Getting that perfectly smooth, glossy gelcoat finish takes more than just the right product. Your technique is key! Here's a comprehensive look at the most popular methods, along with their pros and cons:

Methods for a Perfect Gelcoat Cure

With our TOPCOAT option, you can simplify your process, achieve a smooth (nearly) walk-away finish, and eliminate the need for PVA or wax!

• This additive is blended right into your gelcoat, creating a smooth, durable surface with minimal effort.
• Eliminates the need for time-consuming steps like applying PVA or sanding out imperfections.

• This time-tested method relies on adding a wax-like surfacing agent to your gelcoat (at a 4% ratio).
• As the gelcoat cures, the agent migrates to the surface, forming a barrier against air crucial for proper curing.
• It requires some light sanding after curing to achieve that high-gloss finish.

• Polyvinyl Alcohol (PVA) is a water-soluble film applied after your gelcoat cures.
• PVA prevents your cured gelcoat from sticking to the mold for clean separation.
• The downside is the extra application step and the need to wash off the PVA after demolding.

• Time-saving: Streamline your process and save precious time.
• Beginner-friendly: Great for DIYers and pros alike who want consistent, professional-grade results with minimal hassle.
• Cost-effective: Often a more affordable option in the long run, considering the time and materials saved.
