Teak deck rework

[Bill Ogilvie]

Looking for some advice from anyone who has redone a teak deck. I have a 1969 Cheoy Lee Offshore 27, fg hull, teak deck, teak & fg cabin roof. The deck leaks where it meets the cabin because the calking between the deck planks has cracks in it. I've pried most of it out and plan to use Life-Calk by Boatlife. Some of the seams, it turns out, were filled with tar. Most of the tar has been scraped out, but it's hard to get it all out. Will the tar interfere with the calk material if it's not all removed? Is it advisable to risk using a solvent to get more of the tar out?

Polysulphide

is the usual bedding compound for teak. Life-Caulk will do it, tho' not MY favourite brand.Very often the stuff used is black, so your existing might not be tar.As always, preparation & cleanliness are the key to a good seal.Regards,Gord

Removing tar

What is your favorite calk and have you had to use a solvent to remove undesirable calk material?

Favourites

I like 3-M and Sikkens Caulking/Bedding/Sealant products - but that's just my preference."Anti-Bond 2015" works OK on 5200 (Polyurethane). Can't remember who makes it?Automotive "Tar Remover" or Turpentine followed by a good rinse should do tar.Gord

Boatlife sells 2-part polysulfide kits that would do well. Go to their website and you will find a wealth of info-do it yourself. This should answer all your questions. Go the 2-part system,while it is a pain,it will give the best results. (less leaks-long term repair)

Thanks

Thanks for the advice and link. Has anyone done this recently? Did you have to remove all the old calk (polysulfide) and rout the grooves before applying new calk?

My experience is only with new construction not repair. When ever there is any questions or doubts we go to the manufacture of the product in question. They have invested $$$$ in the R&D of their products to minimize liability & poor results, otherwise you are blindly following the blind with inacurate information you may get from uninformed "dock talk".Best regards, Tim
