Description

Our Osmosis Rot Repair Kit contains all of the products required to cure Osmosis Blistering on GRP Hulls, including our recommended high build epoxy paint.

Coverage of Our Osmosis Rot Repair Kit

This will clearly depend upon the extent of the Osmosis Rot that is affecting your fibreglass hull. The example pictured above is particularly nasty.

Coverage of CPES and Fill-It for repairing Osmosis Blisters

As an initial estimate we would recommend that you budget on a 2 US Gallon pack of CPES and a 1 US Gallon pack of Fill-It Epoxy filler for every 10 square metres of GRP that is affected by Osmosis rot. The worst affected hulls may use twice this amount, and the least affected hulls far less.

We will happily take back any unopened product that is returned to us in fit condition for resale, so feel free to purchase these products (CPES and Fill-It) on a sale or return basis if you are unsure of your ultimate requirements.

Sufficient black pigment to mix the filler thoroughly will be supplied free of charge with all osmosis rot repair kits.

Coverage of International Interprotect when curing Osmosis Rot

International Interprotect covers at up to 8 square metres / litre for a single coat.

Around 40 square metres of hull can be treated with one 5l can of white and a 5l can of grey, offering the contrasting colours between coats.

Interprotect Stock and Supply Timing

Please note that we do not stock International Interprotect but buy it to order.

We can normally fulfil orders within 3 working days of an order being placed. It is an optional part of our osmosis rot repair kit, and you may source it locally if required.
