Osmosis Treatments

By osmosis, water can enter the hull of a vessel through the gel coat.  When this happens, there is a reaction behind the gel coat creating pressure which causes blisters and eventually cracking. Once this happens, the underlying laminate absorbs water like a sponge, which then starts to compromise the hull.

We can help you protect against this with an osmosis treatment, in which we will:

  • Strip off the old gel coat
  • Clean the surface area of the hull to remove surface osmotic impurities
  • Dry the hull to a recognised standard
  • Fill and coat the hull
  • Apply antifoul to the hull
