A butt joint is when you join any piece of wood together
with a flat surface or 90° angle. The picture below represents two
individual pieces of wood that will be glued together, in order to form
one piece.

There are other methods that work better, providing you
with a stronger joint, like tongue and groove, mortise and tenon and
dovetails. A butt joint is used for creating tabletops, cabinet doors,
risers and treads.
If you're really looking for a strong woodworking joint, I recommend
using another method. Even though it's rare to have a butt joint fall
apart, it does happen every once in awhile.
If you're going to use this method on the exterior of a building, make
sure that you use exterior glue, for additional wood joint
reinforcement. If you're going to purchase building materials that have
been glued together, make sure that you verify that the products can be
used on outside of the building.
Sometimes all it takes is a little bit of moisture or heat to separate
any woodworking joints.
I was recently in one of our local home improvement centers, purchasing
an 18 inch wide by 36 inch long piece of pine, that was created, using 2
inch strips and gluing them together. I asked one of the store
representatives for more information about the product and he told us
that you couldn't use it outside.
They had already had problems with this product.
You can apply this information to any furniture, handrail components and
other stair parts, also.
