TWP Stain Tips for New wood Decks in 2024

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.

Tips for TWP and New 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!

TWP Pro 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.

So I planned on staining my 16 month old deck in the next few weeks. I noticed a board or two are warped and need to be replaced. The new boards will be brand new and fully treated. Should I now wait until next year? Stain the others now and not these two? Or go ahead and stain them anyway? Thank you

I have a 3 or 4 year old deck (1360sft including railings, stairs, etc.) that has never been stained. 5/4 PT pine, SYP dimensional.

I will be using TWP 1500, after the Gemini kit.

Should I plan on applying one, or two coats?

The coverage for first coat is 6.8-9 Gal (150-200 sft/gal) and the second coat is 4.5-6.8 Gal (200-300 sft/gal) total for minimum coverage is 15.8Gal – Think I can do (3) 5Gal pails?

Thanks!

Installing a new cedar pergola. I’d like to maintain as much of the cedar color as I can without it greying (hence the reason I’m looking into your products.) I’ve read your prep instructions but just want make sure I understand… So I have to weather my cedar (basically allowing it to grey) before applying your product? Located in WI where it will be exposed to all elements.

I have a 2 story covered PT pine deck that was built last spring, the wood itself probably sat on site since the winter, so almost a full year old at least. I was planning on sanding it with either 80 or 100 grit before cleaning and staining it. Should I still plan on just 1 coat for new wood as mentioned above or should I plan on 2 coats due to sanding it before? I would assume the sanding would make it more absorbent unless I sanded it with too fine of a finish like 120-150 grit. Also I’m in Southwest Missouri. I was planning on using the 1500 series but should I go with the 100 instead? I liked the idea of the 1500 series being UV protectant vs the 100 series not being but I believe somewhere on here it recommended the 100 series for new wood.

We have a pressure treated 2 board ranch style fence. It was installed over 5 years ago & we never got around to staining/sealing. See photo attached. It has now been cleaned & prepped but not sure which TWP product. We are in Georgia. Want what will last the longest & provide best protection. Want color to be close to the color of pinestraw in the photo. The guys who maintain our cedar shake roof use 200 on it. How do we decide which to use, 100, 200 or 1500? Thanks!

SInce the recommendation is one coat only for the 100 series stain, how much stain do I need? I calculate 4 5 gal Gemini cleaner/brightener. Is honeytone or cedartone your most natural looking 100 series?

I am using Cedar Deck Boards from Menards as trim for an outdoor kitchen.

I want to use the TWP100 in cape cod gray to stain new fir plywood that will be the ceiling inside a pavilion, so not directly exposed to the elements. I don’t know if plywood follows the same manufacturing process as solid sawn wood that requires the wood to open for a few months before staining. Can you advise if it can be stained right away or if it needs to weather first like solid wood?

Also, a separate question: If cedar is stored in an outdoor lumberyard (covered) for several months, does that count as the weathering, or does it need to weather on site?

Joel

Reply to  TWP Help

Thanks for the response. It’s rough cut plywood, and so is the cedar framing, so does that mean I can stain right away after prep?

Also, I like a color somewhere between the cedartone and the redwood, like a toned down redwood. Can those two be mixed to a custom color, and do you have any recommendations for that?

Thanks again. Because it doesn’t need to weather, it looks like I don’t need to use the Restore-A Deck first, unless the wood looks aged.

Because it’s a pavilion with exposed rafters and the plywood above the rafters will be stained a different color, it will be quite a job masking it all every time I re-stain it. That’s why I want to stain it for the first time prior to construction. Because it’s rough sawn, can I follow the 2 coat wet on wet application to get the most mileage out of the initial staining, or should I only use one coat? The guide says “One coat for most instances of newly installed Rough Sawn wood”, so does this fall outside of “most instances” or not? Is there anything that can be done to improve absorption the first time? It looks like the 100 will maybe do a better job at penetrating than the 1500, which is why I was leaning that direction. Is that accurate?

I have applied one coat to my new deck last year. The deck looks great except a small area that got sprinkler water every three days.
1, How do I determine when to do the second coat?
1, How long do I wait to apply the stain after cleaning the deck with soap and water?
2, when can the deck take rain after staining
3, do I need to sand the small area that got water sprayed on before staining?

Thanks for your prompt reply! Very helpful.
I live in San Francisco Bay Area. Raining season is Oct to March.
1, Just to confirm, the first coat to the new deck was done in September 2021. Do you advise that I wait till spring 2023?
2, use the Gemini restore kit, no light sanding needed?
3, the area that got water sprayed on is in the attached photo. Should I take care of it this year?

I screwed up and didn’t read this before applying TWP 100 to new deck (kiln dried doug fir.) I could tell right away it didn’t penetrate deeply like it did into older rough sawn wood that we stained. Will this be a problem, or is it more just that it isn’t doing much on top and I will have to reapply sooner (next summer after it weathers over the winter and spring?). Thanks.

What is the reason for this – will the coat sitting on top prevent the second coat from penetrating? Or is this more for an even appearance. Thanks for your help.

Following that rationale, it means that coat does not allow the wood to weather and the next coat to soak in – is that correct?

I am sanding and staining a smooth STK Western Red Cedar for the soffit of our new home. The soffit will never see sunlight so I do not think it will ever properly weather as described in the instructions. Additionally it would be nice to stain this on the ground, before it gets installed, to make life a lot easier. How would you suggest I apply the stain?

Just saw an answer to my question about stain color that would keep cedar porch posts looking like new wood and it seems one that light would not give it much protection from graying? Which would you suggest so that I’m not having to redo them real often, but without them being dark? Typically how often must they be redone and is it a matter of completing the whole cleaning and staining process all over? I believe I read that there is no stripping needed if you used your product previously? Can you pressure wash to freshen them up later without having to redo stain or does that take the color/protection off? Thank you!!

Ready to strip and brighten our deck this weekend. Is it okay to use the same pump sprayer for the stripper+additives, rinse it well, then use it for the brightener? Or should we do the stripper+additives with a car wash brush and then a sprayer just for the brightener? We haven’t bought any application products yet as I wanted to read all of the packaging first and it just arrived today. Thanks for quickly and patiently answering so many questions from so many folks!

How do I know which samples are for the TWP1500 Series. I want a semi-solid stain. I see that there are some same number, such as TWP 15?? but then there are samples listed at the bottom that say TWP??? semi-solid. I don’t know what I should be ordering. I would be helpful if there were individual sample lists for the individual products.

I just ordered four of the TP100 5 gal and restore-a-deck kits to stain about 3500 sqft of boat dock and pier. Constructed of pressure treated pine about 2 years ago in Houston and never been stained/sealed before, so probably 1 coat on the covered vertical areas and wet-on-wet for the exposed horizontals?
Can you please confirm recommended order and timing? Step 1 restore-a-deck cleaner applied with a pump sprayer, Step 2 restore-a-deck brightener applied with a pump sprayer, Step 3 power wash off the brightener, wait 48 hours before Step 4 staining?
Several mentions of waiting a minimum of 48 hours after rinsing the brightener before staining, but I anticipate 2 people will take an entire weekend to prep 3500 sqft with the restore-a-deck (lots of columns, closet, trim, etc.). Is it OK to wait until the next weekend to stain? What is the maximum time allowed between rinsing the brightener and staining?

I am preparing to replace a small section of cedar shingle roof, the area is high on second floor and will be difficult to access after I am finished (I am renting a lift to do this). I want to pre-stain the shingles with twp-200, yet I read here that is not recommended. What will happen if I pre-stain? Once the shingles are applied to the roof, I will only be able to treat the top, I want to preserve the entire shingle. Can anyone tell me what happens if I pre-stain? I really appreciate it, thank you!

New cedar deck finished Jun ‘19…restore a deck clean and bright + 1st light application of TWP100 Pecan in Jun ‘20…clean and bright cleaning and 2nd light application of TWP Pecan in July ‘20…missed some weather/work opportunities this spring’22 but did get in a light pressure wash in June. I have over a half 5g bucket of stain left over from last year and was wanting to apply it this year with a light soapy water and reapply OR I’ll have to bag it until next year with new product. Is it ever ok to apply maintenance coat without cleaning? I’m guessing no 😊. Here in Coeur d’Alene Idaho.

My wife ordered the restore a deck stripper, and thickening gel. We have a 40 year old log cabin and we are restoring it, pressure washing the grey. She is wondering if the product is fine to use on oak logs and if the color will change at all.

2. I’m wondering if I can pressure wash some parts and sand others. I started with pressure washing and it is fuzzing the wood a bit so I thought of switching to sanding. Now I’m waiting for the product to arrive to spray on and then Pressure wash as I imagine it will be easier to wash off old stain and grey once applying the stripping agent. Also the water from washing is soaking our foundation and seeping in through the basement bricks so I didn’t want to keep washing too much. Thanks, newbie here

I have a 2 year old untreated glu lam beam framed porch with tongue and groove ceiling. Wood has grayed, cracked and grain lifted heavily. Small black mold spots. I have already started orbital sanding with 60 grit. Did I mess up by doing this? I see that your description says that twp likes old graying wood. I never would have imagined that. Wouldnt grey wood have a different color outcome?

We are currently building a new residence in southeast Tx. The house has a wrap around porch with 8 x 8 rough and green cypress post, 4 x 6 rough cut pine ceiling joist and 1 x 12 rough cut pine ceiling boards. The mill recommended the TWP stain but told us they treated their cypress while it was still wet. After reading your info and some of the reviews it seems that we need to let the wood weather first. My wife wants to sand some of the rough surface on the post to take off a little of the roughness. Will that effect the staining process in how the cypress takes the stain?

Pressure treated deck finished in Sept, cured 8mo in east TX full sun east side house to Jun. Husband applied cleaner with broom (no sprayer available), rinsed with old power washer (low water pressure here, so he said was below recommended amount), applied brightener and rinsed. When it dried there were white areas on the deck and the wood has 3 dimensional fuzz so it looked & felt rough. He rinsed the whole thing again, but there is still white residue when dry…and the rough fuzz remains.

He stained the sides and one bench top (wet-on-wet 2 coats) before stopping due to the humid heat.

When dry, it looks terrible, as it is uneven where the white splotches were, but even worse is the rough fuzzy wood did not settle down to a smooth surface. We used these same Gemini cleaner & brighteners several times on our wood deck at our previous house and never any issues at all, so he knows how to apply it…only difference was it was new wood and he applied (as directions said was OK) with a broom instead of spraying.

We’d never enjoy the deck floor feeling that rough fuzz, so he agreed to sand it down and start over. He used 80grit got it better, but it still is slightly rough where the fuzz was, so it isn’t smooth as before, or as I’d like to feel. He insists he could just rinse it and finish staining. I say the instructions require re-cleaning (to open the wood pore from sanding) and re-brightening (to stop the chemical reaction of the cleaner).

1) After all this work, is there anything else to do in order to make the stain soak in well? We are using the 100 Series – Honey tone.
2) One coat or 2, wet-on-wet? (The bench top seems to absorb it well)
3) The resistance to re-cleaning/re-brightening isn’t the work, it’s the belief it created the fuzzing and white splotches. How do we keep that from reoccurring?

We’d appreciate your assistance and direction.

Please clarify a bit, on oxidation/graying removal. The 8mo sun dried, pressure-treated wood still looked new with no graying, so are your referring to the bit of yellow-orange color that came off during the power-wash rinse as the cause for raising the rough “fuzz” of the wood?

My husband has a recollection that a 2nd coat might be applied 1-2 month later that would soak in OK and make it last longer. Is that correct?

P.S. Thanks for your quick reply!

After Cleaner and Brightener were used, I applied wet on wet, 3 different sample stains (Rustic, Cal Redwood, Pecan) onto never stained Pressure Treated Pine deck installed 1 year ago – but, all 3 stains looked blotchy. I think that’s because I’m trying to turn PT pine into something it’s not. Could the answer be to use a Semi-Solid stain? Would that be less blotchy over PT pine and have a smoother look? Is there a Semi-Solid photo album showing before and after shots?

  2. Is one coat sufficient?
  3. Am I correct that for new fences, I do not need to wait nor prep before painting?
  4. Is spraying appropriate or not?
