9-1/2" x 4" Gum Rubber Grout Float is a professional-grade tool designed for applying grout to tile joints. It features a non-stick gum rubber surface that ensures smooth application and prevents the grout from sticking to the float. The 2 rounded corners help prevent gouging of grout joints, while the 2 square corners ensure complete grout coverage in corners. The extra thick aluminum backing plate provides maximum leverage for applying grout into joints, and the premium gum rubber is laminated to a lightweight, closed cell core that is built to last. The Grout Float is a durable and easy-to-use tool that is essential for any tiling project.
