Quick facts
- First step
- Record the visible issue and the actual process facts
- Do not assume
- A single visible defect proves one root cause or a material fault
- Compare against
- The specific product TDS, batch, storage and process records
- Keep controlled
- Do not alter catalyst or other inputs by guesswork
Treat the visible result as a signal
Peeling, cracking, pinholes, fisheyes, tackiness or other surface variation should be treated as a signal to investigate, not as proof of one universal cause. An FRP surface depends on the mould, the surface-coating material, the application sequence, cure conditions and the laminate built behind it.
Record the concern before changing the process
For peeling or adhesion concerns
Record the mould condition and preparation, application sequence, batch, cure timing, component and photographs. Avoid assuming the visible separation identifies a material cause without the full record.
For cracking or crazing concerns
Record where and when the result appeared, the component geometry, moulding sequence, laminate build-up, cure history and service context. A surface appearance alone cannot establish the cause.
For pinholes, fisheyes or other surface-pattern concerns
Record the mould condition and preparation, application method, batch, storage history, ambient conditions, timing and photographs of the pattern. Avoid assuming that one visible pattern identifies a material cause without the full record.
For tackiness concerns
Record the gel and cure timing, batch, ambient conditions, storage history and all process inputs. Compare the documented process with the specific TDS rather than copying a catalyst practice from another grade.
Keep corrective actions controlled
Do not add chemicals or change catalyst, accelerator or process inputs by guesswork. Handling and cure requirements are product-specific. A controlled review of the product data and the actual records is safer and more useful than a generic corrective instruction.
Prepare a useful technical discussion
Share the product and batch, component, moulding method, preparation, process timing, ambient conditions, storage history, photographs and the observed result. This allows the conversation to focus on verifiable facts without offering unsupported repair claims.
Frequently asked questions
Does peeling prove that the Gelcoat Resin is defective?
No. A visible result can involve mould condition, preparation, material condition, storage, process sequence, cure conditions or the complete FRP build-up. Record facts before drawing a conclusion.
Should a team change catalyst dosage to correct tackiness or cracking?
Do not make unapproved changes by guesswork. Follow the specific product TDS and obtain technical guidance based on the actual process and batch.
Do pinholes or fisheyes identify one cause?
No. Record the mould condition, preparation, application method, batch, storage history, ambient conditions and observed pattern before drawing a conclusion or changing the process.
What should be shared for a troubleshooting discussion?
Share the product and batch, component, moulding sequence, ambient conditions, storage history, timing, photographs and the observed result.
