Leather Glue WB
Leather Glue WB
Professional water-based polyurethane adhesive for leather repair. Delivers a strong, flexible bond without stiffening the substrate — ideal for fixing delamination, bonding patches/backing pieces and stabilising crack lines before filling and recolouring.
What It Does
Leather Glue WB wets the leather fibres and forms an elastic polyurethane bond that resists peeling and micro-cracking under flex. Use it to re-laminate lifted finish layers, fix lining/substrate separations, set reinforcement patches and close micro-splits prior to filling.
Designed for professional restoration workflows — integrates cleanly into the “glue → fill → colour → top coat” process.
Where It Works
- Automotive & aviation interiors (seat bolsters, armrests, panels)
- Furniture & upholstery (delamination, edge repairs)
- Leather goods & apparel (patching from the inside, seam stabilisation)
Suitable for finished/pigmented and corrected-grain leathers. Not intended for suede/nubuck.

Tips & Related Products
- Surface prep: clean and degrease the area before bonding to maximise adhesion.
- Thin coats: prefer a thin, uniform layer; avoid pools that slow drying.
- Pressure: maintain steady pressure (clips/tape/weight) until initial set.
- Workflow: after cure, level with Surface Repair / Light Filler / Heavy Filler, recolour with Leather Colourant, seal with Leather Top Coat.
Safety Notes
Work in a ventilated area. Avoid contact with eyes/skin. Keep container closed when not in use. Always test on a hidden area before full application.
