Tips on Applying TWP Semi-Solid Pro-Series
TWP Semi-Solid Stain
TWP Semi-Solid Pro-Series has a coverage rate of 150-300 sq. ft. per gallon, per coat. Best to measure the wood’s square footage to determine how many gallons you’ll need for your project. On wood decks, be sure to include all the railings and steps.
Before applying TWP Semi-Solid Pro-Series Deck Stain be sure the wood surface has been prepped. Use a broom or leaf blower to remove any debris that may have fallen onto the wood since prep.
Applying Semi-Solid Pro-Series Wood Stain
The wood must be dry for a minimum of 48 hours prior to staining and the air temperature should be above 50 degrees. Check your local forecast to make certain there will be several dry days before and after the day you want to stain.
On the day of staining be sure you have all the equipment on site that you will need. Wear protective gloves and safety glasses at all times. Mix the TWP Semi-Solid Pro-Series Wood Stain thoroughly using a paint stick or drill mixer on your drill before and several times during use. Using plastic or tarps to cover any landscaping, siding, windows, or concrete that you don’t want any stain on.
Start with the harder to reach areas first. On wood siding, gazebos, or playsets start up high and work your way down. On a deck, start with the spindles and railings first and stain the deck floor last.
Use a brush, stain pad applicator, or airless sprayer to apply TWP Semi-Solid Pro-Series Deck Stain. The first coat of stain is a saturation coat. If it soaks in quickly within 30 minutes, and the wood seems thirsty, an additional coat may be necessary. If so, apply the second coat within 30 minutes of the first coat, essentially applying them “wet on wet.” Be cautious of over-applying TWP Semi-Solid Pro-Series or performance may be jeopardized. If you notice excessive stain puddles or drips that aren’t being absorbed, use a stain rag or brush to remove them. Stopping in the middle of a piece of wood or board can result in unsightly lap marks. To eliminate the chance of lap marks finish staining each board from end to end once you start.
TWP Semi-Solid Pro-Series has outstanding UV properties and will dive deep into the wood. It is not prone to flaking or peeling like other stains.
I have stripped all the old hated Behr non-penetrating stain from my deck. To make sure I had every bit of it off, I used a belt sander to sand the wood. Do I need to use any kind of cleaner or brightener before applying TWP Semi-solid stain? If I have to use RAD cleaner or brightener, how do I apply it if I do not have a pump sprayer? A TWP tech person I talked to on the phone this morning said after sanding, I would NOT need a cleaner or brightener. I could go right to staining. But online sources say otherwise. I don’t want extra work. Who is correct?
Final prep with teh Gemini Restore Kit: https://www.twpstain.com/gemini-s-restore-a-deck-cleaner-and-brightener-kit
It will open up the pores of the wood so the TWP can soak in better. Apply with a pump sprayer and pressure wash lightly after.
We are applying TWP 1500 semi-transparent over a prior coat of TWP 1500 semi-transparent. Do we have to use stripper to remove all of the prior TWP down to bare wood?
No, but you do have to prep. Use the Gemini Restore kit: https://www.twpstain.com/gemini-s-restore-a-deck-cleaner-and-brightener-kit
Just built new cedar log cabin ready to stain/seal suggestion?

1) When using a sprayer for semi solid pro for first coat will I quickly go back over the sprayed stain with the hard bristle brush sold on your site?
2) Can I use a roller if so what size nap?
3)How many days after prepping do I have to apply stain?
4) Wet on wet second coat must be put on within thirty minutes? How soon after first coat?
5) The Chapin sprayer I received from you has three nozzles. Should I use the fine (red) or the medium (blue) for the cleaner and brighter?
Do we spray a second coat or or no spray just brush (or roll) a second coat.
All of this is on our 3 year old untreated pine deck and pt sides of our dock, using the semi solid pro series in driftwood.
Thanks
1. Yes, you can do this.
2. Rollers dot not a well as the bruh or stain pad.
3. 48 hours.
4. 20-60 minutes after the first coat.
5. yellow
Is there a sample picture of what the semi-solid looks like on wood? Looking to treat my cedar deck but have always used 1500 series. We get heavy afternoon sun. I just want to still be able to see the cedar and not look like a painted deck. Thanks!
Semi-solid colors are more opaque than the TWP 1500 colors. You can test them here:

Under the semi-solid stain details it says 1 coat however in the description of how to apply thr stain it says to use 2 coats. Which is it? Is it like the others with wet on wet and the 2nd application goes twice as far?
It depends on the age of the wood and the porosity of your wood. If older and dried out, then apply two coats wet on wet.
We applied the TWP100 Pecan stain 5 years ago. We expanded the deck in December 2020 and left it to “settle” for 15 months. We now want to stain it using your semi-solid Cedar Mulch stain, so we’ve purchased your stripper/brightener combo to remove the TWP100. I have 2 questions:
1. The daytime temp will be 59° but will drop to 34° in the evening on the day we want to do the stripping/brightening. Is this a problem?
2. How long does the stain need to dry before it would be effected by rain? Would 36 hours be enough?
Thanks for your help!
1. No issues.
2. 12-24 hours.
We cleaned and prepped our 1 year old kiln dried deck per your instructions, and stained with semi-solid yesterday. Despite trying to be sure to even out all our brush strokes, looking back I can now see some places where we overlapped with the brush, especially around the edges of boards, so it has left some boards with darker areas on them. My husband is well aware that he’s supposed to keep a steady hand and stain the whole board at once, and he’s usually pretty good, but this still happened. He’s hoping it’s not quite dry and will not be noticeable in another day or two. My question is is there a way to fix it? It’s just in spots but it bugs me.
Sorry but no, there is not a way to spot fix overlap lines. It may just even out in a week or two.
Have a deck stained about three years ago with twp 100 series in cape cod gray. Would like to restain but with the twp semi solid pro series as I would prefer one of the darker gray shades available in that series. Do I need to strip or will cleaning and brightening suffice for prep?
Use the Restore A Deck Stripper and Brightener Kit to remove the Cape Cod first.
What do you recommend I use on Adirondack chairs made with Beettle-Killed pine: TWP 100, TWP 1500, or TWP Semi-solid? Can all of them be used on outdoor furniture? Which will last longer?
Thank you!
All can be used and they all work the same and last about the same.
I really want to clarify if wet on wet means that the second coat goes directly after how long. I am going to stain a disassembled deck prepped(planed with an electric planer cleaned and brightener) so after I will stain once all the pieces I have to stain them with the second coat immediately?

Does semi-solid stain need to be wiped down with a rag after application?
No.
I’m doing first ever stain for my brand new redwood deck, installed 8 months ago. We’re following the guide posted in the site (one coat only). If we use pressure washer to prep, is there a recommended psi to use? How long do we leave the coat on for drying before we can move back in furnitures, plant pots etc, and walk around it?
See here about new wood: https://twpstainhelp.com/prepping-new-wood-for-twp-stains/
PSI can be around 1500-2000. Let dry for 24-48 hours.
Is there a printed version of the color chart for the solids product?
YOu can print this pdf: https://www.twpstain.com/pdf/TWP%20Semi-Solid%20Wood%20Stain%20Color%20Chart.pdf
So the ProSeries is a version of 100,200, and 1500? I am looking to repaint my house in semi-solid oil based stain. Previous was Cabot but looking like lots of negative changes since 2004 to that product per VOC specs and sale to Valspar. Your products seem to get high marks so very interested. A bit confusing about whether allowed in MA. Also, are there color swatches as it says somewhere no wet samples available. Thanks Beth
The TWP semi solid is not allowed in MA. Only the 1500 Series and you will need to fully remove the Cabot first.
