Calculator

These calculations will help you determine the square footage for the proper amount of stain and prepping supplies needed to refinish your deck or fence using TWP 100 or TWP 1500 Series.

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

Prepping Options

  • Gemini Restore Kit. This will be used for new, gray, dirty decks and for applying TWP over an intact older coating of TWP.
  • 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.

Deck Sq. Footage

Flooring Length x width =?

Railing Length x height =?

Steps Width x Depth x #of Steps =?

Add up all 3 for the Total Sq. footage.

Fence Sq. Footage

Length x height =?

Multiply x 2 for both sides = Total Sq. Footage

    bought a home in Maine with a deck that is in poor condition and looks like the pressure treated wood has had NO treatment at all over the 12 yrs it has been here. What products do we need to use on it?

    Prep with Gemini Restore Kit and light pressure washing. Stain with the 1500 Series.

    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.
