Repairing polyester below the waterline
A polyester boat needs specific treatment below the waterline. Polyester can deteriorate over the years due to osmosis or excessive growth of algae and organisms. This damages the gelcoat and, in a subsequent phase, your polyester laminate. You can repair this without any problems or also take preventive action by following the steps below:
Step 1: Cleaning the surface with the C1 bottom Cleaner
- This powerful cleaner will quickly and efficiently remove dirt, shells and hull fouling.
- Sand the surface thoroughly and make sure all loose parts have been removed.
- Allow the surface to dry sufficiently before moving to the next step
Step 2: Sealing the substrate with Epoxy Light primer
- Epoxy light primer has a very high resistance and is a good barrier to water.
- Apply one or two coats of a diluted layer of Epoxy Light primer to seal the substrate.
Step 3: Filling blemishes with Epoxy Filler
- Use an Epoxy filler to fill imperfections.
- For filling millimetres, you can use Epoxy Universal filler.
- For filling centimetres, it is better to apply the Epoxy Fiberglass filler.
- Finish by sanding with a fine sandpaper (e.g.: K 320)
Step 4: Application of waterproof protective coating with Epoxy Light primer
- Seal the surface waterproof with the minimum of 5 coats with the Epoxy Light primer.
- The epoxy primer also provides osmosis protection for several years.
Step 5: Finish with an antifouling
