The purpose of putting sand in the bottom of a fire pit is to provide heat for your fire, but it’s also useful because when you leave the campfire unattended and walk away from it, most fires will put out on their own. However, if there was no sand at all or just a little bit too much water in the pool below your fire pit then that would cause problems with your camping experience.

The “what kind of sand do you use in a fire pit” is a question that has been asked for years. The most common answer is to put sand in the bottom of your fire pit so it stays cool.

A fire pit may be used for a variety of purposes. It may be used for bonfires, s’mores, and a variety of other things in addition to cooking up some delicious BBQ. A fire pit is a valuable item to have in your yard.

However, one component of the fire pit causes considerable confusion: the sand in the bottom. You may or may not have heard of people filling their fire pits with sand and questioned why this is the case.

Some fire pit manufacturers may even suggest it for use with their metal fire pits.

Why Sand?


The rationale for putting sand in your fire pit (link to amazon silica sand) is straightforward. The metal at the bottom of the bowl is protected by a layer of sand from the tremendous heat of the fire. The sand absorbs the heat and uniformly distributes it across the pit’s whole foundation.

Without the sand, heat might get concentrated in a single spot. When this occurs, the metal at the bottom of the fire pit may corrode and eventually burn through.

The sand functions as a heat dissipator and acts as an insulator against such high temperatures.

Remember that fire need oxygen to survive. As a result, there are several kinds of fire pits. At the bottom of some, there will be holes. This allows for optimal air movement from both above and below the bowl, which helps to keep the fire raging.

Because of the bowl’s form, air may flow even without the openings. Some argue that adding sand would actually block airflow, making it more difficult for the fire to fully burn.

Some people choose not to use sand in their fire pits. This is due to the fact that wood fire ash may be utilized as a fertilizer. For enthusiastic gardeners, having access to that ash can be useful.

This implies that the sand may be less than optimal for individuals who want to grow wood ash for later use. It all boils down to personal choice when it comes to your fire pit.

Making Use of Sand


Before you buy a fire pit, make sure you read the manufacturer’s instructions carefully. Each manufacturer has its own set of guidelines and instructions, which should not be disregarded.

The majority of them will advise layering the bottom of the fire pit with an inch or two of sand. There are certain manufacturers that do not need the use of sand, which might save you time and money.

Cleaning up the sand might be tedious after a time, particularly if you wish to maintain the ash while cleaning the sand. Sand, on the other hand, is an excellent technique to insulate the bottom bowl of the fire pit from the intense heat that the fire may produce.

There are also more reasons why sand should not be used at the bottom of a fire pit. The first is that sand is a moisture-retentive material.

So, although the sand is supposed to insulate the bowl from heat accumulation, it may actually hasten the corrosion of the bowl if it is exposed to moisture on a frequent basis.

The second reason is that some metal fire pits come with drainage and circulation holes already drilled onto the bottom. By putting sand in the bottom of the bowl, the air will be unable to circulate, defeating the purpose of the holes in the first place.

Keeping Your Fire Pit Safe


Keep in mind that sand alone won’t keep your fire pit safe. Yes, it will shield the bottom of the bowl from the high heat produced by a fire. However, it is the extent of its protection.

Some manufacturers will advocate the sand, while others would remain silent. You should definitely use sand if the manufacturer suggests it.

But, at the end of the day, you’ll need to take additional precautions to preserve your fire pit from harm.

Rust is one of the most common problems with fire pits. Rust may not only make the fire pit seem unsightly, but it can also wear down the metal, resulting in holes and chipped areas.

The only way to really secure the fire pit is to properly maintain it. If you don’t want it to rust and break down, don’t keep it outside in the weather.

When you aren’t using the fire pit, put it away or buy a protective fire pit cover (make sure you obtain the proper size). That cover will keep it secure from the elements on a patio or in the backyard until you need it again.

It’s also a good idea to invest in a rust-resistant, high-temperature spray (like this one). This will help prevent rust from accumulating on both the inside and outside of the bowl. This will keep your fire pit looking excellent while also keeping it useful.

Finally, if you do add sand to your fire pit, it is a good idea to periodically check the moisture levels. Any more moisture might be held in the sand and ultimately distribute to the bowl, causing corrosion, depending on your environment.

Consider discarding the sand and replenishing it if it is too wet. That will go a long way toward preventing rust and ensuring that your fire pit performs at its best for a long time.

Your fire pit can be a delightful addition to your home that serves multiple purposes. But it’s also crucial to keep it safe. A little planning ahead of time and a protective cover may go a long way toward keeping your fire pit looking and functioning as it should.

The “paver sand for fire pit” is a question that many people ask. The answer is to add sand in the bottom of a fire pit. This will help prevent the fire from going out and also create a nice layer of heat.
