MARSHALLTOWN EIFS Trowels are essential for EIFS applications. The square or U-shaped notches easily spread large quantities of mortar or adhesive and leaves behind even grooves for smooth EIFS paneling. The lightweight aluminum alloy mounting is riveted to a Carbon Steel blade. Along with blade material and notch shape, you can also choose your preferred notch size and handle material. Choose between a resilient DuraSoft® handle for increased comfort or a curved hardwood handle that molds to your hand.
