How To Apply TWP 1500 Stain in 2022

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.

I hired a contractor who applied the 1530 natural last year to half of my log home, in 30 degrees Temps while snowing. he pressure washed the logs but did not use a log wash or brightner. he has disappeared and now all the unstained logs are gray, the stain is obviously very splotchy etc. what do I do? strip it all and start over?

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

I just put on 2 gallons of stain on my deck and ran out. Bought it from Ace but can’t get another can until Wed. No one else sells it around me. Will that be ok? It sure looks spotty now. Can I apply a second coat when I get some in?

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.

I will be using TWP 1500 on new rough sawn cedar, 8-10 months after installation. Some boards are slightly graying, do I need to do any prep first?

Riccardo

Does TWP 1500 clear have limited shelf life? I think I remember the site that recommended the product suggested a year, even unopened. If that is correct, I will have to be careful to only order barely enough, and then possibly have to keep adding an order gallon by gallon until finished (inconvenient). On the other hand, if it is good for many years, I will order extra and use the rest in a few years when it is needed again. Is there something special about this product that makes it more/less stable? My garage storage is 50–80 degrees F. (sorry, looked at hundreds of questions and didn’t find this one yet.)

I have some 1500 Pecan to put on our 15-year-old deck that I’ve stripped and prepped with the Gemini kit. It’s mid-October in central Indiana and the daytime highs are between the upper 50s and the mid-70s.
1) Is 48 hours after rain enough time to wait to apply the stain with the wet-on-wet application, or with temps that low do I need more time?
2) Similarly, given those temps, how long would the dry weather have to remain after we apply the stain?
3) If, after the first application dries, I think we need another coat, I’m wondering if we should wait for drier weather. Would you recommend waiting to next summer when there is better weather, or would you recommend trying to get in a later 2nd application before the harsh winter? If you recommend getting that coat in soon, are the recommendations for 48 hours of dry weather before and after the same as they are for unstained wood?

Thanks!

i applied a second coat of TWP Pecan 1500 on my deck a week later after the first coat, it appears to be tacky after 24 hours will it dry or do I need to wipe off the tacky areas with a piece of carpet soaked in paint thinner? we are expecting rain later tonight will that hurt the stain while still tacky?
what do you recommend?
thanks

I will be applying 1500 series Natural on a 12’x20′ cedar deck and railings in southwest Washington state. I have used the stripper and will be using the brightener after sanding off fuzzy areas (with 60-80 grit paper!).

The railing is made of 2×4’s with powder coated bollards, so there’s a fair amount of detailing required at the base of the bollards. What application tool do you recommend for these detailed areas? I am planning to use a roller to apply stain on the 6″ deck boards, but am open to recommendations for that application, too. I purchased your crack application tool to coat the vertical surfaces of the deck boards.

Thank you.

Hi, I got the 1500 stain and the cleaner / brightener Kit.
My wood is 8 years old, never been stained before.
1. How long after cleaner / brightener before I can stain?
2. Do I need to do 1 coat or 2. Most say 1 on wood that never been stained, but this is pretty old wood.

Thanks,

Stained an area to test color. Seem to have some places that are not drying like rest of it. It has been about 18 hrs. I assume I applied too thick and not even. Too late to use rag so I am just going to wait unless you have better idea. Old deck , except new patch boards. Yes It was prepared before staining. I just think i applied too much in some area. Hard to tell when you are doing it. I did small area with a brush, but will use pad for rest of deck.

I have an 800 sqft 25-year old redwood deck in CA, last stained 6 years ago with TWP. When I did it last, I over-applied in some areas, took a while to dry. They still look like new shiny wood after 6 years. Other areas are now faded and dry looking but no flaking after 6 years. Time to do it again. I’ve stripped and brightened test areas with RAD in both shiny and dry places to test stain samples from TWP, and I’m now ready to strip/brighten the whole deck and then stain. I’m concerned about even application of stain with no excess on what was shiny while adequate coverage on the dry areas.

1) Should I use a stain pad or brush? Brush implies bending over, not easy on an 80-year old but I haven’t used a stain pad before.

2) I assume I should do 1.5 coats wet on wet? How best to get “thin” coat on second coat? brush or pad?

3) Should I do gaps with brush while doing second coat or after second coat dries?

4) Should 5 gallons of 1500 be enough or should I get an extra gallon or two (or 5?)?

5) Are California mineral spirits substitutes OK for wiping shiny spots?

6) Should I sand surface where there are fuzzies from grain rising after pressure wash? If so, when?

New installation of T&G Cedar Soffit in 2-story commercial building.
1) Thinking of using 1500 in either natural, honeytone, or cedartone. Do these colors have different amounts of pigment/solids that might make one color more durable than another?
2) Ideally would want to stain a few boards at a time (quickly moving down the length of building) so don’t see overlap marks that come from drying in between, but will be working from a scaffolding up high so not practical to move scaffold so much. Should I be able to stain this 3-4′ wide soffit so that overlap marks won’t happen?
3) Any tips on best way to apply when overhead (spray or roll, then immediately brush in)?
4) Cedar (smooth) installed 2 weeks ago. What is the minimal amount of time I need to wait so it’s ready to be stained?
Thank you!
