Dr. Rot, thanks so much for you reply. Lots of very good stuff. Sounds like
very sage advice. I know where the majority of the leaking is. I is mostly
in the aft section. I the spring I always soak the bottom by watering the
bulge. The aft of the boat would make a great shower bath in the
beginnings. I tightens up after a few days but still leaks.
I will pull the floor boards and proceed per your advise. One question
however, how is caulking accomplished? Does it require a product you
supply? Some info regarding this operation would really be appreciated.
I agree, I don't want to spend the money to re hull the boat. Your products
sound fantastic. With them why would anyone ever re hull.
Thanks again for you reply. I really enjoyed hearing from you.
Well, if you know it's in the aft section mostly, then you could -- if
you want -- start a re-caulk job back there before you launch the boat.
What you do is define the area of the hull, say the aft 20 feet, and
call in a man who KNOWS how to re-caulk. Basically this is reefing out
each bottom plank seam of all material (cotton and caulking material),
letting it dry, coating all seams (and any punky looking wood) with
CPES, pounding in new cotton, and then finishing off the seams with a
polyurethane sealant, such as 3-M 4200. The polyurethane will bond with
the CPES and give you a good seal. Then paint the bottom and pitch her
back in the water.
You should also take a good look inside at the frames. Make sure they
are solid, no bad or questionable wood, and no big gaps between the
frames and the hull planks. If it were my boat, I would at the same time
soak all the inside frames with the CPES. This will seek out and help
seal any bad spots you might not be able to see. Just slosh it on with a
brush. Wear a mask capable of filtering organic fumes.
The real key here, Paul, is finding a good caulker. Wouldn't be a
problem here in Seattle, but I just don't know about Idaho. A bad
caulker can do a lot of damage by pounding in too much cotton too hard.
Ask around. You could do the final sealing with the polyurethane
yourself -- it's just a matter of gunning it in.
Yeah, our products are good and will do a lot, but sometimes .... Last
time we hauled DELTA we wanted to replace the stb'd rub rail, a 2 X 6
inch beam. Should be easy, but in fact the plank underneath was so far
gone that we had to pull the pieces that were left and install a new one
(or at least my son and nephew did, while I, old man that I am, stood
below and hoped for the best. They did a good job!).
At this point, the main product we sell that will be of interest to you
is the Clear Penetrating Epoxy Sealer. Down the road you might find use
for our Fill-It Epoxy putty, or resin, or adhesives/glues. But right now
it's the CPES. We'll work with you to make sure it gets done right.
Come back if you have more questions.
