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 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.

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.

We have a brand new covered deck that is 12×16. The deck faces south, however, the only part that is truly in the full sun all the time are the stairs. I read a comment regarding never stain in the sun or maybe the intent was the sun at the heat of the day. Can you expand on that and give some suggestions of when to stain the steps. The deck was installed on a new build in December of 2020. Would it be best to wait until fall to stain it? Thanks

For staining new smooth deck boards, on May 8, 2021 the TWP Help adviser expressed a preference for using the 100 Series instead of the 1500 Series if allowed. Does the 100 series have some advantages that the 1500 does not?

I live in Oregon so there should be no restrictions. So with everything being equal, why is the 100 series better than 1500?

I am about to install “new” cedar siding, but it’s been sitting in a shed for almost two years. Does this age it enough to allow 100 to be applied without other prep?

Does it make any difference that all the cedar siding is kiln dried? Thank you.

I have finished the cleaning and brightening yesterday, this is my first time doing this.
I am noticing a lot of white spots on my cedar boards, especially around the knots, and I am sure I did not miss all those areas when I was cleaning. I am going to try and send a few pictures. 

I couldn’t figure out how to send a picture taken with my Iphone, which I have done before

I am not sure this is going to stain and look good when I am finished

I finally got these pictures to sent to your site. I guess I didn’t see your reply above, and I sanded down all the “white spots” yesterday, with the hope of staining today, and now I see rain in the forecast for today, so I may have to wait. How long do I have to wait for a good day to stain without doing any prep, except maybe for taking my leaf blower to my deck………………

I called the phone # on this site Saturday morning after 8am and talked to some lady who could not answer my question, and gave me the company phone # to call, but on a Saturday I didn’t expect you to be open, let alone the company I called after talking that answered my phone call

I am going to clean my new deck with your gemini products, and I have a 2 gal sprayer, and I am wondering what I should clean my sprayer with after I finish cleaning, before I put the “Brightener” in the sprayer container.
(This may be a duplicate question from yesterday, sorry)

I’m planning to add a 2×4 cedar toprail to the posts of a new cable system. The cedar is clear (no knots) and kiln dried. Given it’ll be probably a few weeks old, should I still treat it as new and install then wait 4 months before giving it a single stain even though it’s kiln dried? Many thanks.

I have a cedar deck in upstate NY that is about 15 years old. It has been stained in the past with Behr Semi Transparent Latex Cedar color and prior to that with Cabot clear sealer. The Latex Cedar is peeling off the floor section. I have pressure washed it but some sections still have some remaining stain coating left over. Will I need to brighten and then stain with TWP 1500 or what do you suggest?

For the areas that are still in good shape with the previous Semi Transparent Cedar tone water based stain from 2 years ago (e.g. fencing, balusters, posts, etc.) can I just recoat with TWP 1500 Cedar color?

My unfinished cypress deck is cleaned, prepped and drying in 80°+ weather. It was built 12+ months ago so it is not new, just no finish. I assume one coat will be enough. In a year when I’m ready for another coat….
a) do I do the wet on wet or just one more coat.
b) do I have to clean and scrub the 2 step restore a deck process again or just lightly pressure wash and use some house wash cleaner.
I live in the rainiest county in the continental US in the mountains of NC. There will be mildew!! No way around it. Is there anything at all I can do to slow the mildew?

thats what I used. It’s all blotchy and frosted looking. I rinsed until I was getting too much pulp come up.
i hope it’s just dryness after the cleaning process washing the natural oils out and it will stain ok.
as I asked above when I put on another coat in a year, do I have to use the complete cleaning and brightening first or just soap and pressure wash to get off surface dirt.

Is the oxidation that pulpy mess that comes up when you pressure wash and scrub with a brush? I thought it might be bleached from using chlorine bleach on the mildewed spots which was the whole horizontal area….per the instruction on the RAD container. If it is dried or lightened from bleach will it blend with the stain or do I need to sand the whole deck?
we spent hours with the pressure washer getting the soapy first step of RAD off.
we used Jomax first to try and get the mildew off. Didn’t work. Then the cleaner….didn’t work, then chlorine mix…worked ok, then the neutralizer/brightener, then lots of rinsing. It’s covered with a shade cloth so it didn’t dry.

We recently had our deck sanded down from a solid stain and went with semi transparent dark oak stain. We allowed it to dry for 4 days. We had our first bbq outside on it. Immediately after, we noticed significant scratching from our poly wood furniture set. Did we do something wrong? We didn’t have this problem prior with the other solid stain.

Can you elaborate on the comment “sanding could be the issue”? Was it not sanded enough or sanded too much? Not sure how we could’ve sanded differently.

I am building a deck with BROWN pressure treated lumber, with the top decking done in Trex and the railing done in black metal. First: Do I even need to treat the vertical understructure/posts/joists if covered by Trex? Second: If so, would any of the products with a tint even show on the darker brown PT lumber? (I’m in Payson, AZ- 5500 ft, dry, alpine like environment, but with monsoons in summer and sometimes snow in winter.) Thanks!! 🙂

In response to a couple posted questions it was made clear to never stain all sides of wood. The wood needs to breathe, not be 100% encapsulated. That would cause dry rot. How does this standard apply in regards to staining a wood fence? Leaving anything unfinished or unprotected seems counterintuitive to me.

The fence was built using pre-built framed panels. The pickets in the panels all sit in a channeled bottom rail which seems like it would share the same concerns you noted with the wood decking (horizontal, close to ground, unable to breath properly). Would the bottom rail then require a different approach to coverage or application of stain than the rest of the fence boards would?

By not staining/sealing all sides, don’t you need to be concerned with differing expansion/contraction and absorbtion rates, which may lead to permanent deformation in horizontally installed boards, such as “cupping”?

I have a lean-to porch with a tin roof. I was supposed to clean/brighten 2 yrs ago but health issues arose. Now, I’m preparing to start this project. I have a couple of boards that are rough and need sanding. Also stamped labels on the wood in several places. You recommend sanding first then do the Gemini routine?

I recently redid my western red cedar deck and installed metal balusters. They look great but I see that the RAD product can harm metal. Can you recommend another product for cleaning the railing that will not harm the metal balusters?

perfect so no additional items needed as a sealant.

This sentence (see below) from FAQ should it say “as it does NOT have mill glaze…”?

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.
