Buying Guide for the Best Under Grill Mat For Composite Deck
Choosing the right under-grill mat for your composite deck is important because it protects your decking from grease, spills, and high temperatures. Composite decking can be sensitive to stains and heat damage, so using a suitable grill mat helps keep your outdoor space looking great. When selecting a mat, pay attention to the material, size, heat resistance, ease of cleaning, and slip resistance. Your choice should be guided by the type of grill you have, the size of your grilling area, and how much protection you need.MaterialThe material of an under-grill mat determines how well it protects your deck from grease and heat. Common materials include rubber, PVC, and specialized fibers. Some are better at resisting high temperatures, while others excel at soaking up spills. For composite decks, it's especially important to choose mats labelled as safe for composites, as some materials can react with the decking and cause stains. If you grill often or use high-heat grills, look for mats made of fire-resistant and non-reactive materials.
SizeThe size of the under-grill mat should cover the entire area beneath and around your grill where spills or sparks might land. Mats are available in a range of sizes, from small ones designed for portable grills to large mats covering wide grilling zones. To pick the right size, measure your grill and allow extra space around the edges for messes. If you have a big grill or frequently entertain, a larger mat might be a better fit; for smaller, occasional use, a compact mat should do the job.
Heat ResistanceHeat resistance tells you how well the mat can handle the high temperatures that come from grilling. Not all mats can withstand the same amount of heat—some might warp or melt if exposed to high temperatures for too long. Mats typically fall into segments like basic protection (with lower heat thresholds), standard heat resistance (suitable for gas and charcoal grills), and heavy-duty (able to handle very high temps or direct contact with hot objects). If you use a grill with intense heat or if flare-ups are common, opt for a heavy-duty, heat-resistant mat to keep your deck safe.
Ease of CleaningAn under-grill mat will catch grease, sauce, and burnt bits, so being able to clean it easily is a real advantage. Some mats can simply be wiped down, while others might need hosing off or even machine washing. There are basic mats that are single-use or need replacing, and reusable mats designed for repeat cleanings. Pick a mat that matches your cleaning preference and the amount of mess you expect—if you grill often or cook messy foods, a washable, durable mat is likely the best fit.
Slip ResistanceSlip resistance refers to how securely the mat stays in place on your composite deck, even if it gets wet or greasy. Some mats have textured backings or weighty builds that help prevent slipping and sliding. There are mats with basic grip (good for light grilling and dry weather), standard grip (suitable for regular use), and high-grip surfaces (best for heavy grilling or wet conditions). If your deck is especially smooth or you move around a lot while grilling, a mat with strong slip resistance is a safer option.
