The area was prepared using a disk grinder to roughen the surface and to make a cross-hatching pattern on the surface. A coat of Belzona 9411 was applied to the inside of the formers, and the edges where material will be pushed out. Belzona 1111 was applied to the shaft and covered the entire area using a brush and the mixing spatula to apply the product. Also, the inside of the formers were covered and evenly spread.
