Waterproofing my wooden hull

Just a word of warning, even after coating inside with resin there still a chance of water getting into interior and soaking into wood, it will find even the smallest gap, not matter how good your seal is, so after a sailing session check inside for any H2O and remove, then leave hatches or covers off so any small amounts can dry naturally. I have a few wooden boats balsa and ply some 30 to 40 years old still in good nick, doing the above. Have only lost one boat a Scratchbuilt Bismarck (one of my earlier attempts), to wet rot and that was after I'd store in garden shed, that over winter developed a leaky roof. Went to pick it up and bottom just fell off arrgghh!!. Rescued running gear which is now powering my brothers "Bismarck" (one of those Magazine kits, you know a bit each month, must have cost someone a fortune) he been given for nought, lucky beggar, did try to prise it from him, no chance :-)

HI Mate.

Notice you are in Bexhill so calling in to Easycomposites, they are in Stoke on Trent, is out of the question, no worries they have a superb mailorder site, it also has how to vidios that are good to watch.

As your model is the Sea Scout its small enough to use the stocking, please ask first, dont want your good lady ripping me appart, LOL. Tights are just as good, use to layers, one on then let it dry etc.

www.easycomposites.co.uk I bought the AT30 fast hardener withEL2 Laminating resin, this gives about 30 mins working time.

They also do brushes, thinners, mixing pots, glass cloth in different weights. I use the lightest .7oz, everything you need is on the web site.

Best if you weigh the resin and hardener, it is mesured as a ratio, 100 - 30. I bought two sets of digital scales, guess why!!!!!

It is a messy job but not a lot of smell, Poundshop for plastic gloves.

Good morning Mark and thanks for your quick reponse. The boat is an "Aerokits" Sea Scout kit (c 1950). I like the idea of using a stocking but can you recommend a supplier for the resin and glass cloth. Just one coat on the hull's exterior?

HI Mate

Several questions first. is the boat new?? if so you can coat the inside of the hull with thinned resin, use meths as a thinner, put small amount into the hull and gently roll the hull to spread the epoxy, remove any excess then allow to harden. Coating the inside as well makes sure the wood is not affected by any water sepage. Glassing the outside allows for the inevitable contacts with the bank or landing stage.

2. How large is the boat? small boats about 24" you can use stocking stretched over the hull then brush epoxy through the stocking, allow to dry and recote. larger hulls use light weight glass cloth, a single layer epoxied on in sections, several coats alow to dry between coats.

3. You mention Z-poxy, this is quite expensive, have a look at easycomposites web site, they do all the bits Resin, Glass cloth etc, also mail order.

Hope this helps

Waterproofing my wooden hull

Can someone please advise on the use of Z-poxy resin for waterproofing my wooden model boat hull. Should I apply JUST the resin to the exterior or Interior of the hull or should It be used In conjunction with fibre glass cloth layered on the outside surfaces.

Many thanks.
