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.

I have a large wood work of art that I plan to hang on my fence in a generally shady spot in my garden in the Bay Area, where we have mild winters but frequent foggy mornings. Which type of TWP oil should I use, the 100 or the 1500? This is not a new piece so I’m assuming I don’t need to follow the directions for new wood. Is that the case?
Thank you

I ran out of the deck cleaner but still have the Brightener in the sprayer, can I still use it while waiting for the deck cleaner to arrive? How would I know that the Brightener has completely washed off? Ty

I have a newly installed (less than 30 days) cedar fence. The pickets are rough sawn cedar, while the rails and posts are smooth pressure treated. How do you suggest we prep/stain? Should we do the pickets now, then wait min. 4 months to do the rails and posts?

I live in Florida and had a large deck (650 sf) redone 4 months ago using pressure treated pine deck board.
1- Will pressure washing it help with prep?
2- Do I need to stain top and underside for wood rot protection?
3- Any recommendation of 100 vs 1500 stain for new decking?
4- Can I get a couple of samples to decide on color?
Thanks,
Charles

Comment on the efficacy of staining all four sides of the deck boards before installation vs. waiting
4 -12 months and only being able to stain the top surface.

Thanks!

Can we stain the vertical posts and railing 24 hours after a rain? It is 88 degrees today deck is in full sun. We are using the Cape Cod, on a 16 month old pressure treated deck. We know we need to wait 48 hous on the horizontal boards.

Making deck railing from very large pallet wood that came from Ukraine. It is some type of unusual pine that is very dense and rough cut. Did not want to have rough surface so recently planed it all. The wood had been sitting in dry barn for over 3 years. Assuming from other Q&A we still need to allow the wood to dry for at least 4 months. Was hoping to stain prior to assembling. Is it possible to dry inside and not U.V. exposure?

Hi – i replaced a 300 sf section of dock that’s on a lake in NH with pressure treated deck boards, the boards have been weathering for almost a year now – is it absolutely necessary to prep with the stripper & brightener? i’m concerned about the product getting into the water after rinsing the decking off? the deck really bakes in the sun for good portion of the day and is really exposed to all the elements, so not sure if that aids in wearing off the “wax” mill finish. should i only apply one coat as it’s “new”… Read more »

I’m applying 1500 to an old stripped cedar fence (two coats). The can says to not apply if rain is expected within 48 hours, which is often hard to know, especially with thunderstorms. How important is this?

I recently cleaned and prepped a new deck. I waited 2-1/2 days before staining. Looked great. A week later and we had our first light rain. Now there are places that are white and feel sticky. What has caused this and what can I do about it? Thank you.

Installed a new deck 7 months ago. Purchased the gemini restore kit and the 100 series stain. Is it ok to sand down the spots where the screws made splinters in the deck boards before we clean and stain? Thank you

My 10-year-old cedar deck has been stripped, sanded and I plan to use brightener before staining with TWP 100. Since I sanded, is it considered “new wood” and I only apply one coat vs. two? Apply another coat next year or will I get multiple years out of one coat?

Can I stain new rough sawn cedar with knots soon after installation with 1500 stain since it is rough or do we still need to wait the 4 month or better weather dry out period? Also same approach regarding preparation for staining new rough sawn fir pine plywood siding. Also since both would be new wood do you recommend one coat initially or two?
Thanks

Sorry about this – asked this question, posted it, then lost track of where it was. 4-yr old treated pine deck of 2x6x8ft members. When new, stained with Rescue-it. Numerous boards have rotted. Replacing rotted boards with extra boards that have sat under a covered porch, then will flip the remaining deck boards over to the underside that was never stained. Do not have to install any new wood. Will use the Gemini Restore Kit prior to staining with TWP 100. Do I need to treat the deck as new wood, or can I consider it ‘seasoned/dry’ and proceed with… Read more »

I completed the first two steps using restore a deck kit. After drying I noticed there is wood fiber film on some of the boards (see photo). What do I need to do to fix this?

I purchased some 18 year old redwood 2×6’s for my deck. This redwood is quite dry but not weathered, been setting in shed. Seems to need minimal prep work but is probably dirty after setting so long. Small amount of graying on a few pieces but most have no graying. Nice heartwood color but not clear of knots. I am ordering 100 series either clear or redwood (probably redwood 102 as I want U.V. protection for south facing deck). What prepping do you recommend?

I am installing Western red cedar shingles on the gable ends of my home. They are smooth sawn. Would you recommend treating them prior to installation or would I need to wait months for them to weather? I was planning on dipping them to cover all surfaces.

Yesterday I cleaned my deck, about 8 months old since installed, using the gemini kit. Followed instructions and used a pressure washer for cleaning part and water hose for brightening step. This morning I wake up and find that a few of the boards have a green layer on them, I am assuming a mildew. At this point I am thinking the tempature was not high enough to promote fast enough drying. Is there something I can do to apply the stain tomorrow or what advice do you have.
