Buying Guide – How to Choose the Best Waterproofing Spray For Outdoor Fabric

Even the highest quality waterproof clothing and gear require reproofing. Using gear that has lost its water repellency in the outdoors leaves you vulnerable. In fact, fabric that has lost its water repellent properties will quickly lose its durability.

This is why it’s important to invest in a waterproofing agent to help preserve your clothing and gear. In the buying guide below, we’ve shared key features for choosing the best waterproofing spray for outdoor fabrics. In addition, the guide walks you through selecting a spray formulated for your gear.

  • Ingredients

Waterproofing sprays integrate a choice of two ingredients. They comprise silicone-based or water-based sprays.  Due to the lighter and somewhat runny consistency, water-based sprays function best for more lightweight gear such as clothing and shoes. On the other hand, silicone-based sprays work best for heavy-duty fabrics such as tents or furniture covers. 

Nevertheless, all waterproofing spray formulas feature some kind of chemical. Thus, contact with the spray can cause skin irritation. You may also inhale the sharp odour during application– although it’s not harmful.

Therefore, you should make it a point to apply the spray to your gear in a well-ventilated area. If you have pets or small children, avoid having them in the room when applying the waterproofing spray. When done using the waterproofing spray, store it where your children or pets cannot access it.

  • Protection

The best outdoor fabric waterproofing spray is designed to add or renew the water repellency of a material. The functionality scope of the spray depends on its formula. Some spray work for a particular type of fabric, whilst others feature a universal solution. 

This means that they work for almost all fabrics – such as nylon, canvas, leather, and so on. Additionally, some waterproofing sprays work best for gear such as your clothes, footwear, and backpacks. Other waterproofing sprays are more heavy-duty – allowing you to use them on your tents, equipment, and furniture covers.

Furthermore, you may find waterproofing spray formulated with extra features. For example, you may find waterproofing agents such as scotch guards that protect your gear against sun damage, thanks to the UV protection it offers. However, as their scope of use increases, so does their price.

  • Performance

There’s no doubt that the best waterproofing spray for outdoor fabrics delivers superior water repellency and protects the longevity of your fabrics. These proofing agents are designed and advertised to leave fabrics as they are.

However, in reality, this is further from the truth. This is because even the best waterproofing spray for outdoor fabrics will cause some colour changes on your fabric. The good news is that you shouldn’t occupy your mind too much with this. You will only notice slight colour changes during the coating and curing process.

After the process, you will notice your fabric colour returning to its original shine. Additionally, to ensure the colour change isn’t permanent, make sure you evenly apply the waterproofing spray across the entire fabric with the same thickness.

Another factor you will notice in some waterproofing sprays is the odour. This is a more common occurrence in silicone-based waterproofing sprays rather than water-based ones. Nonetheless, after the proofing agent dries out, the smell tends to disappear.

  • Breathability

Good quality waterproof gear designed should offer good breathability and moisture-wicking properties. So, when applying the spray, you don’t want it to affect breathability. The best option should provide adequate water repellency. Yet, it shouldn’t seal the fabric too much so that it compromises its breathability.

The spray produces liquid formula. So, compromising breathability will ultimately affect the durability of the fabric. This is because, with the lack of breathability, the waterproofing agent creates a humid environment. A moist environment acts as a perfect breeding ground for bacteria.

  • Application

You want to ensure you apply the waterproofing agent correctly as this affects its effectiveness. Waterproofing spray comes in either a spray bottle or a can, allowing you to apply it directly. A spray can is much easier to handle as it applies the agent evenly on the entire surface.

Nonetheless, the choice of either a bottle or can entirely depend on you. You want to keep the spray can or bottle at least 15 to 20 cm away from the fabric’s surface during application. Additionally, you want to apply a single layer of mist across the entire surface. You may, however, find spray options that require you to apply more than one layer.

  • Drying

When applied to your clothing or gear, waterproofing spray doesn’t dry instantaneously. Depending on the formula, different sprays have varying drying times. Thus, you want to consider the time when picking the right option to invest in as well.

Some of the best waterproofing sprays take about an hour or two to dry. However, others take as long as 48 hours. On average, waterproofing sprays designed for light use on clothing, shoes, and similar gear takes about 2 to 8 hours to dry up.

  • Washability

Waterproofing sprays are applied to clothing and gear to enhance their water repellency. Hence, it would be impractical to have a waterproofing formula that isn’t washable. But, some silicone-based coatings can easily be washed off by detergents. Therefore, you want to avoid these types of sprays. Alternatively, you can reapply the spray after every wash with a detergent.

  • Duration

The frequency at which you apply waterproofing spray depends on their composition and how often you use them. Generally, you should apply waterproofing spray at least once or twice weekly on light items such as clothing, shoes, bags, and tents during the wet season.

You don’t have to apply the spray as frequently on furniture covers since you won’t be taking them out to extreme weather. Likewise, during the dry seasons, you don’t have to apply the waterproofing spray as frequently. You only want to apply it from time to time to protect your gear from stains.
