Waterproofing?

[Simon DennettParticipant @simondennett54720]

Hi everyone,

I am building my first model, an Aerokits Sea Commander 34" Cabin Cruiser.

Once the hull skins are fitted the instructions recommend that "the entire inside surface of the hull should be sealed and waterproof with a two part epoxy resin."

Can someone please tell me what two part epoxy resin is, a brand and where to get it.

Thanks.

Simon.

This will tell you all about it. It's the best brand IMHO – trust me! Z-Poxy Resin You may find it marginally cheaper elsewhere.

Hello Simon and welcome to the forum

You are probably familiar with the resin sold in car shops etc to use with fibreglass matt, well that's Polyester resin. A liquid to which you add hardener. EPOXY resin is the same, other than its not polyester, but epoxy! Two part refers to the addition of a separate hardening agent.

I use "easy composites" for my glass supplies, but there's others…just do a search on ebay.

I am not sure if the kit really NEEDS a resin interior, or if its just a belt`n`braces thing. The resin will impart some extra strength and of course seal the wood, but there is nowt wrong with simply using varnish, or an Acrylic resin like Eze-Kote, which has the advantage of speed, easy clean up and low odour.

No doubt an expert will advise, because surely EVERYONE has built one of these??? (not me!)

Hi Simon,

Ashley is absolutely right oil based yacht varnish is fine for the inside of your Sea Commander, water based is in my view useless as it has no gap filling properties.
