Cuisinart Premium Deck and Grill Mat
Material and size: 100% PVC, 65” x 36” for broad coverage on decks, patios, or porches. Weather-resistant to stand up to rain, sun, and frequent use. Best for: homeowners with wood, composite, or concrete surfaces who want all-season protection from grease and spills.
Why selected: Its non-slip design helps keep the mat in place beneath grills and griddles, reducing shifting during cooking. This makes it a reliable choice for standard deck grills and griddles.
Limitations: PVC can be less forgiving on very irregular or angled surfaces, and durability depends on exposure to harsh sunlight over time.
SHINESTAR Under Grill Mat

Why selected: The large coverage area and high heat resistance help prevent damage from embers and grease while staying in place thanks to the non-slip backing.
Limitations: Heavier mats may require more storage space and occasional edge maintenance to prevent curling over time.

Buying Guide: Key Considerations For Choosing A Grill Mat For Composite Decking
- Deck compatibility: Look for mats specifically described as suitable for composite surfaces, with non-slip backing to reduce movement.
- Size and coverage: Choose a size that provides ample protection for your grill footprint and any nearby walkways or seating areas.
- Material and heat resistance: For high-heat cooking, consider fiberglass or high-temperature silicone coatings; PVC mats are durable but can be stiffer.
- Waterproof and grease resistance: A waterproof barrier minimizes staining; a grease-proof surface simplifies cleaning.
- Durability and storage: Thicker materials with reinforced edges resist curling; check for foldable or rollable designs for easier storage.
- Maintenance: Reversible or easy-clean surfaces save time after barbecues; verify if mats are hose-cleanable or require soap and water.
