FAQs
What is the shelf life of the gelcoat and catalyst?
Unopened gelcoat typically has a shelf life of 6-12 months when stored correctly. Catalyst has a shorter shelf life and should be stored as recommended. Always check batch dates.
How do I achieve a smooth, glossy finish?
Achieve a smooth finish through proper surface preparation, accurate mixing, even application with suitable tools, and potentially sanding and polishing after the gelcoat has fully cured.
Can this gelcoat be used for minor repairs?
While designed for larger jobs, it can be used for minor repairs. However, precise mixing is even more critical for small batches. For very small areas, specialized repair kits might offer easier handling.
What safety precautions should I take when using gelcoat?
Always use in a well-ventilated area. Wear appropriate personal protective equipment (PPE), including solvent-resistant gloves, eye protection, and a respirator suitable for organic vapors.
Can I tint this Brilliant White gelcoat?
Yes, compatible gelcoat pigments can be added to tint the white gelcoat. Ensure you use pigments specifically designed for polyester gelcoats and follow mixing guidelines.
How long does it take to cure?
Cure time varies significantly with temperature and humidity. At 20°C (68°F), it might be ready for sanding in 4-6 hours, but full hardness can take 24 hours or longer. Always refer to manufacturer guidelines.
Troubleshooting
Gelcoat is not hardening or curing properly
Ensure the catalyst was mixed in the correct ratio and thoroughly. Check the ambient temperature; curing is slower in cold conditions. Ensure the catalyst is not expired.
Surface is sticky or tacky after application
This often indicates insufficient catalyst or improper mixing. Apply a thin coat of PVA release agent once the initial cure has begun to prevent tackiness, or consider a post-cure sanding and polishing process.
Application is uneven or shows brush marks
Use a high-quality brush or roller suitable for gelcoat. Apply in thin, even coats, maintaining a wet edge to avoid overlapping marks. Sanding and re-coating may be necessary for a perfect finish.
Air bubbles are present in the finish
Avoid over-mixing the gelcoat and catalyst. Apply the gelcoat gently to minimize air entrapment. If bubbles are present after curing, they can often be filled and sanded smooth.

Setup, Compatibility & Care
Setup:
- Ensure the surface to be coated is clean, dry, and free from grease or contaminants. Prepare the surface by sanding if necessary.
- Carefully measure the gelcoat and the required amount of catalyst using the provided syringe. Follow the manufacturer's recommended mixing ratio (typically a few percent of catalyst to gelcoat).
- Mix thoroughly but avoid over-mixing, which can introduce air bubbles.
- Apply evenly using a brush or roller. Work in manageable sections.
Compatibility: This gelcoat is designed for use on cured fibreglass and polyester resins. It is not recommended for use on plastics, wood, or other materials without proper surface preparation and priming.
Care:
