That means that stain won t go so dark in the end grain. Notice that on the final sanding, I use the same grit again, only I switch to garnet paper and sand by hand, with the grain, instead of with a power sander. You can spray waterborne coatings from any type of gun that has stainless steel or plastic fluid passages. Waterborne coatings may rust or pit carbon steel and aluminum. If you use a standard gun, simply change the fluid tip to a stainless steel tip.
Stain is anything that adds color to raw wood.
It can be made from pigments, dyes, or anything else that imparts color to wood, even such unorthodox materials as coffee, tea, and berries. Chemical stains are chemicals that react with something already in the wood to create colors. But no matter what you use as the coloring agent, if it colors wood, it is a stain.
