Description
Porcelain slab fabrication presents unique challenges that set it apart from natural stone work, and this eased/straight edge template for 2cm+2cm laminated porcelain addresses those demands directly. The 1-9/16 inch laminated build-up creates a countertop thickness that rivals solid 3cm stone while keeping the installation weight manageable. Porcelain's brittle, vitrified body requires careful attention to chip prevention at every stage of edge profiling. This template calls for a 25mm roughing finger bit at 3500 RPM with a full polishing progression from 50 grit metal bond through 3000 grit resin before the final buff at 4000 RPM. The result is a sharp, factory-quality eased edge that maintains porcelain's characteristically uniform appearance across the entire exposed surface.

Installation Overview
Laminating two 2cm porcelain slabs demands a different adhesive strategy than natural stone. Use a flexible, porcelain-rated methacrylate or polyurethane adhesive that accommodates the near-zero porosity of sintered surfaces. Standard stone epoxies may not bond reliably to porcelain's dense body. Clean both bonding faces with isopropyl alcohol and abrade lightly with 80-grit sandpaper to create mechanical tooth before applying adhesive. Clamp evenly and allow the manufacturer's recommended cure time, typically six to eight hours. Once laminated, the eased edge profile is cut with a 25mm finger bit at 3500 RPM. Keep feed rates conservative at 40-60 IPM to minimize edge chipping, which is porcelain's primary failure mode during fabrication. The polishing sequence begins at 50 grit metal bond at 2800 RPM and progresses through nine positions to the final buff at 4000 RPM. Each pad should overlap the previous pass by at least 50 percent to ensure uniform scratch removal. Pay particular attention to the lamination seam at 2500 RPM, as porcelain's opacity makes seam visibility less forgiving than with translucent natural stones. Apply a penetrating sealer to the finished edge only if the porcelain manufacturer recommends it, as many fully vitrified products do not require sealing.
CNC Cutting Notes
Porcelain demands diamond-only tooling throughout the entire cutting and polishing process. Set the roughing pass at 3500 RPM with a feed rate of 40-60 IPM using the 25mm finger bit. Take shallow passes of 0.040 inches maximum to prevent the brittle porcelain body from spalling. Maintain high coolant pressure directed at the cutting interface to flush debris and control temperature. During polishing, start at 50 grit metal bond at 2800 RPM and increase spindle speed incrementally to 4000 RPM by the buff stage. Avoid sudden direction changes in your toolpath, as porcelain is prone to micro-chipping at points where the tool reverses. A continuous climb milling path around corners produces the cleanest results on eased profiles.
Material Compatibility
Porcelain countertop slabs from brands such as Laminam, Sapienstone, and Florim are well-suited to this eased/straight laminated profile. These sintered surfaces are extremely hard, typically rating 7 or above on the Mohs scale, which means they resist scratching but are prone to brittle fracture under impact. Thinner porcelain panels below 12mm should not be laminated using this template without additional reinforcement backing. Large-format porcelain slabs with through-body veining produce the most convincing laminated edges because the pattern continues through the seam. Solid-color porcelain slabs are the easiest to laminate invisibly since there is no vein pattern to match at the joint.
Where to Buy
Porcelain countertop slabs are stocked by specialty distributors such as Cosentino (Dekton line aside, they carry porcelain options), SapienStone dealers, and Florim. Contact your regional large-format porcelain distributor for slab availability and pricing.
