Need Some Help With TWP Stains?

by TWP Help

Last Updated on January 30, 2023 by TWP Help

We are here to help you with your TWP exterior deck or wood restoration project for 2024!

TWP is an advanced wood preservative/protectant registered by the EPA. Performance and longevity can vary though depending on the wood type, how the wood is prepped, the age of wood, and how the TWP is applied. We want everyone who has decided to use TWP 100, 1500, or 200 Series to have the best possible results.

TWP Stain Tips and Help

When asking questions please give us some information about your wood restoration project:

  • What structure is your wood? Examples would be: Deck, Wood Siding, Fence, etc
  • What species is the wood? Examples: Treated Pine, Cedar, Redwood, Ipe, etc
  • Is the wood new or older than 1 year?
  • Has the wood been stained previously with a different brand? Please specify brand name and type of stain used: Examples: Solid stain, Semi-Transparent Stain, etc.
  • Any additional info that would be useful

Once you supply us with the information, we will able to give you advice as to how to prep your wood and any needed instructions for the TWP application.

Please ask your questions in the comment area.

Thanks

Have a pressure treated pine wood trellace with a currently trimmed back dormant Wysteria. Beleive only treated with oil based russet semi-solid brown over 5 years ago. Local paint places only have latex. This is above a white cement deck. Trellace is about + 20 years old and many cracks and splits especially the top end inch of 2X8s. Would like to go to blue-gray, house is white with slate blue accents and roof. Would TWP 200 be better? Live in PA. Have added new pressure treated pine gate to trellace post with blue water based paint that is fading off after 1 year, plan to strip and paint gate with same sealer after trellace is done hopefully before Wysteria sprouts.

I’m wanting to get an idea of the color that the Cedar would look like on new, treated, kiln dried pine. I’ve seen where you have said it looks different on different woods and time, and application can change things. I get that. But I also get that I’m not about to plop down a couple hundred bucks not having a clue of the final color. I live in E TN. Maybe a store near here has some samples? Maybe there’s a picture online that indicates roughly what it looks like? I”m not saying the picture would be true to color or that it means my deck will look the exact same, but as I said, I’m currently clueless on what it’ll look like colorwise. I need some help.
Thanks

Last spring I cleaned and stained the new cedar deck with TWP 1500. The deck was unstained for a year before.
Some areas are showing white/gray patches, that look like weathered cedar. Most of the deck looks fine. Should I clean and brighten those areas or am I missing something?

I recently stained three ceder beams with TWP 100. It seems like a great stain but I am not crazy about the contrast of my bricks to the color of stain I chose -Rustic Oak. Is it possible to sand off the Rustic Oak and re-apply the Cap Cod Gray?

We are building an oak log home and trying to decide on a stain color. Do you have any photos of 1516 rustic or 1501 cedartone on oak logs? We have samples of both stains, which is really helpful, but would like to see the colors on a full-size home and not just a sample size log.

I need to do some touch up from a deck I stained. Some areas have held up well, and some have faded slightly. Can I reapply 101 cedartone over top of previous coats. I plan on washing and drying the deck first, am I missing any other steps to freshen up the stain I have on there now.

Hello, I applied one coat of cedartone 1500 to a new cedar deck that was bare 6 months to dry last spring. The deck is in a coastal area under a tree. The finish is very uneven and there was some green mold under the chairs and scratches in heavy traffic areas. Could I clean with Gemini cleaner and use two coats of stain to resolve these issues?

I have been recommended to use TWP 1500 on two new garage doors. The doors have exteriors of western red cedar The wood was very dry and the stain job looks good and the stain has taken well. Now I want to seal the doors against the elements with a polyurethane or other oil based sealer with high UV protection. What do you recommend?

Hello, I stained my deck in rustic about 8 months ago and i recently noticed a burn mark on one of the boards. I sanded it out but when i tried to restain the board the stain would not take on parts of the grain. Is there something i should have done differently?

We want to re-apply TWP 100. Live in northern NC. Our pine deck is almost 4 years old. The first coat was TWP 100 cedar tone stain on new pine deck at 18 months old. We used Gemini restore kit and applied wet on wet. It is now almost 4 years old, has some lighter spots and some light green mold in places. Do we use the Gemini Restore kit again? Will pressure washing be OK along with the kit or will it do to much damage? Also how long to dry before applying TWP and can we use just a clear so it will not darken or should we use cedar tone again to apply wet on wet method?

I have a 2 year old tiger wood deck. It has had 3 applications of Penofin Brazilian Rosewood Oil, transparent natural tone. It looks fantastic for awhile after the application, but soon loses its luster. I want to switch to a TWP product. I will prep with a stain stripper and brightener. Will you please recommend a TWP product and color. Thanks.

I have a new home with rough cut board and batten siding. I live in South Dakota and plan to stain this summer. Should I order the 100 or 1500?

I will be installing approx. 350 sq. ft. of tongue and groove Douglas fir vertical grain porch decking soon. The floor is covered by a roof, but open at 3 sides. The location is central North Carolina. The wood is newly milled, and I intend to use TWP100. I planned to pre-treat all sides of the wood prior to installation, but your website is leading me to believe I should install it and then wait before applying your stain. I really do not want to pass up the opportunity to coat all sides of the boards. Can I prepare the surface in some way that would accept the stain better? On a related note, I have heard some talk about a two minute bath in hot water and borate solution, then letting it dry for 2 weeks prior to applying any stain. Would you recommend or suggest against this for your product?
Thanks for your time

We have some new rough cedar underneath our deck and a couple of post caps we’d like to get stained this fall. We’re using TWP 100 series cedar tone stain. We live in MN. What is the minimum temperature for applying TWP 100?

I am in the process of sanding my spruce log home down to bare wood. There are some places in the butt and pass corners that I can not get a sander to, Is it ok to blast these spots with soda or should I blasts with walnut media. If so what grit should I use. I have bought 100 series stain. After sanding is there any other prep that should be done? After sanding do I needs to wait for the logs to weather before staining. I am in Arkansas and we are coming into the wet season. Do I need a moisture tester. If so which one do your recommend? What is the highest percent of moisture that is acceptable? Thank you so much for your help

Western N.C. at 3620 elevation. 15 year old deck so sanded everything with 40 grit and then with 100 grit to remove all old stain. Washed with a cleaner brightener and let dry. Applied Dark oak 2 coats wet on wet before the sun was on the deck. It appears to be drying with a slight “haze” dull gray but it has only been 4 hours. Is this normal? Will the haze go away once it is fully dry?

I have been a TWP user for 27 years. Presently replacing a red cedar deck with Alaskan Yellow Cedar. This cedar has a much tighter grain. As I have success with TWP 100, I would like to continue to use the product. Any recommendations on applying to Alaskan Yellow Cedar – wait times after installation and absorption.

Hi all , my new 5/4 x6 pt decking has bin drying 4 months , just cleaned with Gemini deck restorer and after two days drying I notice little uneven fussy spots in the wood . I took my time with the power washer not to leave marks . Will this fussy marks come out when I stain ? I’m using 1500 honey tone stain? Thanks for your time, jeff

Help! Just stripped my deck with your stripper. (Works great!). However, on the face boards (which had been pre-wet), there are now lots of stain ‘runs’ from cleaning the deck boards. I sprayed some stripper on and scrub it in a bit. Waited 30 mins and powerwashed off. But the runs are still there! How do I get these off???

I stained treated pine deck boards that were replaced and the color is not the same. It as ones that were stained with 1520. The new stain appears to be more transparent and a different color than the previously stained boards although it is the same color stain. Can it be re-coated to get a deeper color and if so how long should I wait. this has only been three days.

What product would be best suited for outdoor seating at our sailing Club in Alabama…constructed 10 years ago of pressure treated pine? Last stained about 5-6 years ago, probably with solvent based stain, but there is no evidence of any of the stain still remaining. Wood is obviously well weathered.. We plan to sand it to remove splinters and rough areas. Portions are under roof, others exposed…East facing exposure.

Hi, I’m removing Behr Waterproofing Wood Finish Penetrating Oil Formula from a large deck (about 1450-1500 sq ft using the calculator) and refinishing with TWP 100. The deck is partially covered by a roof, so the Behr has faded and worn very unevenly; the deck is also long overdue for this. 1500 sq ft puts me right on the line between needing 2 or 3 jars of the RAD Stripper. Can you tell me if the Behr might require more or less stripper? I’m leaning toward ordering 3 jars of the RAD Stripper and 2 jars of the RAD brightener. Thank you!

Two years ago our new deck was stained with TWP1501Cedar Tone and last year it was stained again.Then it got very dirty or coated in darkness over the rainy Seattle winter, so I hired someone to clean it with Restore-A-Deck Steps 1 and 2. Now much of the stain has been stripped off, leaving it all blotchy with stain remaining in patches but not in others. Ideas on 1) why this happened and 2) what to do now? (I didn’t monitor exactly how he was going about using the products, so I don’t have the details about that. I know he was using the pressure washer. Maybe too much pressure?) Thanks

I stained my deck with TWP 1500 3 days ago, using the wet on wet application approach. (Looks great! Love the color!) Weather has been warm and dry since which has allowed the deck to dry well. Some boards still seem “thirsty” – like they didn’t receive as heavy of a coat of stain and are just slightly lighter color. Is it possible to add another light coat of stain to those areas this long after the original application or do you have any other recommendations? Thanks for your help!

I have a 0ne year old 6ft. rough sawn eastern red cedar fence approx 216 linear ft. Sept. 2015 installed. I applied one coat of 101 cedar tone after the install – September that first year. Looks beautiful. Today, I have hosed and wash-scrubbed off any dirt on it. After letting dry for 48 hours, am I okay to apply another coat of the 101 cedar tone? Also, which do you feel will give me a better finished result a pump sprayer w/ back brushing if needed or an airless Graco magnum, project plus sprayer. Not sure if the 101 stain meets the Gracos flashpoint – can’t have flashpoint lower than 100 degrees F. Thanks Lisa

Hello, Please advise! I have a 4 year old pine deck, already showing signs of cracking, nail pops, warping. Never been sealed or stained. Just recently, had it professionally power washed, and I’m pretty sure bleach was the main chemical. It looks fine except for an extreeme case of the fuzzies.

Now, I want to proceed with protecting it. I am at the beach on the Outer Banks of NC.

Mostly full sun except for under stair switch backs which tend to collect green in the shaded parts. I prefer to go with the 100 series I think, honey. There is a section of walkway, however, that is basically on the ground., and this concerns me as for dampness, etc, as it really tends to mold up and get slick.

So — what is my next step? Do I sand, then brighten, then stain? And for the damp walkway, what are my options? Any way to add grit or non-skid? Also, 2 coats — no way with all the pickets and switch backs can I cover the whole thing and do the second coat within 30 minutes! Ha ha! So — can I work on it over the course of say 4 days? Half of it one day, half the next, second coat the same… (Doing it myself, brushing).

I want to do this right, so any advise would be most appreciated! Thank you

I will be using the TWP 100 on a two year old deck that has never been treated, stained.
1. Should I apply only one coat on the verticals?
2. Can I spray verticals or do you recommend a stain pad?
3. Do I need wet on wet second application for the horizontal if this is the first time it has been stained ( even though it has sat for 2 years? )
4. Can I spray the horizontal or do you recommend pad application, which is best?
5. We have peach Victorian with white and dark brown trim. Deck is added to back of house with Victorian features. Would you have a color recommendation. We thought the grey or dark brown.

I have an older deck, 10+ years, that half is in the sun and half covered. I used a very good deck cleaner/prep and pressure washed thoroughly. After completely dry, I began applying TWP1500. The half in the sun has dried beautifully but the half that is covered is still shiny and sticky after one week. I have never treated the deck with anything but suspect that it has been in prior years. I did the water bead test prior to restaining and there was no indication of that anywhere.
Is there anything I can do to force the half to dry or what would you suggest?

We redid the flooring of our decks 2 years ago, stained with TWP Cedartone 101, it’s held up well in the wet shady PNW weather. Some wearing away in more exposed areas where the rain hits it all winter. Just had to replace all the posts and handrails last month, and had to cut out and replace some of the flooring to access. Would like to stain everything again to even it all out. Can I just clean and stain the flooring part to match? What do I do on the older exposed stained areas? Would like to avoid stripping. Perhaps sanding the overlapping areas of new and old wood? For cleaning, is OxyClean ok, or Dawn better?

We have about 1600 sq.ft. of wood deck and stairs with rails and spindles on two buildings in the woods of SE Ohio. They are solid and in pretty good shape, but grayed and aging. What stain and prep do you suggest? Can we retreat without doing all the prep in the future – and if so how often?

Fall of 2014 we restored our cedar deck as per your recommendations. (Restore a deck stripper, brightener and applied TWP 1500 stain.) Due to weather restraints, we didn’t apply a second coat to floor decking. You advised at the time to lightly prep with soapy water in spring and apply light coat of stain. We failed to apply stain in the spring. Here we are one year later. What are your recommendations for prep to apply the second coat for flooring only? FYI – the deck looks good and still “beads-up” when wet.
Thanks.

I am trying to choose between the TWP 100 Honeytone and the TWP 1500 for my beach deck for application on 2-year old pressure-treated wood. My state does not have the VOC regulations, so I have a choice. Which one would be better to stand up to salt and sand and winds?

I have a three tiered deck. The main tier needed to be removed and rebuilt (redwood) due to severe storm damage and was done so last week. It sounds like we should wait until later next summer to clean and prep that portion for TWP 1500 (8-12-months). If we sand, clean and prep the other two levels (redwood) we should be able to stain those earlier next year but still might have some color disparity because of the age of the wood on the tiers….correct?

I am concerned about how my deck will withstand wear after using your cleaner and stain. Prior to that I prepped it including cleaning it using your deck restore kit. When I cleaned the deck a lot of grain came to the surface so I sanded all the decking. It was thoroughly prepped. I have almost completed staining the deck flooring (rails are painted) and have followed all instructions to the letter. I’ve noticed the flooring seems to get scuff or scrape marks on it including where the decking was stained several days ago. Is this normal? Is there a way to prevent it, maybe by putting some type of finishing coat on it? My deck is huge, it’s taken me two months to reach this point of near-completion, so I’d hate to be in a situation of being unhappy with the finished product. Any suggestions?

hi there,

I just applied on my deck TWP 1500 a few days ago.Due to inadequate stain, some area only received one coat. Is it OK to apply another coat one week later on these areas? I know TWP suggests wet on wet.

I am about to put up a new cedar fence. All the wood except the posts will be rough cut cedar. Posts will be treated 4×4. Can I stain right away or do I need to let it weather? I’ve read that if it’s rough cut then I can apply TWP right away. I can use rough cut 4×4 if I have to. The problem is my HOA isn’t going to let me wait that long to stain. I have about 250 ft of fence right along the main road in our neighborhood.

I am building a pergola with Western Red Cedar. The large timbers came rough sawn but all of the dimensional lumber came planed on one side only. I was under the understanding the order was supposed to be ALL rough sawn.

If I get stuck with this, what can I do to make it look good? Can I put a darker stain on the dimensional lumber to match a lighter stain on the timbers? For example, in the 1500 series – Pecan 1520 on the rough sawn and Dark Oak 1503 on the smooth lumber?

Can I rough up the smooth side with 60 grit sandpaper to make it darker.

I am going to the lumber yard tomorrow and any talking points you can provide would be much appreciated. I am in New Mexico, so if you’re in the East, you’re 2 hours ahead.

Thanks!

I have a cedar fence with PT posts. It was installed in May/June 2015. Never stained or sealed. Its just been drying since I installed it. I will want to spray it. It is 244 linear feet long and about 7′ high. One gate.

I want good UV protection but I still want to see some grain. I think that means I would want semi-trans.

Do I want use TWP 100 or 1500? What is the difference?
How many gallons to I need?
What kind of a sprayer do you recommend to apply this?

I attached a few pictures.

I stained my new pressure treated pine deck earlier this year with 100 series Dark Oak. Overall, I am happy with it and it has good color retention, except for the horizontal deck boards. We had a hot summer and it got a fair amount of full sun exposure and now the many of the boards are pretty faded. Additionally, on some boards that are slightly concave where water collects mildew is starting growing (despite being in full sun…)

So, I want to try it with TWP 1500 for the higher solids and mildew resistance.

a) Does the 1500 series film form?

b) If i use the the standard gemini cleaner and brightener will I have any issues applying 1500 over 100?

c) by using the cleaner, will I still retain some of the 100 series stain?

d) to best match 100 dark oak, should I go with 1500 dark oak or black walnut?

e) with the 1500, should expect better mildew and sun irradiation protection?

thanks!

Can we apply several different trial colors of TPW 100 series to our horizontal cedar siding and simply strip them off a day or two later? We have already stripped and brightened the existing siding that is 20 years old here in southeast Michigan. Will we be able to completely remove large sample areas of dark oak, honeytone and pecan without leaving any color change to the existing cedar siding? Can we simply reapply the Restore A Deck stripper and brightener to remove the sample areas?

I have a 4 year old pressure treated deck that was stained with TWP 1500 series three years ago. I just cleaned it, power washed it and restained with TWP 1500 series a month ago. I allowed the deck to dry for 2 weeks after power washing and before restaining. The deck dryed for 24 hrs and then it rained heavily for several days. Within two weeks of staining, I noticed black dirt/mold spots all over the horizontal boards. Do you know what is causing this? Also, I am noticing white powdery stains around several knots in the horizontal boards. Thanks for your help!

1 coat twp1500 cedar

Hi, we just finished 3 days ago one deck of two with twp1500 cedar tone. It turned out to orange/red than what we had in mind. After this experience we are looking more for a cold brown tone, preferably without orange or red undertones. Which of the available colors would come closest to a cold brown.

And is it possible to prepare the deck again for a new coat and color twp1500 after just applying one coat 3 days ago? What needs to be done?

Thank you very much for your advise.

I rebuilt my deck a year ago and used the 1500 stain over cedar without removing the glaze first. The stain dried but did not penetrate well. After a year it is worn off in quite a few places and I am thinking of going over the deck with an orbital sander (80 grit) to remove the glaze and remaining stain. It appears as if the dirt and stain have not penetrated so a light sanding might be enough to prep it for a coat that will penetrate. What do you think of this approach?

Hi. We have a deck that was stained (with an unknown product, not the original buyers) that was previously stained (at least once since 1999) and we are looking to restain. We pressure washed with a very strong pressure washer and the wood now looks bright (pressure treated pine). Researching online, I’m not sure if TWP 1500 will work for my restrain project (we are in MA, can’t get TWP 101). I’m concerned that the deck will not hold the stain. There are some remnants of the previous stain left behind from the previous pressure washing, but not very much. Can you please advise?

Can I use TWP 1502-Redwood over wood previously treated in 2006 with Pittsburgh Paints “Sun Proof” Fence & Siding Stain Alkyd/Oil Semi-Transparent stain (Redwood tint)? I sanded the damaged sun exposed surfaces (not to bare wood) and washed the smooth undamaged surfaces. I would like to apply the TWP 1502 over the existing Pittsburgh stain and do not want to remove the old finish to bare wood. In the past I was able to reapply the Pittsburgh stain over the existing old coat without any problem but Pittsburgh no longer makes this product. I’m painting a house that has smooth finished redwood siding.
