Blister Repair and Prevention

Step 1: Health and Safety

Before commencing preparatory work, ensure the area you are working in is adequately ventilated. Ensure you are wearing the correct PPE; we recommend safety glasses, goggles or visors, nitrile rubber gloves, overalls (ensuring skin is not exposed) and a solvent mask.

Step 2: Preparation

Remove all contamination from the surface using Fiberglass Solvent Wash 202 or Fiberglass Surface Prep YMA601. Sand using 80-grit sandpaper. Remove the sanding residue using Fiberglass Solvent Wash 202

If your hull is new, proceed to Step 4.

Step 3: Inspection

Inspect the gelcoat for signs of damage or cracking. Small defects can be repaired with Watertite Epoxy Filler following the instructions on the product label.

If more extensive damage is found or suspected we recommend that you seek the advice of a professional surveyor before continuing.

Step 4: Application

Apply InterProtect 2000E, building up to minimum dry film thickness of 10 mils (this will typically take 5 coats) using a brush or roller. For ease, alternate between the gray and white shades.
