed to freeze on a wall or other surface – even if it’s out in the cold overnight.
It may become very hard to remove all traces of it once it thaws, resulting in stains that can’t be removed with water alone. This means scraping away at dried paint with a putty knife or sandpaper.
If you experience condensation, remove it as quickly as possible by opening windows and doors to let the warmer air inside your home out.
You can also use electric space heaters for temporary relief during this time of year. Be sure that these are turned off before they begin to generate frost on the windows.
If the paint does freeze, you should remove any excess moisture from your home to prevent future freezing.
You can do this by running a dehumidifier or opening all doors and windows for an hour or two to let the moist air out of your house so it doesn’t come into contact with cold surfaces.
Can Paint Be Used After it Freezes?
Paint can be used after it freezes in the can if it does not contain any clumps or foul odor after it thaws. You will need to keep the paint at room temperature for at least 24 hours before using it.
When your paint freezes in the can, it needs time to warm up and become liquid before using it again.
For a gallon of paint to become liquid, you should wait at least 24 hours outside in warmer temperatures (above freezing) or leave your can out inside overnight if temperatures are below 32°F.
If allowed to freeze and then used on surfaces, the paint will be thick and have a rough texture.
Paint can also freeze in the brush or roller, rendering them unusable. If this happens, you should use hot water to remove paint from these items as soon as possible – do not wait until it thaws on its own!
If your paint is frozen during the application, stop spreading it, so the paint doesn’t start to thaw and drip.
If your exterior paints freeze, you may need to apply a new coat of paint as they will not be watertight on their own anymore.
What Temperature Does Paint Freeze?
Paint can freeze in temperatures below 32°F, and if it does, the safest way to thaw the paint is to leave it out in warmer temperatures for 24 hours or more. However, paint should never be allowed to freeze on a wall or other surface.
In this situation, it’s also paramount not to use plastic containers such as a 5-gallon bucket or container to store paint since these can also cause the paint to freeze and become unusable.
Any paint left in the garage or car while temps are below freezing is susceptible to becoming frozen.
If you know temps will dip below freezing and you plan on using the paint in the near future, it’s best to store it inside the home. Otherwise, you will have to wait for your paint to thaw to begin using thoroughly.
Colder paint will take longer to dry, so even if your paint has thawed but it is still fairly cold, you may want to wait a while before using it.
You will want to stir your paint very thoroughly before starting a project after it has been frozen. You don’t want your paint to have any solid pieces before applying them to your walls.
Can Paint Be Stored in Cold Weather?
Paint can be stored outside in cold weather but should never be allowed to freeze. The colder the paint is, the longer it will ultimately take to dry when applied.
If you are storing paint in cold weather, keep it protected from the cold by placing blankets on top of the paint or putting it in between items to stay warm.
Paint can also be stored inside your home but should not be kept on a cold surface such as an unheated garage floor where it will freeze more quickly. Be sure that you store any cans of paint upright so they will not freeze.
If you plan on storing paint overnight, be sure it is out of the cold and in a heated area or garage that doesn’t drop below freezing temps.
Never pour any frozen paint back into its container, as this will cause the entire paint to become unusable when stored outside during winter months if temperatures are more than 32°F.
If the paint is exposed to cold weather, you may want to put a heater on the paint for 30 minutes to see if you can get the paint back to room temperatures.
What Happens if Paint Gets Too Cold?
If paint gets too cold, the elements inside the paint start to bond together, and this will cause clumping inside the paint. If left in the cold for too long, you will need to mix it before using it again thoroughly.
The chemicals in paint are meant to stay in a liquid state. In warm temperatures, the paint will stay in its natural liquid form for long periods of time.
If left in cold temperatures, the liquid state starts to transform into a solid over time. At first, you will only have small clumps and hard spots in the paint when you open the can. Mixing the can thoroughly help to alleviate these clumps.
If the paint inside the can starts to freeze, you will need to wait longer to use the paint.
After mixing all your clumps out of the can, your paint will still be fairly cold. This will make it harder for the paint to dry after you have used it. It will take several hours longer to dry than regular temperature paint.
Is Acrylic Paint Ruined if It Freezes?
Acrylic paint won’t be ruined if it freezes. The acrylic will eventually re-absorb the water and thaw out on its own. Once the paint has unfrozen, you’ll need to mix very well to break up any chunks or clumps that may be in the paint.
Like regular paint, acrylic has a freezing point and will start to solidify if left in freezing temps for too long. This doesn’t ruin the paint because the solid pieces will eventually thaw out over time in warmer temps.
The problem is when the paint is left to freeze several different times throughout one season. The constant freezing and thawing can cause the paint to become unusable.
Like regular paint, if the acrylic paint is too cold, it will have a harder time drying on your walls or items. The drying time will be significantly longer for colder paint and could take several days to complete.
Store your acrylic paint inside the home in a warmer place to prevent your paint from altering its physical composition.
How Long Does It Take for Paint to Freeze?
It can take anywhere from 1-2 hours for the paint to freeze in temperatures at or below 32 degrees Fahrenheit. The paint will start to clump together at first and continue to solidify the longer it’s left in the cold.
If your paint is already cold when put in freezing temperatures, the process could only take 45 minutes. If the paint is very warm, or even hot, it could take the full two hours when put in freezing temps.
You will want to remove your paint from freezing temperatures if given the opportunity. Freezing is bad for the paint and drying process.
Latex paint is water-solvent, so that it will freeze at around the same temperatures as water. On the other hand, oil-based paint is less resistant to freezing and will not take as long.
If you notice the weather changing or you’ve checked on the weekly predictions, you may want to move your paint out of freezing areas. This can help sustain the lifespan of your paint from going through harsh environmental conditions.
At What Temperature Does Oil Paint Freeze?
Oil paint will freeze at -4 degrees Fahrenheit because it consists primarily of linseed oil. Because most freezers are set to 0 degrees Fahrenheit, you could store your oil paint in the freezer with no issues.
Applying oil paint when it is at these low temperatures can be harmful. The cold paint could cause a canvas to become brittle if you plan to create an art piece.
If you are using oil paints for a project but want to take a break, you can store the paint in the freezer to avoid oxidation and evaporation. This can be especially helpful on a hot day to avoid wasting a lot of paint because it becomes too dry.
You may prefer oil paints if you live in already cold climates because of the lower freezing temperatures. This will help you complete your home or creative projects without having to worry about your water-based paint freezing on you.
Is Primer Still Good If Frozen?
All primer will still be good if frozen, but it will need to be kept at room temperatures for up to 48 hours. This allows the primer to thaw and get rid of any clumps that formed in the primer.
Like paint, primer can be solvent-based or oil-based. The solvent-based primer has a higher likelihood of freezing since the water-based material will freeze at the same temperature as the water.
On the other hand, oil-based primer is more resistant to freezing temperatures and will take longer to freeze in cold conditions.
Either way, both of these can still be used after freezing. The frozen paint will need to thaw in room temp for a couple of days. This should be enough to get rid of any clumps, but you will still want to mix the primer thoroughly before applying.
What Happens if Chalk Paints Freeze?
Chalk paint, like other paints, will solidify if it reaches temperatures below freezing. You can still thaw the paint at room temperature in order to use it at a later time.
Just like with any other solvent or oil-based paint, if your chalk paint reaches a certain temperature, it will begin to freeze.
You do have about two hours to move the paint out of freezing conditions before it solidifies fully. If the paint does reach solidification, you will need to transfer the paint inside your home for at least 24 hours.
To give it the best opportunity, you will want to
Will Paint Cans Explode in Cold Weather?
Paint cans will not explode if exposed to extreme cold weather. The paint will freeze in very low temperatures, but this will cause the paint to condense instead of expanding.
Only if you leave your paint cans in extreme heat will they have the possibility to explode. This is because as the paint is left in the can, the heat is producing more and more pressure inside. Once this pressure becomes too much, the pop will explode off, and paint will follow suit.
In cold weather, it can have the potential to crack and become brittle because the frozen paint is wearing down the durability of the materials.
This process does not produce any pressure inside the can, so it won’t cause the paint to explode.
Using Frozen Paint
The paint will freeze if left in freezing weather, and the paint will solidify. You can still use paint that has been frozen, but you will need to leave it at room temperature for a couple of days.
All paints have the ability to freeze, and you want to make sure they don’t freeze over more than once, or they could be unusable.
