Demiwise 48x36in Grill Mat — Heavy-Duty Fireproof & Waterproof Deck and Patio Protector

Demiwise 48x36in Grill Mat is a heavy-duty, fireproof and waterproof barrier that protects decks, patios, and lawns from grease, ash, and scorching from outdoor grills and fire pits.

This extra-large grill mat is built from high-temperature fiberglass with silicone coatings on both sides to resist oil, water and heat while remaining thin, flexible and easy to store. Designed to fit most grills, smokers, griddles and charcoal setups, the mat creates a stain- and scorch-resistant surface under your cooking area so you can grill with confidence without worrying about ruined decking or pavers.

How does the Demiwise mat prevent stains and heat damage?

The mat uses a dense fiberglass core coated with high-temperature silicone that blocks grease, marinade spills and hot ash. Its non-porous surface prevents liquids from penetrating into wood or stone, and the fiberglass withstands very high temperatures to reduce the chance of scorching.

• Silicone coating repels oil and water for easy cleanup
• Fiberglass core resists temperatures far above typical grill heat
• Non-absorbent surface stops stains on wood, composite and stone
• Thin profile lays flat under most grills without rocking

Will this size work with my grill, smoker or fire pit?

The 48 x 36 inch size fits many standard grills and compact smokers; Demiwise also offers larger 65x48 and 76x48 options for bigger setups. The rectangular shape covers the common footprint of gas grills, charcoal grills, griddles and small fire pits while leaving clearance for ventilation and wheels.

• 48x36 inches suits medium grills and small smokers
• Larger sizes available for oversized or multi-burner units
• Flexible edges allow placement around wheels and legs
• Thin, foldable design adapts to uneven surfaces

How do I clean and store the grill mat after use?

Cleaning is simple: wipe away grease with a cloth or hose the mat and let it air dry. Because both sides are coated and non-slip, the mat resists stubborn residues; occasional mild soap removes tougher sticky sauces without harming the silicone finish.

• Wipe with a damp cloth for light spills
• Rinse with a hose for heavier messes, then air dry
• Use mild detergent for dried-on residues
• Fold or roll for compact storage between uses

Is the Demiwise mat durable and safe for outdoor use?

Built from modern fiberglass materials and reinforced silicone coatings, the mat is designed to resist tearing, UV exposure and repeated temperature cycles. While it provides a high degree of heat resistance and protects surfaces from embers and ash, it should not be used as an active flame barrier or left under a grill with open flames directly contacting the mat.

• Fiberglass resists high temperatures and tearing
• Silicone surface reduces wear from foot traffic and spills
• Lab-tested for durability before shipping
• Not intended as direct flame contact protection

Who is this for? Grillers, patio owners and campers who want simple, dependable protection for decking, pavers and lawn areas will appreciate the Demiwise 48x36in mat. It’s aimed at people who cook outdoors frequently and need an easy-to-clean, foldable shield that fits most medium grills, smokers and portable fire pits. Choose this mat if you want a lightweight, high-temperature-resistant barrier that reduces cleanup and preserves outdoor surfaces without permanent installation.
