Mahogany's Beauty and Durability Makes it Ideal for Deck
Construction
A couple of years ago I had the chance to tour several newly
constructed Adirondack homes. One of the areas that particularly
stood out for me while touring these homes were the decks. All
used Mahogany lumber for both the decking and the railing
systems. The red color and the general beauty of the Mahogany
wood was unique to anything I had ever seen before in decking
material.
After completing my home tours I went out and researched
Mahogany further. First, there are several species and colors of
Mahogany, supplied by various countries around the world. Not
all are the same, however. It is the species known as American
Mahogany that has the rich red color that I had observed.
American Mahogany comes from the West Indies, Mexico, and
Central and South America. It is generally viewed as a harder
wood that is extremely durable and resistance to moisture and
insects. Also, because it is a hard wood it has a tendancy to
not split, twist or check. So be sure to ask about the species,
prior to buying Mahogany. Note however, Mahogany is a little
more expensive than pressure treated decking and railing
systems, however it is well worth it in terms of quality, looks
and durabilty.
Since discovering and researching Mahogany, I have built two
deck systems using this material. As I had indicated earlier, it
is a hard material that as a result, requires a little more
effort in its installation.
Fastening the Material
First, use stainless steel nails or screws on both the decking
and railing systems, as other types will not penetrate this
material very well. My preference was the stainless steel nails,
however pre-drilling holes is mandatory if not using a nail gun.
Even with stainless steel nails, they will bend trying to simply
nail them into the wood. I found that with the stainless steel
hex head screws that they chewed the wood going in and left
somewhat of a ragged finish on the surface of the wood.
Second, when installing the decking material, I found it
aesthetically most attractive to create a frame on the outside
perimeter of the deck surface using long Mahogany boards. Once
the outer frame is installed, the main Mahogany decking boards
can be simply installed within this outer framework. The result
is a cleaner line when viewed from a distance or standing on the
deck itself.
Regarding the Railing system, screws and bolts should be used
exclusively as the material use in this part of the deck is
typically thicker and requires more rigidity.
Painting, Staining or Sealing
Mahogany takes paint and stain well, however I have preferred to
apply a clear sealer. The clear sealer enables the natural red
color of the Mahogany to shine through, while still providing a
layer of protection from the environement. Typically I re-apply
the clear sealer every year to continue to preserve the color.
If you do not, the Mahogany will bleach out.
