Osmosis Protection

What is Osmosis in GRP?

The gel coat on your boat is designed to prevent water from entering into the laminate. However, through age and wear or poor attention to conditions of manufacture, water may pass the barrier initially provided by the gel coat.

Osmosis in GRP is a degradation of the structure of the hull caused by ingress of water. It is noticeable by the formation of blisters on the gel coat.

Eventually, it may affect the performance of the boat due to the extra weight of the water carried into the laminate, and if ignored it may cause severe damage to the structure of the laminate.

What is Gel-Gard™?

Gel-Gard ™  provides high performance protection against osmosis for GRP. It is a professionally applied, high build, 100% solids, solvent free epoxy resin.  

HIGH BUILD EPOXY

Gel-Gard ™ builds an effective waterproof barrier.

SOLVENT FREE

Gel-Gard ™ does not release greenhouse gasses.

100% SOLIDS

For a thickness of 300 microns, Gel-Gard ™ is quicker to apply than its solvent based competitors.

 

COMPLETE SCHEME
 

Gel-Gard ™ complements perfectly the long term, maintenance free antifouling protection provided by Cuprotect ® .

 

PROFESSIONALLY APPLIED

 

Gel-Gard ™ can be applied by all Ecosea Approved Installers.

APPLICATION


Preparation involves removing all antifouling paints, lightly abrading the gel coat to create a mechanical key and masking the waterline and skin fittings.

The first layer of Gel-Gard ™ is applied with rollers to 100 microns thickness (100% solids).

The second layer of Gel-Gard ™ is also applied with rollers to 100 microns thickness (100% solids), wet on tacky.

For a complete underwater protection, follow with the complete Cuprotect ® scheme (primer, binder and granules).

Alternatively, apply a third layer of Gel-Gard ™ wet on tacky for a total thickness of 300 microns and follow with a traditional antifouling paint.

For best results, allow a curing time of 7 days.
