Tips on how to Waterproof a Horse Rug Effectively
If you want to rug your horse, learning how to waterproof a horse rug is important if you don’t want to constantly buy new rugs. Waterproof rugs ensure your horse stays dry and comfortable, even in challenging weather conditions.
To help you, we’ve put together this handy guide about how to waterproof a horse rug. It will walk you through the step-by-step process of professionally waterproofing your horse rug, using techniques and products trusted by equestrian experts.
Is Your Rug The Right Type To Re-Waterproof?
Note – not all horse rugs can be re-water proofed. Synthetic rugs for example have a waterproof membrane on the inside of the fabric but the fabric itself is meant to breath.
In fact, re-waterproofing synthetic horse rugs with waterproofing products intended for canvas can interfere with the breathability of the rug. Similarly, cotton and similar types of rugs should not be water proofed and doing so could destroy the fabric. However, if you have a good quality canvas rug, it will usually re-waterproof very well.
What You’ll Need To Re-Waterproof A Horse Rug
A clean horse rug suitable for re-waterproofing (see above re synthetic rugs etc) AND the following items –

Waterproofer for horse rugs (preferably non-toxic and water-based)
A soft-bristle brush
A clean cloth
Well-ventilated workspace
Gloves, protective eyewear
Step 1 – Preparing The Area To Reproof Horse Rug
Choose a well-ventilated and properly lit area for your work. Lay down a protective covering to prevent any potential mess, especially if you’re doing this on the driveway or patio at home! If desired, wear gloves and protective eyewear to safeguard your skin and eyes.
Step 2 – Clean The Horse Rug
Make sure your horse rug is thoroughly clean before applying any waterproofing solution. Use a soft-bristle brush to remove dirt, debris, and loose hair. A clean rug allows for better penetration of the waterproofing solution.
Step 3 – Choose An Appropriate Waterproofer For Horse Rugs
In addition to the traditional horse rug waterproofing solutions, there are several other horse rug waterproofing products available in the market. These products offer different formulations and application techniques to cater to various preferences and requirements.
When selecting a waterproofer for horse rugs, consider factors such as the rug’s fabric, the climate, the application method you’re using, and any specific features you’re looking for (such as UV protection or mould resistance). Always follow the manufacturer’s instructions for application and maintenance to ensure the best results.
Waterproofing Wax For Horse Rugs
Apply these solid waterproofing waxes to horse rugs by rubbing or melting the wax onto the fabric. They then create a protective barrier that repels water while allowing the fabric to breathe. These waxes can be particularly effective for heavy-duty rugs and those used in harsh weather conditions.
Spray-On Horse Rug Waterproofing
Similar to traditional waterproofing solutions, spray-on water-proofing products come in spray bottles for convenience and easier application. Evenly spray onto the rug’s surface and allow to dry. Some formulations might have added features like UV protection or mould resistance.
Horse Rug Waterproofing Paste or Cream
Thicker products, such as waterproofing pastes or creams, are applied to the rug using a brush or cloth. They provide a more concentrated waterproofing layer and can be useful for targeting specific areas, such as seams and stitching.
Nikwax® and Other Specialised Brands
Brands like Nikwax® offer specialised products designed for outdoor gear, including horse rugs. These environmentally friendly options are often not only waterproof but also eco-conscious. Such products often come with detailed instructions for application so be sure to follow them closely for best waterproofing results.
Waterproofing Wash-In Products For Horse Rugs
These products are typically used during the rug washing process. You add the waterproofing solution to the washing machine along with the rug. The heat and agitation of the washing machine help distribute the waterproofing agent evenly across the fabric.
This method ensures thorough coverage but might require specific washing machine instructions. Note – it’s NOT recommended doing this in your home washing machine unless you have one specifically for horse rugs!
Silicone-Based Waterproofing Products For Horse Rugs
Silicone-based waterproofing sprays or liquids create a hydrophobic barrier that repels water effectively. They are suitable for a variety of materials, including horse rugs. However, it’s important to ensure compatibility with your rug’s fabric. Also note that they can affect the fabric’s breathability if not specifically designed for horse rugs.
DIY Waterproofing Mixes For Horse Rugs
For those who prefer a DIY approach, there are various recipes available online for creating your own waterproofing solutions using natural ingredients like beeswax, lanolin, and natural oils. These can be a great option if you want more control over the ingredients used.
Step 4 – Test the Solution (Optional but Recommended)
Before applying the waterproofing solution to the entire rug, perform a patch test on a small, inconspicuous area. This test ensures compatibility with the fabric and helps you evaluate the desired waterproofing effect.
Step 5 – Apply The Waterproofing Solution
Follow the directions for use supplied by the manufacturer of the waterproofing product. Generally, though – if using a spray or liquid, shake the waterproofing solution well before opening. Start at one end of the rug and work your way systematically across its surface. Apply the solution evenly as per instructions, focusing on areas prone to moisture infiltration, such as seams and stitching.
Step 6 – Ensure Even Coverage
Use gentle, overlapping strokes to ensure even coverage. Avoid over saturating the fabric, as excess solution may affect the rug’s breathability. Remember that proper application directly impacts the longevity of the waterproofing effect.
Step 7 – Drying Time
Allow the rug to dry thoroughly in a well-ventilated area, following the manufacturer’s instructions. This step is crucial, as insufficient drying may compromise the effectiveness of the waterproofing solution.
Step 8 – Assess The Waterproofing (Optional)
After the rug has dried, assess its waterproofing by conducting a water droplet test. Sprinkle a few drops of water onto the rug’s surface. If the water beads up and rolls off, the waterproofing is successful. If the water is absorbed or penetrates the fabric, consider applying another coat of the waterproofing solution.
How often should you re-waterproof a horse rug?
A quality annual waterproof treatment should last a season so, essentially, you could re-treat a turnout rug for several seasons of use and still save money because you don’t need to buy a new one. However, the frequency with which you need to waterproof your horse rug will depend on a few factors, including:
The type of horse rug
Some rugs are more waterproof than others.
The amount of use the rug gets
A rug that is used frequently in wet conditions will need to be waterproofed more often than a rug that is only used occasionally.
The climate
If you live in a wet climate, you will need to waterproof your rug more often than if you live in a dry climate.
Troubleshooting Re-Waterproofing A Horse Rug
If the rug is not waterproof after following these instructions, the fabric may not be intended for use as a waterproofed item. In this case, you may need to purchase a new rug.
If the rug is waterproof but it still leaks water, it may be because the stitching or seams are not tape seamed. This can allow water to penetrate the rug even if the fabric itself is waterproof. You may also not have applied the waterproofing product evenly enough, and missed small areas.
