10. Sand the cast base to the desired final finish. Begin with 50-grit sandpaper or a file if the
base is extremely irregular. Finish with 80-grit sandpaper.
11. Bond the hardware to the cast base using the hardware bonding procedure in section
6.2 (Figure 6-3c). Drill oversized and standard pilot holes for the fasteners through the
cast base. Allow to cure thoroughly before applying loads to the hardware. Apply three
coats of resin/hardener mixture to the base before final finishing.

Figure 6-3 Hardware casting is an excellent method for installing a piece of hardware that is not flush to the deck such as a winch.
Bond threaded rods or studs into the substrate (instead of bolts or screws) and attach
the hardware with nuts. This variation is appropriate for many engine, motor or
machine installations. Coat the base with wax/mold release to make the hardware
removable. Although the hardware is not “bonded” to the substrate, the epoxy still
provides a bearing surface that perfectly matches and supports the base of the
hardware.
Figure 6-4 Bond threaded rods or studs
into the substrate as an alternative for easily
removable hardware.
1. Place a nut on the stud to fit just above the surface when the stud is dry fitted in the
hole. Prepare the studs/threaded rods by waxing the upper ends (above the surface)
and cleaning the lower ends (below the surface).
2. Wet out the hole with epoxy and allow it to penetrate. Fill the hole with an epoxy/404
or 406 mixture, allowing for the volume of the stud and nut. This may be a good application
for Six10 Epoxy Adhesive if multiple and/or deep holes are to be filled.
