Buying Guide: Key Purchase Considerations
- Waterproofing vs. insulation: Determine whether you need a dedicated waterproof board, a combined board with built-in waterproofing, or a membrane system for joints and seams.
- Install environment: For high-moisture areas like steam showers, prioritize materials with robust moisture resistance and minimal dimensional changes when wet.
- Board thickness and density: Thicker boards provide rigidity and reduce risk of flexing; ensure compatibility with tile thickness and substrate requirements.
- Compatibility with substrates: Check whether fasteners and bonding methods are suitable for wood studs, metal studs, or concrete structures.
- Installation workflow: Some bundles simplify installation by combining multiple components (board plus Kerdi/Schluter components) in a single package.
- Tile bonding considerations: Choose products with bonding-friendly surfaces (fleece, resin coatings, or compatible adhesives) to ensure long-lasting tile adhesion.
- Size and packaging: For larger showers, consider bulk bundles to minimize seam gaps and reduce on-site material handling time.
- Maintenance and life cycle: Look for materials with proven performance records in preventing moisture-related issues such as mold, swelling, and delamination.
