Water borne epoxy.
The above, of which details are below, has proved incredibly useful to me. All the work to date, on my TangaroaMk1, has been done while the boat is afloat. The biggest problem has been to keep the moisture content of timber and ply down to acceptable levels.
This,water borne epoxy, I use as a sealer. It is tolerant of damper timber than regular epoxy . A couple of coats within a half hour or so enable regular epoxy/fibre mixes to then be used for bonding etc. If I have to delay until this stuff has part cured, say next day, I abrade the water borne stuff with 40 grade grit.
I have lots of test pieces . I hope they do not fall apart just as I finish the boat!
Because it is water borne, I have experimented mixing it with latex paint. I have used it on the bottom of the boat's GRP punt. So far OK, after summer and early winter.
The stuff is: Resolcoat 1010, and is manufactured by REA Industrie, of Marseilles, France. The UK importer is
Connexion Technology of Bristol.
