Understanding Waterproofing: What It Means and When to Reapply

A blanket labeled “waterproof” doesn’t mean it will stay that way forever. Waterproofing is both science and maintenance—and knowing when to reapply is key to keeping your horse dry.

Not all “waterproof” claims are created equal — and understanding what those words mean for your horse’s blanket can make the difference between a cozy turnout and a soggy, uncomfortable mess. Waterproof fabrics are designed to repel water while still allowing airflow, keeping horses dry without trapping sweat.

Over time, however, dirt, sweat, and repeated washings can reduce a blanket’s effectiveness. If you notice water starting to bead less or soak in faster, it may be time to reproof your blanket. Reproofing sprays and washes are easy to use and can extend the life of your investment by seasons.

Pro tip: spot-clean regularly and wash only when necessary. Always follow manufacturer care instructions, as harsh detergents can strip the waterproofing layer. With a little maintenance, your horse can stay warm, dry, and comfortable no matter what winter throws your way.

How Waterproofing Works

• Fabrics are treated with coatings that repel water.

• Durable outer shells (like ripstop) help shed moisture.

Signs Waterproofing Is Wearing Off

• Dark spots where water soaks in.

• Fabric feels heavy and damp instead of beading water.

• Horse’s coat is wet underneath after turnout.

How to Reapply

• Clean blanket first—dirt blocks waterproofing.

• Use equine-safe sprays or wash-in treatments.

• Let gear fully dry before use.
