Molded Rubber FloatThe 8 In. x 4 In. molded black sponge rubber float pad is securely cemented to the flat aluminum back. The aluminum backing is lightweight, yet strong for use on any sand surface. The material is uniquely formulated to smooth out irregularities on the surface of plaster and concrete applications. The firm rubber opens up plaster and stucco to allow it to breathe and resist cracking. The dense pad is 5/8 In. thick that creates a cushioning for considerable wear before replacement. The precisely balanced 7-1/4 In. smooth wood handle provides a comfortable grip. Proudly made in the USA.
