Procedure:
1. Use jigs or clamps to hold basin sections together temporarily.
When aligned, re-drill any holes that do not align properly.
2. Prepare the joint. Use Acetone and a scraper to clean the faces of
the joint to remove smears or deposits of fiberglass release agent,
loose paints or filler materials such as Plasticine. Abrade the
mating faces of the basin to at least 50mm from the corner.
Clean and abrade the corners. Clean and abrade 12mm of the
exposed edges of the basin adjacent to the joint (see Fig 6).
Note that the key area for sealing and gluing is regarded as the
50mm part of the joint closest to the water.
3. Wipe with acetone to remove dust.
4. Apply 5mm diameter beads of sealant around the perimeter of the
abraded prepared areas. Fill in the area with a 5mm bead in striped
or a serpentine pattern. Sealer is to be applied to both faces in this
manner.
5. Pull the basin sections close together so that beads of sealant
touch. Fit a bolt in each hole, with a nut & 2 washers, and do up
finger tight.
6. Smooth over the joint with spatula, removing excess sealant or
adding extra to fill hollows.
7. Do not disturb for 2 hours.
8. After 2 hours, bolts can be tightened further to put pressure on joint.
