70 x 48 in Under Grill Mat Compatible with Blackstone 28in & 36in

In this review the 70 x 48 in under grill mat is judged on protection, durability and cleaning ease for backyard griddles and portable cook stations. It is aimed at homeowners and renters who use a Blackstone 28in or 36in griddle or similar outdoor cooker and want a reliable surface barrier. The single biggest reason to buy is its combination of large coverage and high heat resistance, which reduces the risk of grease stains, food splatters and scorch marks on decks, patios and pavers.

Key Features

• Size 70 x 48 in: large footprint gives full coverage under common 28in and 36in griddles so spills and splashes are caught before they reach the deck.
• 2000F fireproof material: fiberglass core with silicone resin coating provides extreme heat resistance to protect underlying surfaces from hot drops and embers.
• Oilproof surface: the smooth, waterproof finish resists grease and makes routine cleanup as simple as rinsing with a hose or washing with dish soap.
• Flat wrap-around design: stays flat without curled edges to eliminate tripping hazards and allow the griddle to be moved without catching corners.
• Outdoor surface protection: shields wood, pavers, cement and lawn from stains, spills and potential burn marks during heavy use.

Who It's For

This mat is best for backyard grillers who operate medium to large flat-top griddles and want broad coverage to keep decks and patios clean. It suits homeowners with wood decking, stone pavers or concrete patios who are concerned about grease stains and scorch marks from frequent outdoor cooking.

It may be less necessary for people who only use a small tabletop burner or always grill on dirt or gravel where underlying surface protection is not required. Those who need a heavily cushioned mat for anti-fatigue or large commercial setups should look for thicker, purpose-built commercial pads instead.

Pros & Cons

Pros

• Large 70 x 48 in coverage protects a wide area under the griddle.
• High heat resistance from the fiberglass and silicone resin construction reduces burn risk to the deck.
• Easy to clean oilproof finish speeds post-cook cleanup with just a hose or soap and water.
• Design stays flat without curled edges, improving safety and usability.

Cons

• Perceptions of thickness vary; some users find it thin while others call it thick, so it may not feel substantial to everyone.
• Not a replacement for full commercial-grade insulation where heavy-duty heat soak or structural protection is required.

Frequently Asked Questions

Will this mat work with a 28in Blackstone griddle?
Yes. The 70 x 48 in size is designed to be compatible with 28in and 36in Blackstone-style griddles and provides ample coverage around the appliance.

How do you clean grease off the mat?
Grease and food residue rinse off easily with a garden hose or can be cleaned with dish soap and water on the smooth, oilproof surface.

Is the mat heat resistant enough for hot embers or grease fires?
The fiberglass core with silicone resin coating is rated to 2000F for strong heat resistance, but it is not a substitute for safe grilling practices or commercial insulation in extreme industrial conditions.
