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.

    Looking to do the cedar siding in the 1500 series. It has previous stain, but wood is in great condition. I want a mostly transparent stain. I'm thinking Natural or Honey. What do you guys recommend for color and preparation?

    Best to apply the Restore A Deck Stripper and pressure wash off the old stain. Use the Restore A Deck Brightener when done. Please read this about colors:

    Todd Gill:
    I have a fence I am looking to stain with the 1500. The fence length is a shared fence so I only have to stain one side
    and it is 85ft on both sides of the property and the width is 35 feet and I would have to paint both sides of that. How much stain would you recommend me purchasing?

    Summary
    85 length on each side must stain one side
    35 width (total) and both sides must be painted

    Please give us a total sq. footage. Thanks!

    How much do you recommend for a 10' X 30' deck?[/quote]
    Butch, did you use the calculator? It will give you amount.[/quote]
    I did, however I was concerned that it was requiring too much because this is my first application.
    For newer wood and only once coat you would use 2/3 the amount that the calculator suggested.
