This calculator will help you determine the proper amount of stain and prepping supplies needed to refinish your deck using TWP 100 or TWP 1500 Series.

 

This calculator is intended to provide you with an approximate estimate only. Material requirements may vary according to application method, surface condition and weather conditions.

 

You will get two prepping results. You need one, not both options:

  • First will offer the Gemini Restore Kit. This will be used for new, gray, dirty decks and for applying TWP over an intact older coating of TWP.
  • Second is the Restore-A-Deck Stripper and Restore-A-Deck Brightener. This is used for removing old coatings of stain. Use this if you are switching from a different brand to TWP or if you have a neglected coating of TWP that has failed unevenly.

 

If you have questions as to which to use, please ask below.

    We just need TWP for the floor of the porch. Railings are painted white. We used your product almost 8 years ago and it is now ready for a new coat. Can't find it locally for sale. Our old gallon can says TWP101 Cedartone Natural. Is that still available and how much do I need for the size
    listed below?
    Our covered front porch length is 33 feet and 2.5 inches
    Our covered front porch width is 7feet and 9 inches

    Wondering what the best color is for tigerwood deck. Would like as little color additive as possible but still have UV protection.

    Look at the Honeytone

    I have a dock (not deck) that I am refinishing. I took apart an old pine wood deck, flipped the 5 1/2 inch X 4 feet boards, had them planed and am now ready to stain/seal. I live on a small no wake lake in Central Wisconsin. What is your recommendation?

    Use the 100 Series.

    Last year in June I applied TWP100 redwood stain and my wife doesn't like the color. This was the 1st coat on my 1 year old deck. It's time to clean and stain again and she wants to change to a darker brown color. Any ideas?

    Use the Restore A Deck stripper and pressure washing for the prep. Brighten the wood when done. Stain with the Dark Oak.

    I have completely sanded the old stain on my covered screen porch cedar deck built in 2008. Do I need to use both bottles from the Gemini Restore kit? Also I don't have a sprayer, will I still get good results.

    Yes you should both. You can get a pump sprayer for $30 at a local hardware store. Much easier then scrubbing it on.

    i had a new cedar deck in 2013. I made the mistake of putting Sherwin Williams Deckscape sealer/stain on it after waiting 12 months and following powerwashing. The SW product started peeling off during the winter following its application in August 2014. So, the deck was just powerwashed again this week to remove the SW stain/sealer and most, but not all the stain came off. The only places it remains adhered to the deck is on the knots in the cedar.
    Question is, should I use a wood prep product before applying your oil based stain/sealer? If so, which one? How long should I wait to apply sealer/stain after wood prep, if needed? Is TWP 1500 the best product for cedar deck stain/sealing and if yes, should I do 2 coats or 1 coat? And, lastly, how often (1 year, 2 years, etc) will I need to re-apply the TWP product to maximize protection of the deck?

    Yes try the Gemini Restore Kit for the prep. Apply 2 light coats of the TWP 1500 but apply wet on wet method. Reapply every 2 years.

    I have a wood deck that has not been treated for several years and is in need of a good treatment. What type of Restore application do you recommend for cleaning the surface? I am not sure what type of wood was used for the deck.

    I do plan to use the TWP Dark Oak stain (1503) on the deck.

    Thank you.

    Does it have an old stain or just dirty?

    I have a deck that was stained with a cedar oil based stain many years ago. I ordered the Gemini kit along with the TWP 100 cape cod gray. Can I use the Gemini kit or should I return it for the Restore-A Decj stripper and brightener? Thanks

    The Gemini Kit is not a stripper but it "may" remove a very old semi-transparent oil based stain if it has been many years. Hard to say yes or no if it will do the proper prep.

    I found your TWP 100 product on the restore a deck website, is your Gemini cleaner and brightener and stripper the same, or better? You price on the TWP is cheaper so I was going to order from you.

    They are the same products.

    Bill C:
    Our deck was painted gray and we wanted to return to the natural wood look. It is now sanded down to the wood, pressure treated pine. Does it need any additional prepping? The majority of the deck is in good shape, one or two planks have some splitting that is at worst, 1/8" deep.

    Use the Gemini Restore Kit for the final prep.
