Things to Consider Before Buying Grill Mats for Composite Decking

There are several kinds of grill mats on the market. Each of them is different having specific features. An online search can leave you in utter confusion.

Herein are certain factors to focus on when buying a grill mat. So, just dive in to explore them to choose the perfect fit for your needs.

#1. Weatherproof

BBQ grills are mostly used outdoors- on the deck, patio, etc. Hence the grill mat is exposed to rainwater, sunlight, wind, and high temperature. A weatherproof mat lasts longer compared to their cousins. Spending a few bucks more on weatherproof grill mats makes sense.

#2. Anti-Skid/ Slip Proof

Some grill mats have superb glossy sheen surfaces. The overall appearance may often tempt the buyers to add the item to the cart at an instance.

Herein you need to put in a second thought. The shiny smooth surfaces can be slippery. The grill equipment is heavy and stays firm on the mat.

However, these mats can be dangerous for people stepping on the surfaces. Kids may encounter slips and fall issues when playing nearby.

Think about the sharp objects nearby the grill- knives, pointed skewers, and others. An accidental fall on these objects can lead to serious injuries.

Moreover, the person preparing the food is also at a risk. You don’t want the chef to fall or tumble down with the food, get bruises, or burns due to the hot grill. Right!

#3. Heat-Resistant

Some grilling equipment supports high-temperature cooking. The temperature on the grates can surge up to 700°F or even beyond. Obviously, the heat will proliferate down to the ground.

Cheap plastic mats may not be the ideal thing to bear high temperatures. Choose an item that can withstand extreme heat.

#4. Fireproof

We wish to buy a fireproof grill mat. Unfortunately, non of the mats are 100% fireproof.

However, some items are crafted to advanced design to resist the fire impact to a great extent. These items take more time to catch fire. So you will have enough time to extinguish flames.

#5. Ease of Cleaning

Consider the purpose of using a grill mat. It protects your floor. After a BBQ party, it will be messed up with all the juices, sauces, fat splatters, and so much more.

If your mat takes too much time to clean, it can be an extremely tiresome job. Take a look at the cleaning instructions. Your mat should be easy to clean using detergent and hose water spray.

#6. Size

Choosing the grill mat size depends on a lot of aspects. Consider the overall dimensions of your equipment, patio area, etc. Your grill mat should be at least 30% bigger than the grill.

For me, a bigger anti-skid and slip-proof mat offer the best user experience. Don’t mind if it costs extra for a large one.

In the due course, it will save money on expensive flooring renovations.

#7. Durability

High-quality material offers long-lasting performance. Some sturdy mats will last for years without giving you much trouble.

#8. Warranty

If an expensive mat goes through severe damage within is short span, it feels disgusting. Herein the extended warranty period comes to the savior.

Some popular brands offer free replacement so that you can get a new one against the damaged item. That’s great!
Kudos to the friendly customer support services.

#9. Spillproof/ Absorbent

This is one aspect many buyers overlook when choosing grill mats. An absorbent mat can soak up all the juices and splatter fat easily.

Avoid PVC mats that won’t soak up the liquids. It can make the surfaces oily and slippery. In the worst case, the sauces can spill down to the flooring area. Such mats are useless as these won’t protect your floor from stains or grease deposits.

Mats capable of absorbing the sauces and fat splatters are safe to keep the surfaces safe and non-slippery.

What is Grill Mat for The Deck?

The grill mat is an extremely handy implement that acts as a defensive shield for the deck from the incessant destructive and spoiling encroachment of splashes and spilling of grease, sauces, and other liquids during cooking.

Therefore, it is a low-cost protective item for the highly expensive deck. Using folded canvas under the grill or pit as a low-cost alternative to grill mat is an illusion that plays a double whammy. After a very short span, spills and splashes ruin the tarp and remain stuck to the mid grease.

Why Grill Mat is Essential for Deck?

Among the two most popular, highly durable mats (soaking, repelling) have many positives and few negatives. The first one, a foldable mat, will entrap the grease and soak them up into the porous soak-able layers. Furthermore, it is easy to carry and clean using hose water (no scrubbing required).

The other one applies repulsive contents forcing the grease to settle atop the mat, which is cleanable later.

On the flip side, the repellent mat becomes a source of danger if there are children and pets around the deck. Hence, using such items as amateurish and unprofessional.

The grill mat maintains the cleanliness of the grilling space and also protects the deck and floor as well as lengthen the life of the deck.
