Resealing/Rechalking Teak Windows

[Aussie Mike]

G'Day all

I have a 1977 Clipper 30 which has teak windows fitted all around.

I'm keen to try and remove all the old sealant/chalking myself from around the inner and outer exterior frames to stop small amounts of water getting into the bilge after heavy rain.

I know I have to dig out all the old sealant before applying new sealant but was looking for any tips or tricks on how to do the job properly.

Also looking for recommendations on what sealant/chalking I should use once all the old sealant is removed.

Here is a link to some images of the windows.

Looking forward to your feedback
Thanks in advance
Mike

I think the only thorough way to do it is remove the frames. If you can see the teak "plugs" over the screws you drill those out then take out all the screws to remove the frames. My boat had the windows completely refurbished this way before I bought it. The frames were removed, all new window channels installed (for windows that move), then rebedded and varnished.

There is a caulk specially formulated for teak because of the high oil content of the wood.
I think it’s “Life Caulk”.

Resists oil, brine, gas, water and most chemicals. Bonds to wood, fiberglass, metal and glass. No priming required except on oily woods such as teak.

What do they mean by priming?

Life Caulk suggests the use of a primer that is applied to bare teak before applying the caulk. I use it, the Life Caulk and the primer first.

It is of course a Life Caulk primer.

Yes, I would completely remove the window frames and clean off all the old caulk. I just recaulked my teak decks with Teak Deck Systems 440 caulk. You might contact their support and see if they recommend it for your application. It is specifically made for teak. We did not have to prime before caulking just a wipedown with acetone. I have used Sika 291, I think, on my teak toerail to fiberglass joint. It has been on 2 years so far and no problems. We did follow the directions exactly and used their primer on the teak. The primer was $80 for a small container which had a shelf life of one year.
