70 x 48 in Under Grill Mat for Outdoor Grill - Extra Large Deck

In this review the focus is practical: a large, inexpensive way to protect wood and stone surfaces from grease, spills and heat when cooking outdoors. The 70 x 48 in under grill mat is aimed at homeowners who grill on a deck, patio or pavers and want a low-maintenance barrier beneath a charcoal, gas or smoker grill. Its single biggest selling point is coverage - the extra large 70 x 48 in size keeps most splatters and drips off the deck, and the smooth, oilproof surface makes cleanup simple after a busy cookout.

Key Features

• Extra large size: The 70 x 48 in dimensions cover a wide area so the mat protects underneath the grill, prep table and the immediate cooking zone.
• Fireproof construction: Fiberglass core with heat resistant silicone resin on both sides offers protection against high temperatures up to the material's rated tolerance, which is intended for heavy grill use.
• Deck and patio protection: Designed to shield wood, pavers, cement and lawn from grease splashes, stains and scorch marks caused by grilling.
• Oilproof surface: A smooth, nonabsorbent finish repels grease and food drips so most messes rinse away with a garden hose or light dish soap.
• Flat, noncurling edges: The wrap-around design lies flat to minimize tripping hazards and lets wheels and feet move the grill without catching curled corners.

Who It's For

This mat suits backyard cooks who need broad coverage under a gas, charcoal or smoker grill and want an easy-to-clean surface that resists grease and staining. It is particularly useful for those with wooden decks or lighter colored pavers who worry about permanent stains or scorch marks.

It is less appropriate for buyers who need a thick, heavily cushioned pad or who expect substantial wind anchoring; some customers describe the material as thin and recommend additional measures if wind or long-term heavy wear is a concern.

Pros & Cons

Pros

• Large 70 x 48 in coverage keeps spills and splatters off deck surfaces.
• Fireproof fiberglass with silicone resin coating provides heat resistance for typical grilling scenarios.
• Oilproof, smooth surface makes rinsing and cleaning quick and simple.

Cons

• Material is thin at 1mm, so users seeking heavy-duty padding or long-term abrasion resistance may prefer a thicker option.
