Triple Hardened Plastering Trowel
Triple hardened stainless steel blade · Ergonomic handle · Available in 12", 16", and 18" — for plastering, rendering, and decorative coating applications.
Triple hardening means the blade goes through three separate hardening processes — each one increasing the steel's resistance to bending, wear, and deformation. The result is a blade that stays flat and true under heavy plastering pressure far longer than a standard or double-hardened trowel.

Key Features
Triple hardened blade
Three-stage hardening process creates exceptional resistance to bending and wear — the blade stays flat and true under heavy plastering pressure.
Superior longevity
Outlasts standard and double-hardened trowels significantly — a better long-term investment for professional plasterers who work daily.
Ergonomic handle
Comfortable grip designed to reduce hand fatigue during extended plastering sessions on large wall and ceiling areas.
Stainless steel blade
Rust-resistant stainless steel — easy to clean after use and built to handle lime plaster, gypsum, cement render, and decorative coatings.
Applications
Large wall & ceiling areas
Choose 12" for patching, corners, and detail work. The 16" is the most versatile size for standard room plastering. Use the 18" for large open walls and ceilings where covering ground quickly matters. Clean the blade immediately after each coat before material hardens.
