COLOURLOCK Rep Glue — special adhesive for precise leather repairs

What is COLOURLOCK Rep Glue for? — This special adhesive bonds leather and faux leather permanently, flexibly and right on the spot, and it's ideal for tears, lifted edges and repairs with a textile or leather backing.

COLOURLOCK Rep Glue is a highly effective, flexible-curing special adhesive for leather and faux-leather repairs. It's perfect for tears, split areas, lifted edges, backing patches and fixing small pieces of leather in place. The glue bonds the materials hard yet stays elastic, so it backs up repairs on parts that keep moving — bolsters, steering wheels, armrests, furniture edges, bags or shoes.

• Strong, flexible hold – Ideal for tears, edges and backing patches.
• Precise to work with – Controlled application for spot-on repairs.
• Broad material compatibility – Works on leather, faux leather and textile backers.

Bonding technology & how it works

Rep Glue is built on an elastic, high-grab adhesive formula that stabilises the repair without making the material go stiff. The glue soaks well into the leather fibres and, once dry, forms a flexible bond that moves with the panel and stays load-bearing for the long haul. That keeps the spot from cracking open again, so repairs hold up to everyday use. It really shows its strength on structural damage or on repairs you plan to recolour later, where you want a solid base to build on.

How to use it & best practices

Clean the area you're repairing and let it dry fully. Then lay down Rep Glue thin and precise. On tears, back the spot with textile or leather before you smooth the surface with filler or binder. Let the glue dry all the way before any colour or top coat goes on. Wipe off any excess while it's still wet — it comes off easily. Because it stays flexible after curing, you can carry on working it professionally without hard transitions.

Results & where to use it

Once it's dry you get a solid, lasting and still-elastic bond. Rep Glue is ideal for automotive leather, furniture, bags, shoes, accessories and interior parts. It's not a large-area laminating glue — it's made for precise repair points where you need firm hold and flexibility in equal measure. Perfect for prepping repairs that you'll then fill, colour and seal with a top coat.
