I’ve sanded, pressure washed and stained many Mahogany decks in this area.
If left untreated they weather, and eventually crack and split just like most other woods.
They generally loose that beautiful color and start fading within the first 2-3 months if not treated with oil such as Australian timber or other similar product immediately.
I’ve been searching for a product that lasts more than 1 year but have not found anything that keeps it natural.
I have switched to Penofin marine oil and it does last longer than the recommended oil for hardwood but still not much over 1 year.
Unless it is a covered porch I would never build or recommend a mahogany deck in New England.
I built my own out of Cedar and treated it with Penofin oil on all sides before installing it, and after one year it looks brand new.
One of the biggest killers of decks is lawn furniture and using a shovel with a metal blade to remove snow. Both wear or scrape the finish off and once that’s done water has a way into the pores of the wood and eventually works its way outward.
I always suggest people put protective pads on the feet of their furniture and buy a cheap plastic Wal-Mart shoved for clearing the snow off any treated surface. You wouldn’t use a metal scraper to clear the snow off your car, same thing applies.
Oh on the original post of 40 feet from water. I’ve done all the docks at Southdown shores which are over the water. It makes no difference as long as the surface has proper time to dry out before you apply the product. Call Brian and ask how the product is holding up down there. In that application with the level of traffic they needed to be redone every other year but do not. You know how it works with associations, they wait until it absolutely needs it before acting in most cases. Which is too bad because they usually wind up paying more in the end for repairs.
