Calculator

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.

      Just enter into the calculator the info for the railing height as your fence height and the railing length for your fence length. After it shows the amount, multiply products needed by 2 if doing both sides of fence.

    Hi.  We have a 10-year-old deck, in good condition, was sealed appx 5 years ago, and power washed twice since.  There is currently no product on it.  Do we need either of these prepping options? Neither really seems to apply.  We are power washing and sanding again prior to application of Semi Solid.

    If I'm staining my 432 sq. ft. deck for the first time (one year old pressure treated wood), will 3 gallons suffice or should I get 5 gallons? I believe I read that I should use just one coat for the first application vs. wet on wet. Also, would you recommend 100 Series or 1500 Series? I plan to use the Gemini restore a deck kit before stain application.

      For 1 coat, 3 gallons should be enough. Which series to use depends on where you live?

    Is twp 1515 a good product to use on an older log home. The logs in this home are yellow pine and about 30 years old. We have cleaned and stripped the old finish.

      Use the Gemini prep while pressure washing for the best results.

    Are there any plans to create a grey color in the 1500 series? I live in Ohio and cannot use the 100 series. I would love to use TWP, but I am going to be forced to use a different brand.

    New cedar deck last October. It has aged so I’m ready for the Gemini restore kit and my stain. I thought I read somewhere on this site that for the first application I only want one coat. Is that correct?

    I just finished a 28x9 PT deck with 6" deck boards.  When would you advise I stain the deck as I understand new PT needs to dry out first?  How many gallons should I order?  Thank you.

    Hello, the calculator is saying I need two gallons of stain with the following statement:
    (assuming 2 coats wet on wet. Use 2/3 amount for 1 coat)

    Do I do 2/3 of 2 gallons for the first coat i.e. 1.34 gallons first coat?

    The customer service on this place is outstanding, I've never had a question I couldn't answer myself with the information provided right on the page itself. The patience shown by the company while answering most of these questions is unprecedented. Good job guys.

    How many gallons of stain (wet on wet) will I need to cover approximately 450 s/f of deck using a brush.  This includes an estimate for bench seating and a 4x6 landing area which I couldn’t input to your calculator. Thanks

    How do you know if you need two coats? My deck is at least 11 years old and raw sun bleached pressure treated pine. Is it typical to need two coats?

    Our fence is approximately 183 linear feet long, 5 feet tall. It is not a typical fence so we are trying to figure out how much stain to purchase to stain both sides.

      15-20 gallons for two coats applied wet on wet.

    • We will reply to your comment shortly
      TWP Stains · 08/14/2022
      It is measured in sq. feet not lineal. Coverage can range between 150-250 sq feet per gallon.
