Best Way to Apply TWP 100 and 1500 Series Wood Decking Stains

It is best to first measure the wood surface of your staining project. Do not forget to include steps, railings and spindles if you are staining a deck and double the footage of a fence if staining both sides. On average TWP covers approximately 150-300 sq. ft. per gallon. The newer the wood the less stain it will take. Older wood is more porous and will absorb more stain.

Prior to applying any TWP stain be sure the surface is free of dirt, grime, mildew or any old coatings. Use a wood cleaner when no old failed coatings are present. If an old coating is to be removed use a wood stain stripper instead. Allow the wood to dry for 48 hours after cleaning.

The best way to apply TWP is with a brush, roller, stain pad, pump or airless sprayer. Be sure to mix the stain well prior to opening. Use protective gloves and safety glasses and cover any plants, landscaping, concrete or windows you do not want to get stain on. Apply a light coat on one or two boards at a time or in a small section. It is best to work from one end of a board to the other then move on to the next board. This will help reduce overlap marks.

If one coat soaks in fairly quickly a second coat may be applied. A second “wet on wet” coat should be applied within 30 minutes of the first coat. Be cautions of over applying TWP Stain. If excess puddles of wet stain remain after a reasonable amount of time and or not being absorbed do not allow the stain to dry. Wipe away the excess with a clean stain rag or back brush the stain to blend it in. Leaving excess stain on the surface to dry will result in an unappealing shiny finish.

I’m confused about the “wet on wet” guidance. The recommendation is to apply a second coat after 30 minutes, most likely when the most recent stained boards are still a wet. So on a deck, wouldn’t it mean that we may need to walk over the most recent stained boards in order to apply the second coat so soon? And since it may take about two hours to stain the first coat by brush, could I re-start when completely finished the first coat all over? Why the wet-on-wet suggestion? Thanks

Cleaned my deck over two weeks ago and weather not cooperating. It maybe awhile before I can stain/preserve it. When the weather does cooperate can I do a lite powerwash to clean? Or do I have to use a deck cleaner again? What does the temp and humidity level need to be for application?

Just properly cleaned deck and now the weather is not complying. How long do I have to put stain on? How long will deck stay clean (neutralized with oxalic acid)?  
How long should deck dry after mild rain?
How long does it take for stain to dry and then cure?

I have an outside handrail that I will stain (no previous stain so will clean prior ). I remember reading a recommendation to not stain all sides of the wood because of possibility of lack of air flow preventing drying. Would that also apply in this case where a handrail is completely open to the elements ( except for where it mounts to brackets)?Thanks in advance for your advice!

I am needing to stain a pergola to match the fence (using TWP dark walnut). The fence (made of pressure treated lumber) is only a couple months old whereas the pergola is several years old and wood has turned the typical gray. Was planning on mixing the stains and testing to be able to achieve the same/or very close for the fence and pergola. Can I do that? Also, do I need to do anything other than power wash the pergola before staining?

My contractor used TWP last year when he built the new redwood deck.
I would like to put another coat of stain on this year as it already looks weathered… reading this stuff, do I have to strip my wood EVERY year that I want to reapply a coat? What happens if I just put another coat on top?
Also, how can I clean the deck without harmful chemicals or bleach for the plants and wild animals below the deck?

What happens if you don’t prep it?  I recoated my pergola and fence with the same TWP that was used the prior year (before I read all of this) and it looks great.  I’m wondering why it is so important to clean and prep if the wood isn’t that dirty?Thanks.

My deck is situated over a cloth-type covered lower deck. It can’t be removed and would be very difficult to cover.  The biodegradable Gemini cleaner says to wet down all vegetation before and after using the cleaner… will the cleaner ruin my lower deck covering?

My plan is too re seal/stain my deck with the same TWP product (picture) that I’ve used before. One note – the deck boards were some type of pretreated to provide maintenance free decking.
The contractor that applied the last time over applied the product which left white spots of residue (picture) on the deck. Should I fully remove the old product from deck boards before I add a new quote?  What will thin out or remove the white residue spots as pressure washer didn’t fully remove them?  Am I using the right stain sealer product? Any other recommendation would be appreciated.

I have a pretty large lower deck that we are gradually replacing all deck boards. It has been 1 year and I will be staining a portion of the new deck. The smaller upper deck only needs to be stained. I have no idea what brand was used originally on either deck. How should I prep the upper deck and which product would you recommend? We live in mid Missouri on a lake. Also would you recommend your products to protect marine board?
Thanks-
Laurie

So i just finished staining my deck & not sure whether or not to apply a 2nd coat. I finished it yesterday and have allowed it to dry. I wouldn’t say the 1st coat soaked in immediately but seemed to be dry in about 4-5hrs. Should i apply a 2nd coat or since its been 24-36hrs would it be pointless to do so?

We’ve sanded over-pigmented water-based preservative (Okon) off 38-35 year old redwood clapboard siding. TWP instructions rec washing after sanding old wood to remove dust. But 35 year old nails are producing iron stain when stripped wood washed in sample area. What is best alternative to washing, to prep for application of TWP? Recs for removing iron stain without having to redo whole boards also welcome.

Thank you, but not a very useful answer. I know that it’s rust which is why I don’t want to follow TWP instructions to wash siding with water. Never had any nail rust on this siding in 30 yrs of weather. It only happened after following TWP’s instructions to wash freshly sanded siding before applying stain. I do not want to apply water directly to any more of the sanded boards for this reason.

So I was asking for alternative, non-water methods of adequately removing dust on all the siding before applying finish. I also suggest that TWP not advise customers to wash sanded siding, as TWP1500 instructions do, without testing for nail reaction in unobtrusive spot.

I am confused. You recommend TWP 1500 as best for a new deck, however, in all these comments, everyone is using TWP 100.
We need to stain a very large new deck built with pine. Can you please tell me the best stain?

I have a douglas fir front door that showed signs of weathering. I don’t know what the original finish was. I sanded the surface, removed the dust and applied TWP cedar tone. Before appling TWP the door had a uniform appearance. When I applied TWP the surface has dark and light blotches. What would you recommend to correct the blotching? Thanks for your assistance. P.S. we used TWP on another property and It worked great!

I applied series 120 last year and just didn’t realize I was supposed to add a cleaner before applying a new coat this year. The second coat makes the deck look wet, but it’s actually dry. I still have about a quarter of the deck to do. Should I just proceed with adding the second coat over my deck stain or should I clean the the whole Deck with Gemini and restart?

Appreciate the help.

It is Sunday. There is rain in the forecast on Tuesday and Wednesday. Can I clean and brighten my deck today or tomorrow (Monday) and then apply TWP later in the week, after the rain stops? Or do I have to apply the cleaner, brightener, and then stain with no rain in between between applications of the brightened and stain?

I finished applying TWP200 late last night around 9:00pm. This morning everything looks great, except they’re a few areas that I missed. Is it ok to try and apply over those specific areas?

Ok, but the first coat was applied 12 hrs ago, so this would not be a wet on wet application. Will there be any issue with the second coat absorbing into the wood?

We used several gallons of TWP 100 stain last year on our deck which had been built in 2018. We had prepped it with your cleaning system. We have a person scheduled to put the second coat on in May. There are a couple of small, black “streaky” areas on 2 of the top railing boards. Do we need to wash the deck before the second coat?

We have a cedar deck and have found that renting an orbital sander is a better way to clean the deck than power washing or deck cleaners. They just leave the deck surface rough. It takes only 2 hours to sand a 700 sq ft deck. Then use a leaf blower to clean off the dust. It is ready for sealing right away without waiting for the deck to dry out. We use TWP-1500, cedar tone. We love the look and get many compliments on this 34 year old deck! Thank you TWP.

I was told by a contractor that foam is the best roller material for applying TWP. Is this true? If not, what sort of roller should I use?

Thanks

Thank you. My job entails staining the ‘ceiling’ of a roof overhang, so using a brush would be very messy. I’ll try the pads.

Hello,
I power washed my deck 12 hours ago (full of mold, etc.). Today I was planning on using the gemini clean/restore. Do you apply step two solution immediately after completing step 1? Also, how long before I can apply stain after step 1 and 2 are complete?

Hello,

I am looking to refresh our deck and we used TWP 1500 between 1-2 years ago, and want to apply a fresh new coat of stain, Do I have to strip the older TWP 1500 off, before applying a fresh new coat, or do I just need to apply a deck cleaner and power wash it clean, and then apply a fresh coat?

Thank You
