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:

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.

Comments about Semco Teak Sealer:

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.

        Comments about Semco Teak Sealer:

        My rosewood veneer decks are sexy. I keep my melonseed covered when not in use, and I strip off the cover and give her a good scrub, then brush on and scrub in Semco with a rag. It is a very transparent finish but protects like crazy.

              Product seals, but leaves teak natural appearance.
              Particularly useful on sailboats as this product does not make deck/cockpits slicker than bare teak, when wet.

                Comments about Semco Teak Sealer:

                I didn't want to have to varnish all the teak on my Westsail 32 (teak decks, etc.) but didn't like the dirty, worn, shabby look of just weathered teak. I sprayed the wetted teak with Tilex, wiped it around with my hand, let sit for five minutes and then scrubbed the teak clean with a plastic kitchen scouring pad. The difference was amazing, but then applied the SEMCO gold to the teak with a small sponge brush, being careful to wipe most of the watery SEMCO off in the can, then brushed on three coats. The teak looks like new wood and has been through several rainstorms and Florida sun for a couple of weeks and still looks great. Hopefully it will last at least six months. The SEMCO soaks in, doesn't build up, and water does beadsup on it. Great so far.

                  Follow the directions and it works as advertised.
                  in the Spring, I clean the teak with Comet cleanser and apply three coats of SEMCO Gold tone. By September (In the Chesapeake Area) you need to apply another coat. If you want less work in the Spring, apply a couple coats. Great stuff made here in Maryland.
