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.

    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.

    I have 800 sq ft deck with 125 running feet of railing. Deck is new with 8-10 month drying. How many gallons of series 100 do I need? I read I should put one coat first, wait several months to put second coat. Is this correct?

    Hello, please add your dimensions into the calculator above to get the amount needed. Only one coat on new wood. See here for more info on this:

    I am staining an covered portion of my deck that was constructed with untreated wood. I would like this to have a little shine to the finish. Can I apply polyurethane to the top? If not do you have any suggestions?

    You cannot apply a polyurethane or any shiny coating over top of the TWP.

    When you say apply wet on wet, exactly what do you mean. If it is still wet when applying a 2nd coat, wont footprints affect the finish?

    Thanks

    I only see twp 101 in a sample not 100. I am looking for the most natural look for a cedar deck

    The 100 Clear is on the sample options. Clear will not provide UV protection/graying of the wood.

    For my deck I need a full kit and one 1/4 kit. For color uniformity, will both kits fit in one 5 gallon bucket when fully mixed with all parts? If not how do I mix the two kits together?

    Yes you will be able to mix both in the same bucket.

    I live in Minnesota. Installed a 1,200 sq ft PT pine fence mid last summer. Plan to stain (dark Oak)this spring. What prep should I do? Is TWP 100 allowed in MN? If yes, should I use 100 or 1500 series? I have a Graco airless sprayer. Is that overkill or should I use a pump sprayer? Back brushing recommended? Thanks !

    Prep first with the Gemini Restore Kit. Stain with two light coats of the TWP 100 Series. Lightly spray on the first coat then back brush or paid the second coat. Grace or pump should work.
