Q. Why are my boards splitting?
A. There could be several reasons for splitting. Check to see that you are lining up the long side of your nail with the grain of the wood. If you nail against the grain your nail is acting as a wedge to split the wood. If your nail is longer than 1 1/2″, you may want to drill a small pilot hole to help ease the nail into the board. If you find that the pilot hole is not large enough, widen it to the thickness at just below the center of the shank and try again.
