Finally, an update. Sorry about the lapse in updating, but life got in the way of my woodworking fun. On the last blog I patched the two spots that had bubbled. Now it’s time to sand them and make them disappear (hopefully). First order of business, put on some 80 grit. Now sand off the dry cloth, both sides. Here this is before and after.

Next I like to sand off all I dare to so that it more or less just covers the hole. If I leave too much cloth around the hole it may leave a bump you will be able to feel, even after you feather the edges. Here are both sides sanded to suit me.

Now it’s time to sand and reshape the points. I like to do this the old fashioned way, by hand.

Here’s a before and after of that.

So the bubbles are patched, the patches are sanded, the points are ready, now to see if I did a good enough job. The best way to tell is to wipe the area with a wet rag and see if it disappears.

I think that is good enough. Now I will add more epoxy to it when I coat the whole hull, which is up after a thorough sanding with 80 grit. Here we go again.

Here is the area that I couldn’t sand the other day because it was too cold to cure overnight. Now it is cured and sanding out much better.

A word about sanding. This epoxy is extremely hard, and eats up paper quicker than bare wood. I have a problem with changing it when it needs it. I come to realize that it is taking longer than it should to do an area. It just dulls over time and I don’t notice it. I like to change paper after I’ve sanded about a third of the hull. Here it is done and all white again.

Now I have added what I hope is the final filler coat of epoxy. I use a roller for this, it has a foam pad with a 3/16 nap. It works great, but leaves small bubbles or an orange peel look. If anyone knows a better way to add this coat without the rough finish please let me know. I’m willing to try new ideas. It’s not the end of the world, it just makes for more sanding to smooth it up.

Well, that’s it for now. If my wife continues to do well I’ll get into the shop more in the future. As always, I’ll keep you posted. Maybe even tomorrow. See you then.

That’s a good looking patch Job!! Hope it sands out well this time. I’ve never had any cloth fill with two coats.

Good luck and thanks for sharing.

Hi Jeff,
Looking great. The only thing I’ve read about rolling on epoxy, is that you have to work slowly. If you roll on too fast, you whip air into the epoxy and end up with bubbles. Tipping with a dry foam brush may also help level the surface, but you did that before.

Jim, I do roll pretty fast, I don’t want the mix to harden on me. I will have to try to make smaller batches and slow down and see if that will help. I know that air in the mix is bad. If nothing else, i can try tipping again. Thanks for the help.
