Update on Best Application tips for applying the TWP 1500 Series

TWP 1500 Stain

TWP 1500 Stain

First, measure your wood surface to determine the square footage. TWP 1500 Series Wood and Deck Preservative covers approximately 150-300 sq. ft. per gallon. Buy a little more stain than you need just to be sure you do not run out at the end of the project.

Prior to using TWP 1500 Wood and Deck Stain, clean the wood using a brush or pressure washer along with a quality wood cleaner. Preparing the wood properly will ensure your new TWP Wood Stain will perform optimally.

Once the wood surface is cleaned it must dry for a minimum of 48 hours before any stain can be applied. Be sure the temperature is at least 50 degrees and that dry weather is forecasted for the next several days.
Remove any leaves or debris that may have collected while the wood was drying. Wear protective gear like rubber gloves and safety glasses while completing your wood staining project. Thoroughly mix the TWP 1500 Wood Preservative using a paint stick until it is well blended. Be sure there are no clumps at the bottom of the pail. If the TWP stain has been sitting for some time, a paint store can shake it up for you.

Use plastic to protect any windows, landscaping, concrete, or siding that you do not want to stain. Begin staining the higher areas first. On wood siding, gazebos, wood shakes, and playsets start at the top and stain your way down. On wood decks, it is best to start with the railings and save the deck floor for last.

TWP 1500 Series can be applied in several ways. Use a brush, stain pad, or pump sprayer to apply. With TWP 1500, the first coat is a saturation coat. It should soak in fairly quickly with the exception of new wood which may take longer. If the wood absorbs the first coat with no problem, a second coat of TWP 1500 Stain may be applied. The more stain that is absorbed the better. Apply a second “wet on wet” coat within 30 minutes of the first coat.

Be wary of over-application of the stain. If you see puddles or drips of excess stain that isn’t absorbing into the wood, wipe them away using a brush or stain rag. Do not stop staining in the middle of a board. Doing so can leave lap marks. Finish each board from end to end once you begin staining.

TWP 1500 Series Wood and Deck Preservative is the only wood preservative registered by the EPA. It is designed for all exterior wood surfaces. It has outstanding penetration properties and excellent UV resistance from wood graying. It has superb color retention and is not prone to cracking, peeling, or flaking. TWP 1500 Series will only fade in time and can simply be cleaned and reapplied as necessary for maintenance.

Used your cleaner on this 24 yr old deck this last week. Didnt get a chance to use the brightener because of Ohio weather. The deck looks much better, but I notice it looks a bit orangish? Should I do a re clean and get the brightener on it immediately? Don’t want any mistakes before I stain. Thanks. The deck cleaner is a terrific cleaner. The wood was quite gray.

Have a good weather window for applying TWP 101 later this week; except for unusually cool Florida days. Forecast is for highs around 60 but lows down to about 41. Is this okay if I apply late morning/early afternoon? Shouldn’t drop below 50 until after sundown. Or should I hold off for warmer temps?

Thanks for this excellent forum, btw.

I’ve gotten about 97% of restoleum restore deck cover off my deck. (product is a disgrace!!!!) pro blem is if I try to get the little remaining paint I end up having to sand the whole board to blend it in but now I’m creating new looking boards that don’t match the old boards !! Will the stain blend the boards in or is going to look funny? Or is there any tricks to solve this problem? it’s only about 9 boards out of the whole deck. I was thinking about staining the 9 boards first with ( 2 coats) any letting them dry for a couple of hours an then doing the whole deck including those boards. Do u think that might get them to blend in better. Open for any suggestions. And going forward with finishing the sanding of the deck maybe I should not try to feather in the little spot I just made when I got another little piece of paint up an just leave the spot ? Because now that I’ve removed the spot or ghost of the spot the stain will b able to soak into that spot now an not just rest on top. I got some samples of the rustic 1516 TWP 1500 that we’er going to use this weekend and if u leave any paint or ghost of the paint the paint shows through. Help! Thanks Joe

I use restore kit and stained this deck with TWP 1500 in the spring and it looked very nice. I am now seeing some white spots appearing (see picture). What is this and how can I get rid of it?

Would like to apply tomorrow a.m. to a prepped, mostly covered farmer’s porch, but see a 30% chance of late day showers. The area is small, so if a shower blows through I can lightly cover with a plastic tarp, wondering if I should hold off or stain, what do you recommend?

I’m in central SC and have been pleased with the 100 series cedar product that I manually rolled on a wood dock in full sun a few years ago. This year I plan to apply the 1500 series for better UV protection. I have a Graco sprayer (with .015″ tip) and am considering a pressure roller attachment. Thoughts? Do I need a smaller tip for spraying? Is the stain too thin for a power roller?

In applying TWP1500 you say “be sure the temperature is at least 50 degrees”. If temperature is forecasted to be 60+ during the day but 40 to 50 at night will that be a problem?

Earlier this year, I stripped Olympic Maximum clear sealant from my 7 year-old pressure treated deck and washed the deck with a quality cleaner and brightener in preparation for staining. Since I didn’t stain my deck 4-5 months ago as planned, I’d like to clean and brighten it again before applying your 1500 series stain. Is this plan okay or should I use a bleach and water solution instead as indicated in the 1500 stain preparation instructions for older decks?

Hello, I applied TWP 1500 Series Dark Oak to my cedar deck 7 years back. The color today is still decent looking and the wood hasn’t faded…..very impressed. But, I would like to reapply this stain to make it look awesome again. What is the best way to prep this already stained wood. is a light pressure wash good (since there isn’t a whole lot of sun damage nor is it super dirty), let it dry and then apply 2 coats wet-on-wet? Or does the wood require a deep pressure wash to take off the entire coat of old stain? Please advise. Thank you very much.

On my timber framed porch, I have rough-sawn columns, beams and railings. They are 6 years old, previously finished when it was built with a non-TWP semi-transparent penetrating oil stain. The areas that get the most exposure to the weather/sun/snow/rain have weathered, turning darker/gray. Any suggestions for how to proceed with re-staining them? Prep? Thanks!

I’ve attached pics in .png format-they are a few years old, so the weathering/graying of the wood has gotten worse. Any suggestions for color? I don’t want to match the ceiling or door, prefer something darker/more brown and not orange, yet complementary to the door. Thanks for your help!

I have a Cedar deck that has been stained with Another stain company (Ready Seal). It has been stained 2 years ago. I’m looking for another brand as I’m not satisfied with that product. I’m looking to switch for TWP 1500 pecan. I live in canada.

Now for the prep work, I was thinking of using a cleaner, grinding the deck and applying the TWP stain after. Is grinding the wood necessary? Maybe a stain stripper is enough to remove the old stain? Thanks

Hi
I have been using TWP stain for many years and have been very happy with the product.
2 years ago I clean the deck and re-stained with the 1516 Rustic. In some spots, (deck floor) the stain took forever to completely dry and other area dark spots appeared.
So this year I want to stain the deck but I do not want to have the same problems I did last time, any suggestions on cleaning, preparing and staining it this time.
Thank you

The instructions after prepping day to wait 48 hours for the wood to dry. It has rained every other day since the prepping process was completed. So each time it rains do we wait 48 hours? Until we can stain? Thanks!

Is it safe to apply TWP 1500 to the exterior of a raised vegetable garden bed? This bed is constructed with 6″x6″ cedar posts. I plan to use another type of sealer on the interior, so the TWP will not be in contact with the planting soil.

Now that my wood porch has been stained with twp 1500 (dark oak), do you recommend anything to coat it to make it shinier (eg. satin finish) without using urethane? What about linseed oil? If I use linseed oil, does that cause a problem with re-applying TWP 1500 in a couple of years? Thanks!

I was going to caulk the board & batten siding of our house with a paintable caulk (Sashco’s Lexal) – after the proper surface prep – and then apply your 1500 stain. However, Sashco stated that they have had marginal results using their caulking with TWP stains – so they didn’t recommend their caulk. I have also read that caulking should fully cure for two weeks prior to applying stain.

1.) Can you recommend a brand of caulk that is compatible with your 1500 stain ?
2.) Can one apply your stain first & then caulk later, or must the caulk be applied first ?

Please advise.

Thank you !

I just bought the RAD kit and 1504 Black Walnut, can’t wait to refresh and protect my deck, just looking for a stretch of dry days. However, I just remembered that here in NC, The Great Pollening is now upon us. If I wait the required 48 hours between cleaning the wood and staining, it’ll be covered in yellow pollen. Can I just sweep it off, stain, and hope it dries fast enough before more pollen settles in (possibly a vain hope)? Or should I just wait until pollen season is over, but temps are higher?

2 questions: I have been tasked with using your 1500 series stain to a new fence made of 100% clear s4s cedar.
1) the wood was dried in storage, is there any reason I can’t stain it right away, using proper techniques?
2) the application instructions do not list my usual fence staining application method of an airless sprayer, only pad brush or pump sprayer.
Is that not recommended? Any reasons why I can’t or should not use my usual airless sprayer to apply the 1500 series stain to a new fence?
Thank you!

We have a small pressure treated deck that has TWP 1500 on it. Several boards that have water that stands on them after a rain have turned black. We plan to remove the boards and re-plane them to fresh wood. Then restain them but I want to avoid them turning black over the next year again. Any ideas on why this happens?

I have moved recently to a 30 year old house in the woods in Vermont with a 2 story pine staircase that has never had any finish on it. I would like to clean, stain, preserve it but see that TWP is for exterior use. Do you make any products that can be used on an interior surface? I have used TWP on 2 outdoor decks/staircases. The house is rustic and the stairs are heavily used in all seasons.
