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.

I have 12 year old teak and recently cleaned with a two part cleaner and covered using the SEMCO product. I was looking for the newer teak look so I mixed 1 part natural with 4 parts gold. The product goes on with an orange color but softens as it dries. I was very pleased with cover and final color. Beware this does soften the black caulk between boards. The product dries to a dull finish. I applied one coat of the SEMCO clear coat over the sealer and ended up with a slight sheen to the finish very similar to freshly oiled teak. It has only been one month and the finish has held up great.

I used the Semco sealer on my teak swim platfrom for one season and was not happy with the durability of the product or with the unnatural color it gave to the teak. IT just didn't look good. I would not recommend this product. I think either varnish or oil provide a better look and superior durability.

        Comments about Semco Teak Sealer:

        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.

          Comments about Semco Teak Sealer:

          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.

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

                Comments about Semco Teak Sealer:

                Bought an older boat with decent but dirty and greyed out. Haven't had teak decks to care for before, so I did quite a bit of reading. All comments about the product were pretty favorable.

                You definitely need to deep clean the teak before you apply. A two-part cleaner - just this once - is the best choice. (I missed a spot and it shows.)

                The product is thin and runny. If you apply it with a brush, watch for drips. Keep it off fiberglass and metals (or wipe it clean before it dries). It goes on very quickly and is easy to spread. Flood it on and let it soak in. A second coat goes on immediately. It dries - or soaks in - quickly.

                If it lasts as promoted and protects over time as promoted, I'll be a five star user instead of just the four I've given it so far.
