Mahogany Stair Treads
Mahogany has one of the most consistent grains out of any hardwood. It's generally hard to find a large knot, in one of these boards, even though every once in awhile you will find a small one. If you're looking for a stair tread that's reddish-brown, with consistent coloring and durable, Mahogany would be my first choice.
Honduran Mahogany almost doesn't make it into the
hardwood category and is one of the softer hardwoods. However it is
generally easy to work with and really doesn't need to be stained.
Gluing = Excellent, when I was a young man, I used mahogany to make a checkered board, that lasted for many years. To make the checkerboard, I needed to glue small pieces of mahogany (black squares) and ash (white squares) together, to create the playing board.
Sanding = Moderate, Mahogany is relatively easy to sand, however, it usually looks nice enough and won't require sanding, after it has been ran through a planer. Remember, you can usually purchase any hardwood, with a generally smooth surface.
Staining = Great, even though it has a nice reddish-brown look to it already, it can be stained if needed. If you're planning on staining mahogany, you could end up with an extremely dark wood, so be careful.
Nailing = Great, every once in a while you will need to pre-drill a hole, but for the most part, you should be able to use pneumatic nail guns, screws and finish nails, without any problems. Always pre-drill holes, if your nails or screws are starting to split the edges.
Wear And Tear = Great, even though Mahogany is one of the softer hardwoods, it still seems to provide homeowners with an excellent wearing stair tread. After awhile, there's a good chance that you will start to see wear patterns, running down the center of the stairway. If this is the case, you can install stair tread carpet mats, over the worn down areas or refinish the stairway.
Janka Hardness Scale = 800 However there are other varieties of Mahogany that go over 2,500. Red mahogany from Australia is 2,697.
