I have about 2 gallons in a 5 gallon pail in the basement. I used it about 5 years ago and was wondering if its still good. Is there a way to test it before I use it.

I know that the best outcome on my Deck refinish project is a function of Prep and Product. I’m willing to do the work on the prep, and it seems you have an excellent product and know what it needs better than me, therefore can you advise the best preparation process for the following situation: The deck was new in 2006 and the contractor stained both sides with Sikken oil based product. It seemed to lay on top of the wood and didn’t last long in the sun before checking and popping off. After that fiasco I had to sand down the entire deck to bare wood. At that point I applied a transparent oil based product purchased locally – Messmers UV Plus. It soaked in well, but a little thin for sun areas. My wife got sick a couple years ago and I missed the crucial season it needed to be reapplied. That brings me to now. I’m ready immediately to begin the prep. The deck is dull, and has many areas that have completely lost protection and turned grey. Can you help? Do I need to sand it down again? Do you have a prep system/ products I can use? Will your semi-transparent product be the right choice to keep my decks looking good for many years – with regular cleaning and reapplication on my part, I presume? Really ready to get on this with the right prep and products. Willing to pay extra for a quality proven product – the cost is in the labor.
Thank you,

I followed instructions on stripping and brightening using Restore-A-Deck but it left some old PPG semi transparent stain behind and some of the wood raised (I had to get aggressive with power washer to get stain off). I am sanding over everything now to remove remaining stain and smoothing raised wood. What steps do I need to do before putting down the first coat of TWP 100? Do I need to mist the wood? Is there a preferred grit I need to use? Any other things that might work differently?

Thank you for your quick reply. I did apply the Brightener after using the stripper, which I thought was to neutralize the stripper. What is the reason for applying another coat of brightener?

I am requesting a sample of your RAD paint and solid stain remover. The lengthy description below lays out my circumstances behind my request for a sample of your most aggresive solid-stain remover. I am a woodworker with a great appreciation for the beauty of wood and wood grain. After unsuccessfully trying to maintain my pressure-treated deck with semi-transparent and semi-solid stains in earlier years, I reluctantly used a Behr solid stain (paint) on my deck attached to my high-altitude home (7000 feet) in Colorado about 2-3 years ago. I slavishly followed the appication directions for the product. As you might expect the UV from sun is by far and away the most brutal weathering agent on our deck. And our main deck has a west exposure that soaks up afternoon sunlight. After vigorous preparation, including renting and using a heavy-duty floor sander, as well as replacing some of the more weathered boards, I applied Behr’s solid stain and have had catatstrophic results. Despite following all instructions on the solid stain, within 6 months I was getting widespread peeling on at least 40 percent of the deck. It is much worse today. Even on the completely shaded eastern exposure of a smaller deck, under a roof that blocks all direct sunlight, I am getting significant peeling of the stain on at least 20 percent of the deck after 2-3 years. Obviously I need to start over and attempt to remove the entirety of the existing solid stain before I attempt anything else. Please send me a sample so that I might see if it is worthwhile for me to pay at least $270 for a five-gallon container (or more–I haven’t estimated the surface area of the decks and railings yet) of your product. Thank you.

3. Remove Cleaner with pressure washer
4. Apply bleach solution 1 to 4, wait 15 min
5. Remove bleach with water hose
6. Apply Brightener wait 20 min
7. Remove Brightener with water hose
8. 48 hours for drying

Last Wed. I stained our deck with twp 1500. We applied our first coat to new pressure treated wood that seasoned for over a year on this new deck 14 months ago, same stain. Followed all the directions, cleaned & brightend with RAD products, rinsed for an hour after brightening, waited for a week, applied stain under perfect conditions and wiped off any excess promptly. Cured in dry warm weather for 4 days, then we got our first rain, and now I am noticing an oily slick on certain areas, see the photos. The deck is not tacky and it appears to dry without leaving a residue, but don’t want to track it in the house or have the dog walk through it. What is going on, and will it resolve on its own or should I do something? Thanks

I have three cedar garage doors, 9 years old. They face south, so they get some sun, particularly in the winter. They were originally treated with Australian Timber Oil, but that finish turned dark after a few years. They were stripped and brightened with your products. All the original oil came off, but they were a little rough so they were thoroughly sanded. Then they were treated with your 100 Honeytone product. The finish darked after two years, so they were stripped, brightened, and treated again with your 1500 product. It’s now two years later, and they are darkening again.

See the attached photo. The doors in the center and on the right were treated 2 years ago. The door on the right is usually up, so it doesn’t see much sun, and it still looks good. But the center one has darkened considerably. The one on the left was just stripped, brightened, and treated again.

What’s causing the darkening, and how can I slow/stop it? Striping/brightening/treating every two years seems too frequent.

I believe when I ordered some samples, I was told that the price of the samples get applied to purchase of full product. I am in the checkout process, but I do not see any credit applied for my sample orders I had previously placed. Do I need to do something else to receive this credit, or am I mistaken about the credit? Thanks.

I have replaced my PT SYP decking 6 months ago, It has dried and weathered adequately at this point. I want to use your semi-solid stain. Prior articles addressed using TWP 100 or 1500 inre prep. Should I do any special prep other than a light pressure washing to remove any grime? Also, the railing will be replaced with KDAT lumber to guarantee minimum warpage. It is kiln-dried already. Any prep? Lastly, the exposed understructure framing was stained with TWP 100 several years back. I want to cover it the semi-solid as well. Any restrictions there?

I have 575 square foot redwood deck. All the joists were replace and variety of redwood was used (some from the original deck 1984, some from 2000 and some that is at least two years old). I power sanded using 36 and 60 grit. It has been 14 days since the deck was sanded and dust was cleaned it with 60 V blower. I applied a sample of redwood 1502 to a part of the deck and put a second coat on it 15 minutes later. The stain is almost dry after 4 hours. Do I need to further prep the deck?

Hi, I have a deck that has been previously stained with a latex semi-transparent stain. (long story, bad contractor) I’d like to put either TWP 1501 or a similar color 100 semi-solid series over it. I am using 1501 on my cedar siding. A couple of questions:
What prep is needed for the deck?
What is the closest 100 series color to 1501? I looked at Cedar Mulch and Super Cedar but they do not seem very close to 1501.

Thank you!

After installing a 900 sq. ft. redwood deck two years ago, I prepped and stained it with one coat of Superdeck Transparent Stain (redwood color). There are some high traffic areas where the stain seems to have rubbed off with bare wood showing.

it seems as though that company is no longer in business, so I want to switch to a TWP product—-not the solid. In that case, do you have a recommendation of which of your products would work well for me? I live in a suburb of SF Bay Area, so the summers are hot and winters do not get below 30.
Lastly, would using a cleaner and, then, a brightener before staining be OK?

Thank you.

Do you still make the semi-transparent stain?
Is that product #1502?
I don’t want the semi solid. ThT sounds more like a redwood colored paint.
I want the grain to show through.
Also, how do I order a couple of samples of redwood and rustic?
Thank you.

I stained a 14 year old deck with the semi-solid series. The old wood was sanded and power washed prior to staining. There were a few new pieces of wood as well. I noticed after stain dried that the deck railing was darker than the deck floor. It’s too late to apply a second coat wet-on-wet. Can I now apply a second coat on the deck flooring?

8 months ago

Are you able to advise on what color in the TWP 200 series gives just a natural “wet” look similar to the TWP 115 ? It’s $100 USD to get a few samples shipped to Canada and photo galleries of the 200 series seem to be lacking across the internet. Thanks!

I originally applied TWP 100 stain first time to a new wood deck 4 years ago and have applied 3 maintenance coats over the same period. At what point is it recommended to stop with the maintenance coats and strip the old stain and start over? Also, should I strip the old stain first and the clean and brighten before apply the new stain. I will be sticking with the same 100 stain color as the original coat if that makes a difference.

Thanks for answering.

Our contractor applied one coat of TWP 100 Cedartone to our deck about an hour before a heavy rainfall. We asked them to fix it, so they returned several weeks later and added another coat, which is now pooled on the surface of the wood and is not drying. This was done despite our effort to direct them to your website for proper instructions first. Can you please let us know how this should have been handled and what steps can be taken to correct the issue? Thank you for your help!

Thank you for the prompt response! If the second coat does cure, will there be any risk of the wood rotting prematurely due to the water exposure following the initial coat?

Thanks. We were not confident with using a funnel, as our sprayer container is very small and the volume of stain pouring out is high from a 5 gal. We got a battery operated transfer pump. Worked great. The stain goes on super easy with the sprayer and back brushing.

Guys stained cedartone 1500 on railings yesterday. I noticed a glistening after 40 mins – so and went to wipe off what looked like overapplication and was told it wasn’t necessary so I stopped. 8 hours later I thought I’d check to see if spots had dried it was still wet and some had a gooey look. Any suggestions? There were about 30 spots that I found after more carefull reviewing. If it is over application – how is this repaired? Also, this cedartone looks more like redwood. Thoughts?
