This is my latest of several AirStone projects, I’ve gotten a number of compliments on it. Thanks! — Matt
AirStone tip: Like natural stone, AirStone will absorb food splatters and/or grease. We recommend using a sealer when using AirStone as a kitchen backsplash, or an outdoor kitchen. Use a high-quality brand for concrete, masonry, or porous stone. Follow the manufacturer's directions and reapply as instructed (in general, it's best to apply a THIN coat and let it dry thoroughly before applying another coat).
