Don't sand first!
 
2 yrs now and parts of the toe rail cap rails (teak ) are turning gray and peeling. (Cetol Nat teak)

Started scraping the finish rather then sanding first. I've done this often on other projects like furniture. It gets allot of finish off before getting the sandpaper out.

Tools are simple hand held scrapers (red devil type) a file (to keep an edge on the scrapers) Card scrapers.

Only light pressure is needed to remove the finish, if you really need to press hard; the scraper needs sharpening.

Large smooth surfaces are more difficult and I'd use paint/varnish remover first.

I've used a heat gun to soften the Cetol up prior to using the scraper, works great. Might not need the heat in a warm climate.

Been there! With Cetol ! That stuff flakes and makes a mess. I suggest not re-applying.

I've left the toe rail and rub rail bare for the past year and like the grey oxidized look. It will need some cleaning this season, but that's it. If I dry spray some Tuf Enuf, mist with water and lightly scrub with a scotch pad, it will come back to new. I'll do the whole boat in an hour.

I keep the brightwork look on the cockpit coaming, the cockpit table and a couple of accents in the cockpit. All I need.

the toe rails are not very well respected by anyone boarding my boat. I'm actually very happy with the cetol Minn.

It's important to be happy!

deniseO30 is absolutely right.
Cetol comes up quite easily with a simple, gentle, mechanical scraping.
A little heat gun treatment can help soften up the finish.
Sand when most, or all of the finish is gone.

My teak is grey. After all, that's why they used teak, because you don't have to do anything to it. Every time I get the urge to use one of our rare sunny days to varnish, I usually go sailing instead. Some of my paint is peeling too. :)

Having said that, I sure do admire and appreciate the work others put into the appearance of their boats.

Denise, I am wondering why your finish needs replacing so soon? I am in CA, so a fair amount of sun, and after 3+ years things still look good (like you my toe rail is not treated as gently as it should be!)

I applied about 2 layers of Cetol natural teak, followed by a couple of layers of Cetol Clear; I have refinished with Cetol, two layers, each year. The only bad spots are where I had a chip or scuff which I did not fill, and got wet/weathered (duh) leading to a slightly different color. Given the abuse I give it, assuming you want to go shiny - and I have little choice as my teak is thinner than it was when she first swam - cetol stands up to abuse way better than varnish would!

Thanks for the tips on scraping. I have a few scrapers and that certainly seems the way to go, especially if warmed first.

I found that cetol will hold up best to UV if the clear gloss is applied over the original 3 coats of natural. At first I reasoned that going without the gloss would be best since the way I understood it is that gloss did not contain the UV inhibators. Now on the annual recoat I find that using the gloss gives better protection than just reapplying the natural.

Probably why I found it came up and flaked everywhere without any scraping. :)
