One of the jobs in the workshop this week is commissioning this impressive new Merry Fisher 895 offshore. Destined for a long-standing customer upgrading to his third Merry Fisher, with power matched to twin 200 hp Yamaha outboards for effortless performance, along with a very high factory specification – including cabin air conditioning. One of the last jobs now being undertaken is a Gelshield 200 treatment (From International paints), a hull epoxy treatment upgrade.
Gelshield 200 is a quick drying and easy to apply epoxy primer, that protects GRP against ingress of water which can cause Osmosis. (Omosis is the movement of water or other solvent through a membrane from a region of low solute concentration to a region of high solute concentration. Osmosis is passive transport, meaning it does not require energy to be applied. From a nautical stand point, GRP over a long period of time can absorb a small amount of moisture. This process can be accelerated when the GRP is stressed – such as boat hulls that are caught in frozen water, etc.)
Gelshield 200 from a workshop point of view is very easy to use. It can be applied in temperatures down to just 5°C and as it’s very fast drying, you can apply multiple coats in one day (good to know as five coats are required). Cleverly, it is also provided in two shades (green and grey) to ensure consistent and complete coverage.
Preparation is straight forward as well on new boats with a wash down using Super Cleaner, then rinse with fresh water and allow to dry. Then lightly sand with 180 grade (grit) paper to provide an initial key for the first coat. Then simply apply the required number of coats, detailed in the specification sheets (minimum 250 microns DFT). As mentioned, by alternating the grey and green colours, you can ensure consistency starting and ending with grey. Mixing the epoxy is easy as well – just stir or shake individual components thoroughly. Add Curing Agent to the base, stir and leave for 10 minutes to allow bubbles to disperse.
Once the last coat is on and had plenty of time to cure then we will go on with the final antifoul coat as normal.
So, this Merry Fisher should have plenty of life in her, even when she’s onto her next owner several years down the line!
Gelshield 200 – adding protection and adding value!
