Is Nubuck Waterproof? How to Protect It
It is the question everyone asks before buying nubuck boots or a nubuck jacket: is nubuck waterproof?
The short answer is no, standard nubuck is not waterproof. Its soft, sanded surface absorbs water. But nubuck can be made water-resistant with the right spray, and some nubuck is specially treated during tanning to be waterproof. This guide explains the difference, how to protect your nubuck, and what to do if it gets soaked.
Is nubuck waterproof or water-resistant?
Here is how the different types compare:
| Type | Water behaviour | Typical use |
|---|---|---|
| Standard nubuck | Absorbs water, can spot and stain | Fashion shoes, sneakers, bags, jackets |
| Nubuck + protector spray | Water-resistant: light rain beads off for a while | Everyday shoes and bags |
| Oiled or waxed nubuck | Naturally more water-resistant | Work boots, casual boots |
| Waterproof nubuck (treated in the tannery) | Strongly water-repellent through the leather | Hiking and outdoor boots |
| Nubuck boot with waterproof membrane | Waterproof (the membrane keeps water out) | Hiking and work boots |
So when a boot is sold as "waterproof nubuck", the waterproofing usually comes from a tannery treatment, a membrane inside the boot, or both, not from the nubuck alone.
Why standard nubuck absorbs water
Nubuck is top-grain leather whose surface has been sanded to create a short, velvety nap. Sanding opens the tight surface of the leather, so water can enter more easily than on smooth leather. (Read more in what is nubuck leather.)
When water gets in, three things can happen:
- Water spots and rings, where the wet area dries with a visible edge.
- A flattened, stiff nap, as fibres stick together when they dry.
- Salt lines in winter, when road salt dissolves in the water and dries on the surface.
None of this means nubuck cannot handle rain. It just means it needs protection.
How to waterproof nubuck: step by step
You cannot make standard nubuck 100% waterproof at home, but you can make it highly water-resistant.
1. Clean first
Spray only on clean, dry nubuck. Brush off dust and use a nubuck eraser on marks. If you need a deeper clean, follow our nubuck cleaning guide and let it dry fully.
2. Choose the right spray
Use a water and stain repellent made for suede and nubuck. Modern sprays often use fluorine-free or "nano" technology that coats each fibre without clogging the nap.
Avoid:
- Waxes, oils and mink oil on standard nubuck. They darken the colour and flatten the nap. They are fine on oiled nubuck only.
- Heavy silicone sprays that leave the surface sticky or shiny.
3. Apply in a ventilated space
Work outdoors or near an open window. Shake the can and hold it 15–20 cm from the leather.
4. Spray evenly
Apply a light, even coat over the whole item, including seams and the area where the upper meets the sole. Do not soak it. Several light coats are better than one heavy one.
5. Let it cure
Leave it to dry for at least a few hours, ideally overnight. Many sprays only reach full strength after curing.
6. Add a second coat
Apply a second light coat and let it dry again.
7. Brush the nap
Once dry, brush gently to restore the soft texture.
Test first: some sprays darken light nubuck slightly. Try a small hidden area before spraying the whole item.
How often should you reapply?
Protection wears off with use, rubbing and cleaning. As a guide:
- Wet or snowy seasons: every 2–4 weeks for shoes and boots worn often.
- Dry seasons: every 1–2 months.
- Bags and jackets: a few times a year, or after cleaning.
A quick test: sprinkle a few drops of water on the surface. If they bead and roll off, the protection is working. If they soak in and darken the leather, it is time to reapply.
What to do if nubuck gets soaked
Even protected nubuck can get soaked in a downpour or deep snow. Act like this:
- Blot, don't rub. Press a clean towel on the surface to remove excess water.
- Remove laces and insoles from shoes and boots.
- Stuff with paper (plain paper or newspaper) to absorb moisture from inside and keep the shape. Change the paper every few hours.
- Dry at room temperature. Never use a radiator, heater, hair dryer or direct sun. Heat shrinks and cracks leather.
- Even out marks. If a water ring appears, lightly dampen the whole panel and let it dry evenly.
- Brush once fully dry to lift the nap.
- Reapply protector.
Removing salt stains
Mix equal parts white vinegar and water. Dab it over the salt line, then lightly over the whole panel, let it dry and brush. Repeat if needed.
If nubuck feels stiff after drying
Flex the leather gently with your hands, brush it, and if needed use a light conditioning spray made for nubuck.
Should you choose nubuck for rainy climates?
Nubuck can work well in wet weather if you choose the right type:
- For everyday city shoes, standard nubuck with a good protector spray is fine for light rain.
- For regular rain, snow or hiking, choose oiled nubuck or waterproof nubuck, ideally with a waterproof membrane.
- For very heavy use with minimal care, smooth full-grain leather is easier. Our comparison of nubuck vs suede and full-grain leather explains the trade-offs.
If you are a brand choosing materials for outdoor products, ask your manufacturer for waterproof-treated nubuck and test samples. Our nubuck buyer's guide covers what to ask.
Frequently asked questions
Is nubuck waterproof?
Standard nubuck is not waterproof. It becomes water-resistant with a protector spray, and specially treated nubuck or boots with a waterproof membrane can be fully waterproof.
Can nubuck get wet?
Yes. It will survive rain, but dry it slowly at room temperature and brush it afterwards to avoid spots and a stiff nap.
Does water ruin nubuck?
Not usually. Water can leave marks or stiffness, but these can normally be fixed by evenly dampening the panel, drying it slowly and brushing.
Is nubuck more water-resistant than suede?
Slightly. Nubuck's tighter grain absorbs water more slowly than suede, but both need protection.
Can I use mink oil or wax on nubuck?
Not on standard nubuck. They darken it and flatten the nap. They are suitable only for oiled or waxed nubuck.
Do waterproof sprays change the colour of nubuck?
Some can darken light shades a little. Always test on a hidden area first.
Are Timberland-style nubuck boots waterproof?
Many outdoor nubuck boots use waterproof-treated leather plus sealed seams or a membrane. Check the product description: "waterproof" means it is designed for it, while plain "nubuck" usually is not.
Conclusion
Standard nubuck is not waterproof, but it does not have to fear the rain. Clean it, protect it with a nubuck spray, reapply regularly, and dry it slowly if it gets wet. For real outdoor conditions, choose oiled or waterproof nubuck.
