How Long Does Waterproofing Spray Last?

Most waterproofing sprays available on the market can last up to four weeks. The water repellent coat will eventually wear off and you’ll need to apply a new coat after a few weeks.

Of course, if you wear your waterproof clothing only once or twice a week, then the waterproofing spray will last longer.

How long your water repellent spray actually lasts depends on a variety of factors that may include but are not limited to: the number of wears, the weather conditions, the quality of the spray, the quality of the fabric your clothes are made of and so on.

Shoe waterproofing sprays don’t last as long as water repellent solutions for clothes. On average, waterproof sprays for shoes are effective for 15 days. Again, this largely depends on how much or little you wear your shoes.

More specifically, if you wear them twice a week, then the liquid proof spray will last for a month. On the other hand, if you wear your shoes in harsh weather conditions, you need to apply a new spray coat after two weeks or so.

LiquidProof water repellent spray lasts for years

LiquidProof is an interesting waterproofing spray that uses nanotechnology to bond fibers resulting in years of protection. The formula is based on silicon dioxide particles that create a microscopical barrier against liquids. Water, oil and other types of liquids will simply bead up and roll off without seeping through.

Always add two layers of waterproofing spray

What I always do is make sure to add two layers of water repellent spray on my outdoor clothes and footwear. I first clean the pieces of clothing and the footwear that I’m going to apply the spray on and then carefully apply the first coat.

Then, I let my outdoor apparel dry on my porch for 30 minutes. I then apply the second coat of water repellent spray and let my clothes and boots dry overnight.

This ensures that the two waterproofing layers I applied are completely dry and the water repellent coat is as efficient as possible.

Waterproof spray should be applied in well ventilated areas. I, for one, do it on my porch. If you have a backyard, I suggest you carry out the process there. Waterproofing sprays can potentially be toxic for both pets and humans.

In order to apply an even coat, the best approach is to hold the spray in one hand and rotate your pieces of clothes and your shoes with the other hand. Make sure to adjust the angles whenever necessary in order to spray the whole surface.

Frequently asked questions

1. How long does waterproofing spray take to dry?

Most waterproofing sprays should dry in 30 minutes. Then you can apply a second coat to ensure your outdoor gear is weather resistant. Let the two coats dry overnight and the next day your waterproof clothes and shoes are ready to use.

Allowing your clothes and shoes to dry overnight before exposing to the elements ensures they’ll keep you dry and won’t crack.

2. How often should I waterproof my shoes/clothes?

You should spray you boots and shoes every 2-4 wears in the winter, especially if you exposed your footwear to rain, snow and mud. Sometimes, you may need to repair the waterproof coat after you spent the whole day in the open, walking through inches of snow or you stepped into too many puddles.


As you can see, most waterproofing sprays can last for up to 4 weeks. Bad weather conditions and intense usage significantly reduce their efficiency.

New solutions like LiquidProof can last up to a few years but can only be used on certain pieces of outdoor gear.
