Why Do I Need to Wait to Stain My New Deck with TWP

info buttonAfter a new wood deck has been constructed it is important to protect it from the elements. Unprotected wood will be prone to graying, warping, cracking, splitting, and mold/mildew infiltration. Protecting your wood deck is easy with TWP Total Wood Preservative. There is however a waiting period to allow new wood to season prior to stain application.

New wood is commonly called “green” wood. Meaning it has not had time to season or dry. It has a very high moisture content. You may notice the difference in weight of a newer deck board and an older one. The newer one is much heavier due to all the moisture it is holding. As the wood dries it also shrinks. This is noticeable in the gaps between deck boards. They will be tight together after first construction and as the wood shrinks the gaps will become larger.

 

Applying TWP deck stain to a newer deck too soon can result in a failed deck coating. The stain will trap moisture in the wood, which can cause several problems. Mold and mildew can spread quickly underneath the stain eventually leading to rot and decay. The moisture will also keep the wood stain from penetrating properly and may cause it to peel and flake off the surface. TWP wood stain is designed to penetrate deep into the wood for maximum protection. If the wood has too high of moisture content the stain cannot penetrate correctly.

There are some people who believe you have to wait and entire season or 1 year before you can stain new wood. This is normally not true and actually a lot of the wood damage can occur in the first year if the wood is not protected. Most types of wood will be ready to stain within 4-12 months after being erected. All new wood should be prepped with the Gemini Restore Kit before staining. Wait time can vary depending on sun exposure, weather, and temperatures.

For TWP wood deck stain to give you the best results on a new deck, the moisture content of the wood should be 15% or less. This can be easily checked with a moisture meter. If you do not have access to a moisture meter and you have waited several months of hot summer weather, you can do a drop test with water. Sprinkle a few drops of water in several areas of the deck. If the water soaks in right away indicating the wood is dry it is probably okay to stain. If the water does not soak in right away, the wood may still be holding too much moisture.

Be sure your new wood deck has had plenty of dry time before applying TWP deck stain. This will guarantee proper wood penetration giving a naturally enhanced look that will last and perform as expected.

    Hi- what about waiting period for new cedar railings and posts only - aren't these somewhat rough? Old decks will be striped cleaned and refinished - don't desire to have non-finished railings/posts.
    No those are not rough but smooth.

    We live on Lake Sinclair, in Eatonton, GA - 90 miles east of Atlanta. We installed a new dock with pressure treated wood in January of this year 2015, when can we put a clear stain/sealer on our dock? The person who built the dock said we should wait only 1-2 months but I'm thinking longer?

    St. Louis MO, sun in morning and shade in late afternoon, new deck red cedar wood built just over 3 months ago. Is Oct 18th too early to stain, and what stain would you recommend?

    Please read this: http://www.twpstainhelp.com/prepping-new-wood-for-twp-stains/

    You would want the 100 Series and only one coat after the proper wait and prep.

    Is TWP stain a good choice for T-111 rustic siding on my pole building? If so, should I wait to apply or can I pre-stain the panels before I install them on the building?

    thanks, Mark

    Best to install, weather for a few months, prep with Gemini Restore Kit, then stain for this.

    I just installed a new 900sf cedar deck in upstate NY, the deck is 12’ above the ground so I will get plenty of air flow and winter is coming fast. You recommend waiting 4 to 6 months before applying the stain. My question is why wait so long? If I were to install a wood floor in my house I could seal it right away. Why can’t I do that with an exterior wood floor? I am going to use the 1500 cedar stain. If I wait much longer I won’t be able to seal it until April or May depending on the winter and I'm sure it will be gray by then.

    If you stain new wood right away with TWP it will not absorb and will prematurely fail. Turning gray and prepping is okay and normal.

    Hello! I'm interested in putting a clear cote on my new redwood fence. The boards are redwood and the post and kicker are pressure treated.The fence is now 3 weeks old. How long do we wait to apply the TWP Clear coat for the first time. Do we need to do any prep work like pressure wash?

    I have a 1 year old, pressure-treated, pine fence that I would like to stain for the first time. It does not appear to have any greying anywhere- should I still clean and brighten the wood with a restore kit or can I just clean it with soapy water prior to staining? Should I go with the high estimate for coverage since it is the first time staining and it is a fence not a patio? Do I need to apply a second coat or does it just depend on how much the fence soaks up?

    You need the Gemini Restore Kit for the prep. Fences are usually rough sawn wood which means they are more absorbent and coverage can be less. Probably will need the two coats.
