Remove any excess roots around the bottom of the stump by either ripping them out with gloved hands or using small saws to remove hardier roots. You might also want to turn the stump on its side and hit it with your hose to remove dirt, debris and any lurking insects.
Sand the top of a tree stump with sandpaper or a sand sponge until it's smooth and even. Wipe off any wood shavings with a clean, dry towel.
Apply a varnish to the top of the stump to give it a glazed look if desired. Apply one coat of varnish in even strokes and allow it to dry for about 20 minutes before applying two more coats of the product. Allow the second coat to dry fully before applying the third coat, and remember to apply the varnish in a well-ventilated area to avoid excess fume inhalation, as varnish features a very strong odor.
Paint the sides of the tree stump, if desired, in one color, multiple colors or in various patterns and designs. You can also opt to leave the stump as is for a rustic furniture piece.
