Interlux® Watertite is a two-part epoxy filler, suited to most DIY repairs above and below water.
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 face mask.
Inspect for damage. Small repairs can be tackled easily, but any damage affecting a large area, or affecting the structure or hull integrity, should be referred to a professional for proper assessment.
Remove any loose filler or gelcoat and abrade edges to remove loose material. Remove all debris and prime with InterProtect® 2000E or Epoxy Primekote, according to system recommendations provided elsewhere in this guide. Apply Watertite or Interfill® after the first coat of primer.
Mask off the damaged area and apply Watertite using a putty knife or spatula. Allow to cure, following the recommendations provided on the product label.
Once cured, sand with 80-220 grit paper. The finished repair should be smooth and level with the surface. If required a second layer of filler may be applied, repeating the same process. The repaired area can then be primed, ready for painting.
