Adhesive options for neoprene suit patches

Context

The need was to attach patches to a neoprene suit and determine whether Gorilla Contact Adhesive was suitable.

The patch material, dimensions, location, surface finish, and whether the work was reinforcement or tear repair were not specified.

Advice received

Gorilla Contact Adhesive was described as workable on neoprene, particularly for fabric or reinforcement patches in areas that do not stretch heavily. The response cautioned that it could peel over time in high-movement areas.

Purpose-made flexible repair products were preferred:

• Black Witch neoprene adhesive
• Stormsure
• Gear Aid Aquaseal

The suggested bonding process was:

1. Clean the surfaces with isopropyl alcohol.
2. Lightly rough both bonding surfaces.
3. Apply a thin layer to both surfaces.
4. Wait five to ten minutes until tacky.
5. Press the patch firmly into place.
6. Leave it for 24 hours.

For seams, structural repairs, and high-stress locations, the response recommended a neoprene-specific adhesive rather than Gorilla Contact Adhesive.

Editorial notes

The response grouped Black Witch, Stormsure, and Aquaseal together as "neoprene cement," although they are not necessarily the same type of adhesive or applied identically. The statement that they slightly dissolve neoprene and are what wetsuit manufacturers use was also too broad.

Preparation should depend on the actual suit and patch surfaces. Sanding could damage a smooth-skin finish, and solvent compatibility was not established for this suit. The relevant product instructions would need to determine preparation, application, and curing rather than treating the generic method as settled.

No adhesive was selected or tested, and no repair outcome was recorded.
