The teak on my boat was previously treated with Cetol Light. Last treatment was just a bit over two years ago before I took ownership. It's past time for maintenance.

There are spots where the previous coatings have worn completely off and the teak is just beginning to weather gray. I don't think the spots are enough to warrant a full stripping, though, but not really sure how well it will take another coat. The only places of concern are some spots on the toe-rail, hand rails, and swim platform.

I'm planning to very lightly sand all of it, and sand just a bit more aggressively in the gray spots, then recoat with 2 coats. Does that sound about right? Am I asking for trouble with the bare spots?
 
Sounds about right. Get rid of the grey and be sure to feather the edges or you'll have a depression after you recoat. For the areas with base coat, just scuff them with a scotch brite vs. sanding them. I put two coats of Cetol Light on freshly sanded teak, then I scuff and put one new coat on per year. Looks great.

I recoated my Cetol light and sanded the rough areas and scuffed up the rest. It came out OK but I wish that I used teak cleaner on the grey before I sealed it.
 
Hmm, 32carv, did the gray area look bad when you were done, or did it just fail sooner, or what?

Brett, in your case were you able to get rid of the gray just by sanding?

Thanks.
 
The grey area doesn't look bad but I can see where it was. I doubt that anyone else will... but you know what I mean.
 
You should sand out all the grey and put on several extra coats to those grey areas to build them up before putting on your last two coats over all.
 
Joe,

Yes, sanding will take off the grey. I even sanded my previously untreated teak swim platform back to new wood--not too tough a job, and looks great!
