MARSHALLTOWN PermaFlex Finishing Trowels are crafted from the highest-grade stainless steel and designed for easier application of finish coat plaster, drywall compound, and EIFS. The stiff, thru-riveted backing plate and aluminium alloy Xtralite mounting work together to give your trowel superior hold strength and blade flatness. The blade’s rounded corners also reduce drag lines in your finishing work.
