Particle board as underlayment is typically used for which application?

• A. exterior sheathing
• B. steel framing
• C. laminated countertops
• D. concrete floor

Answer: (C)

Particle board provides a flat, uniform substrate that laminated countertops rely on. It bonds well with laminate adhesives and offers a stable surface that can be easily edged, making it a practical and economical choice for the core of laminated countertops. Its moisture sensitivity and lack of durability in exterior or structural applications explain why it isn’t used for exterior sheathing, steel framing, or concrete floors, where moisture resistance or different structural needs are required. So, the typical use is as the substrate for laminated countertops.
