having lived in south florida for 25 years, and now central florida for 10 years, may i recommend to you what i consider the best teak treatment for the tropics. Starbrite Tropical Teak Oil
. notice i didn't say starbrite teak oil
. i said starbrite TROPICAL teak oil.
it's a high quality teak oil with an ultraviolet ray inhibitor in it. the teak oil penetrates the teak, as it should, and the uv inhibitor remains on the surface and protects the teak beneath it. i generally put on two coats every couple of years, although i've had it last as long as four years.
if you're starting with bare, clean teak, the work goes quickly. otherwise you should probably get rid of any old finish you have and get down to bare teak.
1. wash the teak. i like don casey's mixture; a bucket of water
with a half cup of liquid laundry
detergent and a half cup of bleach. brush it on (always brush across the grain, not with it), let it sit ten minutes, and hose it off. you're done cleaning
2. brush on one coat of STARBRITE TROPICAL TEAK OIL. then brush on a second. i advise you to tape around the teak or keep a rag with mineral spirits handy; if you get any on anything but the teak, wipe it off immediately or it's a pain to get if off later. i use cheap
but note that it seems to go through them pretty quickly so get a dozen. no need to sand between coats, by the way.
3. come back in two to four years and do it over again. you'll know when it needs to be redone because the finish gradually fades away. just repeat steps 1 and 2 and you're good for another couple of years.
it's available at west marine
and online. a can sells for about $30 to $40. there are two 'colors' available, a light teak and a 'regular' teak. the light teak definitely looks better. this picture was taken about a year or two after i applied it.
