How is trapped air removed from under plastic laminate?

• A. Hammering
• B. Sanding
• C. Rolling out with a roller
• D. Steam pressing

Answer: (C)

When applying plastic laminate, trapped air between the laminate and the substrate causes bubbles and weak adhesion. Using a laminating roller provides steady, uniform pressure that pushes those air bubbles out toward the edges and helps the adhesive wet the surface evenly. This seating action creates a smooth, fully bonded layer with no air pockets. Hammering would dent the surface, sanding would mar it, and steam pressing could cause moisture-related issues like warping or delamination. So rolling with a roller is the effective way to remove trapped air and ensure a solid bond.
