What is the Shelf Life of TWP Wood Stains in 2021

Shelf life of TWP Deck Stains

After an exterior staining project with TWP, Total Wood Preservative Stain you may have some extra leftover. Or you may have bought some TWP wood stain intending to use it and just haven’t got around to it. Whether you have some leftover or the season ended before you could use it, TWP wood stain will store and keep fresh with proper care.

TWP Wood Preservative has a shelf life of several years if it has been unopened. So if you ran out of time at the end of the season do not worry, you can still use it when you are ready. If the TWP stain has sat around a while, it is recommended to take the stain to a paint store and have them shake the cans up before using them.

If you used TWP stain and have some leftover, the extra will last 1-2 years as long as the lid is completely resealed. If the lid is not sealed properly evaporation of the stain solvents will occur and the stain will become thicker and be rendered useless. Be sure the lid is completely sealed to stop any evaporation from happening. This will ensure the leftover TWP can be used on your next wood maintenance project.

Tips for Storing TWP Wood Stain

When storing TWP stain it is best to keep it in a cool dry place preferably at room temperature.

It should be kept out of direct sunlight if possible.

Oil-based stains like TWP can be stored in colder weather and in some instances even below freezing. The oil formula will simply thicken, unlike water-based stains that would actually freeze solid. With that said if you have a choice and can bring the stain into the basement or partially heated garage for the winter that would be best.

If you have several partial cans of TWP stain it is best to combine them to make a full can. The less empty space in the can the better. The air above the stain will cause skin or gel to form on the surface. This can be removed but it is better to have one full can and just a little left in another than to have two partially half-full cans of TWP stain.

Be sure the lid is on tight to eliminate the solvents from evaporating.

As soon as you finish a project it is helpful to mark on the lid what you used the TWP stain for. This way when you use the stain a year or two later you won’t have to guess.

Follow these storage tips to increase the shelf life of your TWP wood and deck stains and they will last for several years saving you money.

I have about 2-3 gallons in a 5 gallon bucket left over from staining a fence. I plan to use it in the spring for a maintenance coat on my deck. I have 2 empty 1 gallon cans, but they might not hold all the stain I have left. Could I use a milk jug or some other plastic storage container for the stain that won’t fit in my 1 gallon cans? Will the stain soften the plastic and make an awful mess? I have some empty wide mouth plastic jars (peanuts)…..would they work?

I just stained my deck with TWP 1500 and a friend spilled citronella candle wax on part of it. I’ve read that once it’s dry you can scrape it with a credit card or spoon etc, and then use paper bag and iron to get remainder out of grooves…will this ruin the stain? What is the best way to remove it without ruining my recent stain job? The wax was spilled across about 10×10 inches of my deck 😡any suggestions would be helpful. Thanks!

So you have no recommendations for removing the wax from deck? I just scraped most of it off and don’t think I removed much of the stain. There are some stuck in the wood grain and worried if I use an iron and paper bag to remove it that the stain will heat up and come off onto paper bag too. I literally just stained last week, and would prefer to not have to use the extreme methods Of using paint thinner or start over. Could I do the iron method and then reapply a thin coat of stain?

I live in Pflugerville TX, about 10 miles north of the
Capitol city of Austin. The low temps here at night are in the high 60s low 70s. Daytime highs are 91-93. I am planning on using the Restore a Deck and TWP 1500 on my deck both already purchased. Starting the stain around 7 or 8 am the deck stairs will begin to be in sun about 11-11:30.
The entire deck will be in sun about 1pm with full shade at 6-6:30. I am concerned about the sun on the new stain right after it is applied for an extended period of time of 5-6 hours. Please advise. Thanks.

I just finished applying the pecan stain a few weeks ago. My deck is 2 years old. I used the cleaner and brightener as directed with a power washer and applied the stain wet on wet. It looked wonderful until it got wet. It beads up perfectly but the water is leaving white marks. I do have hard water, but not certain if I should reapply stain on these areas or ??? Thank you

We ordered a 5 gallon and 1 gallon can of 1500 in July. We are now finally ready to apply the stain. Do we need to take the cans to a local paint store to shake or is stirring the cans adequate?

That was what we had done originally, but we had a million bugs come land in the stain while it was wet. I contacted this website and I thought was instructed to sand and restrain to remove the bugs. I’ll have to look through the posts from last year

Is my resealed 5 Gallon 1500 Stain still good after 1 year? I hammer the tabs down really well around the entire thing. It was stored in basement that doesn’t get too cold. I think when tipped it that it didn’t leak at all so thought seal was good.

I haven’t opened it yet but hoped to use it soon for a new coat this year.

Is it still good? How will I know?

After reading about storing extra stain, we have over half of the 5 gallons left because while it worked wonderfully on our main deck, we intended to use the stripper on our boardwalk and stain it the same, but the other brand solid stain must have had some paint in it, so 30% wouldn’t come off. Even considered putting it on what was uncovered, but decided not to waste it. MAIN QUESTION IS: The 5 gallon bucket mailed to us was extremely dented (the middle was dented almost to the middle of the can. We used a rubber mallet to seal the lid, but I’m concerned it might not make a good enough seal, or that there might be pinholes where the metal bent so much. Will it last like you said? Any suggestions?

It’s not quite that simple. Just prying the tabs doesn’t work. I had to use heavy plyers and pry the tabs back to 90 degrees of the pail…..but I got it and appreciate your reply.

Is there a mildewcide that could enhance TWP 1501 Cedartone stain? Replaced the product the builder had used on Cedar Screen porch with cement pad 6 summers ago with TWP 1501 Cedartone 3 years ago. Results less mildew with the TWP but still shows mildew.

We are going to be putting up New Cedar siding on our home. The cedar is tight knot smooth dried cedar siding. Because it is dried can we put two coats on. We were thinking on dipping the wood and then once its up put another coat on the outside. Is this possible with the TWP?

What is the consistency supposed to be? We just reopened a gallon can of the 100 series that had been stored in a closet for a couple months and it seems really watery. We just want to make sure that is correct before we go using it.

Is there a trick to opening and closing the 100 series 5 gallon bucket? I had a heck of time getting it open and now that my project is done, I want to make sure I seal it properly so I can reuse when needed. Is there a special tool to use?

Can TWP 100 stain be stored in plastic containers such as an old hydraulic oil 5 gallon bucket? The seal on my metal lid is deformed and I’m concerned it is not sealing completely. The buckets for the oil have been cleaned and have a good sealing lid.

I just purchased 2 gal. Of TWP 101 ceder stain the dealer told me he had shaken can to mix but when I opened can all color was at bottom. I only have paint stir sticks and it is almost impossible to get color from bottom of can to mix ???

With the stir sticks or a drill mixer will work.

If the lid is on tight and doesn’t leak store the can upside down (Lid on the bottom). Nothing can evaporate through a fully sealed can. It is an old trick many plumbers use for their leftover epoxy and cements. Helps things last years and ensures it will always be ready when you need it!

I stained my pressure treated wooden deck with 1515 Honeytone in 2012. Love it!!! Can I put another coat on this year without stripping it?? If so what would the prep process be?

Yes but you will need to prep first with the Gemini Restore Kit first and you may need two coats since it has been 3 years.

I have stored some TWP 100 for 2 years, a 5 gallon pail 1/2 full. It has thickened some about the consistency of an interior latex paint. After thoroughly mixing I have stained a small section of cedar siding, it looks good, but should I be concerned with the change of viscosity?

Yes it needs to be shaken or stirred well. 2 to 3 years if unopened.
