Approved two-part adhesives come in multiple mixing ratios – 1:1, 2:1, or 10:1. Use the correct dispense gun and mixing nozzles for the adhesive type. Failure to do so will result in poor adhesion and will void the systems warranty.

WARNING: Check the approved two-part adhesive being used to verify it is compatible with the hull material (epoxy resin fiberglass, polyester resin fiberglass, gel coat, etc). Some adhesives require a primer when used with certain materials. Plexus primer must be used if performing an aluminum installation with Plexus MMA.
