Prepping New Wood For TWP Stains

TWP Stain Tips for New wood Decks in 2020

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. Use the 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.

We built a new deck in November 2019. The horizontal boards have dried considerably and are very light in color compared to the railing, steps, and privacy fences. Can the horizontal boards be cleaned and stained now and the rest of the railings and steps done later in the season after they have weathered more? If so, will cleaning the railings, steps, and fences affect the horizontal decking if the cleaner gets on them? And can rinsing the cleaner be done with a hose rather than a power washer? Power washing makes me a little nervous afraid of damaging the… Read more »

We built a new cedar deck 2 years ago and stained the deck with 101 Cedartone to quickly (about 2 months later). The stain did not penetrate the wood and would rub off if you applied any pressure while cleaning. We hired a company 1 year ago to come in and they power washed the deck and applied brightner saying this would solve the issue and remove the mill glaze. The company stained the deck using 101 Cedartone but we have run into the exact issue where the stain did not absorb into the wood (see pictures). Should we have… Read more »

California fence – additional question. The rough sawn cedar I described for building the fence is going to be used to picture frame panels of galvanized welded wire, 4 gauge. Will the stain, strippers, or brighteners adversely affect the galvanized wire?

Thank you.

I just installed a new deck that is redwood. My deck is partially covered and faces south east. After inspecting the wood, it’s easy to see it was last years cutting as the wood is already quite dry and I live in Colorado so I’m dealing with humidity levels in the 20’s. The uncovered portion of the deck is already fading. Water dropped on the deck readily soaks in both on the covered and uncovered portions. Given these conditions can I shorted the wait period and stain the deck 3 weeks from now?

This is a two part question: Question one: I applied TWP 100 to my cedar fence two years ago. There is some fading in the areas with high sun exposure and would like to apply another coat of the same stain this year. Would pressure washing be sufficient prep or do I need to use the Gemini cleaner? Question two: Two years ago I had a new deck installed and per your recommendation, have let it “age”. This year I would like to apply the same 100 stain to the deck as the fence. Will the deck also need the… Read more »

I just read your instructions on prepping new wood before staining where you suggest waiting 4 to 12 months before staining. However, I have read some recommendations that it is good to treat or seal the backside of of the wood before installing. What are your recommendations??

I have waited over a year and ready to clean and stain my deck. It is pressure treated pine. Some areas are splintering and I want to smooth with a orbital sander. Will I need to wait for the color to match the outside on sanded portions or should I sand the entire deck? Any other tips on preparing deck by sanding prior to staining?

Hi- I am getting ready to install a new rough sawn red cedar fence but its winter here in Utah, temps in the 30’s currently… I have metal posts already installed and will be installing horizontal cedar 2×4’s into a track welded onto the side of the posts… am I better off to apply the stain in the garage (where I can keep it warmer) then install the boards, or install the boards now and wait until spring to apply the stain… is 1500 the best product for my application? Hoping for as clear and natural finish as possible on… Read more »

I am afraid I already know the answer, but—can I stain 1″ pine trim (fascia) boards before installing them. It would be about one hundred times easier to stain them while they are on a sawhorse on the ground rather than when they are 40′ up in the air. Plus, obviously I can’t stain both sides, which I’d like to do, once they are installed. I can sand any mill glaze off before using the stain, Thanks.

We’ve got newly installed KDAT that flows from a covered screened porch out to a small grill deck. Deck is uncovered. What product should I be looking at if I want the color to remain the same throughout (recognizing that the uncovered will fade faster)? To complicate things a bit further, we’ve also got french doors made of fir that lead out to the screened porch. Would like to stain those as well.

Thanks for the help!

Your product has been recommended for a cypress trellis system. Wood is kiln dry could product be applied immediately or still need 4 to 12 mouth before application?

I’m currently putting up new pine log siding on a garage, located in Massachusetts. The siding is kiln dried and so I’m wondering if I still need to wait 4-12 months after installation to let the moisture content drop before staining it. I plan to stain it using TWP200 series since that is what the rest of the log house was stained in last year.

Have a new deck (9/2019) and want to protect for the MI winter. Planning to use Thompson’s Advanced Water Seal now and then TWP in the spring/late summer. Any problems with applying TWP after using Thompson’s Advanced Water Seal?

So things did not go so well this weekend with trying to get deck done. Rain did not cooperate. So as it stands now, today is 2 weeks since I completed Gemini prep, so I know I will obviously have to do it again before staining. So here are my questions: 1: Do I have to clean and brighten, or can I just do brighten? 2: Since I have already cleaned and brightened, have I stripped the pressure treated pine of its protection layer, and does that mean that I HAVE TO get the stain done before winter arrives? Or… Read more »

Hi! I am using rough sawn cedar for my house shutters. I live in Colorado where the sun can be intense with the altitude, and I also live in the dry/farmland side outside of Denver. After reading the options of the TWP 100, 200, or 1500 series, I am having a hard time deciding what series would work best for the rough sawn cedar. Also, what is the best way to apply to apply to rough sawn vs smooth board? Is it still the wet to wet method? Would the stains also cause any runs on my house paint once… Read more »

Hi, I got a new pine fence installed early June and I’m looking to stain with TWP1500. I live in North Carolina and it has just now dropped below the mid 90s, but it has now swung to 40s/50s overnight. Is it ok if I prep and then stain while it is in the 60s/70s during the day, but possibly 40s at night?

All of the top rails of my deck were replaced, plus some horizontal boards and steps. The deck was cleaned and pressure-washed (not the new boards). There are some places where sanding needs to be done. Is it okay to wait the 4 months to stain the entire deck? Sand now or before staining? I’m just worried that the old wood won’t be treated for that long of a period. Thank you.

Im sure its been covered but I’ll ask again. Applied the cleaner and brightener a few weeks ago. Rain has been horrible and not giving any breaks, finally have a window of dry weather this coming week. Do I need to clean or brighten again or both? I believe you recommend 2 weeks but will 3 weeks really make that much of a difference? What would happen if it’s not properly cleaned?

Mike

Ok. So I started the cleaning portion of the Gemini kit last week doing what I could every day after work and finished cleaning Saturday. Unfortunately, I came down with flue and could not get to the brightener step. How long after cleaning should the brightener be applied? Is it necessary to do the brightener immediately after the cleaning? I’m hoping to get to it this weekend.

I recently installed Douglas fir (not pressure treated) deck boards on my covered porch and I am starting to notice speckles of what appears to be black mold. We have had a lot of rain here recently in Wisconsin. I am concerned if I leave it unfinished until spring as recommended by TWP application instructions that the mold will continue to grow and that it will permanently stain the wood. Should I apply TWP sooner to prevent it from spreading or will the Gemini Restore-A-Deck Kit remove these black mold speckles?
