Demiwise Grill Mat 76x48in Extra-Large Patio & Deck Protector — Fire-Resistant, Waterproof

The Demiwise 76x48in Grill Mat is a heavy-duty, fire-resistant patio and deck protector designed to catch spills, embers, and grease from grills, smokers, and flat tops while withstanding extreme temperatures.

Protecting outdoor floors from grease stains, falling charcoal, and high heat is easier with a purpose-built mat. This extra-large Demiwise model (also available in 48x36 and 65x48 sizes) is made from high-grade fiberglass with silicone coatings on both sides for waterproofing and slip resistance. It fits most freestanding grills, gas or charcoal smokers, griddles and fire pits, and folds compactly for storage or transport.

How does this mat shield my deck or patio from grill damage?

The mat provides a barrier between hot embers, grease and the surface beneath your grill. Its fiberglass core resists very high temperatures while the silicone coatings prevent oil and liquids from soaking through, so wood, composite decking and pavers remain unstained and protected.

• High-temperature fiberglass core resists heat up to approximately 2000°F.
• Silicone-coated surfaces block grease, soy sauce and liquid spills.
• Larger footprint (76x48in) covers an extended area under most grills and fire pits.

Will it work with different grill types, smokers and outdoor appliances?

Yes — the mat is sized and constructed to sit under a variety of outdoor cooking equipment. Its thin, foldable form fits beneath gas grills, charcoal grills, flat tops and small smokers, and it won't interfere with ventilation when placed correctly.

• Compatible with charcoal, gas, electric grills, griddles and many smokers.
• Available in three sizes to accommodate compact or larger setups.
• Low-profile design allows stable placement on flat surfaces.

How easy is the Demiwise mat to clean and store after use?

Maintenance is straightforward thanks to the silicone coating on both sides. Wipe away grease and ash with a damp cloth or rinse with a hose; the material is light enough to fold and carry to a mop sink or storage bin.

• Wipe clean or hose down — quick drying and water-resistant.
• Thin, flexible construction folds for compact storage and transport.
• Non-slip surfaces help keep the mat and grill steady during use.

What makes Demiwise quality and safety reliable?

Demiwise uses a new fiberglass-based composite that combines strength and temperature tolerance with a lightweight profile. Each mat undergoes lab testing and quality checks before shipping to help ensure consistent performance and long-term durability in outdoor settings.

• Fiberglass material resists tears and deformation over time.
• Double-sided high-temp silicone coating enhances fire resistance and prevents staining.
• Quality-inspected units designed for repeated outdoor use.

Who is this for: Homeowners and outdoor chefs who want reliable floor protection when grilling, smoking or hosting backyard fire-pit gatherings will benefit from the Demiwise 76x48in Grill Mat. It’s especially useful if you have wood or composite decking, frequent charcoal grilling, or need a lightweight, foldable protector for travel, tailgates and seasonal storage.
