Staining New Wood with TWP Decking Stains

TWP Stain Tips for New wood Decks in 2019

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’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.

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?

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?

Hi, I’m in Connecticut & about to strip and stain a 15 year old deck made of pressure treated wood. Four questions: #1. I’ve replaced 3 boards on a 400 sq ft deck with new ones straight from the lumber yard. Can I strip & stain or do I need to wait out the winter? If I can stain, should I treat these boards any different – maybe only apply 1 coat? #2. Can I start stripping even if the deck is damp from recent rain? #3.

1+ year old pt pine deck in the NE. Used the gemini cleaner and brightener along with the hose and a deck brush. Got a lot of fuzzies and some super light gray spots i didn’t get brushed entirely off.

Lightly(?) sanded the fuzzies down with palm sander and 60 grit, and took some of the gray off also.

Can I stain after 48 hours? Or do I have to wait for this all to reweather because of the sanding? Will I have to buy another gemini kit and do that all over again?

Thanks in advance

New redwood deck built 5 months ago (in April 2019) in San Jose, CA. The redwood was not kiln dried and is clear (no knots). It doesn’t rain in this area from mid April to mid Oct. Is it better to stain now after 5-6 months, or wait until next spring after the rains stop? Our deck is on the south side of the house so it’s had 5 months of hot sun every day. The current color is slightly darker than when newly installed and no greying yet.

My deck is pressure treated pine and has been stripped, sanded and will be cleaned prior to staining. Part of the deck had to be replaced with new pressured treated pine and has been weathering from 4 to 12 months. Your application instructions call for only one coat on new wood. should I use one coat for the entire deck and wait 12 months for the second coat?

Two questions about brightening: 1) Will it be OK to do the brightening step a couple of days after cleaning? We’re prepping cedar, new construction, seasoned for 4-1/2 months. (We started the cleaning step today, but rain is impeding our schedule re. completing Step 2.) 2) Will the BRIGHTENER have to stay on for 15 minutes, like the cleaner? The container instructions don’t say anything about leaving it on for 15 minutes. It just says to spray it on and rinse it off. It sure would speed things along if we didn’t have to wait so long.

Good morning! We’re getting ready to clean/brighten our cedar deck & railings. It’s a new construction, weathered for 4-1/2 months. I know we’ll have to make sure the wood is fully dried (2+days) before staining. There’s a “chance of rain” every day during the next week. So for staining, we’re going to be waiting for a window of opportunity for when the wood is fully dried and no rain in the forecast. We would really like to get this cleaning/brightening step done so that we can hit the ground running with staining when the weather is right. If we clean/brighten… Read more »

We are in the middle of prepping to stain a new deck and railing to get it ready to stain. The deck is two years old and has not yet been treated. We have just used the gemini restore a deck and as the deck boards and railing have dried there appears to be a whitish film on all the boards. We have not yet used the brightener. What is causing this and what should we do? Can we just go ahead and apply the brightener and then stain? We are puzzled by this result.

What is the best range of moisture content in cedar boards before applying stains. Website states to weather new wood because of moisture content. Im using kiln dried wood and do not understand why i should let it be exposed unprotected for so long before staining. I could not find ideal moisture content ranges anywhere. Is it a bad idea to apply a light coat if the wood is already dry enough? I plan on using 100 series.
