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 21,876 square feet of fence to stain. How much of the TWP 101 should I purchase to cover this area? If it helps, the panels are full cedar and the rail are pressure treated pine.

    Thx,

    I have a older cedar deck, I removed most of the old Behr stain(transparent),but there is still areas mostly verticle wood that has dark areas. The horizontal decking is clean. I dont want to use a power washer anymore because it is damaging the wood.
    Should I use the Gemini or the Restore stripper?

    You will nee the Restore Stripper but you will need to pressure wash after applying. Apply Restore Brightener when done.

    We will be painting our split rail fence. The length is 356 feet and the height is 4 feet. How much paint will we need for this project?

    Thank you,
    Cathy

    For both sides and two coats, about 15-25 gallons. These are hard to judge as they are not "solid" fencing and a lot of gaps between the boards. Hence the big difference. Start with 10-15 gallons and you will know the first few hours how much more you will need to buy.

    I want to try the deck revive product on my railings first and give the product one fill winter summer to see how it hold up. It can get as cold as -27 F in winter and as hot as 100 in summer, and I get a tremendous amount of sun.

    I want to coat the upper railing which is 2x6 and the lower railing which has ballusters. So I ould only be coating the railing uppers, not the ballusters. How many linear feet will the product cover 2 coats?

    Coverage is based on sq. feet, not linear feet. Please convert to sq. feet.

    I applied TWP stain to my deck floor last year, and an unexpected rain storm came through before the stain dried that resulted in some blotchy areas where there is little to no stain. Should I strip the floor completely and start anew ... or should I try to apply a maintenance coat over the existing? Thanks.

    Prep with the Gemini Kit and reapply.

    I am trying to determine what to do with my deck this year. I pressure washed last weekend and am thinking about sanding some areas as well. There are some areas that still have stain but most of it has peeled off. What are the recommended steps if I do sand the deck and what products would I need to strip/prep the deck before I stain? Is there a preferred method of applying the new stain that would work best?

    If you have old stain then remove it by pressure washing and the RAD Stripper we sell. If needed to remove some stubborn stain then sand after. Brighten all the wood when done with the RAD Brightener. We like stain pads for applying the TWP:

    I just finished building a cedar deck, about 1200 square feet. How long should I wait until i clean and seal the deck? What is your most natural looking stain? I don't want much tint added to the wood. Can you provide instructions along with quantities of your products I'll need for this project. Thanks in advance for your help.

    On a sperate note, my home is all cedar siding, can I use your products to clean and seal my siding? The house was built in 1998 and I see 5 gallon containers of Sikkens in the shed. Will your products completely strip the siding? Do i need to be careful of windows etc. Lots of questions here, thanks again.

    Please read this about new wood:
    http://www.twpstainhelp.com/prepping-new-wood-for-twp-stains/

    No tint means you will have no UV protection from graying. Lightest tint is the Honeytone color. Only one coat is required for new wood. About 6-9 gallons for 1200 sq. feet.

    As for the swing, you have to remove the Sikkens if you want to use the TWP. Sikkens has two versions of stain. One is strippable while the other is not. Not sure which version you have.

    I have over 1000 square feet of pressure treated wood ranging from 12-20 years old. I have used Sikkens in the past (probably 3 plus years ago). It did not hold up well. I have deck in full sun and some in complete shade. After pressure washing, it does not appear to have any stain quality left.

    This past week, prior to researching products available and your recommendation of a specific cleaner, I had pressure washed with TSP wood cleaner. Is this sufficient or do I need to go over all of it again with a different deck wash? (I hope you say it's sufficient).

    Which is the best choice for me -100 or 1500? I live in southern Illinois: humid summers and winters with snow and some ice.

    Thanks.

    All of the Sikkens has to be removed. If you still have some visibly on the wood then you will need to strip it off and brighten the wood, TWP cannot be applied on top. For IL you have to use the 1500 Series.

    I would like samples of 3 of your stains shipped ASAP since I would like to start staining the next weekend if possible. The stains I would like to try are: Cedartone, Honeytone and Pecan. My address is: Scott Retterbush, 4273 Whisperwood Circle, Valdosta, Georgia 31602.

    Which stain is the lightest color that will give me just a slighter darker stain look to the wood but still looks natural.

    Lastly, the review I read said they used the 5 gallon bucket to stain 800 square feet (2 coats) yet when I use your calculator to calculate how much I will need for 630 sqare feet it say I will need seven gallons. How much will I need?

    Lastly, how quick will I get my stain if I order this Monday and how is it shipped?

    Thanks,
    Scott

    You can order samples here:
    http://www.twpstain.com/stain-samples

    Use our calculator for the amount needed. Shipping takes about 2-3 days to Georgia via UPS.

    I am staining a pergola; how much stain do I need? Dimensions are: 13' x 13'

    Hello, we would need a total amount of wood in a sq. footage to give a proper answer. It could be anywhere for 2-5 gallons depending on how much wood you have.
