End grain is the terminating point of pores in the wood, an open doorway for moisture. End grain sealer is a specially formulated product that enters the wood through the pores where it hardens to form a barrier against moisture osmosis. Take a few minutes to protect your wood by applying wood grain sealer. It's easy to do with a brush, and pays off in the long run by making the lumber more stable and less prone to warping.

Tips and warnings
- For large projects such as lumber in decking, bunks or units, you can apply end grain sealer with any air or airless spray gun using a large bore paint tip on the spray gun. Liberally coat any and all end grain.
- Don't worry if the end grain sealer overlaps the face grain. It will do no harm. This is actually recommended on large units of lumber.
