Semco Teak Wood Sealer Customer Questions and Answers

Question

I have just completed a new teak cockpit sole for my sailing boat. I was planning to let the teak turn grey naturally as I like the look and wanted to minimize maintenance. Are there any good reasons for me to consider using this product? I don't want to maintain the teak as if it were oiled.

Asked on 07/26/2011 by Undisclosed

Top Answer

I, like you, wanted to minimize maintenance on my teak deck and was getting tired of the old natural grey look. I tried Semco Teak Sealer several years ago and have used this product ever since. I apply two coats in the Spring and if needed, one coat in the fall. Absolutely no maintenance, applies easily and quickly, clean up drips with rubbing alcohol if some gets on fiberglass, wears very well and looks great. The hardest part of the whole project is deciding on which color to use. Suggestion: Try blending colors to achieve a special look.

Answer

I also don't like to "Oil" the teak. I wanted my teak to look natural but not weathered grey and also with minimum maintanence and Semco is the best I've used yet. I'm very pleased with it. Another brand looked as if it were painted on.

Answered on 07/26/2011 by JOHN BALTZEGAR

Answer

There is no need to seal teak if you are allowing it to age naturally.

Answered on 07/26/2011 by JIM TENBROECK

Answer

Both Semco and oil finishes need to be reapplied frequently to maintain their appearance. The advantage of Semco over oil in my experience is that the Semco does not seem to darken with age and collect dirt the way oil does. If the Semco is reapplied every month or two it needs only minimal prep work.

Answered on 07/26/2011 by WAYNE BEARDSLEY

Answer

I learned this from a British yacht captain friend of mine who maintains a 74 foot sailboat with a huge amount of teak inlaid decking. First, clean the deck with Oxyclean (yeah, the laundry stuff) using one scoop to one gallon of water. Apply it with a scrub brush, let it sit for a few minutes, scrub and rinse. If the teak is really dirty, do it again. Rinse and let dry for a day or so. When ready, apply Semco (I like the natural tint) with a foam brush. Do 2 coats, right after one another and wipe off the excess. Let it dry and you're done. The finish is beautiful and not slippery and the Oxyclean doesn't stain the fiberglass like teak cleaner does. The finish needs no maintenance, but if you get a little grey color mid-season, you simply have to apply more Semco....but don't clean it.....just apply another coat of Semco. It's a moldicide so it kills mold when the product is applied. It's great stuff and you'll love the way it looks.

Answered on 07/26/2011 by BOB HUETHER

Answer

I used the amber Semco Teak Sealer on my 42 Trojan to keep that "just sanded" fresh teak look on my decks. It's a very light coating, and very transparent. Semco offers some additional protection from soil and droppings (our marina has some serious spiders in the canopy issues). However, it does not allow the teak to grey - and if that is the look you're going for, I would not use it. However, if you want to keep the "new" teak look and some protection from the elements, this is an excellent product.

Answered on 07/27/2011 by MICHAEL BURNS

Answer

I have a 43' Hans Christian ketch trig that is COVERED with teak. I do all my decks, upper outer hull (3 plank decorative area), and the cap rail (toe rail) all the way around the boat with Semco. If you like I have not done the cockpit floor area as I have left that to go naturally grey. I like the "wet teak" look but do not want a tremendous amount of maintenance involved. After experimenting with difffernet product over the last 9 years on this boat I finally converged on Semco. Here are the things I like about it: 1. easy to apply, no mess, can re-use the foam brushes many times 2. no stripping, peeling, or blistering, can be removed with two part teak (or Behr deck) cleaners 3. not slippery when wet, traction is as good as bare teak (if not to many coats applied) 4. It seals around the screws and plugs to prevent water from entering the coring of the decks (some teak decks are only glued on). The water actually beads on and rolls off the teak decking. 5. NEVER starts to turn black or dirty as does many teak oils, dries hard 6. I mix the red and clear tones to produce the "honey" wet teak coloring that I want. This still looks a little redish in color if mixed to strong. 7. Can spot repair areas without stripping an entire region. It blends well enough and is easy to work with. If you are interested, I would be happy to send you photos of my boat. In any case, leaving the decks bare on my boat is more of an effort than the Semco. The decks never seem to get (or show I should say) dirt. I really had to work hard to keep them looking good without raising the wood grain before. When I bought the boat it was comvered with Sikkens Seatol. That was a disaster on the decks as it wore off constantly under my kids sand-covered feet and was VERY SLIPPERY when wet. Too many stubbed toes (etc). I recommend experimenting. In any case, I love and use a lot of Semco on my boat. If your would like to see photos you can email me at haberly2000@yahoo.com. Cheers! Jim

Answer

i have used semco for at least 10 years. we spend 5-6 months on a mooring at Two Harbors, Catalina Island. Lots of dirt, sand, bird droppings, grandchildren's oily foods, and fish blood and guts land on our decks. i have not had a permanent stain on any of the teak since using semco. everything comes off. i use a semco cleaner in the spring to get all the teak clean and then put 2 coats(right after each other) of a mixed blend in May and then touch up with clear in the fall. the deck is honey colored all year long. Our deck is not covered for 7 months a year and salt and/or fresh water is used daily to rinse off sand and dirt. no need for soap or a scrub brush!!!!

Answered on 09/20/2011 by BONNIE SIEMER

Answer

I sanded many years of varnish off my toe-rail, cleaned with an A/B cleaner and applied the sealer to a portion of the rail. So far ..a couple of months..the sealer is repelling water and is preventing the graying. Jury is out on longevity, but so far I am pleased with the results. If the marketing talk is accurate, I should be able to clean it every year and re-apply.

Answered on 07/31/2011 by BOB SCHOTMAN

Answer

I've got a 1972 Grand Banks 42 Classic that I purchased 2 years ago. I've been using the Semco for about 18 months & I really like the product. It is not an oil, but a sealer. Application is a breeze with a paint brush. However, it will maintain the honey color of fresh teak rather than allowing it to grey naturally. My 39 year old deck looks like it's brand new. I reapply when water fails to "bead up" on the deck. In South Florida, that's about every 2 months in the summer and 3-4 months in the winter as my boat is not covered. I've also stripped all the varnish off my teak rails and used the SEMCO to avoid trying to maintain the varnish. I mix two colors - natural & golden to achieve a more natural look as suggested by SEMCO. I can apply a coat to the entire deck in about 90 minutes, about 20 minutes for the dive platform.

Answer

Big help ! Thank you !

Answered on 06/04/2013 by Stephen S

Answer

Stephen: 1. For best possible results, unless teak is new, clean it using a good two part teak cleaner. I have had very good success with the Semco teak cleaning products. Be sure teak is completely dry before applying sealer. 2. I use the "natural" tone product and it keeps the teak looking new. I used the pigmented "Honeytone" product for a couple of years and it looked good, but I prefer the "natural." A friend uses the product with a slight red-orange tint and it looks good, also. 2a. In addition to the ease of use of this product, a change of color tone is only a good cleaning away. There is no painful stripping - just clean the teak with the two part cleaner and you can switch to a new color tone if you aren't completely happy with your first choice. 2b. Remember that you can reacoat the sealer every couple of months after your weekly fresh water and boat soap washdown. It is easy to maintain the finish as the product goes on easily and drys quickly. Comment: We have teak on the seats and floor of our cockpit. The sealer keeps the mildew out so white bathing suits don't walk away with black polkadots and it also maintains the non sikid properties of the teak. Other petrolium based products might preserve the teak, but they often make an ice rink out of the surface that needs to grip your topsiders.

Thank You Bill ! Appreciate your time !

Answered on 06/10/2013 by Stephen S

Answer

Yes, the teak should be cleaned. Teak will develop mold and turn a greyish color, so for best results either use a power washer or just soap and water depending on how clean you want to get it. I use the honey tone which is the closest to the natural color of teak then I use the semco teak sealer. I usually put 2 coats of the honey tone then 2 to 3 coats of the sealer. Hope this helps.

Does it work well on teak furniture?

Asked on 11/06/2012 by Undisclosed

Top Answer

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.

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....

Answered on 11/07/2012 by WILLIAM MACFIE

Answer

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.

Answered on 11/07/2012 by JAMES C WELLER

Answer

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.

Answered on 11/07/2012 by JOHN BALTZEGAR

Answer

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.

Answered on 05/26/2014 by RONALD DRAPER

Answer

Semco Teak Sealer is a wonderful product. We began using it on our boat teak in 1988. We simply washed the teak, let it dry and brushed on the Semco. On average, we did our teak twice each year but it was exposed to bright sunshine 365 days every year. If the teak started graying, we would scrub it with a mixture of baking soda, vinegar, and ammonia, rinse it off, let dry, and recoat. Semco does not stain clothing...doesn't rub off. We always got positive compliments on our teak. Enjoy your teak patio set.

Answered on 06/18/2013 by DAVE CHAMPLIN

Answer

If the teak has been cleaned with the two part cleaner (bare wood) then I'd start with at least two quarts. Poor a little into a cup at a time while applying so it does not evaporate while your putting it on. Having extra on hand also helps with touch up. I personally buy it by the gallon to save $. I've not had issues with the shelf life.

Answered on 06/18/2013 by JIM HABERLY

Answer

2 quarts minimum, if the furniture has not been treated for a long time, expect it will that much and possibly more. Get more than you think you will need; you will want to treat the wood once a year to keep up a good apperance. The sealer is easy to apply and clean up. Good product.

What is the life expectancy of this product and how many coats do I need?

Asked on 04/30/2013 by Undisclosed

Top Answer

Once I clean the deck with soap and water using a soft brush against the grain, and it dries thoroughly, I apply one heavy coat, wiping the product off of the caulk with a rag. Use gloves. Make sure you clean any splatter onto the gelcoat quickly. I wanted some color and additional pigment/UV protection, but the one color was too red for me. I have mixed the one color with the clear 50/50 for many years to get the color I want with the UV protection. I repeat this 2X per year. Best of luck to you.

Answer

I use Semco in a fresh water marine environment. The coverage of the product is good, but I think you will need a bit more than a quart. I would recommend buying by the gallon since it is less expensive and you will want to coat every year (or more often depending on your climate). The Honey Brown is a good look and I have used it, but I prefer the clear. It requires more coats of the clear for UV protection, but I prefer the natural look of the teak. I have used many products as a 22 year sailboat owner, and Semco Sealer seems to be the easiest and most effective. I love the fact that it is easily removed with teak cleaner. This allows you to get back to fresh teak with just teak cleaner and water - no sanding, no stripping. Good Luck.

What is the difference between clear and natural ? Does the natural contain a color additive ?

Asked on 07/05/2012 by Byron White

Top Answer

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.

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.

Answered on 07/11/2012 by PETER LEADEM

Answer

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.
