Prepping New Wood For TWP Stains

 

Staining New Wood with TWP Decking StainsWhen 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 stain manufacturer 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 cuts 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 the 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.

Deck built in January of this year. PT wood with tongue and groove non-PT ceiling in the covered portion of the deck. I bought dark oak 103 for the entire project. I’m wondering if cleaner and brightener will be necessary on the ceiling wood. Do you think the ceiling will look drastically different from the rest given the different types of wood? Can you send me a link with instructions on how to apply the cleaner and brightener? No pressure washing required if I use the Gemini kit?

I have a 10 year old mahogany deck previous stained with Cabot several times. The stain is dark and hides the grain. I want the grain back with new treatment. I plan to sand the deck as much/little as necessary to remove the current coloring, and then treat it with TWP Clear or some light stain. What should I worry about? (The deck is covered.)

By the way, I will be very annoyed if after sending this message, I get a lot of SPAM from your company. I will not buy your product if that happens.

I bought TWP 1500 Pecan. The wood on my back porch is 15 years old and has never been stained. Just treated wood. I power washed it last week-twice. But now our temps have fallen from the 80’s to the mid 50’s and 40’s at night with rain. I have a three day break from the rain. Is the three day break and these lower temps good enough for proper staining my porch with no overhang?

Hi. Well I got my deck stained Sunday but it was a bit hotter and more humid then I hoped it would be, so much for weather reports, so do I wait for 6 months or a year to restain by washing with soapy water (if it is needed) or prep it with the restore kit which I have enough left for another use as well as stain not used .Btw will the Restore-A-deck kit left over 6 or 12 mts be ok to use…Thanks for Your help….Mario

Hello, I just had a pine deck installed two months ago in the mountainous region of Boone, NC; lots and lots of moisture. With that said, I want to clean and stain my new deck using TWP products. I have read a number of your articles but I just wanted to be sure. Is it a problem if I clean (sap from a large pine tree and acorn stains from acorn droppings) and stain using cedar tone? Not sure if I should use 100 OR 1500 when the time comes. DO I need to sand the entire surface, railings etc?… Read more »

Hi.I understand the need to let P.T.wood dry out for a long time but what about cedar? The cedar Decking I used is dry (kiln dried) and 2 months installed now. Do I still have to wait 6 to 12 months? Or can I just use a cleaner and then stain it?

New cedar fence (rough sawn), completed in May 2018. Wood stored indoors all winter prior, thus fully dried on install. Has weathered all summer. Ever so slight silvering, no heavy oxidation and still retains natural cedar color. Ordered 10 gallon of 1503 stain. With this being a new wood install with very light silvering, can the fence be pressure washed only to remove dust and pollen, dried and immediately stained (brushed on, wet on wet). Or does brightening step need to be actioned. Confused on this step, as this is still new, un-oxidized wood.

Redoing our 12′ x 14′ treated pine deck. I have removed and scrapped the railing and top cap but left the four 4″x4″ posts. The flooring was in good shape so I have sanded it and the four posts (plus the upright beams and cross pieces) to remove all the water born stain that was on it. The deck is 15 years old but the stain that was put on was only on for 2 years. I did the sanding as I was told that sanding old wood helps reduce the penetration of stain which will be darker than on… Read more »

We have a store here in Cleveland, TN that sells TWP deck stain. Are you saying they are not selling genuine TWP products?? Perhaps they are placing an order with your online store for customers of their paint store. I will probably avoid any problems Once a 5 gallon can is opened how long does it store?

I pressure washed a cedar swingset 6 months ago and put some of the parts in my garage to stain. I had a back issue and was unable to do the project. I sanded all the parts in the garage using 100-150 grit orbital sander and after reading here, i am afraid i should have left it to weather some before staining. I already stained them with TWP100 rustic. It absorbed pretty good and took 3 or 4 coats before it stopped absorbing and was wiped dry. The frame parts are completely dry now in my garage. It looks great.… Read more »

Thanks for your quick reply. additional question about 2. : for the old wood, after sanding it to remove old paint , isn’t it preferable to prepare it with RAD and stain it with twp 201 (cerdartone) which i just bought also ? I feel it is not really good to keep the wood sanded without any protection.

We just installed a new KD cedar deck. There are a few rough places between boards that we wanted to sand down and smooth out. If we sand a few select places on the deck, will we need to go over the entire deck with a light sand paper to even it out before staining?

We are expecting a pergola kit this week. It’s kiln dried Western Red Cedar with 15% moisture according to Outdoor Living Today, the manufacturer. They say it needs to be stained without any weathering prior to assembling it. The owner said it needs only to be sanded on all surfaces with 100 grit sandpaper prior to any staining. Is your product something that can be applied to new, kiln dried WRC? We are are going to apply the finish in our garage.

Stain both sides of deck boards? I assumed I should stain both sides of my cedar decking board, also the end grain at the cuts. Everything I read here suggests to install the deck, let it weather for a year, then stain. So then I will have to remove the boards to stain all sides and ends? Sounds like a lot of work. But doesn’t the wood need to be sealed all around? Especially the end grain?

I am staining a BBQ bar with TWP 100 (as well as a fence). Because the railings on the top of the bar will see much wear, I want to add a finish coat for additional protection. I know you recommend against this. However, it seems that many boat owners have had success using CPES (Clear Penetrating Epoxy Sealer)after staining but before applying varnish or spar urethane over the CPES wood. Apparently, the CPES does not interfere with the stain (as long as you allow the stain to dry for 2-3 days) and it provides greater longevity to the varnish/urethane.… Read more »

I just stained my decked with 100 series rustic oak. I prepped my deck exactly as directed with restore a deck stripper filled by the brightener. Before I stained it I had touched up a few paint areas on my ceiling of my porch and a couple drops of paint dried on the deck. I just lightly sanded those areas after (after the restore stripper and brightener). As you can see in the photo those areas did not take the stain. Any suggestions?

Just got some TWP 100 stain. Wanted to sand our deck first (8 months old, but lots of rain in WA and some pressure washing to clean the boards raised some of the fibers enough to warrant).

What grit would you recommend? Was going to use 50 grit then maybe 80 – 100 grit to smooth it out some, but if 50 works I’m OK with that.

I am using Restore A Deck Stripper on a $1,150 Sq Ft wraparound deck. The deck has multiple layers of stain that has to be removed. Following the Restore A Deck Stripper directions of 1 cup per gallon and letting it sit for at least 30 minutes requires some aggressive brushing to remove all of the layers of stain. Too loosen the layers of stain more effectively, can I increase the strength of the Restore A Deck Stripper?
