Best Glue for Leather-to-Leather Bonding

What is the best glue for bonding leather to leather?

It depends on the size of the job. Selleys names two products:

• Selleys Power Grip for small jobs.
• Selleys Kwik Grip Horizontal for larger ones.

Leather is named on the technical data sheets of both, so neither is a stretch application. The difference is how they work, and that determines which suits your repair.

Small jobs: Power Grip

Power Grip is a high strength household glue that is extremely flexible and shock/impact resistant. Flexibility is what leather needs — a rigid glue line in a strap or a seam cracks the first time the leather bends.

Property	Typical result
Colour	Transparent with a yellow tinge
Setting time	3 minutes
Initial bond time	12 hours
Service temperature	−15 °C to +120 °C
Pack sizes	4 g, 5 g, 8 g, 10 g and 20 g tubes

The 12-hour initial bond figure comes with an important qualification in the TDS: that is the time for porous surfaces such as wood and ceramics, and you should allow longer for non-porous surfaces. Finished leather with a sealed or coated face behaves more like a non-porous surface than a porous one, so give the joint more than half a day before loading it. There is also a useful tip on the sheet: to reduce set time on non-porous surfaces, keep the surfaces apart for 30 seconds before bringing them together.

Power Grip is also dishwasher safe and paintable, and is described as water and weatherproof — though it is not for permanent water immersion, and it will yellow on direct exposure to UV, which matters on a pale leather that lives in sunlight.

Larger jobs: Kwik Grip Horizontal

For anything bigger than a small repair — recovering a panel, bonding a full leather face to a backing — a contact adhesive is the better tool. You coat both surfaces, let the solvent flash off, then bring them together and the bond forms across the entire area at once. No clamping, no waiting for a wet adhesive to dry through material it cannot breathe through.

Property	Kwik Grip Horizontal	Kwik Grip Vertical Gel
Open time	20–40 minutes	20–40 minutes
Full cure	—	24 hours
Heat resistance	130 °C	130 °C
Application temperature	—	10 °C – 35 °C
Coverage	—	0.25 m² per 40 g of one surface

Kwik Grip Horizontal is intended for cork, rubber, felt, canvas, leather, metals, timber, laminated plastics, hardboard and compressed board. Its one significant limitation for leather work: it is not suitable for rough or ill-fitting surfaces. Leather that has stretched, curled or no longer lies flat against its backing needs Kwik Grip Vertical Gel instead, which lists leather among its uses and is formulated with more body.

How to bond leather

1. Test on a hidden area first. Solvent adhesives can discolour or harden leather — Selleys' own guidance for its plastics adhesive warns that if using it on leather, you should test on an inconspicuous area first, because the adhesive may discolour or cause leather to harden. Treat that as the standard precaution for any solvent product on leather.
2. Clean both faces and let them dry. Leather carries dressings, waxes and conditioners, and an adhesive cannot bond through them.
3. Dry-fit and mark your alignment. Contact adhesive grabs immediately on contact and cannot be repositioned.
4. Power Grip: apply to one surface, bring the pieces together, and clamp or tape to support the joint until the adhesive sets. Wipe the nozzle clean and replace the cap immediately — the product cures rapidly.
5. Kwik Grip: apply to both surfaces and spread evenly, ensuring they are completely covered. Keep them apart until the adhesive is almost dry — approximately 20 minutes, no more than 40 — then position carefully and press together, working from one edge across. Secure with a roller or by hammering through a padded block from the centre outwards.
6. Allow the full cure time before putting the item into service: 24 hours for Kwik Grip Vertical Gel; longer than 12 hours for Power Grip on non-porous leather.

Limitations

• Test on leather before you commit. Some solvent adhesives discolour or harden it.
• Power Grip: not for polyethylene or polypropylene plastics; not for permanent water immersion; yellows under direct UV.
• Kwik Grip: not for polyethylene or polypropylene plastics; do not use below 10 °C; Horizontal is not suitable for rough or ill-fitting surfaces.
• Both are solvent-based in use — ventilate the area, and let contents dry completely before disposal.

Common questions about gluing leather

Will the bond stay flexible?

Power Grip is described as extremely flexible and shock/impact resistant, and bends on impact. Contact adhesives lay down a thin continuous film rather than a rigid bead, which also flexes well.

How long before I can use the item?

Power Grip's initial bond time is 12 hours on porous surfaces, with longer allowed for non-porous ones. Kwik Grip Vertical Gel reaches full cure in 24 hours.

Will the glue line show?

Power Grip is transparent with a yellow tinge and will yellow further under direct UV. Kwik Grip Vertical Gel is beige and opaque. On light-coloured leather, keep the adhesive back from visible edges.

How much Kwik Grip do I need?

Work on 0.25 m² per 40 g of one surface, and remember you are coating two — so roughly 80 g per square metre of finished bond, more where the leather is absorbent.

Can I use an epoxy?

Araldite Super Strong lists leather among its surfaces but its technical data sheet directs you to pre-test on leather and rubber to determine suitability. It is also rigid and its bond softens above 60 °C, so it is rarely the right choice for something that flexes.

What about leather shoes?

Different job, dedicated product — see how to repair shoes and Selleys Shoe Fix.

How do I clean up?

Power Grip: uncured product with turps or acetone, cured product can be sanded and scraped. Kwik Grip: mineral turps while wet — see how to remove Kwik Grip once dry for cured adhesive.
