SAFETY PRECAUTIONS
Observe The Following When Making Repairs With
Fiberglass
1.
Avoid spilling the resin or hardener on skin or
clothing.
If this occurs, remove with paint thinner or
denatured alcohol.
Then wash with soap and water.
If the mixture contacts the eyes, flush thorough-ly
with water immediately.
Continue flushing for at
least 15 minutes and con-tact physician as soon as
possible.
2.
In some cases, some individuals may have skin
sensitivity to the use of these materials.
Because of
this, protective creams can be applied to the hands
to guard against irritation.
3.
When protective creams are not available, rubber
gloves may be used to protect the hands.
The
gloves can be removed quick-ly leaving the hands
clean for other work.
4.
When working with fiberglass always work in a well
ventilated area.
DO NOT SMOKE OR EXPOSE
FLAME WHERE KITS ARE BEING USED OR
STORED.
If possible, obtain a kit of material large
enough to accommodate only one or two jobs to
avoid storing any quantity of this material.
Resin
liquid must be kept in a metal container or cabinet
when not being used.
5.
Repairs must be ground or sanded to match
surrounding contours.
When grinding or sanding, it
is advisable to use an approved type respirator
during the opera-tion.
Suitable respirators are
available under equipment number SE-1798 and SE-
1799.
The ground dust or particles of resin or
fiberglass must not be inhaled, otherwise irritation
may occur.
REPAIRING FIBERGLASS
Small Holes (Under 3” Diameter):
1.
Remove damaged material such as loose
fiberglass and bevel the edges (approximately
20 degree).
See Fig. 2.
2.
Remove paint from outside surface with
sandpaper.
Clean inner surface (if accessible).
Fig 2.
3.
Cut a piece of cloth and a piece of mat so that the
patches will extend past the edges of the hole about
2”.
4.
Coat both inner and outer with resin mixture and
saturate both the mat and cloth.
5.
When tacky, apply the mat on the inner surface and
the cloth to the outer surface.
Press the two patches
together
using
polyethylene.
A
saucer-like
depression should be made.
See Fig. 3.
Fig. 3
6.
Allow the material to cure.
This is a chemical action
and not a drying action.
A hard surface indicates a
hard interior.
To hasten curing action, heat lamps
may be used about 18” from work.
Then smooth the
outside surface.
Additional coats of resin mixture
may be added if necessary.
7.
Apply plastic putty to fill the low spots, allow time for
the putty to cure, then smooth the outside surface.
Large Holes (Over 3” Diameter):
1.
Remove damaged material such as loose
fiberglass and bevel the edges (approximately
20 degree).
See Fig 2.
2.
Remove paint from the outside surface with
sandpaper.
Clean the inner surface also if it is
accessible.
3.
On a piece of polyethylene place a piece of cloth
cut larger than hole being repaired.
Saturate
with resin mixture.
Obtain a layer of mat cut
larger than the hole being repaired
