Protecting your exterior wood surfaces from harsh elements is the key to enhanced appearance and increased lifespan. Unprotected wood will rot, decay, and discolor quickly from moisture and harmful UV rays. To protect your wood surfaces from Mother Nature, the wood must first be cleaned and prepped prior to applying a wood preservative.

The Gemini Restore Kit is a powerful deck cleaner and brightener system. The 2-part restoration system is Eco-Friendly and 100% biodegradable. It is a concentrated powder formula that preps wood surfaces prior to staining or sealing. This easy to use system is perfect for the do-it-yourself homeowner looking to increase the appearance and protection of most any exterior wood surface.

 To prep a wood surface using the Gemini Restore Kit use these easy to follow step-by-step instructions.

  1. Air temperatures should be between 45-90 degrees Fahrenheit. Be sure to move all furnishings, potted plants, and outdoor décor from the immediate work area.
  2. Cover and protect landscaping, plants, shrubbery, windows, doors, etc. or pre-wet with clean water.
  3. Follow the Gemini Restore Kit instructions for mixing the Wood Cleaner (step 1) in a clean 5-gallon bucket until all the solid crystals are dissolved thoroughly.
  4. Lightly moisten the wood with clean water. Use a pump sprayer or scrub brush to apply the Gemini Wood Cleaner. Allow the cleaner to soak on the surface for 5-15 minutes. Make sure the wood remains moist by misting it with clean water.
  5. Scrub with a brush or use a pressure washer to remove graying, dirt, and grime from the wood surface. Be cautious not to use extreme pressure.
  6. Once the wood surface has been washed, rinse the surface along with the surrounding landscaping, windows, house siding, etc.
  7. Mix the Gemini Restore Wood Brightener (step 2) according to the instructions. Apply to a still wet wood surface using a pump sprayer and let soak for 10 minutes. Rinse off thoroughly with fresh water.

The clean and prepped wood surface should be allowed to air dry for 1-2 days prior to deck stain or sealer application. Gemini Restore Kit is best for gray and weathered wood surfaces and may not be best for removing old deck stains or sealers.

    12x26 Cedar deck was new in 05/2020. Picture is after RAD.
    1. Wet on wet or one coat using TWP 100 Cedartone? Using stain pads on deck, brush on railing.2. After RAD (took 3 cleanings using cleaner and pressure washer, used all of the cleaner) and waiting 48hrs I had to cover deck with multiple tarps due to rain forecast and rain. Now forecast is maybe a week out before I can stain. What do I need to do?3. 6 steps not shown were not tarped. Can I do brightener only.4. Why is cleaner instructions given in ounces and brightener given in cups?

    I have cleaned and brightened deck twice now.  Due to weather and family matters, it has been more than 2 weeks since last prep - 4-5 weeks.  What will happen if I stain now as I want to get done prior to change in weather. I am in Wisconsin.

      You need to redo prep. Light cleaning will suffice.

    2 years ago we stained our old pressure treated pine deck with TWP 1500 series stain. We now (2 years later) would like to apply a maintenance coat of the same stain, same color, as there has been significant fading in the area exposed to the elements (not those under roof). We live in Ohio, so it was subjected to heat & sun, rain, cold, snow & ice.
    It is not entirely clear to me the best prepping cleaner. Sometimes cleaning with detergent & water seems to be sufficient/recommended. Most of the time the Gemini Restore a deck cleaner+brightener kit is recommended. The Gemini Cleaner directions recommend 6oz/gal for light cleaning, 8 oz/gal for medium, and 10 oz/gal for heavy cleaning. 
    Is soap & water enough in this case, or do you recommend the Gemini light cleaning level since we are using the same color 1500 series stain? Or heavier cleaning solution?
    Thanks.

      Use the Gemini Kit at normal ratios of 8oz per gallon.

    Hi, building a Doug fir pergola above a new concrete deck.  Will the cleaner/brighter stain or discolor the concrete?  What precautions to take? Thanks in advance.

    Is there a minimum air temperature that you can do the cleaner/brightener? Is there a maximum amount of days you can wait before staining? (If you wait too long, should you prep again?). Just trying to judge what we should do with the upcoming weather that we have. Thanks.

    Are there any directions for the restor a deck kit? This page tells me to "Follow the Gemini Restore Kit instructions for mixing the Wood Cleaner". That doesn't help. I visited this site because I can't read the two point lettering on the actual kit.

    Here are my plans for this week to stain our porch. Let me know if I should change anything.

    The house and porch are two years old and has never been stained before.



    Tuesday- have a guy coming to power wash the porch

    Thursday- I will be doing the Gemini cleaner/brightener kit

    Sunday- I will be staining the deck with a brush, I assume it will only need one coat since its a fairly new porch?

    Anything you would recommend changing? Thanks!

      You use the Gemini Kit while pressure washing. Just one coat for newer wood is correct.

        Kevin Roach · 09/14/2020
        Ok, so I haven't received the kit in the mail yet, it comes tomorrow. So this might be self explanatory once I receive the product, but what instructions should I give the guy.

        Is this correct?

        Spray cleaner on porch
        Let sit for 10 minutes
        Powerwash the porch.

        Apply brightener
        Rinse the porch

    I used the Restore-A-Deck kit a couple of days ago and it did a fantastic job! However, I have the black plastic connectors for the balusters and they have left a white residue that I can't get off. I've tried multi-purpose cleaner, Mineral Spirits, Goo Gone, CLR, to name a few. Do you have a recommendation?

    can the gemini cleaner and brightener be applied on separate days, or do they need to follow one right after the other immediately?

      Best to do the brightener right after the cleaner.

    How do I need to prep a deck for TWP if in past years I have used Flood Solid Color Stain? I have pressure washed and quite a bit flakes off.
    • We will reply to your comment shortly
      TWP Stains · 05/27/2020
      You will have to power sand to remove a solid stain.

    Last spring I applied TWP 100 to our pool deck. This year it appears to have faded. I’d like to freshen it this year. Do I need to clean and brighten with the Gemini restore-a-kit before I reapply a new coat of TWP or just clean with Gemini?
    • We will reply to your comment shortly
      TWP Stains · 03/22/2020
      Clean and brighten for the prep when applying a maintenance coat.

    Can I use this on my garage door as well? Door hasn't been stained in at least 12 years and is a bit weathered. Was hoping to use this kit instead of sanding the entire thing.

    NP

    It looks like a week will have passed since I cleaned my deck with Gemini cleaner and brightener before the weather cooperates to stain with TWP 100. Do I need to clean it again?
    • We will reply to your comment shortly
      TWP Stains · 09/02/2019
      No need unless longer than 2 weeks between prep and stain.

    I started using this today. This stuff is amazing. I have a 320 ft. fence. I didn't realize how time consuming this was going to be. I didn't take into account that after cleaning one side of the fence a
    a lot of the crap comes off ends up on the other side of the fence. Then vice versa. A lot of time going back and forth.
    Fence is new and about 9 months old.

    1. Is the brightener necessary? I used it and compared to a section that I didn't apply and didn't see any difference.

    2.After spraying the cleaner and stripping off whatever that stuff is the wood is now clean. If I go back and spray I'm still getting white liquid coming off the fence. I sprayed a section for 30 min. after it was clean and still get this. Is this normal?

    3. I'm thinking I may need to do clean/stain in sections. If I clean and stain a section and if any of the spray or a glop of whatever that stuff is lands on a stained part of the fence is it going to remove the stain?

      TWP Stains · 08/14/2019
      1. Yes, it neutralizes the cleaner.
      2. Yes.
      3. Best to clean and brighten all before moving on to any staining.

        tdub · 08/14/2019
        There were a few sections I didn't use the brightener. Does it pay to go back and spray it on now? Will not spraying the brightener affect the stain at all?
        After you mix the powder how long is it good for?
        • We will reply to your comment shortly
          TWP Stains · 08/15/2019
          Yes, brighten all. It could affect the stains appearance to not be even if you did not do all. The Brightener does not have a shelf life once mixed. The Cleaner needs to be used within a few hours of mixing.

    I purchased the Gemini cleaner and brightener product for prepping my sanded down cedar floor. I have a t&g vertical cedar wall that was coated with the same clear finish that was removed from the floor. I applied the cleaner to this wall to see if it would improve its appearance and the old clear coating came off and was able to sand down what remained. My question is the Gemini deck cleaner a cleaner or is it also capable of stripping? The old clear sealer is/was in good shape, and this product removed it. Old oil Cabot. My other concern is two years from now when its time for a redo will it clean or strip?

      It can remove old coatings if the old coating has deteriorated.

    I'm sanding a covered porch cedar deck and would like to apply TWP natural when done. Does the area need to be cleaned with the cleaner/brightened prior to restraining? Will the cleaner/brightened discoloration or darken the sanded down surface?

      Do I use the restore kit for this cleaning per instructions . Can the sealer be applied in high humidity conditions. Original deck floor is 20 years old over treated lumber subfloor with concrete below that. Wash water eventually drains down, but stays damp for a while.
      • We will reply to your comment shortly
        TWP Stains · 07/07/2019
        Yes, use the Gemini Restore Kit. Humidity is not an issue.

      TWP Stains · 07/07/2019
      Yes, it has to be prepped after the sanding. do not sand finer than 80 grit. It does not darken the wood.

      No, you need to pressure wash as well. No more than 1600 Psi.
