Finish curved concrete surfaces, swimming pools, and radius walls with complete confidence. The Marshalltown SP16SD Flexible Pool Trowel is crafted specifically to flex to almost any radius without gouging or marking the surface.
Unlike standard rigid flatwork trowels that bind or dig when working on contoured forms, the SP16SD features a highly flexible blade made from premium hardened and tempered spring steel. It is fitted with a shortened Xtralite® aluminum mounting that allows the entire length of the 16" x 4-1/2" blade to conform naturally to concave or convex shapes. Combined with fully rounded ends that eliminate line marks, this trowel enables finishers to achieve a glass-smooth, seamless burnish on pools, spas, radius curbs, and decorative concrete features.
Flexible High Carbon Steel Blade: Crafted from highest-grade hardened and tempered spring steel that flexes smoothly under pressure to match radius contours.
Shortened Xtralite® Mounting: The high-strength aluminum alloy mounting is purposefully shortened to give the blade maximum flexibility along its full length while maintaining a rigid handle connection.
Gouge-Free Rounded Ends: Both corners are precision-rounded to prevent digging into wet concrete, ensuring line-free passes on curved walls and bottoms.
Ergonomic DuraSoft® Cushion Grip: Fitted with Marshalltown's signature resilient DuraSoft handle to absorb impact shock, reduce fatigue, and provide a non-slip hold in wet pool-finishing environments.
Swimming Pools & Spas: The industry-standard hand tool for troweling curved plaster, gunite, shotcrete, and pool finishes.
Radius Curbs & Curved Walls: Excellent for smoothing radius formwork, round planters, retaining walls, and decorative architectural concrete.
Tank & Silo Linings: Ideal for applying protective mortars and linings to round agricultural or industrial tanks.
