GENERAL PROCEDURES (Continued)
5. Immediately after grinding, apply the repair
patch. Cut a piece of glass mat that will extend
25 mm (1 in) beyond the damaged area.
Prepare a mixture of vinyl ester resin and soak
the glass mat in it. Lay the resin soaked glass
mat over the damaged area and smooth out the
patch using a spreader. The patch should lay on
the surface of the composite member as
illustrated.
6. Allow the patched area to cure for at least 1.5
to 2 hours at 24
°
C (75
°
F). Curing will take
longer at colder temperatures. A heat lamp
placed no less than 45 cm (18 in) from the
repair for approximately 15 minutes will help
decrease cure time. After the patch has cured,
grind the repair until it is flush with the
surrounding area.
7. Cut a piece of glass mat that is 25 mm (1 in)
larger than the entire repair area. Prepare a
mixture of catalyzed resin and soak the glass
mat in it. Lay the resin soaked mat over the
patched area and smooth it out with a spreader.
