How To Stain a New KDAT Deck

DeckStainHelp.com has become the Internet’s go-to site for all things wood deck restoration-related. As before, we recommend you wait 1-2 months to stain new 2024 KDAT wood surfaces to allow the wood to weather, creating an ideal porous surface that will hold the stain better. We encourage customer interaction on our site, so if you have stained a new KDAT surface, we want to hear from you. Feel free to leave us a comment with pictures of your projects if you have them.


When to Stain a New KDAT (Kiln Dried Wood)

Deck? Right away or wait?

Although pressure-treated lumber is protected against fungi and insects, regular maintenance is required to achieve optimal weather protection. Staining and occasionally refinishing the wood will ensure your wood project will be enjoyed for years to come.

However, when pressure-treated, or other types of wood are new there is a waiting period of 3-6 months when using most stain brands. The wood has to season before you can stain or seal it. New wood has a high moisture content. As the wood dries out it shrinks and becomes more porous. Some weather damage can occur during this seasoning period but staining new wood too soon can lead to staining performance issues as trapped moisture will wreak havoc.

A way around this issue is to use KDAT (Kiln-Dried After Treatment) lumber. Moisture is removed from the lumber prior to arriving at the lumberyard. The advantage of KDAT lumber is that you can stain or seal it much sooner. Because all the moisture has been previously removed, the wood will not shrink or need as much time to season. Basically, it is like seasoned wood that has not had to season naturally and has been susceptible to the elements. You will need to prep the surface though with a deck cleaner and wood brightener before staining. This will help remove any mill glaze. We also suggest only applying 1 coat of stain to the new KDAT wood.

Best Tips and Steps for Staining New KDAT Decking

  1. Install wood first. Wait for 1-2 months of weathering.
  2. Prep wood with a deck cleaner and wood brightener to remove mill glaze and or open grain for the stain.
  3. Choose a stain such as Armstrong Clark. This allows maximum penetration into the wood grain.
  4. Apply only 1 coat of the stain.
  5. Apply a light maintenance coat 9-18 months down the road.

Stain new KDAT decking within 1-2 months after installation for the best results. No need to let the wood weather longer. Staining a new KDAT deck properly will allow you to enjoy your new deck for many years.

Hi, I have a customer we’re building a deck for this week. We were planning to use KDAT decking but they just told us they won’t be staining it until next year. Will it weather too much between then and now?

I live in N.W. Georgia and built a new KDAT deck. Project was completed August 1, planning to stain deck at end of November, but I’m concerned about it being too cold. Should I wait until spring? (9 months after deck completion) or just proceed as planned. Thank you.

The Yellawood KDAT website and rep say to stain prior to or immediately after installation. But you seem to be saying wait 1-2 months for weathering. I live in Florida and we have regular rain storms and I am concerned about the wood losing the benefiyt of already having been dried. What is you best advice? Please send response also to meplunkett454@gmail.com

I just recently re-stained my deck and in the process discovered that I needed to rebuild the railing. I will be installing a new rail with KDAT and cable railing this weekend and will let the new wood weather one to two months as advised. Once the railing is ready to be stained how would you recommend prepping the railing for stain (cleaner, brightener, etc.) while not damaging the stain on the deck floor. I just re-stain the deck for a few weeks ago and would prefer not to strip it down and redo the whole thing.

Building a deck. Understand the logic of waiting 1 to 2 months for wood to weather and become more pourous. How do you eliminate the scratches and dings that will occure during that time period, prior to staining, since sanding isn’t an option.?(You’d have to wait for the wood to weather again). Won’t the scratches be more prominent when the stain is applied? I’m not doubting you guys at all. Just wondering if there is a solution to this problem. Maybe the answer is that it’s a deck, and not an interior floor. Appriciate your feedback.

We have a KDAT deck that was installed several months ago. It is inside a screened porch and has been covered with cardboard. The bottom surface of the deck is exposed to the air but not water or sun. Am I safe applying Defy Extreme or do I need to expose the boards that have been covered with cardboard for some time, and if so, how much time? Thanks
