Buying Guide
Backer board choice depends on moisture exposure, substrate, and tile type. Consider these factors:
- Moisture resistance: In showers or tub surrounds, waterproof or moisture-resistant boards reduce mold risk.
- Board type: Foam-core GoBoard provides smooth, lightweight support; cementitious or gypsum boards offer rigidity and tile adhesion strength.
- Fastening system: Choose washers or fixers compatible with your substrate (wood framing, concrete, or metal studs).
- Cutting and finishing: Diamond hole saws and jigs improve precision for outlets and fixtures.
- Ease of installation: Lifting tools and simple fasteners reduce installation time and labor.
FAQ
- What backer board is best for showers?
Waterproof or moisture-resistant boards, such as foam-core GoBoard, are generally recommended for showers and tub surrounds due to enhanced moisture resistance.
- Do I need special washers for gypsum board?
Yes. Four-claw or similar fixing washers designed for gypsum, insulation, or backer boards improve grip and reduce delamination when used with appropriate screws.
- Can I use standard screws with foam backer boards?
Yes, but ensure screws match the board’s thickness and substrate to avoid tearing or protrusion. Follow product guidelines for best results.
- Are diamond hole saws necessary for gypsum or tile work?
Diamond hole saws provide cleaner cuts and longer life on ceramic, gypsum board, and tile joints, especially in edges and awkward openings.
- What installation accessories improve tile adhesion?
Proper washers and fixing discs, along with compatible adhesives, help secure backer boards and maintain surface integrity under tile loads.
