 Smooth finishes can be obtained by placing a sheet of polyethylene or waxed paper over soft
deposits. Remove when hardened. Trowels or spreading tools can be moistened with water
between strokes for smoother deposits when applying.
Use M-50 Nobond Wax on surfaces not to be bonded. For detailed reproductions from molds and
patterns apply Nobond in several coats. Allow each coat to dry then buff before applying
additional coats. Brush a thin coat of compound on mold surfaces before casting the remainder of
the mix.
Use reinforcing screens and tapes to minimize warpage and to increase overall strength. When
casting large, deep shapes, pour compounds in several steps, allowing prior deposits to semi-
harden and cool before adding additional compound.
