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.

  • 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.

This product is the best teak sealler


I use Semco on all my exterior teak on my trawler, and I have a lot. I have been using Semco for the last 20 years and always will

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.

Clean teak well first

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.

super penetrating


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.

I would buy again.


Like the results with two coats. Still may add another coat to retain color.

Good Teak Sealer for Outdoor Furniture


Product is fine and the shipping was quick -- i just wish the shipping and handling costs were less.


Portland, ME


New teak for old


Cleaned decks as reccommended, applied as directed, two coats. Teak looks great. Cleans off dirt and bird poop with rinse from hose. Good traction on deck, wet or dry. Easier to apply than expected. Easier to wipe off fiberglass and metal than expected. If it lasts four months (in Florida sun), I'll give it five stars, but it's too soon to tell about that.



Good product


Good product although two types of teak furniture - table, chairs - accepted finish quite differently. Better finish than oils. "Haz Mat fee" seems like a hidden cost.
