Operating Instructions:
This tool operates on clean, dry, compressed air at regulated pressure at 40 - 80 PSI. Too low or too high pressure
will adversely affect the gun and the quality of spray.
Check and replace any damaged or worn parts on the tool. Make sure the trigger and nozzle can operate will.
Connect the gun to air supply. Be sure fluid cap, container and air hose should be connected tightly with spray gun.
When spraying, hold the gun perpendicular to spraying area, and then move it parallel several times. The trigger
should be locked before the stroke ended. Keep the appropriate distance of 6-12 inches between gun and surface
area, according to the atomization pressure and spraying conditions.

Gel Coat Troubleshooting Guide
Proper gel coat application is difficult for professionals and is probably the most common problem area for those new
to fiberglass work. Most common gel coat problems are related to temperature variation, catalyzation and a variety of
handling techniques. The following list of gel coat problems and causes should help to resolve some of the difficulties
associated with gel coat.
1. Wrinkles And Pinholes: A coating less than five mils thick may wrinkle, especially when brush marks are present.
Check the thickness using a gel coat thickness gauge. The preferred thickness is .010” to .020”. A wrinkle can also
occur if the gel coat is not cured enough prior to lay-up. Before lay-up check the surface for tack. The surface should
be sticky but not transfer to your finger. Several things can affect a slow cure; solvent or water entrapment, under
catalyzation, cold temperatures and other factors. If the gel coat film contains pinholes, check the spray equipment
for moisture in the air lines or dirt in the traps. It is also important to review your spray techniques.
2. Slow Gel Coat Cure: Any temperature below 70 degrees F will retard the gel time. An under-catalyzed gel coat will
also result in a slow cure but this is not a recommended technique for deliberately lengthening gel time. High
moisture and humidity will lengthen the gel time.
3. Sagging Of The Gel Coat: The most common reasons for gel coat sags would be when the gel coat is applied in an
excessively heavy application in one or more passes. To avoid sagging, spray in multiple light coats at a 15” distance
from the mold. The maximum thickness to be sprayed at one application is .016”.
4. Porosity: Gel coat porosity (air bubbles) is normally caused by trapped air or moisture. This can be prevented by
limiting the spray thickness per pass to .005”. It is also important to verify that the proper air pressure is being used
because an over pressurized spray can cause fine porosity. Air pressure should be set at 40-80 PSI, depending on
viscosity.
5. Separation Of Color: Most color separations are related to improper spray techniques. Reduce or lower thinning
agents and lower the per pass thickness of the gel coat. It is also important to avoid any spray overlap areas.
6. Discoloration On Finished Parts: This problem is caused from porosity related to air entrapment while spraying.
This can be overcome by spraying the mold surface with several light passes. It is also important to bleed any
moisture from the air lines and to be sure that the mold surface is dry.

Gel Coat Troubleshooting Guide, Continued
7. Craters And Pock Marks: These surface blemishes can be caused by improper resin to catalyst ratios and improper
air pressure both high and low. Another cause for craters would be oil or moisture on the surface of the mold.
8. Fisheyes: Fisheyes are usually caused by contaminates on the mold like dirt, moisture or oils. Bleeding the air lines
and using air filters will lower any air related contaminates. Try to isolate the spray area from any oils, especially
silicones.
9. Blisters When Immersed In Water: Blisters can be caused for the following reasons:
1. Incomplete cure
2. Improper wetting of the back up fibers
3. Bad bond between the gel coat and the back up laminate. This is often caused by contamination.
4. Thin gel coat
10. Lifting Of Gel Coat Before Laminating: This condition is usually related to shrinkage of the gel coat. Shrinkage can
be caused by:
1. Too fast of a curing time normally caused by over- catalyzation.
2. Delays between the gel coat and laminating can cause shrinking
3. Variations in gel coat thickness can vary the gel time which can cause shrinkage.
4. The mold surface is too hot.
11. Back Up Pattern Showing Through Gel Coat: This visual pattern is caused by too low a gel coat thickness or the
gel coat was not properly cured.
12. Gel Coat Sticking To The Part: This condition is caused by improper releasing of the mold surface. It is important
to use release agents formulated for the reinforced plastics industry. Proper training and common sense will
eliminate most of the problems associated with gel coats. Proper handling of gel coats will result in a part with a
blemish free surface.
