Section 1: MECHANICAL INSTALLATION
2) Mask hull area around foundation saddles for easy clean ‐ up and to create outline (highlighted in
blue) of surface area to receive adhesive as shown in red, Fig 7.
3) Raise jig clear of foundation.
4) Thoroughly clean with alcohol or acetone all areas (highlighted in red, Fig 7) of girders to be
bonded to remove any contaminates. Use new paper towels for cleaning, not shop rags.
5) Remove all paint and gel ‐ coat from bond surfaces so that adhesive will bond directly to laminate
fibers and resin as shown in Figure 7.
6) Thoroughly sand girder bond
surfaces with 80 grit
sandpaper. (IMPORTANT –
BOND STRENGTH MAY BE
REDUCED IF THIS STEP IS
SKIPPED.)
7) Wipe surfaces clean from dust
with alcohol or acetone using
new paper towels, not shop
rags.
8) Re ‐ position installation jig on
girders and double ‐ check that
the adhesive gap is within the
adhesive manufacturer’s
maximum recommended
thickness. (Note gap will be
larger due to absence of gel ‐
coat.)
1.4.2 Aluminum/Steel Hull Preparation
1) Follow steps 1 ‐ 4 of fiberglass hull preparation.
2) Remove all oxidation via sanding with 80 grit sandpaper/grinding. (IMPORTANT – BOND
STRENGTH MAY BE REDUCED IF THIS STEP IS SKIPPED.)
3) Wipe surfaces clean from dust with alcohol or acetone using new paper towels, not shop rags.
4) If using Plexus MA590 adhesive, apply Plexus PC ‐ 120 surface conditioner to the bonding
surfaces. These instructions are located at the end of this section.
5) The gyro should be installed when PC ‐ 120 is confirmed dry.
Note when installing gyro on aluminum/steel hull, the sanding and PC ‐ 120 (if
using Plexus MA590 adhesive) application for both hull and gyro saddles
should be done as close to the same time as possible. This will minimize
oxidation on bond surfaces and help improve adhesive bond strength.
Clean all areas of
girders to be
bonded – no
paint, no gel ‐ coat
Tape girders
around fixture to
make clean ‐ up
easier
