Bottom job

Post by tikvah59 »

OK, it's not a sailing day, so I'll actually post some pictures of my latest project. This spring I removed all the paint from the bottom, patched the chips I found, and applied new paint.

Some details first:
  • - The bottom paint was chipping off in numerous places, leading me to think that the bottom layer(s) of paint were failing.
    - I chose to use Aquastrip because it didn't have toxic fumes, and Jamestown had it on sale. Practical Sailor and the online reviews seemed to think it worked OK.
    - I ended up using about twice the recommended amount, mostly due to user error. If I was to do this again I'd consider using this product, although given the time involved I would be seriously tempted to pay someone to soda blast the paint off.
    - Once I had the paint off I went around and chipped off little chunks of gel coat where it looked like it was ready to come off. Some spots are highlighted in the pictures. Then I filled with 3M and Evercoat fillers. I left the filler a little proud of the hull when sanding to avoid taking off too much of the surrounding gel coat.
    - I had a gallon of Shark White (tan, really) Micron CSC that I used for the first coat. I covered that with some West Marine ablative in blue. The goal is to be able to know when it's time to recoat by seeing when the lighter color shows through.
Here are some pix:

Image
Port side after first (maybe second?) application of stripper. It was probably too cold that day and it wasn't until I finished the job that I figured out just how long to leave the stuff on.

Port side aft.

Detail of chips.

Image
This is a section of the false keel. Looks like water got inside at some point and created a fishscale pattern of cracks in the gel coat. In the interest of time, I covered it with filler. There are probably a number of more thorough solutions I could have applied, but my thinking is that if it made it through 50 years it will most likely make it a few more.

Image
After the third (?) application of stripper. I kind of lost count . . . I didn't do the whole hull each time, though.

Image
Starboard side aft. You can see the joint between the false keel and the hull itself - it's the darker blue line (bottom paint that has yet to come off). Below that is a section where I believe a repair was done by wrapping fiberglass around the bottom of the false keel and up each side. It's the straighter line below the false keel joint.

Image
This shows the hull after sanding and filling is done. I've started painting with the first coat of bottom paint. The painted areas are where I'm going to move the stands to the next morning.

Image
Port side, next day. The stands have been moved and I've masked where the bottom paint will come up to.

Image
Starboard side aft, same time.

After the first coat of bottom paint.

Image
Starboard side after the second coat of bottom paint and after masking for the new boot top stripe. I changed the configuration of the stripe from where a previous owner had raised it to. He had simply measured 2" or so above the top of the original stripe, which means it curves up at each end but didn't really widen enough to look right. I measured up from the original waterline for the bottom edge of the new stripe, and then used the top of the original stripe as a guide for the new one.

Port side.

All done and ready to launch!

The stern. I didn't get the very end of the stripe quite right, but it's good enough for this year.

What did you use for the non-skid? I want to change the color of mine - right now the entire deck surface is plain white, but I like the look of the white deck with tan non-skid.

Me too. I used Interlux Interdeck. 1 part, easy to use, creates a nice non-skid surface, 4 years and still looks good. Easy to re-coat when the time comes. I see no reason to make the project more complicated.

I used Durabak. It's a polyurethane with suspended rubber particles. There are a number of sources on the web including: http://www.durabakcompany.com/.

I'm satisfied with it for the most part. As with any fancy paint it seems like you just figure out how to apply as you're finishing the last coat. This stuff sets up really fast so you have to do two or three quick coats then pull off the masking. I waited too long before pulling up the masking tape and had to cut through the paint to get it off. Two other problems: I didn't prime enough underneath (priming isn't required) so the blackish color of the fiberglass showed through in parts. Also, you have to rough up the surface well before painting, especially near the edges. I have a bit of peeling/chipping near the edges because I didn't rough them up enough.

Otherwise, it's really good non-skid and seems to be durable. Someday I'll probably lay down another coat because it will be easier than starting from scratch. It's comfortable to walk on barefoot and kneeling on it tolerable (it may be less so after another coat).

Let me know if you have other questions I can help with.

Did I mention that's the original 1959/60 gelcoat on the topsides? Great from 10 feet or more . . .
