TWP Stain Tips for New wood Decks in 2021

When applying TWP Wood Stains for the first time to new wood there will need to be proper steps taken. New smooth wood or decking is not ready to be pre-stained prior to installation or stained right after installation. It is best to follow the directions of the TWP Wood Stain when it comes to applying a coating to new wood for the first time, not the lumber yard or the paint store’s as they do not understand the proper prep needed.

TWP and New Smooth Decking or Exterior Wood

It is important to understand that new smooth wood is not absorbent enough for the TWP Stains. New wood contains a higher moisture content and a “mill glaze”. Mill Glaze is a waxy film that results from the fast turning blades that cut the profile on a manufactured log. The high speed of the turning blades produces heat that draws sap and moisture out of the log. As it cools and dries, it creates a film or coating on the logs. This will hinder the TWP’s ability to penetrate into the wood grain.

Note: New Rough Sawn vertical wood/fencing can be stained right away with no wait and with no prep as it does have mill glaze and is very absorbent. Just make sure the wood is fully dry. If Rough sawn wood has aged or oxidized (grayed) then it will need to be prepped with Gemini Restore Kit. One coat for most instances of newly installed Rough Sawn wood.

Let the Wood Weather First

TWP wants the wood to weather and dry out for 4-12 months after installation. This will allow the moisture content to drop and the exposed wood cells will oxidize from the sun’s UV, turning slightly gray.

Prepping New Wood for TWP Stains

After letting the wood weather it is time to prep the wood. This step consists of using the Gemini Restore A Deck Kit. This kit contains both a Step 1 Wood Deck Cleaner and a Step 2 Wood Deck Brightener. The Step 1 cleaner will help remove the dirt, graying, and mill glaze from the wood while Step 2 Brightener will neutralize the cleaner and help restore the natural color.

Staining New Wood and Decking for the First Time

Even after the waiting period and the proper prepping, new smooth wood is still not as absorbent as it will be in a few years. We strongly suggest only applying 1 coat of the TWP Stains the first time. Do not over apply as the TWP may not penetrate into the wood correctly. Make sure to back wipe any excess stain that does not penetrate properly into the wood after 30 minutes. For new smooth wood, the TWP 100 Series if allowed in your state, otherwise use the TWP 1500 Series.

Maintaining TWP Stains

Apply a light maintenance coat to the flooring in 9-24 months. If just slightly dirty prep with soapy water to remove grime and reapply one light coat. If you wait 18-24 months make sure to prep again with the Gemini Restore A Deck. After the first year or two, your wood will be able to absorb more TWP stain which results in a longer stain life and protection!

Tip:

TWP is a penetrating wood preservative. It performs properly when it penetrates 100% into the wood. Over applying will not result in longer protection.

I used TWP 1516 stain on a rough cut cedar pergola 1.5 years ago. I was gonna put a tinted plastic top on it so we can add a fireplace and furniture — it gets HOT down in central west Alabama. It’s been stained abt a year and half, I have been noticing a black color on the sides of the 6×6 posts and also the rough cut 2×8’s on the top. It looks like mildew and it’s all over. I went up to add some 1x’s for the plastic roof and noticed that a lot of the stain is… Read more »

Hi, my question concerns new 16′ x 28′ decking; mine was built in July 2020, however the steps are reclaimed pine decking boards, from my previous deck. The underside is now face up, have been pressured washed and look pretty good, not too dissimiliar to four month old boards, a tad but not too much. 1) Is it too early to clean, prep and stain, if so, when..I live in East Tennessee? 2) Should I only apply one coat of stain to the new but two to the older steps? 3) My kit arrives this afternoon, so I have not… Read more »

I am in Michigan and had a new deck installed in May, with cedar railings and pressure treated floor decking, currently unstained. I have an opportunity to stain the deck now (early November) as we have a stretch of warm days (60 degrees plus in daytime) with no rain. Do you recommend staining now, or waiting until spring? I was originally thinking to get it done before winter to protect against the harsh elements.

I’m just finishing a deck with cumaru hardwood and will let it sit over the winter.
Will it oxidize enough under the Minnesota snow to apply twp 100 next spring?

I have purchased the TWP pro 100 stain for my fence. They are round fence posts placed in the ground with a single vertical round post between them. The posts have been in the ground from 1-3 months. They were purchased from Tractor Supply and Lowes. We need to get them stained before we put the wire up on them. I am not sure how to tell if they are rough sewn or not. Do they sound ready to stain? Thanks!

We just had a cedar wall put up on our new deck. We want to stain and seal it with the rustic 1500 series. Reading about prepping we are getting that we are supposed to let it weather for many months first? Help!

I have a one year old (untreated but now weathered) deck, ready to prep and stain. I used the two part Gemini kit, and with the help of a pressure washer (w a 40 degree spray head, held at least one foot off the surface at an angle) I was able to remove quite a bit of oxidation. I was careful not to gouge the wood. The Gemini kit really brought the deck back to life yesterday! But today I’m dealing with really fine fuzziness – it doesn’t seem to be the wood fibers, but it’s patchy here and there… Read more »

Hello, I’ve built an outdoor table from western red cedar posts cut to 3”x3”. Posts were in an outdoor but shaded lumber yard for the summer, then in my garage since August. I routered all edges and then sanded posts thoroughly with 60 and 120 grit sandpaper until outdoor-furniture smooth. Table has been finished for a couple weeks, but should the wood still be left outside untreated to weather for the Canadian winter? It feels like the wood will get pretty waterlogged….

I did the cleaner on my 4 month old 14 X 28 cedar deck this weekend (tested approximately 10 locations with a two probe moisture meter and it averaged 13%). As the cleaner sat on the deck for the recommended 15 minutes I noticed a film forming (mill glaze coming off?). After pressure washing it still felt somewhat slimy. I then used the lightner and rinsed it off with a hose after 15 minutes. This morning the deck was dry but extremely blotchy with a white coating and cedar color coming through. I attempted to pressure wash it again with… Read more »

I received RestoreADeck containers for my project. Both containers indicate contents to be 2 pounds or 32 ounces for 5 gallons of mixture. I weighed each container and they only weigh 30.8 ounces. Is that sufficient for 5 gallons?

Replacing 18 window frames and trim in Maine on a lake (water front) property. All the new wood is pine. I have not installed the glass and glazing yet. Assume I have to wait the 4-9 months for new wood. Should I install the glass and glazing now or will the prep affect the new window glazing? Would the pine wood weather if I stored the frames inside or should they be exposed to the elements? Do you suggest a 1500 product?

I cleaned my new deck boards with Step 1, The area which was underneath an umbrella stand is still noticeably lighter than the boards that were exposed to the sun. Shouldn’t the cleaner have lightened this area? I also noticed some green straks on someboards. Again shouldn’t the cleaner have removed these streaks?

I built a new deck with treated pine, it weathered for 10 months , I used a cleaner and brightened prior to staining. I used Twp natural 1500 stain In February 2020 , just one coat and it absorbed great.. I need to clean and put second coat on prior to winter…. what cleaner should I use? And should it use a brightner with the cleaner again or just a cleaner ?
