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.

    I have a 400 sqft deck no stairs and the railing has metal balusters so no need to stain them.

    The deck was installed at the beginning of April and i want to stain it before the winter is here

    This is on the second floor and I want to stain both the upper and lower part of the deck as well as the posts.

    Can you let me know which products and quantities should i buy for this job?

    thks

    If you are doing upper and lowers you will need to double the sq. footage and then add on extra for the framing and posts. Total sq. footage could be in the 900-1000 sq. foot range. Prep first with the Gemini Restore Kit and you will need about 6-7 gallons for the one coat. Use the TWP 100 or 1500 Series depending on what your state allows.

    If applying wet on wet, is it possible to determine if over applying? How would one go about applying 2/3 and 1/3 if using a pad application?

    You want all the stain to soak into the wood grain. Over applying will result in a shiny and stick finish. You apply as much as the wood allows. The first coat on older wood should soak right into the wood grain and most likely will be a little uneven in appearance. The second/final coat will spread twice as far as the first coat and will give a nice rich and even appearance.

    I have a deck that is around 700sq ft. It was built about 1 year ago. What should I use to clean it and how much should I buy? Do I need to put on more than 1 coat of 1500 stain? How much 1500 is needed for the square footage. Also I haven't read anything about a sealant. Is sealant needed in addition to applying the 1500?

    The TWP is a sealer and a stain. You will need to prep with the Gemini Restore Kit. Just one is needed. For 700 sq. feet you will need about 6-7 gallon for two coats applied wet on wet.

    I have a 16 x 32 older pressure treated deck that I have sanded first with 35 grit and then with 60 grit to completely remove a peeling solid white coating. I am now down to bear wood. This deck is in full sun most of the day/ I am located in central connecticut. I would like a semi transparent stain. WHat would you suggest and how long should I expect it to last.
    1 year? 2 years?

    Use the TWP 1500 Series. Last about 2 years for most scenarios.

    Please explain what "2 coats wet on wet" refers to in regards to estimating the stain application.

    See this about how to apply wet on wet application:

    http://www.twpstainhelp.com/twp-stain-wet-on-wet-application/

    The calculator takes in account that you are applying two coats with the wet on wet application method that is needed. New wood only needs one coat, so you would use about 2/3 the amount that the calculator states.

    2 Questions for you...
    I have a steel roof with wood perlins and beams that also need to be stained. How should I account for those when buying the stain and prepping supplies?
    I want to stain the horizontal surface dark and the vertical surfaces white. What do you suggest I use for the white columns?
    Thanks so much for your advice!!

    You would want a solid color deck stain for the vertical white columns. TWP does not come in a solid stain so it will have to be a different brand. For the TWP (horizontals), use the calculator for amount needed. Maybe Dark Oak color since you want it to be dark.

    Just purchased cedar from amish sawmill, completely dried. Using it to wrap porch beams. Should We stain first or put up and wait til spring? In Michigan most of it will be under roof and not exposed

    Put it up and wait until Spring. Prep first as well.

    Can TWP 1500 be applied over sikkens Cetol SRD

    No it cannot. The Sikkens would have to be stripped first.
