Semco Teak Sealer

Semco teak sealer waterproofs and protects teak. This durable protectant maintains a protective coating through winter, eliminating the need for deep cleaning. Semco teak wood sealant goes on easy, dries quickly, and provides a non-slip finish.

Keeping exposed teak looking its best is challenging. Varnishes aren't ideal as the natural oils in this wood can cause blistering or peeling. Most common teak protectants are solvent and linseed oil based, and oxidize over time. The oxidization of surface oils causes teak wood to appear weathered or gray.

Semco teak sealer contains UV protection and a mildewcide to eliminate these problems. It can also be used to seal other woods such as cedar, oak, and pine, though you will need to varnish over it on those woods to achieve a glossy finish.

Choose from three popular shades: Cleartone, Natural, and Goldtone.

  • Many sealers promise to protect wood and repel water. Semco does it without the side effect of creating a slippery surface.
  • Withstands staining, weathering and discoloring up to a year.
  • Because the treatment is easily renewed and usually lasts a season, you won't have to endure tedious deep cleaning normally associated with teak restoration
  • Manufacturer coverage specifications: 1 gallon Coverage is approx 200 sq ft for 1st coat or 400 sq ft for the 2nd coat.
  • Cleartone contains no pigment, looks like oil, and is not as weather resistant as the other shades.
  • Natural imparts a golden-tan glow to the wood that resembles slightly weathered teak.
  • Goldtone produces the reddish-brown luster of teak that has been freshly sanded.

I would buy this product again.


Very easy to apply with a rag.


Englewood, Florida


I have used this product on my teak for years now !!


We have a 1963 Rybovich teak with fore deck & cockpit (motoryacht)..Now I use Clear Color on my new deck (about 10 years old now) when I had the older deck (god knows how old) I used a combo of natural & clear to enhance the color..if you really like color add some gold ..often people use gold & complain about too much color. Give it a day or two before you see true finish. Deck always looks like there is no product on it and never gets black and is not slippery..It is easy to put on with a rag like water. It can be re-coated immediately. Can be cleaned & re-coated mid year or just let it go to a light gray which is also nice ( My husband like grey & I tan so it is a good compromise through the season. I do sand each season to reduce the hard wood & prevent trapping water. I don't find it damaging the black caulking ..

Waist of time and money


We applied 3 coats front and back of a brand new unfinished Teak patio table & chairs looked great but didn't last the first time it was rained on it discolored the second rain black mold formed in several places after re-sanding we applied Teak oil has held up 100 times belter and was a lot cheaper.

I would buy this product again.


Reppeals coal dust from the pier up wind of my boat. When using teak oil, it constantly needed cleaning. Other varnish like products covered up the grain of the wood and after a couple of years would need to be stripped with a scrapper.

used semco on aged weathered teak. sanded off gray and applied product. super penetrating action, seemed to be really thin, but after six months it continues to be very protective and water beads and rolls off.I would use this again.
