REPAIRING LEATHER

PREPARING LEATHER FOR REPAIR

As with preparing leather for re-colouring, the most important thing in preparing leather for repair is to make sure it is as clean as possible.

Any dirt, grease, polish, glue, dye transfer or other contaminants will mean that the glue, filler or dye may not properly adhere to the leather, and stains may draw be drawn up from the leather into the new layer of dye. If you suspect there is any dye transfer on the leather, use GT14 Safety Solvent Cleaner first.

To clean the leather, you will need to clean the entire leather panel using GT12 Intensive Cleaner or GT15 Gentle Cleaner using a Nail Brush followed by a clean, damp Cotton Cloth. You will then want to wipe the panel with GT18 Leather Degreasant & Fabric Cleaner, or for heavier grease stains, use GT20 Hair & Hand Grease Remover – a powerful gel that dries to a powder in one minute that can be vacuumed away, drawing grease out of the leather in the process. GT20 Hair & Hand Grease Remover will not remove colour unless the damage is significantly aged – in which case the colour is likely to have already been compromised.

The leather panel should now be prepared for your leather repair, although a primer should be used prior to re-colouring. For more information on priming, see our priming for re-colouring advice page.

LEATHER AND VINYL WELD LARGE CUTS, RIPS AND HOLES

If your leather or vinyl has been damaged with a large cut, rip or hole, it’s best to repair the damage as soon as possible before it gets worse. The Liquid Leather Leather and Vinyl Weld system is probably the easiest and most effective method of making these repairs, and it has also proven to be extremely strong and durable, often lasting the life of the leather.

The Liquid Leather Leather and Vinyl Weld system comprised of using a Teflon Sheet (cut to size from 12cm x 24cm sheets), Leather & Vinyl Weld Backing Fabric and Leather & Vinyl Weld/Replicator, which is heat cured with a Thermal Sealing Iron With Stand.
The Leather & Vinyl Weld/Replicator is applied to the rear of the damage with the Teflon Sheet (and Leather & Vinyl Weld Backing Fabric for larger areas), and the area is then heat-cured using a Termal Sealing Iron With Stand. Wetting the Teflon Sheet can make it more pliable for easier application, and our GT24 Silcone and Resin Remover is great for removing excess resin from the Leather & Vinyl Weld/Replicator.
For smaller damage such as claw marks and minor cuts, you can use Aquafil Leather & Vinyl Filler and a Pallet Knife to bring your leather or vinyl back to its former glory.

ACHIEVING DAMAGE REPAIRS

The majority of leathers on the market are top coloured – meaning the leather has a dye sprayed on the surface to achieve the desired colour. Repairs to these leathers are generally pretty straightforward and easy to conceal with SCUFFmaster Dyes and leather repair products such as those found in the Liquid Leather Leather Repair Kit.

GLUEING AND FILLING

The most effective and widely used leather repair glues are what’s known as “contact adhesives” (Structural Contact Adhesive and Dutch Glue). These glues are used by applying a small amount to each side of the damage and allowed to dry before being joined together. To conceal the repair after Structural Contact Adhesive or Dutch Glue has been used, we offer Aquafil Leather & Vinyl Filler and Dutch Liquid Filler to fill any holes or recessions, and then the leather grain can be replicated as described in our Creating Leather Grain Impressions below.

Glues

Liquid Leather Structural Contact Adhesive is recommended for general repairs, whereas Liquid Leather Dutch Glue can be used for repairs needing additional strength. Dutch Glue also offers the advantage of not shrinking when dry.

Fillers

Aqualfil Leather & Vinyl Filler is recommended for use on areas that don’t flex and pull, whereas Dutch Liquid Filler is a more flexible alternative for those areas.

CREATING LEATHER GRAIN IMPRESSIONS

Once the job of repairing a cut, hole or tear in leather is complete, you will then need to hide the repair. You wouldn’t want surgical scars on your skin, so surely you won’t want them on your leather either! Thankfully, hiding scars is much easier on leather than it is on our skin, thanks to Liquid Leather’s Graining Mat with Additive.

Liquid Leather Graining Mat with Additive uses a twin tube system to mix the latex and hardener in the “curly whirly” nozzle when used with our Dual Cartridge Dispensing Gun.

Simply apply the Graining Mat on the area next to the repair and dry with a hairdryer. Once dry, you can peel off the latex and use this as your mould. Use Aqualfil Leather & Vinyl Filler or Dutch Liquid Filler to fill the leather repair area, then simply impress the latex mould onto the filler before it dries to recreate the graining texture.

Be sure to apply the latex mould to the filler in the correct grain direction to properly conceal the repair.

SCUFFmaster Dyes can then be used to re-colour the area of the repair, completely concealing your leather or vinyl repair.
