Re: Stus-List Low Viscosity Epoxy
Hi Sam, The penetrating epoxy is kinda volatile so you might have difficulty with a US firm shipping across the border. The two Canadian Manufacturers I like to deal with are Systems 3 and Industrial Formulators. They both started out in Lower Mainland area, B.C. My last purchase was System Three (regular epoxy as barrier coat under Inter 2000) 'cause they were cheaper :) https://systemthree.com/collections/rot-repair Did I mention I also have a wooden boat?

I didn't catch that part but what I do remember is that IIRC you had to mix the entire batch. Use it or loose it. At $20 its just a little too pricey to loose it.

Re: Stus-List Low Viscosity Epoxy
West Marine sells both Git Rot, and their own version which is essentially the same thing but at a lower price point. The WM version also comes in 2 different size kits, so you can buy an amount appropriate to the size of your project. Our local Lowes store also sells a penetrating epoxy kit with resin and hardener to make 16 oz of epoxy. Working time is supposed to be 60 minutes to allow penetration of the wood. So you might try a home improvement store or hardware store in your area if there is no marine chandlery/boat dealer in your area.

Stus-List Low viscosity Epoxy was Re: Subject: Re: Keel
Not an expert but I would mix a thickened batch of epoxy loaded with cab-o-sil and chopped glass, trowel it in place then set a fitted waxed-paper wrapped piece of stiff, flat, plastic on top, bored for the bolt holes, fitted to bilge, and spin on the the keel bolt until you get some squeeze out. radius the edges of the squeeze out with a tongue depressor or similar. When the epoxy gels, then give it a wipe with an acetone dampened rag, this will smooth/fair it. After it kicks remove the plastic piece and give it a light sand, then a coat of unfilled epoxy and it will have a glossy, easy to clean surface.Make sure you protect the keel bolts by wrapping it with waxed paper (several wraps). Make sure you prep the surface first. Dave Subject: Message-ID:Content-Type: text/plain; charset="utf-8" Not not hijack this tread, I changed the subject. Since we seem to have epoxy experts here.

Re: Stus-List Low viscosity Epoxy was Re: Subject: Re: Keel repair
Well, there aren't any absolute answers. Some solutions are just better than others. I like epoxy for injecting, flowing and uneven surfaces. It is much less viscous than most putties. It fills voids if you don't mix it too thick. Like many of us listers, the best technique is to coat the adhering surfaces with neat (unthickened) epoxy and then follow it with the thickened epoxy. Just last week I helped a boat owner fill a channel on his boat where the wood core had rotted out. We drilled a few holes on the top of the channel and injected thickened epoxy. We knew we had a good cavity fill when we saw the epoxy starting to show in the next hole in line. I use thickened epoxy for overbored deck penetrations through core. I usually coat the core with neat epoxy then inject thickened. I like thickened epoxy for creating radius fillet joints. Mix it to a mayonnaise consistency, slop it in the joint and shape it with the backside of a plastic spoon. I would also use it under the keel bolt washers or plates which started this whole discussion. I also use marine grade vinylester putty, a lot. Generally, I'm repairing shallow hull or deck damage where strength is not critical. There are two kinds, high strength and regular. The high strength is primarily know as a filler for blisters and shallow spots. The regular putty is used for fairing and smoothing and has little strength. Its primary advange is ease of sanding. I fill pinholes with marine grade glazing putty. Generally, I use vinylester under gelcoat. Vinylester putty doesn't flow well. Nor does it fill voids well. If the adhering surface is irregular, I try to sand or grind it to a flat or nearly flat surface prior to applying the putty. When I apply the putty, I am careful to apply it using strokes in several different directions. If you simply swipe it on in one direction, it tends to leave voids. I almost never use "kitty hair" vinylester products. I find they are hard to work with and leave lots of voids. Like Martin, I never use automotive grade products. When you use any of these products, you need to be mindful of getting a complete mixing of the product and activator while not creating a lot of bubbles in the mix. There are lots of little technique tips that you learn through experience. Dennis C.

Re: Stus-List Low viscosity Epoxy was Re: Subject: Re: Keel repair
I recommend a small amount of thickened epoxy under a piece of G10. If you use a low viscosity (read un-filled) epoxy it may not be reliable under the keel bolt clamping force. If I was performing the same repair on Calypso I would clean / roughen the area, butter in some thickened epoxy, place a layer of glass cloth or mat (to prevent squeezing out all the epoxy) and top it with the shaped G10. I would butter the bottom of the G10 with thickened epoxy. Add a little weight or clamping pressure to compress the lamination to the desired height checking to be sure it is close to parallel with the bottom of the nut. If there is a concern of epoxy bonding to the keel bolt or nut there are several mold release products and tapes available. Peel ply used in vacuum bagging can be very useful. Let me know if you go this route and need a small piece.

Re: Stus-List Low viscosity Epoxy was Re: Subject: Re: Keel repair
The best way to get a very level and flat surface is to use thin epoxy... But then it may squish or flow out and allow for voids. Besides that, you MAY want to create a damn around the keel bolts. I don't think crumbling is going to be a problem. The 12000 psi coming from the keel bolts is "pounds per square inch" . With a backer of stainless washer and G10 you're going to be spreading the load considerablythat is what the backers are for. As mentioned here before the west system epoxy compression stress is 11000 psi. Pretty close to 12000 even before spreading the load. Even if your backers were only 2x2" you'd be down to 3000 psi on the epoxy. I expect that the G10 will be 3-4 inches wide and as long as possible (~10" or more). 12000 divided by 40 square inches is only 300 psi.
