How to waterproof horse blankets [A beginner’s guide]

Are you tired of your horse blankets getting soaked in the rain? Well, I’ve got some handy tips on how to waterproof horse blankets. Let’s saddle up and explore how you can keep horse blankets dry!

How do you waterproof a horse blanket?

Step 1: Clean the blanket up

Give your blanket a good scrub to get rid of any dirt or grime. Use a gentle detergent and warm water. Rinse it thoroughly and let it dry completely.

Step 2: Choose your waterproofing product

Now it’s time to pick the waterproofing product. There are two popular options: waterproofing sprays or wash-in treatments.

Sprays are great for spot treatments, while wash-in treatments cover the whole blanket.

Of course, if you prefer, you can also use waterproofing sprays to cover the entire blanket. Just keep in mind you might need a few cans to get the job done right.

Step 3: Apply your waterproofing product

If you’re using a waterproofing spray, shake the can well and hold it about 6 inches away from the blanket.

Start spraying evenly, making sure to cover all areas. Don’t forget the seams and stitching!

For wash-in treatments, fill a basin or tub with warm water and mix in the wash-in treatment.

Submerge the blanket and agitate it gently to ensure even coverage. Let it soak for the recommended time, then rinse and hang to dry.

Step 5: Check for missed spots

After the blanket is dry, inspect it closely to make sure there are no missed areas. If you find any, repeat steps 3 or 4.

Step 6: Test the results

Put your newly waterproofed blanket to the test! Pour a little water on different areas of the blanket and see if it beads up and rolls off.

If it does, you’ve successfully waterproofed your horse blanket.

To keep your blanket in top shape, reapply the waterproofing treatment periodically.

How long does a horse blanket stay waterproof?

No horse blanket stays waterproof forever. With proper care and maintenance, a high-quality waterproof horse blanket can stay effective for several seasons.

Over time and with use, the waterproofing of your blanket may decrease.

Rain, washing, and wear and tear can make your horse blanket less waterproof.

Keep an eye out for wet spots or water not beading up on the surface of your blanket. Regularly check for signs of water absorption.

Does washing horse blankets remove waterproofing?

Washing your horse blanket might mess with its waterproofing. Many blankets have a water-repellent coating called DWR on the outside.

Regular washing, especially with tough detergents, can wear off this coating.

To keep your blanket in top shape, use gentle detergents made for horse blankets. Don’t go overboard with washing—spot cleaning works too.

And here’s the kicker: After washing, you might need to reapply a waterproofing treatment or spray to bring back that water-repellent magic.

How often should you wash a horse blanket?

How often should you wash your horse blanket? It all depends on how dirty it gets and how often you use it. But as a rule of thumb, it’s best to wash your horse blanket when it’s actually needed.

Don’t worry about sticking to a strict schedule. Just keep an eye on its cleanliness and give it a good wash when it starts looking dirty or smelling funky.

Wondering when to wash your horse blanket? Here are some signs to look out for:


If you see visible dirt, mud, or stubborn stains, it’s a surefire signal that it’s time for a thorough cleaning.


Got a whiff of a persistent and unpleasant odor coming from your horse blanket? That’s a clear sign that it’s due for a quick wash.

Don’t let that funky smell linger any longer!

Sweat and moisture

If your horse has been sweating up a storm under the blanket or if the blanket has been drenched in rain, it’s crucial to give it a wash.

This will help prevent the nasty buildup of bacteria and mold.

Keep your horse and the blanket fresh and clean!

Seasonal changes

When a season comes to a close or when you’re switching to a different weight blanket, give your horse blanket a thorough wash.

This will help get rid of any built-up dirt and sweat that may have accumulated over time.

Keep that blanket fresh and ready for the next season or weight change!

What are waterproof horse blankets made of?

Waterproof horse blankets are built with three main layers: an outer shell, an inner lining, and insulation.

The outer shell, made from tough fabrics like nylon or polyester, keeps the blanket sturdy. It’s often treated with a waterproof agent or given a water-repellent finish.

Inside, the cozy inner lining offers comfort and insulation. Nylon, polyester, or fleece materials help retain warmth and wick away moisture.

For extra warmth during chilly times, there’s a layer of insulation. It can be made from synthetic fibers like polyester or natural materials like wool.

To keep the water out, high-quality blankets have sealed seams that prevent any sneaky leaks. And those handy closures—buckles, straps, or Velcro—make sure the blanket stays snug on your horse.

With these features, your horse stays dry and comfy, no matter the weather!
