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.

Water-based, environmentally-friendly sealer
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.

Questions & Answers about Semco Teak Sealer:
2013-04-03DARRYL KUNTZ asked: I've stripped all my teak and applied three coats of clear teak sealer. Now, just a week later I'm noticing some salt water spots on the teak, even though I have washed down the boat after every sail. How much coverage does it require.....and can it withstand the elements very well? Thanks.
+Expand Answers
2013-04-04BRIAN HAWTHORNTHWAITE: Sorry to hear about your problem. At the time I had a motor yacht and never had any salt water spots on the deck. Whenever I moved the boat, I always washed it down from bow to stern. This is good practice, regardless of sail or power.
2013-04-05MANNY SIVERIO: I've used Semco for many years with great results. I've found that the clear does not offer great UV protection, and the other two colors were not to my liking, so I mixed them 50-50% to get our color.
Semco is a bit different in that it's absorbed by the teak and prevents water intrusion, unlike other products like Cetol. In the beginning, it took several coats to get the teak sealed. Eventually, the protection wears off so long term, we coat our deck twice a year and it works great.
Semco is not for everybody, though. Some like to leave their teak weathered, some like it completely sealed with a varnish-like product and some, like me, like to see it blush and protected. Hope this helps.
2012-11-06A shopper asked: Does it work well on teak furniture?
+Expand Answers
2012-11-07JOHN BALTZEGAR: I have only used it on my boat but I suspect it will work just fine on furniture.
2012-11-07EUGENE TERRENZI: I have only used it on my boat teak, but I see no reason why it would not be
good on furniture
2012-11-07JENIFER SNOOK: You can use it on teak furniture. I used it on my teak outdoor furniture set and it worked pretty well. It's a little different than other sealers. Other sealers have oil in them and does make the furniture look nice. However, oil can lead to mold so this is supposed to seal without contributing to mold. I can't tell you if it worked because I've used both types of sealers and we have developed some mold in our furniture.
2012-11-07STEVEN KASARJIAN: Yes. Teak is teak. You must remember to pre-clean the teak and sand down all rough, open grain surfaces prior to applying Semco sealer. If your furniture is new, this will not be necessary. Also, make sure your furniture really is teak. Remember this is an oil base product and has a significant odor during application and a significant odor after application. If your furniture includes seating surfaces, there will be a period of time where color transfer to clothing can occur. My recommendation would be to use Semco outside and let the furniture sun dry and air dry for several days before use. If there is a breeze during the drying phase, even better.
It is an incredible product and I would never use anything else on the teak on my boat, and I have a lot of teak. There is never any peeling and surfaces are never slippery. I hope this helps. Contact Semco if you need more information. They are extremely helpful.
2012-11-07JAMES C WELLER: Yes. It lasts about 6 months when in the sun. It is easy to apply and reapply. It is not an oil so it won't stain your shorts. I've tried every type of teak coating and have stuck with this for the past 11 years.
2012-11-07WILLIAM MACFIE: Absolutely....I've got teak furniture on a screened in porch and used to seal right after I got it about 4 years ago and resealed it again this summer. Probably would have lasted longer, but I hadn't been covering the furniture over the winter or taking inside.
I know it might seem expensive, but really does the job. I applied with both brush and using a plastic spray bottle...however, if using with spray bottle, wear a respirator!
Highly recommended....
2012-11-08NORIKO IWAMOTO: I bought the Semco Teak Sealer and apply on my garden furniture once a year. It has a pungent smell to work with but it absorbs well and the smell disappears after a while. It keeps my furniture in good condition all through the year. It will be many more years till the furniture turns to the deteriorated grey color. I recommend it.

2012-08-22WILLIAM GRENIER: I love the product and think it will work fine as I have used it on teak and some other woods (not cypress) with great success. Only my opinion but it seems this would be a good question for the manufacturer.
2012-08-22JIM HABERLY: This is a very good question. Semco is a family owned business and they're very helpful. The phone numbers are on the home page at the
semcoteakproducts dot com web site.
2012-08-24EUGENE TERRENZI: I really have no idea. I have used Semco on teak for several years, but never on any other wood. Why not ask Semco directly.

2012-08-07JOHN SCANLON: I used the Semco sealer on my teak swim platform and did not have good results. Like you, it seemed that it needed to be treated fequently to look good. I also did not care for the color.
Recently I have used Schooner varnish on teak ( although not on the swim platform - went back to oil there) and have been very pleased. Varnish needs to be maintined annually, but looks stunning. It has UV protection, and the outdoor boarding steps I varnished still look great after two seasons without any touchup. Will probably recoat this winter though. Hope it helps.
2012-08-08aileen willoughby: hi john - thank you so much for the tips - we'll take a look at the Schooner product too - hopefully we can stay away from the varnish because my understanding is "once on, never off" -
2012-08-08GARY MERTL: I'm in the Pacific Northwest so we have completely different climates. However, I think that if you followed the application instructions closely, you really shouldn't have experienced those results. Perhaps there was something in/on the wood prior to applying the Semco (??). You might want to contact the Mfg on that. I've found them most helpful.
Gary
2012-08-08aileen willoughby: thank you gary - we appreciate the reply - we did not use a teak cleaner first, just scrubbed the wood w/ detergent and probably simple green - think this time we'll try the semco teak cleaner first, then the oil and see what happens - we hate giving up on the product because it makes the wood look brand new - have you ever applied anything to the top of the semco to help seal it in without using a varnish?
2012-12-29GARY MERTL: The Semco cleaner will make a huge difference. You'll be pleased. I haven't put anything on top of the Semco. I slap on a fresh coat each Spring and it lasts me throughout the year. I keep the boat in the water year-round so it get constant exposure too.
2012-07-05BYRON WHITE asked: What is the difference between clear and natural ? Does the natural contain a color additive ?
+Expand Answers
2012-07-10ROBERT BECKSTEAD: NATURAL does contain pigment although it is not as vivid or color-altering as the other tones.
ClearTONE is pigment free and less resilient (less protective & wears off faster) than the pigmented tones.
Clear COAT is pigment free, but will slightly darken the wood - it produces a glossier, harder, more protective finish more akin to a varnish.
2012-07-10ROBERT FLOCK: Yes, the natural has a light blonde/tan color.
2012-07-10ALLAN STAHLE: It is our experience that the "natural" restores the (as the name implies) the more natural color of teak wood...there is some color. We have not used the clear and have no experience, but can only imagine that it has no color additives.
2012-07-11PETER LEADEM: The Natural Semco has a golden brown tone to it. I wanted my teak to stay looking like teak and the Semco performed great. The finish w/ Semco did not weather and turn gray. The pigment is semi transparent and did not distort the grain of the teak.
2012-07-11WILLIAM LONGSTRETH: I combine the natural and the gold, 50/50. That gives the teak a slight "honey" tone that looks like freshly cleaned and oiled teak. Both have a tint, but the gold tint is much more evident. You have to stir the mix occasionally to keep the tint in solution. After storing, it will settle out, like most paints. I have never used the clear, but I imagine it has no tint. I do love the product & have stripped all my rails and exterior teak trim down to bare wood. I seal the deck and the rest, using a rag for quick application. I takes me about 90 minutes to due the deck on my 42' Grand Banks. Bill
2012-06-28ROCIO MATAJIRA asked: I have a question, I want to use this product for a patio redwood deck..... is it a good idea? thanks for your help
+Expand Answers
2012-06-29ROBERT JENSEN: I like how the Semco Teak Sealer works on teak deck furniture, but I would not recommend it for a redwood deck, because of how expensive it is, and because I don't think it will hold up as well against constant foot traffic. I will continue to use it on the furniture. I use a deck stain finish and redo it every two years to maintain the protection for the wood. Because I have a termite challenge in Southern California, I treat the wood first with a termite protectorant on all surfaces. I hope my response helps.
2012-07-02RICHARD MORATH: I'm sure it would work, but I would probably just use Thompson's Water Seal from Lowe's. I have had good service from the Semco, but it hasn't been extraordinary.
2012-05-08TOD H. asked: I am looking for a glossy look but like the sealing characteristics of Semco better than Cetol. We have Cetol Original with a topcoat of Cetol gloss on the coaming and taffrail and Semco goldtone on the gunnel and transom deck edge. I was wondering what the effect would be to topcoat the Semco with Cetol's Gloss? Has anyone tried that? How is the adhesion and how does it look?
+Expand Answers
2012-05-08JOHN MILLARD: Tod,
That combination works well, Looks god and last long and is easy to touch up as regular Cetol.
Hope this helps. John
2012-05-08JIM HABERLY: Hi Tod,
I have a Hans Christian 43T and have been using Semco for years. I've not tried the Cetol clear over top but see no reason it wouldn't work. I always try a test panel first but that does take time. BTW - Have you seen the new Semco brown tone? Not many are selling it yet due to it being new (can get it straight from Semco). I tried a 100% brown and I tried 1:3 red:brown and I really liked the look of both. It looks much more like clean wet teak than the straight red tone does (a little to red for me). Just FYI - Cheers! Jim

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.
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.

Comments about Semco Teak Sealer:
Tried applying this product with a sponge brush but is very runny and is better applied with cotton rags/tee shirts. Very even coverage, absorbs well into the new teak chairs and tables I used this on. Has been through 6 weeks of heavy rains and is still working well and looks great. I highly recommend this product for all your teak sealing needs. I used the natural/clear product and love the results. Wish the product were less expensive, but you get what you paid for in this case.

Comments about Semco Teak Sealer:
Semco Teak Sealer is a fantastic product to seal and provide UV protection to boating teak surfaces and home furniture uses. We power washed then sealed all of our beach side teak this year and it provides such a beautiful natural tone, that some people thought we got new furniture. We waited five years which was too long. Will probably put a coat on each year from now on.

Comments about Semco Teak Sealer:
The frustrating expensive search for product to protect the teak deck and exterior trim work on my restored 42' Trojan has ended. Following extensive restoration, I didn't want to seal teak with epoxy or varnish (unnatural look and too hot to walk upon comfortably) but didn't want the "natural" grey look either. After sanding, applied three coats of Semco gold. While admittedly subjective, I LOVED the look. Lasted year easily, refreshed with one more coat. Excellent protection for deck. Speeds cleaning. Never looks "oily" or "greasy" - does not darken or bleach out. Works well on small trim pieces as well.
