What Should You Use to Waterproof Horse Blankets?
The product you choose is very important. There are two main types of waterproofing products, spray on ones and in-wash products. You want UV resistant, fabric protective products that will last in cold, wet weather.
Pay attention to the type of fabric the product is designed for; some are made for nylon, cotton, leather, etc. Other products are breathable, while some are not. You want to look for a breathable product that will work with the fabric of your horse blanket (usually a nylon blend).
Some equestrian brands and blanket manufacturers make products specifically formulated for horse blanket waterproofing, but if you can’t find those, check online or at your local camping and outdoor stores. They usually have heavy duty waterproofing sprays that work just as well as any horse-specific product.
When Should I Waterproof My Horse’s Blanket?
If you notice wetness seeping through the outer layer of your blanket or that it’s soaked through, you should re-waterproof it. You might also notice water droplets no longer roll off the outer layer of the blanket, which is an early sign that your blanket exterior is no longer water repellent.
Seasons with moderate weather are best, like late spring and early fall, either before or after the winter. You don’t want to try waterproofing horse blankets in below zero weather, so be sure you do it beforehand.

Can I Waterproof Horse Blankets Indoors?
Depending on the product you choose, you may have to do it outside. In-wash products can be used indoors in your washing machine, but any time you decide to use a spray on product, you should do it outside. Make sure that you use the product on a warm day to help it adhere to the fabric, and that your blanket is clean before starting.
If the blanket is dirty, the product won’t stick to the fabric as well and it won’t last. That being said, be mindful of household detergents as some can damage the fabric of your horse blanket, and remove the leg straps before washing.
The best thing you can do it apply multiple coats of your product of choice to ensure full coverage. If you have to do it indoors, try to do it in an open space (like a garage, or well-ventilated room), and wear a mask and gloves.

Using In-Wash Products on a Horse Blanket
These products don’t tend to work as well as spray on coatings, but they’re more convenient since they can be used indoors. If you have to use an in-wash waterproofing product on your blankets, apply the solution on a sponge and spread it on the blanket evenly. Based on the manufacturer instructions, you might need a few coats.
Usually a warm wash setting is best to set the protective coating, but always check the label. Most require that you hang the blanket to dry after applying the product.
