backsplash behind kitchen sink
i have an area behind the kitchen sink which is below the window it is only 9 inches high is painted. i really like the paint color but it is constantly getting spotted from washing up in the sink. . could i seal this painted surface.? i thought about using a polyurethane floor sealer. would this be okay. and could the area be repainted in a few years if i wanted to change the color? i have granite countertops and did not want to extend the surface for a backsplash but now i need to do something.
