Overview: These options cover cutting, sealing, and joint work for cement board tile projects. The PacTool shears simplify custom cuts around outlets and corners. The USG liquid membrane delivers fast-drying waterproofing. The Goldblatt and QEP products address tape and joint integrity, helping you achieve a smoother tile surface with fewer callbacks.
PacTool SS724 Snapper Shear Pro
The PacTool SS724 Snapper Shear Pro is a cutting tool designed for hardiebacker fiber cement board. It accepts a cordless drill (18V or higher) and enables 360° rotation for complex cuts. It’s suitable for straight cuts, curves, and circles down to 3 inches, offering ergonomic advantages over traditional hand shears.
Key features include drill compatibility, capable cutting depth for 1/4″ to 1/2″ HardieBacker boards, and versatile shaping for tile installations around corners, outlets, and plumbing fixtures. The design supports efficient, precise cuts, reducing material waste and labor time on tiling projects.
PacTool SS424 Backerboard Shear
The PacTool SS424 Backerboard Shear is a contractor-grade tool designed for precise fiber cement underlayment cuts. Equipped with a 6.5-amp motor, it powers through up to 1/2-inch thick Hardiebacker board. This tool focuses on trimming and shaping the board rather than broad cutting, enabling clean inside corner cuts with minimal breakage.
Its reversible, replaceable blades and high-speed operation support long runs of straight and angled cuts. The tool is optimized for efficient tile installation workflows, especially when fitting backerboard around outlets, corners, and fixtures in moisture-prone areas.
USG DUROCK Brand Liquid Waterproofing Membrane
This liquid waterproofing membrane from USG DUROCK is designed for seamless moisture barriers in tile installations. It can be rolled, brushed, troweled, or sprayed, offering a fast-drying solution for quick turnarounds. The membrane presents a low permeance rating, suitable for showers, backsplashes, and areas with high moisture exposure.
Designed to form a flexible, protective layer, it helps prevent water intrusion behind tile and reduces the likelihood of mold and staining. It complements cement board systems by providing an additional line of defense in wet environments.
Goldblatt Cement Board Tape & Screws Set
The Goldblatt set combines 50 feet of cement board tape with 150 screws and a drill bit. The fiberglass mesh tape is alkali-resistant and self-adhesive, reducing taping time and improving joint strength. The included screws feature a star drive with a T-25 bit for easy installation, designed to prevent cam-outs and facilitate rapid fastening in cement board joints.
Application includes reinforcing joints between cement boards in moisture-prone spaces and ensuring a flush, durable tile substrate. The ruspert coating on screws provides rust resistance, extending the life of installations in showers and wet kitchens.
QEP Cement Board Joint Tape
The QEP 99605 Cement Board Joint Tape provides a 2-inch wide, 150-foot long fiberglass mesh with self-adhesive properties. This tape is designed to create smooth joints between cement board panels, promoting better adhesion for thinset and tile. It reduces joint telegraphing and helps produce uniform tile surfaces across larger areas.
Ideal for large shower enclosures, backsplashes, and flooring projects, the tape’s self-adhesive feature speeds up installation and minimizes delays caused by loose joints. It works in conjunction with standard cement board screws and waterproofing membranes for a cohesive system.
Buying Guide: How to Choose Cement Board Accessories
- Project type and moisture exposure: For high-humidity areas, pair cement board with a waterproofing membrane and a high-quality joint tape to reduce water intrusion and crack risks.
- Cutting needs: If you expect many curved or complex cuts, a 360°-capable shear (like PacTool options) can save time and improve accuracy over manual scoring and snapping.
- Board thickness: Verify the maximum board thickness supported by cutting tools. Most fiber cement backer boards are 1/4″ to 1/2″ thick; choose tools rated for those ranges.
- Attachment hardware: Use corrosion-resistant screws with appropriate drive types and coatings for wet environments to extend substrate life.
- Installation efficiency: Self-adhesive, alkali-resistant joint tape reduces setup time. Combine with membranes for faster, more reliable moisture management.
- Compatibility: Ensure all selected products work with your tile setting materials, including mortars, thinsets, and primers, to maintain warranty and performance.
- Safety: Wear eye protection and gloves when cutting or drilling cement board. Ensure proper dust control with vacuums or wet-cutting methods as needed.
Overall, selecting compatible tools and materials tailored to cement board tiling projects minimizes waste and improves long-term performance. The combination of cutting tools, joint tapes, fasteners, and waterproofing membranes creates a robust substrate ready for tile installation.
