Deck Caulk

Postby Jimbob » Fri Dec 01, 2017 10:35 am

Hi Everybody,
I'm thinking ahead about the caulk to use on my decks. I'm not sure about using 3m 4200 as it was a real mess and not much working time, and cleanup was a problem, when I used it for the strut, etc. I have seen postings on using dap bathroom caulk which would seem to be easier to work with. Silicone in any caulk I would think would be a problem with trying to apply varnish over it.
What do you guys think? Any recommendations?
Thanks,
Jim

Thanks Bill!
After reading your link, I think I might go with the DAP latex caulk at the end of the article. Looks like what I was looking for (water base, easy cleanup, can varnish over it.)

I used the 3M 4000 UV. Better than the 4200 but messy and expensive. I have also use System Three Gel Magic with a white tint. Also messy and expensive.

Don Danenberg recommends Sikaflex 291 LOT (long open time, or slow setting) which can be found in white, black or mahogany brown colors if I remember correctly. He applies it AFTER staining and varnishing to make cleanup easier. He recommends sealing the seams with varnish to seal the wood from moisture and keep the caulking from soaking into the wood. When you get your varnish to a good gloss with just a coat or two to go, fill and tool the deck seams and wipe the deck clean. Doing it this way cuts down on time spent masking off the seams and still having the caulking go under the tape. When the deck seams have cured, apply your final coat or two of varnish to seal the deck seams and keep them clean.

Bill provided a great link on this post with what other glen l builders have done regarding deck seams. It is a glen l resource document. Garry Stout, in that link had a bad experience with sikaflex. He said it was difficult to work with and had to remove it (a 20 hour job) and then went with the DAP latex caulk. I think I will be following another amateur boat builder's advice on this one. I will follow Don Danenberg's advice of sealing with varnish first, and after the the top layers of varnish are on, following up with white bootstripe paint with a pinstriping machine.

I don't know why I didn't think about this before. I have plenty of planking scraps so I will be practicing my technique before I apply any caulk to the boat's deck. Sometimes I get anxious and jump right in rather that practicing.

I used the dap on my rc model glen l zip. It has been perfect and it went on very easily. I didn't even tape, just spread it in the joints,use a plastic spoon to spread it then as it dries clean the excess off the deck with water and a little solvent. I did not varnish over it. Did the caulk after the deck was completely varnished. I kinda wish I did the caulk on the full size Zip, I thought it would be difficult but it's easy.

I am inclined to use the Dap recipe for my deck but would prefer black. Does anyone have a suggestion for what I might add to get that color?

I used boatlife life caulk. It comes in black, mahogany, teak, or white. I used the white caulk on my boat. Goto Marine sells it in black.
The caulk was really nice to work with.
