The gas grill splatter Mat is specially designed for use with gas grills. This 48 x 30" Engineered Mat protects brick, stone, wood & composited decking surfaces from the spills & unsightly staining commonly associated with outdoor grilling. This unique mat's rectangular shape, size & color is ideal for every gas grill. The gas grill splatter Mat is light weight, heat & weather resistant, yet durable for years of outdoor use & protection. Our splatter Mat is designed to capture liquids & grease residue created by gas grills. The Splatter Mat has been designed not to damage composite decking as it contains no rubber backing. Easy to clean - mild sopa & water - hose off & hang to dry. Use of The Splatter Mat requires a minimum of 24" Clearance between the gas grill heat source & the mat. This mat is not designed to be used in extreme heat conditions for extended periods of time. As with any object resting in one place for extended periods, weather & exposed conditions of the area protected by "the gas grill splatter Mat" Will differ from the surrounding area not protected by the Mat. Therefore, you may notice differences in appearance between the area directly under "the gas grill splatter Mat" & surrounding, unprotected areas upon removal of the Mat. "The gas grill splatter Mat" Does not allow water penetration through it. On occasion, rain or a misdirected sprinkler system will force water between the mat & the outdoor surface causing a water mark if the mat is not removed to allow the area to dry.
