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.

    Can I get TWP 1500 in a semitransparent reddish tone? I’m doing a deck with an old redwood stain color on it.

    It comes in a Redwood color and a Rustic Color that are reddish: https://www.twpstain.com/twp-1500-series-5-gallon

    To use the TWP, you will need to prep by removing the prior stain.

    Hi,
    We have 600 running feet of three-rail solid-picketed pine fence, 6 foot tall. It surrounds our group home on three sides. A band of volunteers is coming to stain the side with the rails this go-round. The fence is older, in fair shape, pressure-washed and thirsty. Will be applied by roller and brush. How much 100 Series do you recommend we order? Many thanks.

    600 x 6 x 2 (both sides) = 7200 Sq. feet. For the two coats applied wet on wet you will need about 60-70 gallons.

    Our deck is pressure treated built in 1985 and located in a wooded north exposure. Get about 1 hour of direct sun per day. The last time I stained it was over ten years ago. I pressure wash it about every 2 - 3 years with a 2800 PSI 7.5HP unit. Power Washed 3 days ago and the deck still looks great. Thinking about twp101, it's bright. Deck surface 400 sf, wood walkway 130sf, and built in benches 60 sf. Last time I sealed the deck was ten years ago and I rolled it. All stain and sealer seems to be going after 3 - 4 power washings during that time. Happy with brightness and cleanliness. Do I still need additional prep? Was thinking 1 5 gallon can. Thoughts?

    Sound like your prep is good. Make sure it is clean and all old coatings are removed. For two coats, you will need about 5-6 gallons.

    Hi I have a red cedar fence which was stained with 1500 3 years ago. I want to do a maintenace coat the stain is still holding up good. Do I still need to use the cleaner and brightener before I re stain? Or is cleaner good enough

    Cleaner for sure, Brightener can be used as well.

    I have a western red cedar fence that is unfinished and about 18 months old. It is six feet tall and 185 linear feet. Id like to use TWP 100 semi-transparent. How much should I order?

    For two coats applied wet on wet to both sides of the fence, you will need about 20-22 gallons. make sure to prep the wood first with the Gemini Restore Kits.

    We live in Iowa. Green treated deck, 200 sq. ft. in full sun. Stripped all old finish off and used Woodsman Brightner. We would like to stain it with the Cape Cod color. What is your advice about how to proceed?

    All of the old stain does need to be removed first. Woodsman brightener is not a stain stripper. Did all of the old stain come off? If so, you should be good to stain.

    I treated a new 12X24 treated wood deck with 5gals of 1500 in natural (1530) a little over 3 yr ago. I live in Virginia and need to retreat. Would 1500 work and will I need any pre-treatment? I plan to pressure wash it first.

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