Best Prep for TWP Stains

Best Prep for TWP 1500 Stain and the TWP 100 Stain for Enhanced Performance and Appearance.

When staining a new exterior wood surface with TWP, or refinishing an older one, it is best to correctly prepare the wood. Wood prep is important with any stain and TWP is no different. Using the best prep methods will certify a quality product like TWP stain performs as expected. This helps guarantee a long-lasting, beautiful finish.

To give your wood surface the best prep for TWP stains, the wood needs to be cleaned and brightened. For the best results, use Gemini Restore Kit. Gemini is the largest manufacturer of TWP stain, so they know what it takes to get the best prep possible. Gemini Restoration Kit is a two-part “eco-friendly” system.

Prepping TWP Stains

Step 1 is the wood and deck cleaner that gets down into the wood for a deep clean. Following the cleaner’s directions, use a scrub brush or pressure washer to cleanse the wood. This will rid the surface of any dirt, grime, or gray wood fibers to ensure the best prep.

Step 2 of the Gemini Restore Kit is a wood brightener that will “brighten” the wood and neutralize the cleaner at the same time. This warrants the best prep of the wood surface for TWP stains to ensure excellent protection.

If the wood surface has an existing stain on it that needs to be removed, use Restore-A-Deck Stain Stripper. Besides removing dirt, grime, and grayness, RAD Stripper will remove old failed stains prior to applying TWP stain. The RAD Stain Stripper is a two-part system similar to the Gemini Restore Kit. Apply the stripper and clean the wood accordingly, then apply step 2 the wood brightener. Once the wood surface is cleaned and brightened, let it dry for several days before applying TWP.

This is the best prep for TWP stains and a proven method to help ensure good stain performance. Do not risk premature stain failure with inferior wood prepping. When the surface is prepped correctly, the TWP stain will give you a durable, long-lasting finish.

I applied TWP 100 Series stain to my pressurized wood deck about a year ago. The deck had been installed the previous year and this was the initial staining, which I prepped with the Gemini prepping products. I am considering restaining again now under the theory that I will get even deeper penetration and avoid having to restain for several more years. I have 2 questions:

–does this sound like a good idea?

–what type of prep do I need to do now? Same as before? Less?

Can you sand the deck after you have cleaned and brightened but before you apply stain?

Deck is 3 years old. Had lots of black discoloring and algae. Light sanding, then used Gemini cleaner and brightened. Staining with same twp redwood as before. Will it cover evenly or blotchy with some spots left of stain? Any tips to make sure will look even, 2 coats wet on wet.

Before using the restore kit does the deck need to be dry. We are dodging rain and trying to get the deck done. Also how much time do you need to wait if any between step 1 and step 2. Last question how long can you wait before restaining max time. I know minimum 48 hrs. Thank you

I have my deck stained professionally two years ago using brightener and TWP 101. Now I’d like to do it myself, again using TWP 101. How to prep it before staining? It’s not clear either Gemini cleaner kit or RAD stripper. Could you please give me some guidance on how to prep properly? Thanks.

I plan to use the Gemini cleaner and brightener. Does the cleaner need to dry before using the brightener or do them at the same time? Also, how long should I wait to stain? Thanks

Building a patio table from construction lumber that will be on a screened in porch. Roof overhead and minimal sunlight exposure. Planning on using TWP 1500 stain on the table, can I apply a marine grade varnish over the top of the stain?

I cleaned and brightened my fence two day ago thinking I would stain today. We are having some rain now so I must wait to stain.
How long is the window between clean/brighten and staining? Is there a point that is too long and I need to clean/brighten again before staining? I am using 1500.

2,000 sqft deck is over a covered patio so anything I use to strip/prep needs to not destroy the vinyl panels under it (they have holes and will drain). Most of the deck has no stain left like picture 1 but protected areas and corners still have stain like picture 2. Do I need to sand or will Restore-A-Deck strip the old stain without damaging the vinyl underneath? Not sure what prior owner used but I found an old can of Cabot in the garage. Planning on using TWP 100 (South Carolina).

We have a 40 year old deck which has been stained few times over the years. It is time to do it again, time flies. I have come across your product line and am very interested in using them. I have read about the RAD, and brightner ,at what point would I power wash? Which stain would I use, we’re just North of Chicago in Wis. We would like to match the existing color. Thank you Marty and Dar

Hi there…I am getting ready to prep a deck for a “freshen up” application of TWP stain. I have the Gemini Restor-A-Deck product which I did purchase from you. The current TWP deck stain has been on there since spring of 2019 and the current condition is documented in the attached pictures. It was initially applied after I had belt sanded the entire deck. The current stain does retain some water repellent quality as is clear when it rains. You recommended Restor-a-Deck as the prep in response to my previous inquiry. My question now is whether or not I should… Read more »

Thanks for your great Q&A site. There are many similar questions here, but mine is a bit unique. We put a completely new top surface on our multi-level deck in cedar 3 years ago. We used a competitor’s product for the first 2 years and it was not positive. It looked great for a month and then started deteriorating very fast. We thought that it was the product, so we had it sanded down and re-done 2 years ago, after the first year. After 2 years in a row of that, I went into research mode to find THE BEST… Read more »

I applied 2 coats of 1500 on new cedar decking last summer. Horizontal decking is fading quickly and I want to install maintenance coat of same product and color. Can I just applied Restore-A-Deck Cleaner (not Brightner) and then stain; or do you recommend strongly to use the Brightner after cleaning?

I had Australian timber oil used on a deck that is just now three years old. The old stain was sanded off. I would like to use TWP 100 but see that you recommend stripping rather than sanding. Would I get good results if I were to apply TWP 100?

my deck has TWP 1500 Natural on it now applied in 2017 and it still looks good except for a few areas that are exposed I would like to put another coat on it this summer. My question is do I need to use the cleaning and brightening prep chemicals on it again, or just need to wash it good. thanks

Hi, I coated my deck with TWP 1500 Pecan two years ago after sanding, removing the previous flaky brand, cleaning, brightening, eyc.–the whole 9 yards! I would like to re-stain my deck this spring. Do I really need to remove all the existing TWP stain before doing so? Or would it be enough to clean the deck well and then re-apply? Thanks for any information you can give me. I love all TWP products!

I can’t find where now, but I thought I read that you should clean and brighten (Part 1 and Part 2 of RAD kit) all in the same day. I’m not sure I can do both parts in one day. Does it hurt if the wood dries for a day or so between cleaning and brightening? I know the wood has to dry before staining, but wondering about between cleaning and brightening.

I have a 5 year old deck that I stripped and prepped. I’m planning to apply twp 100 stain. We have had the wettest year I can remember and it is going on 4 weeks since I have prepped my deck. At this point, do I need to reprep the wood again? It still looks nice and bright and ready to stain. thanks!

I’m thinking of using TWP to maintain some ikea APPLARO furniture that’s been sitting outside for a year. It’s acacia wood with some type of penetrating oil sealer applied. Should I start with something like RAD first in that case, especially if a pressure washer is out of the question?

We are the third place TWP Stain winners from 2018 and are planning to add a maintenance coat this weekend. Thanks for an awesome product! I have attached a few pics of the weathered areas of our deck and are asking which cleaning method would be best advised to re-coat our deck. The color is TWP 100 Cedar 116. These areas are in areas that get a lot of midday sun and have had problems with mold and algae build up over time. Will we have to completely strip the entire deck to get a consistent finish or will the… Read more »

Three years ago we applied TWP stain to the log siding of our house. It’s time for a new coat – if we’re not changing colors or stains do we need to do the Gemini Restore kit before applying TWP this year? Or would simply power washing be enough prep?

In MN. Last year I rebuilt part of the deck with new wood. Will use gemini kit to clean and brighten before applying 100. I stripped the old part last summer, used gemini and applied 100. For maintenance coat I should use gemini to clean and brighten? And just one coat of 100?

3 years ago, I stripped, cleaned and brightened my large deck , then applied TWP1500 in Cedartone color. I am planning on cleaning and using the brightener again this spring, (not stripping) however, this time I want to use TWP100 in the same Cedartone. The deck is currently very faded . Is this the correct process to re-stain if I am switching from TWP1500 to TWP100?
I’m in Texas, deck faces south and catches extreme afternoon sun and heat.

My deck has TWP 1520 Pecan stain which was applied 3 years ago and its time to re-stain the deck. I would like to know what needs to be done to the deck before applying the same stain? Do I need to strip the stain or will cleaning and brightening be good enough?

I live in northern Washington state the temperature during the next five days is predicted to be mid 60s with lows in the low 40s no rain. Fog in the mornings sun in the afternoons. My question is, are these conditions too cool for preparation with restore a deck and a maintenance coat of the TWP 1500

Hi,

I’m getting ready to stain the exterior siding on my house. We removed the previous coats of stain and varnish by sanding down to bare wood.

I stained a few boards with TWP to test various tones. My plan was to pick a color and take the samples off by sanding.

However, when I tried to sand it down the wood completely filled the sand paper immediately – picture below.

What’s the best way to remove those few test samples of TWP 100.

I had a 4 month old Alaskan White Cedar deck that I stained last year and had a problem with when I went to clean it this Spring. After trying many options, I power washed it, let it dry, completely sanded it down, and applied your brightener. That was a little over two weeks ago and we’ve had rain consistently enough that I haven’t been able to apply the TWP 100 stain. Dry weather is forecast. What do I need to do to re-prep? Thanks!

I am preparing some red cedar I obtained from a sawmill in Ky. for a privacy fence in Fl. It is rough cut but I am running it through my planer to improve it’s beauty. Is it necessary to clean such fresh wood and will one coat of TWP 100 be adequate?

I have used the Gemini Restore kit on 10/2 for our cedar fence. We had an insane amount of raining days that we never were able to achieve a 48 hour dry time with a 24 hour cure time. Is it too late to stain on 10/19. It will be 3 days after the 2 week period.

I have an older deck with a worn coat of another brand of semi-transparent stain. I’m planning on sanding rough spots before stripping and brightening, then applying TWP 1520 after it dries.
Does the entire deck need sanding for the stain to soak in properly, or can I just do the rough spots?
