One-component adhesive and two-component adhesives are used.
One-component adhesive combines resin and hardener in one package.
One-component adhesive cures through a chemical reaction triggered by heat or moisture.
Two-component adhesive requires mixing and applying pressure to cure.

Repairing Plastic Cracks with Two-Component Adhesive

Steps include: choosing adhesive, cleaning, grinding a "V", mixing adhesive, applying filler, sanding and contouring, and painting.
