Buffing leather is the process of lightly sanding or abrading the surface of an animal hide to change its texture, remove imperfections, or create an entirely different type of leather product. It’s one of the most common steps in leather manufacturing, used to produce everything from velvety nubuck to smooth corrected-grain handbags. Depending on which side of the hide gets buffed and how aggressively, the results look and feel dramatically different.
How the Buffing Process Works
At its core, buffing means rubbing the leather surface against an abrasive material, typically sandpaper wrapped around a revolving cylinder. In a tannery, this is done with industrial machines that allow precise control over pressure and speed. For smaller-scale leatherworkers, the same principle applies with handheld sandpaper ranging from coarse 120-grit all the way up to ultra-fine 2000-grit for polishing.
The grit matters. Coarser grits remove more material and create a more noticeable texture change, while finer grits smooth and polish the surface. A leatherworker finishing edges on a belt or wallet, for example, might progress through several grits from medium to polishing grade to achieve a glossy, candy-like edge.
Why Manufacturers Buff Leather
Buffing serves three distinct purposes depending on the goal: creating a napped texture, hiding surface damage, or preparing leather for a new finish.
During their lives, cattle pick up all kinds of skin damage from biting flies, ticks, lice, disease, and manure exposure. These leave scars and blemishes on the grain surface that would be visible in a finished product. Buffing lets manufacturers sand away those imperfections, then apply a pigmented finish over the top to create a uniform, clean-looking surface. This is how corrected-grain leather is made, and it’s the most common reason for buffing in mass production.
The other major reason is to deliberately create a soft, fuzzy texture called “nap.” When you buff the outer surface of a high-quality hide, the tightly packed fibers get disrupted and stand up, producing the velvety feel found in nubuck leather. This isn’t about hiding flaws. It’s about transforming a smooth surface into something that feels completely different to the touch.
Nubuck, Suede, and the Side That Gets Buffed
The biggest distinction in buffed leather comes down to which side of the hide is sanded. A hide has two usable sides: the grain (outer) side, which was exposed to the world while the animal was alive, and the flesh (inner) side.
Nubuck is made by buffing the grain side of a top-grain hide. Because the grain surface has a tighter, denser fiber structure, the resulting nap is finer and more uniform than suede. It retains much of the strength of the original hide while gaining that characteristic velvety softness.
Suede takes the opposite approach. After the hide is split into layers, the inner flesh side of the lower split is buffed to raise a plush nap. The fibers on the flesh side are looser and longer, which gives suede its distinctly soft, almost fuzzy texture. It’s also why suede is generally less durable and more prone to staining than nubuck, even though both look similar at first glance.
Corrected-Grain Leather
Corrected-grain leather is the most commercially significant result of the buffing process. The International Union of Leather Technologists defines it as leather from which the grain layer has been partially removed by buffing to a depth governed by the condition of the raw material, then rebuilt with applied finishes.
In practical terms, this means the natural surface of the hide is sanded down enough to eliminate visible blemishes, then coated with a heavily pigmented paint layer that creates the final look. The new surface can be embossed with an artificial grain pattern to mimic the appearance of full-grain leather. This is why corrected-grain products often look perfectly uniform compared to full-grain leather, which retains natural variations.
The tradeoff is that buffing away the grain layer also removes some of the leather’s natural breathability and develops a surface that’s more reliant on its finish coat for appearance and protection. Corrected-grain leather is less expensive than full-grain because it can be made from lower-quality hides that would otherwise be unusable for premium products.
Snuffing: A Lighter Version of Buffing
Not all buffing goes deep. A related technique called “snuffing” involves very lightly buffing the grain surface, typically with fine carborundum paper on a revolving cylinder. Snuffing sits between a gentle surface treatment and the more aggressive removal involved in corrected-grain work. The result is a leather described as “snuffed,” with a subtle texture change that softens the surface without significantly removing material. You’ll sometimes see this on shoes and bags where a slightly matte, textured feel is the goal rather than the high nap of nubuck.
What Happens After Buffing
Buffed leather rarely stays as-is. The treatment that follows depends on what type of product is being made.
For corrected-grain leather, the buffed surface gets coated with pigmented finishes that build up a new visual surface. These coatings provide color, protection, and often an embossed grain pattern. The finish is what you actually see and touch in the final product.
For nubuck and suede, the approach is different. The nap itself is the point, so heavy coatings would defeat the purpose. Instead, these leathers may receive light conditioning treatments. Beeswax or carnauba wax can be applied and buffed to add water resistance and a subtle sheen to smooth leathers. For napped leathers, protective sprays that don’t flatten the fibers are more common.
Leatherworkers finishing edges on cut pieces use buffing as a final polishing step. After sanding through progressively finer grits, they often seal the edge with beeswax or paraffin wax, then buff again with a soft cloth or canvas to create a smooth, glossy finish that resists moisture and fraying. Glycerin can also be worked into the leather and buffed with a cloth to produce a lustrous surface shine on smooth-finished pieces.
Buffing in Leather Care
Outside of manufacturing, buffing is also something you do to maintain leather goods you already own. Polishing a pair of leather shoes involves applying wax or cream and then buffing with a soft cloth or brush to bring up a shine. This type of buffing isn’t removing material. It’s redistributing the polish across the surface and building up thin, even layers that protect the leather and reflect light.
The principle is the same as in manufacturing: controlled friction changes the surface. The difference is just scale and intensity. A tannery uses industrial machines and sandpaper to reshape the hide itself. You’re using a horsehair brush and shoe cream to maintain the finish on top.
