rumlick under-grill mat 79 x 39 inches — large heat-resistant fiberglass, waterproof deck protector for grills

rumlick's 79 x 39-inch under grill mat is a large, double-sided fiberglass mat designed to shield decks, patios and lawns from sparks, grease and food debris when using Blackstone and other family-sized grills.

This oversized under-grill mat combines a high-temperature fiberglass core with waterproof silicone coatings to catch falling embers, hot grease and food drips while staying easy to clean and reusable season after season. It fits most family grills and provides a wide protective footprint so you can position your griddle or BBQ without worrying about surface stains or burn marks. The mat is foldable for storage and light enough to move between backyard setups, tailgates and camping sites.

How does this mat protect my deck during grilling?

The mat acts as a physical barrier between your grill and whatever surface is beneath it, catching sparks, grease splatters and food particles before they contact wood, pavers or grass. Its fiberglass body resists high temperatures while both sides are coated to stop liquids from soaking through.

• 79×39-inch coverage shields a broad area beneath most family grills
• Fiberglass core offers thermal resistance to reduce heat transfer
• Double-sided silicone coating prevents grease and liquids from penetrating
• Catches embers and food debris to keep surfaces clean

Is the rumlick mat easy to clean and maintain?

Yes — the silicone-coated surface repels oil and water so most spills stay on the surface for quick removal. For regular messes, a garden hose, damp cloth or mild detergent will remove stuck-on grease and residue, and the mat dries quickly without staining.

• Oil-proof, waterproof surface wipes clean with a cloth
• Hose off stubborn grease and let air-dry
• Resists staining for repeated seasonal use

How hot can the mat handle and where should I use it?

The fiberglass construction with heat-resistant silicone coating is engineered to tolerate high temperatures from falling embers and hot grease, protecting underlying surfaces. It’s made for outdoor grilling, tailgating, and many fire-protection scenarios, though direct contact with open flames should be avoided to extend the mat’s lifespan.

• Heat-resistant fiberglass core designed for ember and grease protection
• Suitable for grills, griddles, fire pits and campfire areas (not as a flame-retardant platform)
• Foldable and portable for camping and tailgating use

Will this mat fit my Blackstone or other family-sized grill?

The generous 79 by 39-inch dimensions accommodate most Blackstone models and many family-sized grills, offering ample coverage for common backyard setups. If you have an oversized or custom grill, measure the footprint to ensure full protection.

• Designed to fit most family grills and Blackstone griddles
• Large footprint reduces need to reposition the grill
• Portable size folds for compact storage between uses

Who is this for: The rumlick 79×39 under grill mat is aimed at homeowners, tailgaters and campers who use family-sized grills and want an easy-to-clean, reusable barrier that reduces cleanup and protects wood decks, patios and lawns from grease, sparks and food debris. It’s a practical accessory for anyone who grills frequently outdoors and prefers a low-maintenance, wide-coverage solution to protect surfaces.
