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.

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 did a wet on wet second coat while applying the TWP 1500 stain today, but it looks like maybe I could benefit from a second coat tomorrow after the initial dry. Is this ok to do?

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?

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,
Chris

One more question. Can I use a paint stirrer in my drill to stir this? Or should I just use a paint stick?

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!

Thank you very much. I know I have to stain between the boards and I do it after I apply the stain to the top of the boards. Do I wait until the top is dry and then go back and do between? Or can I walk on it after staining and do the between part?

We are applying TWP 1501 right now on our deck and there is little bubbles in it when applied. We brush over them but they keep coming back. Why are they appearing and what do we do with them? Nina

we have waited 48 hours after cleaning and brightening. We had a small amount of moisture overnight so the surface is damp in spots to the touch. Do we have to wait another 48 hours to dry or when can we apply our 1500 stain?

Hello,

I have a PT pine deck that I’ve always used 1501 Cedartone on, cleaning and brightening before each re-application every 2-3 years. After cleaning and brightening this time around (and this could have been the case last time) there are two spots where the previous coat of stain is still intact, one more than the other. My question is, can I stain the deck wet-on-wet, but use a single coat on these two spots so as to blend them in with the remainder of the deck?

Thank you for the reply. So, I should get satisfactory results staining wet-on-wet in this case?

My contractor recently stained my deck and parts of the floor boards are still tacky and sticky to the touch. They look shiny and wet compared to other boards that look dry and perfect. This will be the third time staining it within the past 6 years. We’ve always used the same stain every time. We also prepped the deck with TWP products this time so I’m not sure what is going on. Finally, its been 72 hours since applying the stain. This happened last time and we left it alone only to find out that the sticky parts got really dirty with passing time. So I’d like to do something about it before it gets dirty again this time.

What can I do to remove the sticky, wet parts of the deck? I’ve read online that mineral spirits may help take up and spread out the extra stain but I figured I’d ask a TWP expert before trying it.

My question regards the “wet on wet” instructions for TWP 1500 stain. You say that the second coat should be applied 30 minutes after the first. Does that mean that it is okay to step or kneel on the area that has gotten the first coat? Or, should I only do as many boards as I can reach without stepping on them to apply the second coat? I’ll be applying the stain using a 6″ stain brush.
