Best TWP Stain for Pressure Treated Pine Decking and Fences – TWPStainHelp.com Tips

Pressure-treated pine is probably the most commonly used lumber for most exterior wood projects like decks and fences. It is fairly reasonably priced and widely available. The chemical treatment is to deter insects but is not a protective treating against weather. Pressure-treated pine should be sealed or stained for optimal life expectancy.

TWP Stain Pressure Treated Pine

The best TWP Stain for pressure-treated pine is the 100 Series original formula. This is an EPA registered wood preservative that contains 30 – 40% solids to help block out harmful UV rays and moisture. The 100 Series Stain is available in 6 different colors that enhance the natural beauty of the wood while providing excellent protection.

The TWP 100 Series formula is not prone to mold or mildew, which can lead to wood rot and decay. It dives deep into the wood pores and dries within 2-6 hours of application. This user-friendly formula does contain higher levels of VOC and is not available in all states. Check your location’s availability prior to ordering.

The best TWP stain for pressure treated pine where the 100 Series is not available is TWP 1500 Series. This low VOC blend is compliant in all 50 states. Also, an EPA registered wood preservative, TWP 1500 penetrates pressure treated pine for optimal weather shielding and enhanced beauty. It contains its own mildewcides that help eradicate mold and mildew growth.

Either stain, the 100 or 1500 Series is the best TWP stain for pressure treated pine decks, fences, or other exterior surfaces. Depending on the wood’s porosity, TWP can be applied in 1 or 2 coats. If 2 coats are necessary it is best applied “wet on wet” to ensure maximum absorption and an even finish. The TWP stain is easy to apply and maintain. It will ensure your pressure treated pine surfaces hold their beauty and last for many years to come.

I planned and prepped my deck to stain tomorrow, and now we have a heat advisory with high humidity (summers in Illinois), as long as I am applying in temps between 50 and 90, is it okay to continue…it’s been difficult to find a window without rain this spring.

How well do I need you clean my deck if I always use TWP 100?

I have treated pine decking. Installed two years ago. A year after installation and a MI winter I applied deck cleaner for another product and got most of it off but stopped due to illness Some mill glaze (fuzzies) appeared after cleaner. Still there on some planks. Never applied brightner. Two years now uncovered planks.See photos. Some have UV damage. Some green algae on some tops. Ready to use TWP 100 Pro Series or TWP 1500 series. Just want clear finish. Suggestion? Do I need gemini restore a deck, your brightner AND your product to address mill glaze/fuzzies? Or, do I sand lightly with 80 grit paper any mill glaze/fuzzies that may appear after your cleaner and brighter products? Thanks.

Fuzzies (mill glaze) on some planks now. Would brightner also bring out more mill glaze in addition to cleaner, and therefore wait to sand after brightner has dried? Also, I understand TWP 1500 series offers good UV protection, compared to TWP 100 Pro series. If so, what stain color do you recommend in TWP 1500 series to give me as close to a clear look as follows but still the UV protection? Thank you.

So, cleaner, let wood dry, sand, then brightener? How long to let deck dry after applying cleaner and sanding?

Would you recommend the TWP or the GWP 1500 series for my two-year old pine deck that has never been stained but gone through two MI winters? Put one coat on this year or two coats?

Thank you. I’ll be going with either redwood or cedar tone. My deck is 400 square feet. would one 5 gallon can be enough for two coats wet on wet? Also do you have link where I can study up on how to apply the stain? proper use of power washer (nozzels, etc) in using the cleaner and brightener. Thank you very much.

Hi, for this newbie, can you please tell me what this means? Apply first coat, then apply second coat when? 15 minutes after 1st coat? 1 hour after first?

Thanks. Question: I’ve got mill glaze on some boards (see attached photos-deck is two years ago-never stained). Previous answer I got from your company said to sand AFTER the cleaner and BEFORE the brightener. 3 questions: a) What grit sandpaper do you recommend I use to remove the mill glaze on some of the planks? 60-80? Your website says: Do not apply 2 coats of stain to new wood or decking or to recently sanded wood that was sanded finer than 60-80 grit as the TWP stain may not be able to fully absorb into the wood. b) You saying then if I used at least 60-80 grit sand paper on the planks with mill glaze I MAY be able to do a second coat? Just want to know if I will be applying a second coat or not of TWP 100.

Thanks. Final questions, and my apologies as I’m a newbie to deck staining–1) Assuming I will need to let deck dry (a day? several hours) after applying the cleaner so I can sand? 3) How long to let deck dry before applying one coat of the TWP 100? 4) How long to wait before applying a second coat? 1 year? 2 years? And when that time comes do I only need use cleaner before applying second coat? Thanks.

Why only apply one coat after sanding?

OK But remember NOT all of the boards on this two-year old pine treated deck that has sat for two years need to be sanded. Only the ones that have mill glaze on them now.

Lastly, if I apply one coat now here in September, wait until Summer or fall 2022 to apply second coat…do I need to reapply the cleaner…and the the brightener before doing the second coat in 2022?

Thanks. I other words, simply cleaner, brightner apply, O STRIPPING OFF OF THE FIRST COAT?

Considering that we are now talking about December…would the better option be wait until Spring?

I have used the TWP 100 on a cedar pergola and porch ceilings …great. Am considering a 4 board horse fence project and am CONSIDERING TWP clear as a SEALER and water proofing application .. and then will prime and paint with a quality latex white semi gloss paint. Goal is to SEAL the wood, minimize checking / splitting / warping. Will be pre drilling pilot holes in boards .. and not putting screws too close to the edges. Prefer the 1500 for low VOC as the 100 was nasty (for me) to use in an enclosed garage to prep everything prior to install. Will the 1500 serve as a quality sealant? Thanks.

I have a 18×30 Pergola (made with Pressure treated pine). Its approx. 10 year old and never appeared to be stained. My plan is to place a roof over it and stain the wood. I cleaned the wood and its ready to stain. I was looking at the Dark OAK. My question is what type of Stain should I use TWP 100 or 1500. ( I live in near Detroit MI) and why?
TWP 100 seems to penetrate deeper but the 1500 has more Volume solids and coverage per Gallon. Is the 1500 an improved formula over the 100? is the 1500 better for 4 season climates? I saw the comparison review but that didn’t really answer my questions.

Thanks

I moved into a house with a rather large deck. Last owner (just before selling the house) painted it with paint (some HD brand) which was not even meant for deck. It was just exterior wood paint meant for railings. Paint is peeling over all over the place and is an ugly mess.
Deck is made of pressure treated pine and is largely in good shape (15 year old deck). I have already sanding the deck and mid way through. After heavy sanding with 50 grit (belt) sander the wood is coming out nice and clean.

What are the next recommended steps after sanding to stain it with TWP 100. How many coats are recommended

thanks
S
