FAQ - Osmosis
QuestionApart from blistering what other warning signs should I look out for?
Answer
  1. Star Crazing – This effect can occur where the gelcoat is brittle. Fine cracks usually form due to severe flexing or impact damage, allowing water to seep into the laminate.
  2. Pinholes – Tiny bubbles present in the gelcoat reduce its effectiveness and promote rapid water absorption.
  3. Prominent Fibres – Seen protruding beneath or through the gelcoat and can cause ‘wicking’ where water in drawn into the hull by capillary action.
  4. Under-curing of the Gelcoat - Incorrect mixing or application in unsuitable conditions can cause failure to cure properly. This results in porosity and may lead to water ingress.
