This 15-inch hard plastic trowel disc is a heavy-duty replacement pad designed for handheld concrete trowels and wall plaster smoothing machines. Built with a 0.32-inch thick ABS plastic construction, it offers excellent rigidity, impact resistance, and wear resistance, holding up to the demands of long, high-vibration construction work. Featuring a full loop-side (soft) hook-and-loop backing, this disc is engineered to securely attach to the standard hook-side (rough) velcro base that comes pre-installed on most trowel machines. The strong bond prevents slipping or detachment during use, while the peel-and-stick design allows for quick, tool-free replacement, minimizing downtime on the job site. The textured grid surface is purpose-built for rough plastering, mortar leveling, cement slurry lifting, and concrete surface preparation. It excels at knocking down uneven spots, spreading mortar evenly, and creating a smooth, consistent base layer for your final finishing work. Suitable for both professional contractors and DIY enthusiasts, this trowel disc is a reliable, cost-effective consumable for interior wall plastering, ceiling smoothing, small concrete floor repairs, and various other construction and renovation projects. Note: Trowel machine is not included, for illustration only.
