How Do You Waterproof a Gun Safe?

Keeping your gun safe out of water can become a must-do thing sometimes. If you already have a gun safe and planning not to buy another with a waterproof rating, you can make it waterproof quickly. Here are the things you should know and the steps you can take to make your existing gun safe waterproof:

How Do You Waterproof a Gun Safe

Elevating the safe off the floor

Most people usually place their guns safely on the ground floor to the corner of the room for the safest placement. If you suddenly get a disaster strike and have to keep your gun safe off the water instantly, getting it off the ground is the best idea. The first thing you can do is, get some concrete or wooden blocks and place them under the gun safe. They will elevate the gun safe from the ground and keep it away from the water. You can get the weather forecast, determine how high the water may rise, and get the safe off the ground to that level using slabs.

Give it some good pain jobs

The next thing you must consider is the exterior of the safe, especially if it’s a cheap or old gun safe. It’s highly likely that a cheap or an old gun safe would get weakened over time, especially at its bottom. The bottom of the gun safe where it rests can serve you at its best if you get it a waterproof paint job. It will make the external of the safe capable of fighting the humidity around the safe when the water is around.

Getting the gun safe to high ground or upstairs

If the flood doesn’t seem to stop at a level and tries to get into the gun safe even after getting it off the ground, get it upstairs. However, it’s only possible if you have the floor above your head or a roof with a stair to it and sturdy enough to hold onto the safe. You can also make a platform for the gun safe if you don’t have a floor to climb with the gun safe.

Consider a moisture barrier

Maybe you have secured the gun safe from the direct contact of the water, but that doesn’t mean it’s safe! You must keep it safe from the humidity and the moisture to keep the interior and the belongings safe. One of the most effective ways of making a room moisture-free is to make a moisture barrier. You have to install the moisture barrier before you put slabs on the floor under the gun safe. However, make sure the barrier is strong enough to withstand the weight of the safe; a hard rubber mat would do the job. If you can spend some extra money, getting a vapor barrier like a vinyl siding could be the best option.

Seal all the holes and the door

Sealing the holes in your gun safe can help you keep the water vapor and the humidity gets inside the safe. You may have holes or passageways for the air to go inside the gun safe and damage the inside. Use some RTV, High-Temperature Silicone Sealant, or some sealing solution to make the inside of the safe air and watertight. You can also use a waterproof container inside the safe to keep the guns, metal goods, or money safe even if water gets inside. So, even if you ask how are gun safes waterproof, you can make it through during a flood or disaster.
