Description
The Z Counterform Full Bullnose Countertop Form is a patented, single-use extruded PVC plastic forming system engineered specifically for cast-in-place concrete countertops, producing a fully rounded bullnose edge profile (180-degree radius on the exposed top and bottom edges) for a smooth, classic, and user-friendly appearance with excellent release properties and reduced finishing needs.
Key Technical Specifications:
- Material: High-quality extruded PVC (polyvinyl chloride), durable and stable for single-use during concrete placement and curing.
- Edge Profile: Full bullnose design — features a complete rounded radius on both the top and bottom of the exposed vertical edge, creating a symmetrical, fully curved profile without flat vertical faces on the overhang side.
- Formed Edge Height/Thickness: Creates a consistent 2-1/4″ (2.25 inches / 57 mm) vertical edge thickness for the countertop slab.
- Installation Substrate Compatibility: Designed for direct attachment to 1/2″ (12.7 mm) cement backer board (e.g., Durock or HardieBacker) secured to cabinetry or support structure.
- Attachment Method: Secured using 5/8″ x #10 panhead screws into the cement board substrate; no additional adhesives required.
- Backwall/Return Components: Includes dedicated backwall pieces for forming the rear (wall-side) edge, ensuring uniform slab thickness and clean transitions (note: backwall quantity may vary slightly by package to accommodate typical installations).
- Packaging Options:
- Full package: Typically 60–64 linear feet of profile edge forms (e.g., eight 90″ or 7.5–8′ sections) + corresponding backwall pieces (e.g., six to eight 90″ sections, often providing 45–60 linear feet).
- Half package: Approximately 30–32 linear feet of profile edge forms + backwall pieces (e.g., four sections each).
- Forming Mechanism: Patented Z-shaped profile enables self-aligning hook engagement with the substrate edge for secure support during the pour; after concrete achieves full cure strength, forms are snapped off at engineered break points for clean, damage-free release, revealing a smooth, rounded concrete edge.
- Application: Optimized for horizontal cast-in-place pours over cabinetry; suitable for both DIY and professional residential or commercial installations desiring a traditional, fully rounded edge that enhances safety (no sharp corners) and pairs well with classic or transitional design aesthetics.
- Performance Features: Supports quick setup and removal; delivers high-quality, void-minimized edges with minimal post-pour grinding or polishing; compatible with standard concrete countertop mixes (e.g., high-strength GFRC or cast-in-place formulations); the full radius profile provides enhanced durability at edges and good performance for moderate curves or complex layouts.
This system simplifies the production of full-bullnose concrete countertops, eliminating traditional woodworking or reusable forms while ensuring consistent, repeatable professional results. Ideal for achieving elegant slab overhangs, seamless inside/outside corners, and precise cutouts when combined with complementary Z Counterform accessories.
