    Hi, I’ve stripped the spindles of my deck to bare wood (that was a lot of work) and I’m staining them in TWP dar oak. I’ve followed all directions but it looks so ugly, it looks like there is dirt on the spindles trapped under the stain. It looks worse than before, and before they had an ugly Superdeck stain. What could be wrong ? Please see pictures of the spindles before and after.
     I’ve also used this same TWP stain in dark oak on an outdoor wood table and that came out nice. Please help! Thank you.

      That is your wood grain  of your spindles being enhanced under the TWP Dark Oak. TWP enhances the wood so the final color is based on the TWP color you choose and the actual wood itself. Internally, your wood has dark discolorations.

    Hi. I am about to restain an old P.T. deck (ACQ, not CCA) previously stained with TWP. The color I used last (which at over 3 years is virtually all gone) was 1516 Rustic. This came out way too "red" as what I am shooting for is the color of mahogany. I was thinking possibly mixing 2:1 either dark walnut or dark oak with the rustic to achieve the color I'm looking for - what do you think? I managed to just get by with 2 gals last time, but am planning a small extension so I will purchase 3 gals in total this time. Thanks for any insight you can give me!Charlie

      You can mix colors but as to what you want to achieve color wise, you can only test the ratios to see how it will look on your wood.

    Hi, we are about to restain our large cedar fence with TWP 1500, which we used to stain it 4 years ago after the wood had aged about 18 months. We’re really happy with how the stain has held up. The wood is in largely in good condition, except for some top pieces where snow and rain collect. We live in an area with intense sun and wind.
    1. Do we need to power wash it?2. Do we need to clean it with the Gemini kit?3. How many coats would you recommend for the stain?4. How many gallons would you recommend for this restaining of the fence? It’s 147’ long x 5’6” high including about 1.5” x 1.5” wood (baluster) spindles and small crosspieces at the top that involves a lot of in-and-out painting.  In addition, the vertical fence boards are separated so must be stained on the sides as well.
    Thank you!!

        Thank you! The fence is roughly 800 sf. x 2 sides for a total of ~1,600 sf. Again, this is a re-stain after 4 years; don’t know if that means we’ll need less product than for the initial stain. We were advised to purchase 15 gallons the first time but had a lot left over. Also, how many Gemini clean/brighten kits would you advise for this square footage?
        Thanks again. Your customer service is really awesome.

          10-15 gallons for two coats applied wet one wet and 2 of the Gemini Kits.

    Where can I get stain mixed/ spun?  Do you know?

      Just go to your local paint store and get a drill mixer for paint. Attach that to any drill and mix. Very simple.

    I have a 4-5 year old redwood deck that was originally stained with Armstrong deck stain but I would like to re-stain with TWP 1511 California Redwood.  What prep work is necessary before using the 1511?

    The deck is 20+ years old. It was last stained with TWP in 2015. (We bought the house in 2019.)
    1. Should I use pressure-treated wood for the deck boards if I intend to use TWP semi-transparent?2. What manner of surface prep should I do since I'm restaining over a TWP stain?

    Do you recommend TWP 1500 or Semi-Solid for the following situation?
    1. ~1500 SF Pressure treated pine deck in Central Texas, most of which is 15 months old and grey, but ~6-7 boards were replaced 6 months ago and are still yellowish.2.nothing has every been applied to the wood, but it has been cleaned with a  wood brightener and brush3. The deck is off the back of the house, and a small chlorine pool is off to one side. Large live oak trees grow over most of the deck, so pollen sticks and leaves drop heavily 2 times a year. Light traffic.4. Of primary concern is longevity of application (protection), natural appearance, and ease of maintenance.5. Seeking medium to dark brown color with no orange or pink/red hues.  Color advice? Thanks for the advice.

    Ny deck is partly exposed (for 20 years) and partly covered (for 30 years).  The exposed portion especially is heavily blackened in places.  Can I pressure wash it and then stain it, or do I need somethin else to remove the black stuff before I stain it?  (I have pressure washed a portion of the uncovered part and that cleaned off maybe 75% of the black stuff).

      We would need to see some pictures to give proper advice on the prep. You can post them here.

    Newly milled and kiln dried, rough cut pine, never been stained. Pool house/outdoor kitchen under roof but not enclosed - 4"x12" beams and 2'"x12" exposed rafters. I'd like a dark walnut color for the beams and rafters, and would like as much grain to be visible as possible. Above the rafters will be new wood, 1"x6",  tongue and groove, clear pine, smooth surfaces never been stained. I'd like to use a lighter shade on this area, something like a honey oak. Could you offer suggestions on best products?

    Does the 1500 series contain paraffin? If not, could I add it myself without harming the product? 
    • We will reply to your comment shortly
      TWP Stains · 05/09/2021
      It is not paraffin based and do not add it. There would be zero benefit and could create curing issues.

    How much wood grain shows through on the 1500 black walnut vs a similar color of the semi-solid pro series?  I have an older deck that has not been maintained well.  I'd like hide some of the cracking but would also like some grain to show so it doesn't look like it is painted. what is the best option? I'm in Virginia beach, deck gets mostly sun, however, areas close to the house are completely shaded.

      Semi-solid colors will always show less wood grain compare to any of the semi-transparent colors. Either would work for you but you will get better UV protection with semi-solid colors. Maybe try samples to see what you like better? https://www.twpstain.com/stain-samples

    Hi, 5 yr old, covered deck, pressure treated (I'm assuming pine?), never treated, but cleaned every year and looks like new since very little exposure to sun or rain. I want a light color but at least some protection from UV for small outdoor section that will be the same color. Also want water base, not oil. Recommendation?

    Deck is 8 years old. Pressure treated and stained with sherwin Williams semi-transparent stain. Wood is in good condition. Needs to be re-stained. Do I need to strip it before I use TWP or will the cleaner/brightener be enough? ThanksLori MiserLoribluemiser@gmail.com

    We live 100 ft from the Pacific Ocean and our patio furniture is mostly teak and our doors are alder and line that was previously stained a varnished with marine spar. Most of the varnish has peeled off and we would like to apply twp 1500 to all furniture and doors thinking we could save ourselves the stripping process and just apply TWP as needed without all the fuss. Is this a good idea?  Is TWP alone without varnish a good protectant against the constant ocean abuse?  Is is advised to apply a varnish over the twp? My wife would like to apply a wax. Is this a bad idea?  Any advice is recommended. Thanks

      No, you cannot apply TWP over the old coating. It must be removed 100% first. You also cannot top coat TWP with a varnish or any type of coating.

    I overbought and have about half of a 5 gallon bucket of TWP1500 left.  The seal on the bucket does not seem airtight.  Do you have any recommendations for keeping this leftover stain for next season?  
    • We will reply to your comment shortly
      TWP Stains · 04/21/2021
      Buy some empty gallon containers and store the stain in them for airtight storage.

    Do you sell smaller amounts of product for restoration/refinishing of redwood outdoor furniture?
    I'd like to remove varnish applied by previous owners, and then recover with TWP. I only need enough to cover 2 loveseats and an armchair.

      TWP Stains · 04/06/2021
      Gallons are the smallest size. You would have to sand off the varnish.

    My entire deck and railing is stained with 1500 Black Walnut. It needs redone this spring and I'd like to try a semi solid this time. What color semi will match closest and is there a way to just buy a sample rather than a 55 dollar gallon in case the color isn't right?
    • We will reply to your comment shortly
      TWP Stains · 03/31/2021
      We are not offering samples of the semi-solid colors per the website and sample order page. Closest would be the Charcoal color but is not exact.
