Ugg boots are made from sheepskin and suede, which are naturally delicate materials. They soak up water and stains quickly, and improper care can ruin them permanently. The good news is that you can protect them at home with the right spray and a little patience. Here is exactly how to waterproof your Ugg boots without damaging the leather or the fleece lining.

Why You Shouldn’t Skip Waterproofing

One rainy walk can leave dark water marks on your Uggs. Worse, water can cause the sheepskin to shrink and lose its softness. The fleece inside can also become stiff and smelly if it gets soaked. Waterproofing creates a barrier that repels water and dirt before they ever touch the material.

You should treat a new pair of Uggs before you wear them outside. But if you already own a pair, it is not too late. Just make sure the boots are clean and completely dry before you start. Applying spray to dirty or damp boots will trap moisture and grime inside the fibers.

Step 1: Clean Your Boots First

Waterproof spray will not work on dirty boots. It will just seal the dirt into the suede. Start by brushing the boots with a suede brush to remove loose dust and mud. Use a soft, dry cloth to wipe down the surface.

For stubborn stains, use a dedicated suede eraser or a small amount of white vinegar on a cloth. Do not use water to clean your Uggs. Water is the enemy here. Let the boots air dry completely after cleaning. This can take 24 hours, so plan ahead.

Step 2: Choose the Right Waterproof Spray

You cannot use just any waterproofing product. Many sprays contain silicone or wax that will ruin the soft, napped texture of sheepskin. You need a spray made specifically for suede and sheepskin.

Look for a product that says “suede protector” or “sheepskin guard” on the label. Ugg Australia sells its own brand, but you can also use a high-quality suede protector from brands like Nikwax or Collonil. Avoid mink oil and heavy waxes. They will darken the leather and flatten the suede nap permanently.

Step 3: Apply the Spray Evenly

Work in a well-ventilated area. Place newspaper on the floor and put your boots on top. Hold the spray can about 15 to 20 centimeters away from the boot. This distance is important. Too close, and the spray will soak the material too much. Too far, and it will not cover the surface evenly.

Use a sweeping motion to cover the entire boot. Do not miss the seams or the area near the sole. These are the spots where water sneaks in first. Apply a thin, even coat. Do not soak the boots. You want a light mist, not a wet layer.

Step 4: Let It Dry and Apply a Second Coat

Let the first coat dry completely. This usually takes 1 to 2 hours. Do not speed up the process with a hairdryer or heater. Heat will shrink the sheepskin and ruin the shape of the boot. Just let them sit at room temperature.

Once dry, apply a second coat using the same technique. Two thin coats are much better than one thick coat. The second layer fills in any spots you missed and gives you stronger protection. After the second coat dries, give your boots one final brush with the suede brush to restore the soft nap.

How Often Should You Waterproof?

For everyday wear, you should waterproof your Uggs every 4 to 6 weeks. If you wear them daily in winter, do it once a month. If you only wear them occasionally, twice a season is enough.

You will know it is time to reapply when water starts beading on the surface instead of rolling off. Another sign is a slight darkening of the suede when you walk on wet ground. Do not wait for a full soak before you reapply. Prevention is always easier than repair.

What to Do If Your Uggs Get Wet

Mistakes happen. If your Uggs get caught in the rain or step in a puddle, act fast. Use a dry towel to blot the excess water. Do not rub. Rubbing will push the water deeper into the fibers and raise the nap unevenly.

Stuff the boots with dry paper towels to help them hold their shape and absorb moisture from the inside. Let them air dry away from direct heat. Do not place them near a radiator or in front of a fireplace. Once dry, brush them to restore the texture, then reapply your waterproof spray.

Frequently Asked Questions

Can I use scotchgard on my Ugg boots?

No. Standard Scotchgard is designed for fabric and can contain silicones that ruin sheepskin. It can make the suede stiff and change the color. Always use a spray that is labeled for suede or sheepskin.

Does waterproofing change the color of my boots?

A good suede protector should not change the color. But some sprays can slightly darken the material when wet. This is normal and the color should return to normal once dry. To be safe, test the spray on a small hidden area like the inside heel before you do the whole boot.

Can I waterproof my Uggs in the washing machine?

Never put Uggs in the washing machine. Machine washing will ruin the sheepskin, warp the shape, and destroy the glue that holds the sole on. Waterproofing is done by hand with a spray only.

How long does waterproof spray last on Uggs?

Most quality suede protectors last 4 to 6 weeks with regular wear. If you wear your boots only indoors or on dry days, the protection can last a few months. Reapply when water no longer beads on the surface.
