- 1). Sand the tiles of your backsplash with a vibrating sander and medium-grit aluminum oxide sandpaper. Go over it slowly, pressing the sandpaper firmly to the surface to dull the shine of the surface.
- 2). Spread oil primer over the whole surface, including the grout, using a paintbrush. Let the primer set for 24 hours.
- 3). Paint the tile with oil paint. Paint the whole backsplash a solid color, grout and all, or paint just the tiles and let the white primer separate them on the grout lines. If you're artistically inclined, you can paint a mural on the surface.
- 4). Let the oil paint set for at least 24 hours.
- 5). Apply oil-based polyurethane over the whole backsplash, grout lines and all, with a brush. Brush it on in a smooth, thin layer, avoiding bubbles and streaks.
- 6). Let the polyurethane dry for 24 hours. Sand it by hand with fine sandpaper, buffing it just enough to dull the shine so the next layer will stick.
- 7). Brush on a second layer of polyurethane in the same manner as the first. Let it set, hand-sand it and apply a third layer. Let the third layer dry clear.
