RESILIA X-Large Under Grill Mat 57 in x 47 in - Heavy Duty Deck

In this review of the RESILIA X-Large Under Grill Mat the bottom line is clear: this is a practical choice for homeowners who want a low-maintenance, heavy-duty floor protector that stands up to grease, charcoal and regular outdoor use. The mat's biggest selling point is simple durability - a textured, flame-retardant propylene surface that resists spills and wipes clean with a rinse. It is best for patios, garages, and traditional wood decks where long, easy protection is the priority rather than decorative finish on composite decking.

Key Features

• Flame-retardant surface: Provides a safer mat under grills by resisting ignition and reducing heat-related risk when used with proper clearance.
• Grease and stain resistance: Shields floors from oil, rust, charcoal and grease drips to prevent costly discoloration and damage.
• Textured, non-slip finish: Adds traction for safer footing while cooking outdoors and helps keep the mat and items placed on it stable.
• Easy to clean: Skip scrubbing-most messes rinse away with water so maintenance is quick and simple after use.
• Made in the USA with recycled content: Constructed from propylene at a family-owned facility in Wheeling, Illinois, with an emphasis on recycled material and safe manufacturing.
• Versatile protection: Works beyond grilling to protect floors from lawn equipment, tools, snowblowers and plant spills for year-round use.

Who It's For

This mat is ideal for grill owners who need a large, durable protector to sit under a freestanding grill on a porch, patio or garage floor and who value low maintenance and long wear. It suits users who want to prevent grease and food stains without frequent replacement and prefer a functional, industrial look over decorative detail.

It is not recommended for composite decking, as the manufacturer warns of possible discoloration, and it should not be used under fire pits or where less than 18 in clearance is available. If a decorative or thin indoor rug appearance is required, or if you plan to place it on sensitive composite surfaces, consider other options.
