International Gelshield 200 Osmosis Protection

Gelshield 200 is a quick-drying and easy-to-apply epoxy primer, that protects GRP against osmosis. You can use it down to just 5°C and as it’s fast drying, you can apply multiple coats in one day.

International Gelshield 200 is a specialized epoxy coating primarily designed for osmosis protection in fiberglass boat hulls. Here's a summary of its key features:

  1. Osmosis Prevention: Gelshield 200 is formulated to provide effective protection against osmosis, a phenomenon where water penetrates the gelcoat of fiberglass boats, leading to blistering and damage.

  2. Epoxy Barrier: It creates a durable epoxy barrier, preventing water penetration and safeguarding the hull against osmotic damage, enhancing the longevity of the boat.

  3. Moisture Resistance: The coating effectively resists moisture ingress, protecting the hull from the effects of prolonged water exposure.

  4. Adhesion & Compatibility: Gelshield 200 exhibits excellent adhesion to properly prepared fiberglass surfaces, ensuring a strong bond for long-lasting protection.

  5. Application & Versatility: It is designed for easy application, allowing for smooth and even coverage. It can be used as part of a system with other International Paint products for comprehensive hull protection.

International Gelshield 200 is a trusted solution for boat owners looking to prevent osmosis and preserve the structural integrity of fiberglass hulls. Its ability to create a protective barrier against moisture makes it a valuable asset in maintaining and prolonging the life of fiberglass boats.
