Prepping New Wood For TWP Stains

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.

TWP 200 / 206 russet brown applied a week ago. There still seems to be an unabsorbed film of stain in some areas. How do we remove? Do we simply wipe the deck down with rags?

Please explain when and why staining all sides of lumber is not recommended. I am specifically interested in this subject as applied to decks, but also to general construction where back-priming may be used to improve the life of wood details.

I am confused. I applied the first coat of stain on my new cedar deck last september. According to the above directions I should just need to clean with soapy water rather than the Gemini kit and then apply a light coat of the same stain. Is this correct?

As I said in the first comment, the first coat went on in September. Other than some unexplained small stains from an unknown contaminant in a focused area the deck is pretty clean. YOUR directions say 9-24 months. Is this just a SWAG (sophisticated wild ass guess) on your part or from years of experience and testing. I don’t want to risk more fuzzing and have to sand the entire deck down again before the second coat.

I have a deck that I have stained every year for 4 years with TWP 1500 series. After a few months every time the horizontal surfaces that are in the sun have faded but the areas in the shade look perfect. We are also putting a pool next to the deck this year. I am wondering what stain I should use instead that will last longer and what prep I will need to do to be ready to switch stains. Will I need to sand the areas that still have full stain?

I am rebuilding a deck so I have the deck boards and can easily apply stain to all 6 sides prior to installation. It is 3 1/2″ thick by 6″ wide laminated cedar. I have sanded all 6 sides with a 220 grit paper to remove mill glaze. I do not know for how long the decking existed after being milled, but it’s surely at least a few months. Can I apply two coats, especially to the sides that will be hard to reach once installed, and should it be wet on wet or two separate coats allowing complete drying between coats? Any help you can provide would be appreciated. Thanks.

So if I stain 5 sides (leaving the underside of the decking raw wood), and then stain the underside in a year, would that be good? And again, should I do two coats, especially on the sides that will be nearly impossble to get at after installation, and if so, should they be wet on wet or dried between coats?

I have a cedar dock that we purchased last year. I let it season for 1 full year(6 mos on the water, 6 mos in my garage in storage). I took the dock sections out of storage yesterday and finished step 1 and 2 of the Gemini restore a deck kit. After 1 day of drying in my garage the cedar looks pretty good but it still has a light layer of “fuzz” from the gray wood fibers that we removed. Should I do a light sanding to remove these fibers before staining with the 100 series? Is it common to have this issue? Thanks.

Hi- I had a cedar fence installed about a month ago. One side of the boards is rough sawn, the other side is smooth. From the article, it sounds like I can stain the rough sawn side immediately without prep? It’s not clear to me- on the rough sawn side, do I apply one coat or two? Finally, I want to retain the natural color of new cedar as much as possible but protect against UV rays. Would that require the “CedarTone” color, or “Natural”? I’m in California- I assume I need the 1500 series, but the 200 series looks like it might be more transparent. Which do you recommend? Thank you!

Okay, just ordered 3 gallons of 1504. I have a 12×25 pressure treated deck . I’ll be staining the horizontals only for the first time. By the time the weather here is stable warm/dry enough for staining, the deck will be just shy of one year old. If I’m collating your advice correctly: prep first, allow to dry, then ONE coat this year?

Any recommendations for staining Cypress on a front porch ceiling, siding, and soffits around the whole house? We are deciding between Pecan and Natural and hoped to have a less “stripey” finish. Can you tell me more about when to stain the wood? (Is there a chance that the wood is not new and is stain ready or is that the way it comes from the distributor?) Thanks!

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 peeling/flaking off which I was not expecting after 1.5 years. I waited abt 6 months to stain, maybe 9, but it shows that you can stain right away on rough cut lumber so this should not have been an issue. I’m hoping this black mildew or whatever it is will wash off with a pressure washer. Any ideas or instructions you have that will help me out? We used the Rustic 1516 and we are afraid if we add another coat when we get it cleaned it may make it to dark. Can I use the clear stain to go over when I get cleaned and possibly may have to stain with a lighter color to fill in all the spots that is peeling. Please help and thanks for any help.

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 seen the prep instructions yet – do I need to power wash the entire deck before I began the prep? Any and all help is appreciated.

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 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 (pics attached.) It seems to come off some w a little leftover cleaner and a stiff nylon brush – but at 400 sq/ft I don’t necessarily want to hand scrub the whole thing unless it’s absolutely the only way to go. Should I pressure wash it again and then stain? Or pressure wash and repeat clean and brighten? Or sand it off? At a loss on this, but want to get it right. Any insight would be greatly appreciated!

Thanks for the quick response! Will I need to apply a new Gemini kit after that, or should a good water rinse do the trick?

I used TWP steps 1 and 2 on my deck. (The Gemini cleaner & brightened) There is now a green tint on parts of the wood. What do I do to fix that? It is a new deck about 18 months old and never been stained before.

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….

It is new. It was installed the past June. I pressure washed it yesterday.
I’m not sure if rough or smooth. It is pressure treated dog ear fencing. Not sure if that helps.
