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.

    Hi

    I have 352 sqft of pine shed outside walls

    3 years ago did full strip, restore and 2 coats of wet on wet of 1500, used about 5 gallons

    Want to do a maintenance coat now, restore and if it can absorb 2 coats of wet on wet

    Should I expect to use the same amount of product as 3 years ago?

    Yes you will need a full reapplication after 3 years. Prep with the Gemini Restore kit as well.

    We have 230 feet of 6 foot cedar fence and 10 feet of 4 foot cedar fence that we are planning on staining with TWP 1500. Is 15 gallons the correct estimate for the amount of stain needed to stain both sides of the fence?

    230 linear feet? If that is what you have then the total sq. footage is about 2900 sq. feet for both sides. That means you will need 25-30 gallons for two coats of TWP.

    I live in Chicago and I have new pressure treated deck, It was built last September 2015. I would like to keep the wood a light color but was to try and keep the maintenance low. The house has tan siding what stain should I use and what color do you suggest. Thanks

    Lightest tint in the TWP 1500 Series is the Honeytone. Prep first with the Gemini Restore Kit.

    My deck is pressure treated pine and has been in place for 2 years i have only used a linseed oil treatment so far, which TWP stain should i use for treatment, also, the deck is approximately 700 square feet with 80 feet of hand rail and splindles

    What state do you live in? Either the 100 or 1500 Series based on your state laws. Prep first with the Gemini Restore Kit. You will need roughly 8 gallons for the 2 coats.

    My deck is new, was coated with a transparent water based sealer (Thompson) a year ago. Your calculator says it is 400 Square feet.In the fall it was washed with a bleach/water solution and is pristine except for exposure since then to the weather in Prescott,AZ.It is red wood (first cut). I intend to use the redwood semi-transparent stain/sealer - 2 coats. What kind of cleaner would I use taking into consideration that is has been exposed for seven months.Do you have local distributors?

    Best to prep with the Gemini Restore Kit. We are an online dealer and can ship this to you.

    Can we use this product on untreated wood siding? I love it on my cedar shakes.

    Yes it can work on all exterior untreated wood as long as there is not a previous coating of a different brand.
