How to Choose the Best Waterproof Tent Spray?

Before buying the best waterproofing tent spray, you need to follow some important considerations. Your choice matters when it comes to a quality inspection phase. Like, you bought a spray, and it is not working great, as well as at the end of the day, it will be a wastage of money.

There are three important considerations that you may follow before buying the best waterproofing tent spray.

  1. Tent fabric type
  2. Silicon or Non-Silicone Spray?
  3. Spray Bottle or Aerosol?

Apart from these major considerations, there are some other important facts that you should check before buying the waterproofing spray in 2021. Let’s talk about the facts first:

  • Weight should be checked so that you can easily transport it to your bag.
  • The solution of the spray should be quality so that you get a good result from it.
  • The shape of the spray bottle or aerosol should be comfortable in handling so that you can comfortably spray over the fabric.
  • The using process should be easy for beginners so that they can have an even spray over the fabric.
  • The spray should have the quality to maintain the breathability of the applied fabric.
  • The sprayer should be suitable for different uses where you can use it in multiple outing equipment and apparel.

Now it’s time to discuss the considerations that you should follow before purchasing a waterproofing spray.


Tent Fabric Type

There are three choices for you to choose a tent fabric type. Though most fabric types are of regenerated or artificial fiber, there are some differences between them.

The three main types of tent fabric are-

  1. Nylon
  2. Polyester
  3. Canvas

If you go for the canvas fabric, you need to find the best waterproofing spray for canvas tents, and you may not find them so easily. We will recommend you to go for the Nylon or polyester-made tent fabric though the canvas-made tent is gorgeous to see.


Silicone or Non-Silicone?

When you are thinking about- should I go for silicone-based spray or non-silicone-based spray and the professionals, on the other hand, always going for the silicone waterproof spray. So,


What are you waiting for?

Silicone is the best sealing material, and it has the chemical property to seal the solid fabric with a strong chemical bond. Again, silicon is used in other solid materials to seal them and save them from leakage like- sinks, bathtubs, etc.

If you want durability with efficiency, you should choose a silicone-based and non-silicone-based spray that won’t last long though they are cheaper.


Spray Bottle or Aerosol?

 As you are seeing there are two types of sprayer- one is a spray bottle and another one is aerosol. So, which one should you choose? Both of them have their pros and cons which we will show in a table so that you can easily decide according to your situation.


Spray Bottle Need to pull a trigger and spray You will have actual control over the sprayer Uneven spraying may occur several time
Aerosol Press and spray Easy to spray and more efficient Harmful for nature and need more sprays for covering an area


Well, you have seen the comparison table, and it has ended up with the solution that you can pick both of them according to your need. If you can control the spray bottle accurately, then the uneven spraying can also be controlled, and you will get up to 90% even spraying. So, the choice is yours.


Difference Between Seam Sealing and Waterproofing Spray

As you know that it is common to face a leak in your tent fabric, and you need to be careful about leaks and punctures. You may think about a waterproofing spray- will that work properly, or should you go with seam sealing with a seam tape or solution?

When you get to know about their property, you will understand what is better for you though we will recommend the best way to waterproof your tent.

The tent is made of different parts of the fabric, seaming together, and found some leaks and punctures inherently after using some days or in the new one.

To seal the leaks, you can use a seam sealing solution or seam sealing tape. So, which is the best tent seam sealer among these two?


Seam Sealer Solution

Diluted silicones can be prepared both in-home and factory to use with a brush on the seam line area. This solution of silicones should ‘warm honey, and before it loses the high temperature, you should apply it.

When you brush the silicon solution along with the thin line of the seam, it will penetrate the seam leakage left by the seaming machine. It works better and offers an instant result.


Seam Sealer Tape

This is a thin stripe-looking material that is waterproofed and can be applied in the seam line. But, with time, the stripes will peel off, and water will come inside again even if you don’t use your tent for a long time. The stripe will gradually lose the stickiness and result in peeling off fast.

When you are done with your seam sealing and facing the same water problem, you should use the waterproofing spray above them to re-sealed the leaks.

How to Apply Waterproof Tent Spray?

When you are ready to follow some simple steps to waterproof your tent with a spray, you will get the best result. Let’s know how to apply the best tent waterproofing step by step.

Step 2: Minimal Sun Ray and Wind

The strong sun rays are harmful to the tent spray as it is a chemical, and it needs to react with the tent’s fabric. So, to have minimal sunlight and wind, you can choose your garage to perform this step.

Step 3: Spray

You need to grab your best tent waterproofing spray and spray it over the tent fabric in this step. After spraying, the chemical reaction will start.


Step 4: Dry
