Mahogany is a popular choice for decking because of its tight grain pattern and knot free appearance. It also does not tend to splinter as easily as other wood types. Although mahogany is naturally resistant to decay, it must occasionally be refinished to help protect and maintain the deck’s beauty.

Many deck stains are too heavily pigmented to penetrate into mahogany, leaving it vulnerable and risking stain failure. It is best to use a penetrating oil stain that will soak into the wood pores to give a mahogany deck the best protection possible.

There may be several good stain choices but the best stain for a mahogany deck is one that serves two purposes. One, to protect the deck from weather damage and secondly, to replace the wood’s natural oils. Replacing the wood’s own diminishing natural oils revitalizes and conditions the wood.

A penetrating oil based deck stain like Armstrong Clark the best stain for a mahogany deck that we have found. For reasons mentioned above, this stain is ideal for mahogany. The stain’s non-drying oils separate from the drying side of the stain. These conditioning oils replace the mahogany’s natural oils while the stain’s drying oils remain on the surface to lock in the conditioning oils and to lock out moisture.

This formula is also ideal for a mahogany deck because it comes in a mahogany color that really enhances the deck’s natural beauty. The semi-transparent formula still allows the wood grains to show through but adds just enough tone to the deck for a gorgeous finish. With conditioning oils and a durable barrier of protection, this truly is the best stain for a mahogany deck.

This user-friendly mahogany deck stain is the only oil based stain that can be applied in direct sunlight. Other stains may flash dry and cause and inconsistent finish. It is also a one or two coat finish depending on the absorption rate of the mahogany. If needed, a second coat can be applied wet on wet or wet on dry. It is a very versatile, easy to use stain that most any homeowner can apply over a weekend.

    I should have stated that he used oil based Varathane Polyurethane.

    Hello.I recently had a Batu (type of Mahogany) front porch floor installed on the north side of my house.  The contractor used oil based Varathane.  Was this a good choice?  Will it need to be reapplied eventually?  Thank you

      No, very bad idea. It will peel and attract mildew. You will have to sand it off to fix this.

        So, what should I have used on bare mahogany?And after I sand the Varathane off, what should I coat it with?How long do you think it'll take to peel off?And Finally, what is Varathane Ultimate Spar Urethane supposed to be used for?

          Use Defy Hardwood stain: https://www.opwdecks.com/defyhardwood.htm
          It will peel within a year. Never to be used on decks or porches, it will peel.

            Does it come in clear?  I don’t want to change the color. The first coat of the Varathane completely sunk into the wood. How deep do I have to sand?

              Clear coatings will not provide UV protection from graying. They must be tinted to do this.

                  It will still gray unless 100% enclosed on all sides.

                    I don’t care about greying that much.  But what causes the spar urethane to peel off the wood?

    I need to seal mahogany decking that’s in an Interior 4 season sunroom.  Not looking for a stain as I want to keep the natural mahogany look. Need a sealer that will not be slippery as I made that mistake once before at a different house.

    I have an exterior mahogany deck I will be sanding down to bare wood. The client wants a semi gloss look. It is mostly covered by a porch, but some areas do get hit with rain. What would be my best choice for a finish that will look nice and give a long lasting finish?

      Sorry, but we do not sell coatings that leave a gloss shine as that will lead to severe peeling and mildew on an exterior deck or porch.

    I recently had my 15 year old mahogany deck stained and had 9 1 inch thick boards replaced. The new wood was given a black spot treatment. The entire deck was then stained with two coats. 5 of the new boards blended in nicely. Four of them did not and have a reddish cast to them. Could I apply a 3rd coat of stain to the four boards to get them to blend in better?

    I have a mahogany deck (~15 years old). about 5 yrs ago I sanded and stained deck, most of deck has greyed except a couple areas where rugs/mats were covering so there's still some stain showing. in other areas there's some black stain/mold that were shaded & didn't get much sun. I intend to sand the deck, should I also use RAD prep afterwards? if so, should I use stripper with brightener or cleaner with brightener? I plan to use AC mahogany as the stain.

            So should I follow these steps?
            1) Power wash & let dry for a couple days
            2) Sand
            3) Strip & brighten & let dry for a couple days
            4) Apply stain & let dry for a couple days

                Hi - I’ve restained the deck and it looks great. I’ll probably go with the darker Mahogany color next time. It recently rained (a week after applying), how much should I expect water to bead up, if at all?

    Our current house came w/ a mahogany deck (20+/- yrs old) that was not well cared for. I've cleaned it w/ Dawn & Oxy-Clean; it's now mostly a salmon color, lustrous dark red when wet. I've tested several penetrating oils, but the wood will not take them up; they stay on the surface sticky and shiny. A previous owner likely applied a garden variety (i.e., non-penetrating) stain (there is "resiny" residue on the sides of the boards) which is preventing absorption; Note: the bottoms of the boards readily absorb the oil. Is there a product that will break down this incorrect stain and allow the wood to take up the penetrating oil? Thanks

    I have a mahogany deck that has been repaired over the years. I believe the last time it was Penofin was in 2007 Western Red Cedar. It's greyed out, but just testing with a power washer some of the boards came back to a beautiful brown. Will have it all power washed to see how consistent the brown is. Do you recommend sealing with a clear or stained penofin or can we let it just continue au naturel with occasional power washing?

    We have an attached porch at our lake house and the floor is mahogany. It appears it has never been treated. We want to just bring out the natural tone of the wood. What do you recommend?

    The day after I applied Armstrong Clark Mahogany Stain to mahogany boards I am using to build a platform in front of a door, we had a light rain and the drops beaded up. Would that indicate that a second coat is not needed? Can a second coat do any harm?

    I stained my mahogany deck last year with AC mahogany oil and absolutely loved it! So easy to work with, I don’t mind doing it again to achieve those results!
    I want to maintain that beauty so what do I need to use to prepare for another year in Connecticut? Clean and brighten before I put another coat on? Or just clean?
    Really appreciate this site!!! Thank you!

    I inherited a mahogany deck that is on the second story, underneath it is an office. Anyway when the deck was built it was not designed correctly to allow proper drainage. I treated the deck the first year I bought the house, but have noticed due to drainage issue some of the mahogany boards are rotting from the underside. What is the best way to salvage the mahogany? Should I pull all the boards up and put a sealer on the underside?

      A sealer will not stop the rotting from the bottom up. There is not a way to prevent this.

    Would this be ok for out door mohogany furniture? Or will it bleed off onto clothes?

      If applied and prepped correctly it will fully cure and not bleed.

    My mahogany deck was covered with Penofin oil about 3 years ago. It was washed with Jomax last week. Can it be stained with Armstrong Clark now or do I need to use the Restore a Deck Kit?
    thank you, Joan

      You will need to strip and brighten the wood if any Penofin remains. If not, you should be okay to stain as long as it is clean.

    I have a mahogany deck that hasn't been stained in roughly 8 to 9 years and is 14 years old in total. We are currently building a garage and are putting driftwood color doors. Could I clean and treat the deck with a driftwood stain? If so what do you recommend? Also, it's getting chilly in Connecticut, what is the lowest temperature where I could still stain it?

    Just installed Cambara Hardwood Decking on a front porch in early June (2018). The customer loves the grain and just wants to go with the AC clear. What's my prep to get this done? Can I do it now or should I wait a bit? Thanks!
    • We will reply to your comment shortly

      AC does not come in a clear and it must be a tinted stain if you want UV protection. The lightest tint is the AC in Amber for their hardwood colors. Wait another month or two and prep with the Restore A Deck Cleaner Kits.

    My mahogany floor in the screened sunroom has grayed in spots where water repeatedly rained in on. In other spots, the penofin held. What’s the best cleaner to get it all back to bare, and then the Armstrong Clark to protect it all? Gutters have been installed to stop water issues. Thank you
