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.

    Does one need to use the cleaner/brightener on verticals? I will be staining a new (6 months old) pressure treated deck with your TWP 1500.

    Yes you do need to prep the verticals and the horizontals.

    I had a new cedar deck built and completed on September 10, this year. The customer wants a clear stain to maintain its current look. How long should I wait before I stain it? Can I wait till spring and maintain its original look? I live in central Minnesota. Thanks!

    Neil,

    As the article stats, you should wait until Spring and prep with Gemini Restore Kit. Make sure that your customer knows that the Clear will not protect from UV graying. You must have a tint/color in the stain.

    We built a new porch in February 2015 using treated yellow pine wood. We live in Northern Virginia. We are thinking of staining in October 2015. We like the look of yellow pain. What stain would you recommend for the porch and how many coats?

    One coat on new wood. You need to use the 1500 Series for your area. Prep first with the Gemini Restore Kit.

    I just finished prepping a 2000 sq ft, two year old cedar deck. Had to strip off a bad stain, sand, and brighten. Do I have to wait a full 48 hours to start staining after brightening if the wood is already reading less than 15% moisture content after 24 hours in sunny 90 degree day?

    Yes you should wait 48 hours.

    We have a new deck that we just stained with TWP. Because of traffic and investment and as we are pleased with the stain results, I would like to apply a clear coat over the stain coat.
    How long should I wait to apply the clear?
    Any reservations or notes?
    Thank you.

    You cannot apply a clear coat sealer over the TWP. Did you read this as well about new wood?:

    [b]how long do I wait before applying clear coat to a new, rough cut, redwood fence?[/b]

    New rough cut wood can be stained right away as long as the wood is dry. Just one coat on new wood.

    I have a 7 month fence I am treating with your 101 do I have to wash it with bleach? Will I have to pressure wash or use a water hose?

    As the article states you should prep it with the Gemini Kit, not bleach while lightly pressure washing.

    I am interested in a darker stain like walnut. I do not like the color sample shown on your web site - Dark oak 103. I am wondering if the actual color of Dark Oak 103 might look different when applied to yellow pine and how true to color is your web site color.

    Colors vary drastically based on the wood type, wood age, prep of the wood, application, etc. Best to get a sample from our site to test.

    We just had a new redwood deck completed. We're in Norhern California and the deck is on a sunny south side. We've heard different waiting periods before sealing- from two weeks to one year. Please advise. Also what stain color would look most natural other than clear since we've heard that clear does not offer enough sun protection. Thank you.

    As the article states, 4-12 months and you will need to prep first. Lightest tint is the 1515 Honeytone.

    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.
