Switching to TWP Stains

Changing to TWP Wood and Deck Stain Tips

Many exterior wood and deck owners have dealt with the task of changing their wood surface’s appearance by simply switching to a different wood stain. Whether you want a different look or you are tired of inferior wood stains that don’t last, switching to TWP stain is a good investment.

TWP is an EPA registered exterior wood preservative. It has excellent UV blocking and color retention properties that make it a superb choice for all exterior wood surfaces.

Before switching to TWP Wood Stains, you first have to remove all remnants of the old failing stain. Use a wood stain stripper and not a wood cleaner. Wood cleaners are not aggressive enough to remove old stains. Applying a wood stain stripper will soften the most transparent, semi-transparent, and semi-solid water and oil-based wood stains.

Apply the wood stain remover using a pump sprayer. Be sure to protect any surrounding shrubbery or landscaping. Once the stain stripper has dwelled on the wood for several minutes, use a stiff brush and garden hose or a pressure washer to lightly wash away the contaminants. For removing stubborn wood stains, several applications and a more aggressive approach may be necessary. Try increasing the strength of the stain stripper and/or the dwell time before washing off.

Once you are certain all the old stain is gone rinse the wood thoroughly then apply a wood brightener to the surface. This is a necessary step after using a caustic stain stripper. A deck brightener will reverse the darkening effect of the stripper and will correct the pH level to a neutral state. This brightening step will allow for better stain penetration and a better overall appearance. After brightening the wood, rinse well.

Allow the wood to dry for 48 hours minimum. If necessary, you can use a sander to remove any small areas of old stain that may still remain. Wipe any sanded areas clean with mineral spirits and allow it to dry before continuing.

Once all the old stain is gone and you have restored the appearance of your exterior wood surface, follow the Stain Application Instructions for TWP Stain.

My contractor is using outdoor Clorox to clean my deck which was previously stained with an oil based stain. He is then going to apply TWP stain. Should he strip & brighten the deck after cleaning with the Clorox? He is telling me this doesn’t need to be done, that the clorox cleaning is all that needs to be done. The Clorox did lighten the previous stain but, I’m not sure it removed it.

Our home owners association specified that we had to use Sherman Williams semi-transparent super deck stain for our decks.
I sanded my entire deck and put down two coats of stain last summer 2019.
It came out o.k. but I want to apply another coat of semi transparent oil stain (of better quality) this summer 2020.

Since my deck is in good shape (no pealing, no mold, no issues with coloration) can I clean my deck and then following TWP procedures re-stain my deck?

Thank you for taking the time to answer my question.

I have a 20+ year old redwood deck that has been coated multiple times over the years (it kept peeling) with the HD Behr transparent stain. I am planning on sanding off the old stain completely and applying a TWP product to deck and railings. What is the best TWP product to use, 100 or 1500, and is more prep needed after sanding? I live at 6000 ft elevation in New Mexico – lots of UV.

I sanded the old product off, cleaned and brightened, got the appropriate dry time in and applied TWP. It looks great. In it’s Pre-TWP life, I washed the deck by hosing down to moisten the dirt, then mopped it with (very) diluted Dawn dish washing liquid and rinsed it off with a hose. I did this about bi-monthly to keep it looking good, as dust, rain, tree droppings, etc. would create a layer of dirt that just wouldn’t come off with just a hose-down. Will this method degrade the product any? Is there a preferable method for routine cleaning that… Read more »

2 Summers ago I built a 950 sq ft KDAT pine 2″x6″ deck with IPE trimmings. The pine was purchased with a rough mill finish. I planed all pine to a very narrow tolerance to match the IPE. Then did 1/4″ round over edges with my router. The boards were then stained with 2 coats, wet on wet TWP 1500 and allowed to dry for 1 month at 60°F+. Decking was installed with a hidden fastener system. The end product was breathtaking. By spring of last year, what appeared to be a black staining was everywhere. The deck was cleaned… Read more »

I have a small 5/4 treated yellow pine deck I built three summers ago. I stained it a couple of months after construction with a water-based Thompsons waterproofing semi-transparent stain & sealer. It peels and needs re-staining each year. Seems it just can’t cope with West Michigan winters, even when I’ve tarpped it. Am I correct in thinking that I’ll have to use something like the Gemini Restore-A-Deck Kit stripper and neutralizing brightener before re-staining (w/ TWP-100)? Should I rent and use a power washer? Would that give me better results? (it’s a small deck, only about 10’x6′). Would it… Read more »

I have home with a large amount of cedar shake siding that is in need of re-staining. I am unsure what product has previously been used. The majority was a transparent oil based(I think) stain. A small area that was redone with a remodel had a semitransparent stain in attempts to match the older darker cedar shakes. It is all fairly dried out.

I have a pine log cabin that we are preparing to refinish. I have used TWP 100 numerous times on decks and have loved it, so I am wanting to use a TWP product (100 or 1500) for the cabin finish. First question, does one finish have distinct advantages over the other? I am in Arkansas so no V.O.C. regs to dictate decision.

Both the TWP 100 and the 1500 last about the same. There is slightly more pigment in the 1500 so it is possible that on log siding you may get a little better UV protection. You should be okay with the prep. Look for chinking products that are compatible with oil based stains. TWP will not “stain” or color chinking or caulking. You cannot make it disappear. If you want it to blend, the chinking/caulking must be similar in color prior to staining.

Last year applied Superdeck oil natural stain preservative to my 6 year old deck that had been stripped, cleaned, and sanded. The product dried patchy with large dark spots over the entire deck. I have cleaned, powerwashed, and brightened it to get it ready for restaining. Some darker patchy areas remain. Water does not bead up currently. Woud like to try TWP.
Would I need to strip deck prior to applying TWP to ensure penetration into the wood?

I have a pine pergola that was stained years ago with the old formulation of Cabot Australian Timber Oil (Jarrah Brown). It has stood up pretty well but now I can’t get the old formulation and I need to start thinking about maintaining the top horizontal surfaces at least. We live in southern NH. What do you recommend from a TWP perspective?

Hi Paul, To be able to use the TWP you will need to remove the old Cabot ATO first. Using the Restore A Deck Stain Stripper and a pressure washer will do this for you. Apply the RAD Wood Brightener when done with the stripping of the Cabot. As for stain, look at the Dark Oak color to be “similar” to the Jarrah Brown.

Hello, you need to remove the SuperDeck from the wood before using TWP. Use the Restore A Deck Stain stripper and pressure washing. Apply the RAD brightener after. Once prepped, let dry for 48 hours before using the TWP. We are a online dealer and can ship all the products to you.

The Stripper does not remove paint fully but it may remove some if the paint is deteriorating. You will must likely need to touch up the paint when done.

My deck has Cabot Australian Timberwood on all the horizontal surfaces and a latex exterior paint on the vertical posts. I’d like to switch to TWP for the deck stain, and understand that I need to apply the RAD stripper followed by a brightener. Will either of these products affect my latex paint? Do I need to use any special precautions to avoid accidentally stripping the paint off along with the old oil stain?

Thanks! A follow-up question: right now our temperatures are in the 70s-80s during the day, and our overnight lows can drop to upper 40s. The instructions say to apply when it’s over 50 F. Is it OK that the overnight lows drop down to 46-47-48 F, though?

We have a few cedar planter boxes that were sealed last year with Thompson’s water sealant (clear). I sanded the surfaces down, and am pretty sure I got it off. What’s my next step? Do I need to use RAD stripper, or is cleaner sufficient? In either case, I’ll of course follow by brightener.

Our painter applied TWP 200 in Butternut brown to our cedar deck last week. We had power washed and sanded the deck prior to application. Sadly the color is very orange looking and still has not dried. What should we do now if it does not dry or I can’t look at the color anymore? Will newly applied stain soften much? Can we apply another color without stripping?

The 200 Series will lighten in color after 2-3 weeks as it continues to soak deep into the wood. I would leave it alone until then. It will dry as well.

Julie, since this was sanded it would be helpful to lightly clean and brighten the wood now. This will help the stain to penetrate. As for stain, apply one coat now and another light maintenance coat (horizontals only) next Spring after a light cleaning/rinsing to remove the dirt and grime.

I am in SE Wisconsin, I have a 15-yr old deck that had previously been stained with Behr semi-solid waterproofing stain. I purchased the RAD Stripper, Cleaner, Brightener, and TWP stain. The Behr stain was practically immune to the stripper, even mixing it at double strength and leaving it on twice as long as recommended. Therefore, we sanded the entire deck to remove the old stain. Since we have now invested 20+ hours in preparing the deck for staining, I want to make sure I do everything right from here on out to ensure the TWP stain goes on properly.… Read more »

I used TWP Cedartone when I first built my deck about 10 yrs. ago and was very satisfied. I refreshed it after 2-3 years and was satisfied again.

I’ve just about got all that stain off and want to change back to TWP. Looking at the specs I see that the 1500 series has more solids and less VOCs than the 100 series. Does that mean that the… Read more »

Ed, you cannot add a coating on top of the TWP. It will not work and create big issues down the road with peeling. Adding more TWP will not work either as TWP is supposed to soak into the wood, not dry on top of the wood creating a film.

I stripped, brightened and stained my deck with TWP and love the way it looks. However, whenever the slightest bit of dirt gets on it, removal is not easy. I first tired hosing and sweeping and another day I mopped but neither removed typical outside dirt. I scrubbed it today, and some came off, but I am not about to scrub my deck weekly! Is there something I can put over the TWP to maybe make it a little glossier to help dirt wash off? Or do you have another idea? Another coat of TWP? Has anyone else had this… Read more »

We had our home painted last month and the painters pressure washed and used linseed oil on a wood pergola on our patio. The pressure washing removed most of the previous dark stain of the wood (not sure what the stain was, we purchased the home a few months ago). Can I use a dark stain TWP100 or TWP1500 over the linseed oil? Are there any other steps to take before I can stain the pergola dark again?

My deck has just been stripped with an unknown stripper — our “guy” was not knowledgeable/willing to discuss a neutralizer/brightener, and I don’t know what he used to strip the deck, but he did power wash it off after 30 mins. working time. He stated the deck would “whiten” as it dries. Can we safely skip the brightener step, especially if satisfied with the appearance of the stripped deck, or does the unknown stripper need to be neutralized with a brightener? Does a brightener enhance the stain absorption so much that is really recommended in this case?

TWPStainHelp

Trex, yes you should brighten to restore the pH balance and neutralize the cleaner. The stain will also perform better.

Hello. If you folks were going to come over and tell me if my deck was ready for TWP 1500, what would you look for? I’ve cleaned, stripped 2x, some areas 3x, and now brightened. I want to make sure I’m giving TWP every benefit of proper prep before I apply it. Can you tell us what to look for in terms of knowing when we are ready for staining. The prior stain was Superdeck Semi Transparent Oil. The deck is cedar. It is about 16 months old.

I stained a new cedar deck and gazebo with Penofin red label cedar tint last year. Today all of the horizontal surfaces are near black and look 20 years old. I plan to get rid of the Penofin crap and use TWP 100. I know stripping is mentioned a lot, but I’m thinking about renting a floor sander and be done with it quicker. Is that acceptable? If so, is a cleaner and brightener still necessary? Thanks.

Thanks for the reply. More questions. Isn’t pressure washing damaging to the wood? If I do that would the procedure be 1. Spray on the stripper, 2. Powerwash, 3. Brighten, 4. Stain? Do I need to scrub between steps 1 and 2? Where does the ‘cleaner’ come in, or does the stripper take its place? Final question: part of my cedar deck has never been stained, but is weathered. Would just a cleaner/brightener be sufficient? Thanks again.
