1. Fire pad

Fire pads are specially designed to protect composite decks from heat embers coming out of fire pits. Mats are quite thick which enables them to tackle harm done by high heat.

These fire pads are available in a variety of shapes sizes and textures. To ensure that fire pads save the deck from maximum damage, place the fire pit in the centre of the mat.

For further protection do not place a direct fire pit on the mat. Use any stand or other support to lift it from the surface.

2. Heat-resistant tiles

Heat-resistant tiles are designed in such a way that they can handle high heat well. These tiles are made of tough materials such as concrete, stone, ceramic, and clay that are well known for their heat resistance.

These are sturdy tiles that can last for a longer time. You won’t have to replace these tiles very often. And above all, you don’t have to worry about damaging the underneath deck surface. They will protect the deck surface from fire cinders coming out of the fire pits.

4. Cement tiles or board

How to Safely Use a Fire Pit on a Wooden Deck

It’s crucial to emphasize that when using a fire pit, whether on a wooden deck, in your yard, or anywhere it must never be left unattended.

1. Clear the Deck

Before lighting a fire in your fire pit, ensure that the surrounding area is free from debris. Relocate leaves, pine straw, old newspapers, lighter fluid, or any other highly flammable materials far away from the fire pit.

Remember that fires can pop and crackle, potentially sending embers flying from the fire pit. If an ember lands in a pile of dry leaves or debris, it could ignite, leading to the spread of fire. Sweep the area clean to establish a safe, clear zone around the pit.

2. Move Away from the House

Never position your fire pit directly against the side of your house, garage, or any other structure. Although this should be common sense, people might not fully consider the consequences of starting a fire. Being outdoors alone does not ensure safety.

Apart from the risk of your home catching fire, fire pits emit a substantial amount of heat that can damage siding, resulting in unsightly exteriors or costly repairs.

Moreover, maintain a distance of at least 20 feet between any fires and your home. If your deck is too small to allow for this distance, it’s best to avoid having a fire pit altogether. Consider donating it to a friend with a more appropriate space.

3. Use Pavers Underneath the Fire Pit

For similar reasons, never place a fire pit directly on a wooden deck. The intense heat generated by the fire can scorch, singe, or even weaken the deck’s structure.

In addition to this, specialized fire pit mats designed to withstand high temperatures are available, or you can use pavers or bricks to create a protective barrier between the fire pit and the deck.

4. Dispose of Ashes Properly

Wait until both the fire pit and its contents have cooled completely around 24 hours before properly disposing of the ashes. Scoop the ashes out of the pit and into a small metal bucket or another suitable container.

Moreover, leaving the ashes inside the pit can lead to corrosion over time, especially when they become wet. Additionally, windy conditions could blow ashes out of the pit and onto your deck. You can find surprising uses for wood ashes, such as aiding plant growth and de-skunking pets.

5. Keep Water on Hand

Having a nearby fire extinguisher is essential, it’s also a good idea to have a source of water readily available. For many households, an outdoor hose is nearby, but you can also keep a covered bucket, tub, or pitcher filled with water near the fire pit. Rainwater can serve this purpose as well.

Water is easier to use than a fire extinguisher and is effective at extinguishing small fires. However, if a fire gets out of control, don’t hesitate to use the fire extinguisher.
