Understanding the Ideal Temperature for Staining Wood

Temperature is one of the most crucial considerations if you want to successfully stain wood. The ideal temperature of the wood when you stain is between 50 and 90 degrees Fahrenheit. This is the threshold where the stain bonds, cures, and dries properly and gives you a high-quality finish.
Many experts would even argue that somewhere between 60-80 degrees is even better if you want the ideal results.
But what do you do if you aren’t in an ideal situation? It may be difficult, but there are still ways you can make it work. Several tips can help you get the best possible results, even if you can’t get your wood within the ideal temperature range.

How Temperature Affects Wood Staining

Anything below 50 degrees Fahrenheit would be considered “too cold” of a temperature for staining wood. On the other hand, above 90 degrees is too warm and poses its own unique set of problems during the staining process. Here’s how the two temperature ranges impact how the wood takes your stain.

Wood Staining in Cold Temperatures

If your wood is too cold, it takes longer to cure. Certain types of stains, like oil-based ones, can take up to twice as long to fully cure. The good news is that you can technically still use the oil-based stain — you’ll have to account for the extra time. 

It’s important to note that this can still vary based on the product you use, humidity levels, and other environmental factors.

Sealing can be a much more frustrating problem. Wood that’s too cold won’t allow the stain to properly soak in, leading to an uneven final product. 

There’s a higher risk of this happening with water-based stains since they have a harder time bonding in low temperatures. That’s because the water in the stain can freeze or evaporate before the wood has the chance to absorb it. 

There’s also the chance of delamination in colder temps. This is where the stain layer starts peeling or cracking off the wood. Delamination can create extra work for you, requiring additional coatings that can still potentially look uneven.

Wood Staining in Hot Temperatures

If you’re dealing with a warmer temperature for staining wood, you’ll likely have a host of different issues. For example, warmth can make a stain dry too quickly. This might prevent the stain from fully soaking into the wood and leave you with an uneven finish that doesn’t last, meaning it’ll eventually require extra coats.

Sealing and adhesion can also be a problem in higher temperatures since the rapid drying could cause the sealant to not adhere properly. The added heat can also change the appearance of your stain and affect the final look. The warmer your wood is, the more likely the stain will look darker or more saturated than you expect.

Tips for Staining in Cold Temperatures

If you do need to stain some wood when it’s at a cooler temperature, here are some helpful tips that can improve your results.

Use Oil-Based Stains

While it’s true that oil-based stains will mean you’re waiting longer for it to cure, it’s still more forgiving than the water-based counterpart. The high oil content makes them more freeze-resistant, so they’re generally a better option if you’re staining wood with a colder temp.

Use Thinner Coats

If you use thinner coats of stain, you’re less likely to have issues with drying and adhesion. It’s more likely to absorb correctly and helps the stain cure into an even finish. Thinner coats are also beneficial because they allow you to be more flexible with how you apply the stain.

Choose the Right Time to Stain

Unless you’re under time constraints, you might consider just picking a different time to do your staining when you can get the wood within the right temperature range. Check the weather forecast and see if you can make time to stain your wood on a day when it’s easier to get within the 50-90 degrees range.

Take Your Time and Wait for the Ideal Temperature for Staining Wood

Whether you’re dealing with warmer or colder temps, your best bet is to wait for circumstances where you can ensure the ideal temperature range. But if you can’t, it’s worth knowing exactly how the temperatures will challenge your staining project. 

This gives you the opportunity to make adjustments so you can still get a good outcome and bring out the natural beauty of your wood.
