How To Waterproof Horse Blankets

For a horse, being wet is no fun.

Not only does it make them feel miserable and cold, but they also lose their natural body heat very quickly when they are wet.

There are many ways to keep your horse dry in the rain or snow, but one of the most important things you should do is waterproof their blanket.

Here’s how to do it:

1. Wash the blanket with detergent and hot water

it is important to ensure that the blanket is clean before you waterproof it, as dirt could compromise the effectiveness of the waterproofing agent and may create ‘waterproofing blind spots’.

This can happen when dirt falls off the blanket leaving behind a small patch that will not have been covered by waterproofing spray.

2. Apply a good quality fabric protector to the blanket

Scotchguard is a good choice of waterproof spray.


However make sure that whatever fabric protector you use it is appropriate for the fabric your horse’s blanket is made from.

For example a polyester blanket would not be suitable for waterproofing with a fabric protector which is designed to work on cotton.

Also be aware that some sprays are breathable and some aren’t.

A fabric protector that is breathable is preferable as this reduces sweating.

3. Apply the spray

Most waterproof fabric sprays come in aerosol form and can be applied by spraying onto your horse’s blanket from about one meter away.

This should be done outdoors or in a well ventilated area. Do not inhale the spray and avoid getting it onto your skin.

Coat the whole surface with an even spray.

We recommend you use multiple coats, however you need to leave 24 hours between each coat so if you only have time for one coating then apply the spray more generously.

4. Allow plenty of time to dry

To ensure the fabric protector will work you need to give it sufficient time to dry.

Give it at least 24 hours to dry out before you use it.

As mentioned above we do recommend multiple coats for the best results.

Three coats is optimal however you will need to leave it for 24 hours between each coat.

Be aware some sprays dry better in the sun, others dry better in shaded areas so check the instructions before you leave you dry your horse blanket.

5. Test It

Test your waterproof horse blanet by pouring a small amount of water on top and checking for any seepage or leakage through the material.

Pay close attention to cracks in seams as these are the places where leaks are most likely to occur.

You can also try out its rain protection abilities outside in the rain (or under a sprinkler!).

If no leaks are found from either process- congratulations – your horse blanket Is waterproof!
