Complete Waterproof Bathroom Wall Protection Using Professional KERDI Technology

The Schluter KERDI-BOARD-KIT is a complete solution for creating waterproof and tile-ready wall surfaces around bathtubs and acrylic shower bases. Designed for both contractors and homeowners, this kit simplifies bathroom waterproofing by providing everything needed to construct durable, moisture-resistant wall assemblies.

The system is engineered to eliminate the need for traditional gypsum or cement backer boards. Instead, lightweight KERDI-BOARD panels are mounted directly onto stud framing to create a strong, flat, and waterproof substrate ready for tile installation.

Key advantages include:

• Mold and moisture resistance

• Reduced construction time

• Lightweight handling for easier installation

This makes it ideal for new construction and renovation projects alike.

Vapor Tight Construction to Prevent Moisture Damage and Mold Growth

One of the strongest advantages of KERDI-BOARD technology is its ability to create vapor-tight waterproof assemblies. Bathrooms are high-moisture environments, and improper waterproofing can lead to structural damage over time.

This kit helps protect walls from moisture penetration by:

• Blocking water vapor migration into wall cavities

• Protecting wood framing from rot and degradation

• Supporting long-term tile adhesion performance

Waterproofing is typically carried to at least the height of the showerhead, ensuring effective splash and spray protection. For higher wall installations or ceiling coverage, additional KERDI-BOARD-KIT materials can be added.

Lightweight Panel Construction for Faster and Safer Installation

KERDI-BOARD-KIT panels are significantly lighter than traditional cement backer boards, making them easier to transport, cut, and install.

Installation benefits include:

• Cement-free, dust-free cutting

• Reduced fatigue during vertical wall installation

• Easier handling in renovation projects with limited workspace

The panels can be cut using simple hand tools, making it easier for both professionals and DIY installers to achieve precise fits around plumbing fixtures and wall corners.

Engineered Coverage Capacity for Standard Bathroom Dimensions

The KERDI-BOARD-KIT provides sufficient material to cover up to 101 ft² (9.4 m²) of wall surface. In typical bathroom layouts with 8-foot ceilings, this translates to approximately 12 linear feet (3.6 m) of wall coverage.

Ideal applications include:

• Bathtub surrounds

• Shower enclosures

• Acrylic base shower wall systems

• Residential and light commercial bathrooms

However, larger spaces may require additional KERDI-BOARD or KERDI-BAND waterproof sealing tape to complete full enclosure waterproofing.

Professional-Grade Tile Substrate for Long-Term Structural Performance

KERDI-BOARD-KIT does more than waterproof; it also provides structural support for tile installations. The rigid, dimensionally stable panel surface helps ensure tiles remain firmly bonded to the substrate.

Important installation considerations:

• Heavy fixtures such as grab bars must be anchored into wall studs or solid blocking behind the panels

• Follow Schluter installation guidelines for load-bearing accessories

• Maintain proper fastening spacing for maximum panel stability

When installed correctly, KERDI-BOARD creates a durable base for ceramic, porcelain, or natural stone tile finishes.

Contractor-Ready System Designed for Efficient Bathroom Remodeling

The KERDI-BOARD-KIT is designed to simplify bathroom waterproofing projects while maintaining professional construction standards. By combining waterproofing, substrate preparation, and tile readiness in one system, installation time can be significantly reduced.

This kit is especially useful for:

• Bathroom remodeling contractors

• Homeowners upgrading existing bathtub surrounds

• New residential construction projects

The result is a cleaner, faster, and more reliable tile installation process.
