First time users of gel coat can come across many problems with applying the gel coat. We will be doing a series of posts that describe the different issues and remedies for the various issues.


Dull of soft spots at random

Gel coat uneven

Poor breakup; Use three passes

Catalyst poorly mixed into either gel coat and/or laminate.

Mix catalyst thoroughly or make equipment adjustments for good catalyst mix.

Trapped solvent in gel coat and/or laminate.

Equipment surging in material pump and/or atomizing air. Improper catalyst settings (high or low). Gun held too close to mold


Trapped water in gel coat and/or laminate

Check cleaning procedure. Check catalyst level with equipment using solvent reduced catalyst.

Insufficient catalyst

Drain lines and correct the problem. Confirm correct catalyst concentration.
