TWP Stain Tips for New wood Decks in 2024

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 not 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.

Tips for TWP and New 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!

TWP Pro 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.

Do I need to wait to apply 1500 honeytone to my cedar dock. I bought the boards last summer and stored them inside. I just sanded top with 60grit sandpaper to remove planing glaze. I made 4′ x 4′ panels to install on aluminium frame dock and panels have not yet been outdoors.

I am replacing deck boards with red cedar. I have been told to wait 3 months, stain immediately, wait until water is absorbed and not beading.

My plan was to use TWP 100 Pro series on the deck boards. Now that I have researched both on line and at lumbar yards I am confused.

Thank you in advance for your assistance

I have 2 new marine-grade treated pine decks totaling about 600 sq ft (well, 7 months new); have purchased prep kit and TWP 101; question is this: It’s Friday now and I’d like to go ahead and clean/brighten today or tomorrow. Some weather possible Sunday-Tuesday but clear skies for days beginning Wednesday. Is it okay to go ahead and prep this week, and then plan to stain in about 7-8 days, with some rain possible between now and then?

Good morning,
We used the TWP 1500 series to stain the cedar post and shingles, and pine ceiling, on our newly constructed front porch. The porch weathered for 7 months prior to staining. We were wondering if we can/should coat the pine tongue and groove ceiling with a satin or gloss finish to enhance the look of the wood.

It took us 3 months to complete the rebuild of our Redwood deck in the San Francisco Bay Area due to being out of town and doing the work ourselves. The deck boards and steps are now 3 months out and had about 6 weeks of that time at 100 degrees in a full sun hot corner of the property and are visibly a bit shrunken and very dry appearing as evidenced by the grown spaces between the planks. The railings with the 4×4 posts were just completed last week. We did not buy all the wood at the same time and so it has not all been weathering together outside – the railing has more of a new wood appearance currently than the deck. Yesterday I cleaned and scrubbed all including the railing with Oxi-Clean, fully rinsed and followed immediately with oxalic acid crystals mixed into water and applied with a sprayer and again thoroughly rinsed. All is looking beautiful. My plan is to put the 1500 stain onto the deck boards tomorrow (as my husband does not want to wait) if the weather continues dry but not to stain the railing and posts for another 4 months. My questions are: 1) have we waited long enough to weather the deck floor boards 2) will I need to re-clean and re-brighten the railings and posts in 4 months (in March) 3) if so, will it be necessary to protect the already stained deck boards for the rail re-cleaning & brightening 4) will I then be able to get all areas on the same schedule with a second single coat after just a simple cleaning probably in 11 or 12 months?

Hi advice please- porch-roof-over-screened / cement floor (not level). Climate-Daytona Beach=humid-mostly hot-today-cool-60F. My experience with a log home and decks in hot/humid/wet climate is mold. Have used expensive log home water based and oil based deck stain. New PT framing to level. Using (NOT PT) T&G yellow pine treating under boards pre-installation with Borax in boiling water rolled on for bugs. T&G edge nailed with SS nails. Due to condition of new boards I will sand top after the install with 60-80grit then roll on top & edge with Borax/boiling water/roll-on. I will need to lightly wash loose Borax residue. I would prefer a water based penetrating stain – color choice grey. Bought Behr – tested on a loose board and did not like how it looked – tough to make even & bubbles unless wiped after painting.
ADVICE ?? Stain after Borax, air dry, quick wash, air dry, sand 80 grit, quick damp mop wash ?? STAIN SUGGESTIONS … THANKS

Hi. We just had a new large deck with a couple of levels built with premium pressure treated pine. We live in Memphis, Tennessee which is on the Mississippi/ Tennessee state line. It is hot and humid and this summer we had a lot of storms. We get snow or ice maybe twice a year in the winter. Our deck is not covered. How so we tell when it is ready to be stained and which type of stain would be best when it is ready to be done? Thank you so much! Also, do you have small containers to buy so we can sample a few colors?

Deck with new lumbar was built June 2021. Waited and applied TWP 1500 June 2022. Looking to do the final coat this month. It was pressure washed with water only three months ago.
1- Do I need to pressure wash again?
2- There has been a lot of fading in the first coat since last year…especially the deck boards compared to the railings. With this second coat, will it finally retain its color?
Thanks!

For the cleaner and brightener, does the deck need to be dry or can it be damp or wet?

i stripped deck with your stripper and then did the brightener step. After that i let sit a couple of days and cant believe the white buildup of i think oxidation. I went to all the work of sanding and when i got done there is still white in the wood grains. ( i sanded with 80 grit mainly and some 60
my question is look at the picture and can you tell me what i did wrong that i should have so much white stuff on the wood. it is cedar as you can see the white and the part i have sanded

Done sanding and of course some rainy days ahead
? 1 do i apply brightener know and then seal when i have a couple of days with no rain
? 2 when i apply i am only to do 1 coat right?
? 3 in between the boards there is still sealer that didn’t get cleaned and it is a little scalely can i leave that and not have to worry about it peeling
? 4 does twp have a site that actually shown the processes and problems that come up like this or is there a stain deck forum that people have the opinion on what to do etc
Thanks you in advance for your advice.
By the way when the wood gets wet it looks beautiful

I have a new pressure treated deck and pergola in Tulsa, Oklahoma. I know to wait several months for it to dry. I’m thinking Spring as it’s August and temps are in the triple digits here now. I want to know three things 1. Would it be a good idea to use the Semi Solid Maximum UV Protection? (I ask because everything I read here seems to indicate I should use TWP 100, but I like the idea of that extra UV protection) 2. Do I use the same product on the pergola as the deck? 3. Are you aware of local contractors that use TWP products or will allow me to purchase for them TWP products to use that I can hire to do the work as I am not physically able to do it?

ok thanks but the one thing i cant get over is how much white stuff after i stripped and did the brightening. it was very excessive and the grains stood up so high it was all over and hard. i cannot believe i could apply stain with that much showing . i would like to know could i have gotten by without sanding or did i do to much pressure washing and should i have just used a standard hose to clean and had better results.

Hi,

We live in Missouri and have Western Cedar rough sawed beams that we just installed to support our second story porch/deck. These beams will be exposed to the weather. We don’t have to let these weather, correct? What kind of stain would be the best? After staining do we need to apply some sort of protective coating?

The deck of our porch is smooth treated pine. Do we need to let this weather? Then can we use the same stain as we used for the cedar beams? Does it need a protective coating?

Thanks!

Hi, I’m using new #1, eased edge kiln dried cedar decking. Can I just start with 1 coat I’ve read all the new wood installation, but I would like to pre stain befor install,,, not deck it and let it weather first before staining. I guess I’m just a little confused. But I do understand I need to test to see how well it’s absorbing first.

We cut cedar trees and had milled last year (2x6x16) for a new deck. Current Mositure level at around 8%. The deck was installed last month. Because it is a rough hewn wood product do I still need to wait 4 months before staining? I’m concerned because we will be entering rainy season (we’re in the Pacific Northwest) and will likely not have a chance to stain until next year. Would like to get, at least, one coat on. Also, the cedar planks look a bit rough and we were thinking of sanding using a 60 or 80 grit – what would you recommend.

We had our own lumber cut by a Wood Miser portable saw mill. It has been curing for over a year now in the humidity that it will be installed in for a deck.
Does it still have “mill glaze”? Is it technically “new wood” even if it’s been stored outside under cover (so minimal UV exposure) but with full air circulation?

I am building a privacy fence from new planed western red cedar that has been kiln dried. Do these boards need any further prep before using an oil stain. A test board produced shiny areas where you see the grain. Is this inherent to the board? I have tested by sanding with 120, 100, and 80 grit and still the same effect. Any thoughts?

I’m ready to stain my deck with a maintenance coat. It’s been about 3 years since last stain. I cleaned, lightly sanded to get off the fuzzies and brightened. 2 questions. 1. is it best application to use a stain brush or stain paid. Or do I only use a stain brush if spraying on the stain, which I don’t plan on using unless it is recommended. 2. I plan on 2 coats since this deck is cedar and is 5-6 years old and this will be the 3rd time staining.
Thank you

When you say lightly clean and add another coat do you mean do the clean and brighten steps again or just a power wash clean without the steps 1 and 2 restore process

I just received new exterior fir doors for my home and am considering staining the outside of them with TWP 1500. The siding on my home is 45 year old redwood T-111 and also needs protection of some sort and I was thinking of the same TWP 1500 stain to be somewhat uniform. Question: would I need to install the unfinished doors and wait the 4-6 months recommended above before I stain the doors or can I go ahead and stain the outside door and door jamb now before they are installed? (The inside of the doors and door jambs will be painted.) And, would I still need to use the Gemini Restore A Deck on the new doors’ wood if I can stain them now? I’m assuming I would need to use the Gemini on the older siding even though there is no product on the siding…it is naturally aged for 45 years.

Hello. I just put TWP 100 Series 1 Gallon Stain Color Dark Oak 103 on my deck. The stairs were recently rebuilt and I let them age for about 9 months. I only put on one coat as directed. They are now lighter than the rest of the desk. My question is how long I should wait to put a second coat on them.

I am planning to stain my two year old pressure treated deck which has never been stained. It is very large (3500 sq ft) with two covered portions along with an uncovered pool deck. I am in Pittsburgh. Would I be correct in ordering 5 Gemini kits and 100 series – 36 gallons (two coats wet on wet)? Am I also correct that balusters only need one coat and undersides of deck do not need to be treated? Do all areas which have been stained with a sprayer need to also be wiped with a stain pad including balusters? How long before finished deck can be walked on/handle rain? What is the time frame to stain after Gemini treatment? Thank you.

I cleaned and brightened my cedar deck last night using RAD along with a broom and hand brush to get some of the gray and what not off the surface. I previously did this 3 years ago but mistakenly used a pressure washer which resulted in me having to painfully sand off all the white fuzzy stuff before applying TWP 100 clear.

The attached photos are 16 hours post cleaning and brightening… The deck looked beautiful when it was wet last night but now appears to be a bit white/gray and some fuzzy stuff in areas..Planning to use cedar tone 101 this time for the UV protection. Do I need to sand this thing again or will it turn out ok even though its looking pretty dull post clean?

This doesn’t look kind of off white/gray to you? Last time after i prepped and sanded the wood was almost red/yellow looking which is what I was expecting this time.. I’ve got a few fuzzys again too. You don’t think I should sand this before putting down 101?

Ok so I ended up doing a light sanding with 80 grit to clean up the fuzzy stuff and all looks good now. Unfortunately we got around a tenth of an inch of rain over night and we have a decent chance for rain again late tomorrow. I was planning to stain this evening. Today is going to be 85, sunny and windy most of the day.. Think I’m still ok to stain this evening given the low amount of rain and weather conditions today? Most of my deck is covered so we are really just talking about the stairs having got a light rain. surface is already dried visibly. Second question, now that I have sanded after doing both cleaning and brightening + the little rain, do I need to brighten again before staining?

Greatly appreciate the help here!
