How to Repair Gelcoat on a Boat: What Are the Steps?
Now that you have your supplies ready, let’s get into the how to repair gelcoat on a boat step-by-step method.
1. Assess the Damage
Before beginning, inspect the extent of the crack.

2. Clean the Area
Using acetone or a suitable solvent:
– Wipe the crack thoroughly to remove dirt and debris.
– Let it dry completely before proceeding. This step ensures proper adhesion of the new gelcoat.
3. Sand the Damaged Area
With sandpaper:
– Start with 80-grit paper to roughen the surface.
– Gradually move to 120-grit and then 320-grit to create a smooth surface.
The goal is to create a solid base for the new gelcoat to adhere to.
4. Mask the Surrounding Area
To prevent accidents:

– Make sure the tape lines are straight for a cleaner appearance.
5. Mix the Gelcoat
Following the repair kit’s instructions:
– Mix the gelcoat, hardener, and colorant.
– Make sure that you accurately measure the ingredients; improper mixing can affect the curing process.
6. Apply the Gelcoat
Using the plastic spreader:
– Apply the mixed gelcoat into the crack, ensuring it fills completely.
– Use your brush or roller for precision if the crack is small.
7. Let It Cure
Follow the instructions for the gelcoat to:
– Allow it to cure undisturbed. This can take anywhere from a few hours to a couple of days, depending on the brand and environmental conditions.
8. Sand the Repaired Area Smooth
Once cured:
– Lightly sand the area with 320-grit sandpaper until smooth and even with the surrounding gelcoat.
9. Polish the Finished Area
To restore the shine:
– Use a polishing compound and a soft cloth to buff the area to a high gloss finish.
