Best Deck Staining Temperatures

We here at Deckstainhelp.com appreciate your loyalty. For 2024 and beyond, we are committed to being your go-to source for deck staining tips. Like last year, we recommend you stain your deck when the temperature is between 45-90 degrees and you are sure it will be a few days with no rain.


The Correct Temperatures for Staining Decks

It is important to know the tolerances a new deck stain will allow without hindering its performance. One of the most crucial areas of concern is air temperature. Temperatures need to be in the safe zone while the deck stain is being applied and for 8-12 hours after.

Low Temperatures

According to most deck stain manufacturers, the air temperature should be no lower than 45 degrees while being applied. This is only an average. Some deck stains need to be applied when the temperature is at least 60 degrees. Check the label on the deck stain you are using.

In addition, once the stain is applied the temperature should not drop below freezing for 8-12 hours. This can otherwise hinder the curing process of the stain. Penetrating stains will not cure properly while film-forming deck stain’s adhesion will be jeopardized. This can lead to a lack of stain performance and cause premature failure of the product. If temperatures are forecasted to drop do not stain the deck, if you have already started do not proceed.

High Temperatures

Just as important as low-temperature tolerances are high temperatures. This is especially important while the deck stain is being applied. Do not apply stain in extremely hot temperatures. When it is 90 degrees and above care should be taken if deck staining is necessary.

Try staining in the morning before it gets hot or during a part of the day that your deck is shaded. Never apply deck stain in direct sunlight on a hot day. Staining a deck in the sun and/or on an extremely hot day can cause the stain to flash dry on the surface. This prevents the stain from penetrating properly and will hinder its longevity. Flash drying also causes the stain to appear uneven and blotchy giving you poor results.

Deck staining projects can be costly and labor-intensive. The last thing you want is lackluster results because of the weather. Follow these guidelines for correct temperatures for staining decks so your final results will not be jeopardized.

Hello,
I live in the tropical southern Caribbean. Built a pine deck with weathered wood in February. Because of supply issues re the pandemic, the only stain available was sherwin williams semi transparent oil based stain. It went on well and water beaded off the surface when it rained. 2 months later the color totally changed. The stain is dark, the wood dark and grayish and the stain was stripping off. Water was soaking into the wood. Last week, the contractor sanded the whole deck with a belt sander and the wood was still dark. He re-stained with the remaining SW stain until I can import something better. Our rainy season has just started. It lasts till November/December. What do you recommend? The photos show when first stained, the deterioration, and after re-staining.

Thank you. What do you suggest is the best stripper and brightener? I can ship anything in. Though the wood was not “new wood”. It weathered for 3 weeks when I was looking for stain. Water was soaking straight through. It started cracking and splitting both horizontally and vertical. So much so that we had to replace about 6 boards. They split and peeled back like if you’re opening a sandwich. The contractor recommended that I stain it right away. Only 2 of the replacement boards are new PTP and even those are soaking water easily.

I’m staining a redwood deck with semi transparent oil stain. Didn’t consider temperature at night when I prepped everything. Lows are in the 20’s but highs are in 60’s. Could I stain in morning after it warms up and then stop around noon to allow for dry time? Large deck all prepped and been tryin to do job for two years!!

I plan to stain during the morning when it’s cooler (15-18cekcius). The sun gets around to my dr k around noon and the temperature will be 25 cekcius. Is this too hot?

Is there a deck stain/waterproofer that doesn’t cause the boards to retain heat? The natural wood is easy on bare feet but I’m worried that waterproofing might hold in the heat making the pool deck too hot for bare feet.

Hello,

I used RAD cleaner/stripper, and brightener to prep a project for stain. Weve had a day of rain mixed into the 48 drying time, and I’m wondering if I have to repeat any of the steps before applying the stain? Its been apx 4 days since prepping.

Thank you.

Forgot to say, it is a cedar deck that I just sanded and cleaned and brightened yesterday. Seems dry this morning and a few drops of water sink through the wood in a few seconds.

If I strip a deck in 70 degree weather, then it drops to 47 overnight, Is that okay? Then could I stain the next day and then the following night it’s supposed to be 40 degrees.

Thanks!

I’m thinking about staining my new deck this evening after the deck is shaded by the house. I can’t stain in the morning as most blogs suggest because the deck receives sun from morning until about 6 pm before it begans to receive shade from the house.
The temps at 7 pm tonight are supposed to be 84 degrees with 70% humidity. Tomorrow will get over 90 degrees and we are scheduled for a small amount of rain the following day.
Will this be a good day to stain?

Somehow I managed to answer on Helen’s post. I meant never stained new wood. I built the deck last summer. I used TWP’s cleaner and brightner but still have a lot of gray and wood fuzzies. I’m considering sanding the platform to get rid of both before I stain with TWP100

We have a treated lumber deck that has weathered gray for about 3 years. We live In he tropics, Puerto Rico, where woods decks are not that common. the dreck is gray and has some very dark areas where the AC have leaked on it . I really do not mind the gray but want to protect the deck from further damage. I want to avoid high maintance stain removal in a couple of years. Our deck faces west and gets the hot afternoon sun all year round. To further complicate the selection Process we are in Puerto Rico and some brands are just not available and probably can not be sent. We have Home Depot, Ace Hardware, Benjamin Moore and Sherwin Williams, what do you dexperts recommend that I may actually be able to find?

It might take me a few weeks to answer as it is even more complicated, I live on a small island, Vieques, off the coast of Puerto Rico and I will have to go to those places and make a list.Home depot has a selection of Behr products, ready seal and Flood. Benjamin Moore has stores here and offers what ever they make. The biggest lumber yard in PR is affiliated with Ace Hardware and has a huge inventory, I will check them out next visit.

I’m sorry, I meant new wood as never stained. The wood has weathered since last summer. I’ve been told not to sand the deck before I stain it. Is there a reason? I’m using TWP100

This was incredibly helpful. I have a new 6ft cedar fence installed about 7 weeks ago and am ready to stain. However, the temperatures here are upper 90s during the day and upper 70s at night, with very high humidity (70%+ in Eastern Kansas). My fence is shaded at certain times of day, while some is always shade (Lots of trees). A large section is always in the sun. How should I go about staining? Mornings only or wait until it’s cool again?

Hello, we have prepped our deck (stripped, brightened, power washed) and plan on staining it tomorrow after 48 hours of drying. However, it is projected to be a high of about 95 degrees by about 1 pm. If we stain early in the morning before it hits 90 will the stain be okay? Also, projected to rain about 24-30 hours after staining. Could we cover the newly stained deck with tarps to prevent damage?

We are scheduled for 4 90 degree days in a row.
The morning is 72 degrees , I can completed the stain around 2 hours before the temp gets above 88 degrees. Took me 10 hard hours to prep. If I decide to wait can I cover the deck with plastic tarps for three days so my deck stays ready for staying when the weather breaks ?

Thanks for the info you provide. High temp today is 55 with 15mph winds. Low tonight 38. No rain forecast for the next 48 hrs. Can I stain my deck today? I’m using Restore a Deck. They recommend above 45 degrees for staining. Not sure about the wind factor though.
Thanks.

If I am worried about a heavy due in the evening after staining with oil based stain in the morning, would covering the deck with plastic tarps pose a problem.

Did not know this info before staining. Now we have some of those unwanted results of staining in direct sunlight…overlap marks, uneven penetration, “flash drying”, etc. Should we sand and re-do the stain in those areas?

Good info. I just washed my cedar deck for restraining. I plan to stain tomorrow. Temps will be in high 90-107 range this week. Too hot? Should I wait to stain when temps cooler? Thanks!
