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.

    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?

      1. Yes, it neutralizes the cleaner.
      2. Yes.
      3. Best to clean and brighten all before moving on to any staining.

        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?

          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.

        Yes, use the Gemini Restore Kit. Humidity is not an issue.

      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.

    If the product is applied to a porch that is in great shape with TWP on it would it affect it at all? Most of my Ipe porch is in great shape with TWP 116 but the stairs are in bad shape. I don't see that the porch needs cleaning only the stairs but when I apply and rinse it will end up on the porch just curious if the product has any affect on wood that has a very good condition coat of TWP on it?

      This product is used for prepping when reapplying. If some of it gets on your porch, it may "Clean" or lighten some of the TWP that is on the porch.

    I used TWP 1500 Redwood Stain 5 years ago and ready to re-stain again using the same stain. Do I need to use the cleaner and brightener again? Thanks!

    Is it a problem if it were to rain after I cleaned & brighten my deck?

    No. Just make sure it dries for 24-48 hours after a rain before applying the TWP.

    Hello,
    I have a pergola made of thick, rough-sawn wood. Do I need to prep this type of wood or is it porous enough to begin staining?

    You do not have to prep rough sawn wood as long as it is clean and dry.

    Does the restore kit have to be applied when the deck is dry (and if so, how long does it have to dry for)? Or can it be applied, for example, right after a rain shower has occurred?

    You can do the prep with the wood damp.

    My fence is about a year old and I've already pressure washed it. There are still a few spots that are a little green or discolored. My neighbor used a liquid spray cleaner and just hosed it off. Do you think that would be adequate for using the TSP cleaner? I plan to follow up with TSP 100. I live in the Seattle area.

    It would be best to prep with the Gemini Restore Kit for this. TSP is not the proper way.

    will the wood cleaner or brightener affect concrete pavers or stone? i.e do I need to cover the patio before using the products on a nearby deck?

    No they do not harm/effect concrete or pavers. It may clean them some though.

    Planning to use Gemini restore kit on cedar clapboards previously stained (5 years ago) with TWP101. Water supply to the house is via drilled well and is within 15' of the house. Is Gemini system safe to use in this situation?

    Thanks,
    Rob

    Yes it is fine.
