How to Seal Leather After Dyeing or Painting

To seal leather, let the dye or paint dry completely, buff off any loose color, then apply a top finish in light, thin coats and let each coat dry before the next. Acrylic finishes give a glossy look, and wax or matte finishes keep the leather looking more natural. On painted leather, let the last coat cure for 24-48 hours before you use the item.

This guide is part of our leather dyeing and finishing series. It covers the sealing step only. For the color itself, see how to dye leather or how to paint leather.

Key takeaways- Seal only after the color is fully dry and buffed until no color comes off on the cloth.- Thin coats beat one heavy coat. Heavy finish can look cloudy, and rubbing hard can lift paint.- Not every finish resists water. Fiebing's says its wax-based Leather Balm doesn't.- Even sealed, dyed leather can still transfer some color, so high-contact items get an extra coat.- Test the finish on scrap or a hidden spot first.

Which leather sealer should you use?

Pick the finish by the look you want and whether the item will get wet. The table lists finishes whose makers publish what they do.

A paint maker, Golden, lists acrylic, oil, wax, silicone and polyurethane topcoats as options over paint, but says to check each one is compatible with acrylics first.

The store we link to, Leather Collection, doesn't sell sealers, dyes or paints. For the finished garments it does sell, its care page recommends a water and stain repellent, tested on a hidden area first.

Do you need to seal leather?

On dyed leather, sealing is a separate final step that helps stop the color rubbing off. Tandy, a leather supplier, says sealing locks in dye and adds moisture protection. Even then, dye can still transfer to clothing or skin, which is why belts, bags and shoes get an extra coat.

On painted leather, the finish is optional if the leather was prepped well, according to The Leather Guy, a leather supplier. It adds protection against scratches and moisture.

Safety before you open the bottle

We couldn't find a current safety data sheet (SDS) for the finishes in the table on their makers' pages, so read the label and ask the maker for the SDS for the exact product you buy.

• Open a window or run a fan. The EPA advises extra ventilation when you use paints and solvents, and following label precautions at a minimum.
• Wear gloves when handling dyed leather, since buffing lifts loose dye.
• If you strip an old finish first, the deglazer is mostly acetone and alcohol. According to NIOSH, acetone has a flash point of 0°F (-18°C), so keep it away from flames.
• Store finishes where they won't freeze. Resolene won't work properly if frozen.

Tools and materials

How to seal leather, step by step

Step 1: Test the finish on scrap or a hidden spot

Seal a scrap piece or a hidden area first, especially over new dye, antique, oil, paint or older finished leather. Judge the sheen and color once the test is dry.

Step 2: Let the color dry completely

Sealing comes only after the color has dried completely. Dharma Trading's dye guide lets dyed items dry overnight. For paint, let each coat dry fully before sealing. How long dye needs depends on the product and the room; see how long leather dye takes to dry.

Step 3: Buff until no color comes off

Rub the dyed surface with a clean, dry cloth until no more color comes off. Fiebing's also says to buff off unabsorbed dye once it's dry and before you seal. Skip this on painted leather, where rubbing can lift the paint.

Step 4: Check that the surface will take a finish

Don't put a finish over leather that has been waxed or treated with silicone. Make sure the surface is dry and free of dust.

Step 5: Thin the finish only if the maker says so

Some water-based finishes can be thinned. For Resolene, the directions give 10-15% water, up to a maximum of 30% depending on temperature and sprayer, and warn that more water gives less of a seal. Follow your own product's label, because others differ.

Step 6: Apply a light, even coat

Wipe the finish on with a damp sponge, using a light touch. Work it over edges, seams and tooled lines too. On paint, use thin, even coats with a clean brush or cloth, because heavy or aggressive application can make the paint run or rub off.

Step 7: Let it dry, then add coats

Let each coat dry before the next so the finish builds evenly and doesn't look heavy or cloudy. Build up in light coats, adding an extra one on belts, bags and shoes.

Step 8: Let it cure before use

On painted leather, let the last coat cure for 24-48 hours, and give it more time if it still feels tacky or soft. Then do a rub test with a white cloth on a hidden spot.

Sealing painted leather

Use a finisher made for, or checked against, acrylic paint. The Angelus finisher comes in matte, satin, normal and high gloss. For a flatter look, Angelus says you can add its Duller, but no more than 0.5 oz to a 4 oz bottle. The Leather Guy says Fiebing's Resolene also works over paint.

Brush it on thinly and gently. If you're still choosing a paint, see what type of paint to use on leather.

In this Weaver Leather Supply video, Daniel Reitz explains why rubbing a liquid sealer over paint can lift it, and seals painted pieces with aerosol finishes instead: Fiebing's Leather Sheen for water resistance, then a clear matte spray to cut the shine. He sprays from 10-12 inches, starting and stopping each pass off the piece, and builds up many light coats. Aerosols aren't covered by the brush-on steps above, so read the can's label and spray only with good ventilation.

Sealing for water resistance

Two of the finishes above, Resolene and Leather Sheen, are sold as water-resistant finishes. Leather Balm with Atom Wax isn't. None of these makers calls its finish waterproof.

For faux leather, Collonil says a waterproofing treatment helps keep water and dirt from soaking in. See how to protect faux leather.

Common mistakes

Sealing a jacket or bag you bought?

Factory-finished garments are a different job. Leather Collection doesn't sell sealers. For its jackets and other finished leather, follow the Leather Collection care instructions, which recommend a water and stain repellent and a hidden-area test.

Quick answers

What is a good clear sealer for leather?

It depends on the look. Acrylic finishes such as Resolene dry glossy and water-resistant. Wax finishes look more natural, but Fiebing's Leather Balm isn't water-resistant.

What do you use to seal paint on leather?

Use an acrylic finisher that's compatible with your paint, such as the one sold by your paint's maker. Apply thin, gentle coats and let it cure 24-48 hours.

Should you oil leather before dyeing?

That's a dyeing question, not a sealing one. See how to dye leather. To darken leather with oil instead, see how to darken leather.
