Product Details

Semco Teak Wood Sealer waterproofs and protects teak furniture and marine wood surfaces. 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 of this wood can cause blistering or peeling. Most common teak protectants are solvent and linseed oil based, and oxidize over time. The oxidation 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 for a clear finish, Natural for golden tan glow, and Goldtone for reddish-brown luster. Available in Quart and Gallon sizes.

Info & Guides

Technical Information

  • 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.
  • Cleartone contains no pigment, looks like oil, and is not as weather resistant as the other shades.
  • Natural imparts a golden-tan glow to the wood that resembles slightly weathered teak.
  • Goldtone produces the reddish-brown luster of teak that has been freshly sanded.

I used 2 coats on the rockers as they were older. Just one coat on the adirondack chairs as they were new. Will follow up with another coat later. The Semco sealer is great!

Older teak

2 years ago
Just finished resurfacing older teak deck. Very carefully skimmed off proud caulking with sharp 3/4"" chisel. I am a woodworker and am experienced with chisels. Way faster than sanding, quieter and very precise to protect surrounding delicate areas. Random orbital sand 80 still necessary but half the time. I previously washed and moderately scrubbed with cleaner and brightener. My aim was to knock the grain down mostly but to get absolutely flat would have removed way too much material. Two coats natural sealer went on very quickly and easily. Coat 1 absorbed pretty dramatically coat 2 somewhat less so. Foam brush didn't carry sufficient material and used 2"" nylon brush which allowed me to work into the surface better and faster. Results are decent and am quite pleased with apparently harder, easily cleaned surface and food is not leaving oil spots as much. There is little doubt maintenance coats will be necessary over time. Please be aware this material is very thin and can splatter if windy. Also note the natural has very little pigment and do not expect it to hide all of the grey oxidation in the deep grain of older decks which is very difficult to completely eliminate. Perhaps the darker tone would but I was afraid of it looking more splotchy. I like the results very much and like the drier harder surface more than oil for this older deck. In cases where I could have sanded more aggressively I probably would have used the darker colors but I did not have that option in this case as previous owners had already done a number and removed a fair amount of material. Bottom line, good stuff that I plan to stick with regularly…….spring, mid summer, maybe fall if I am still interested. Might go darker subsequent coats.

Great Product

I really like this product. I sanded down my teak deck, cleaned it up and applied two coats of the natural tone with a foam brush followed by a rag. A little bit of this goes a long way, you can apply the second coat immediately after the first and it turns a very pretty golden brown.

Q: Using the teak sealer on a sail boats teak do I have to put anything else on to make it last longer

8 months ago
1 Answer

A: No, you only use the sealer. Other products are not compatible. How long it lasts depends on your climate and how much UV exposure it gets. Regular maintenance is required so it's a good idea to clean the teak and recoat it before it starts to show signs of wear

Q: What is the difference between clear and natural sealer for teak outdoor furniture? Considering using Semco product.

5 years ago
2 Answers

A: I would go further and say that the clear color really doesn't hold up. Semco even says so. Why use a sealer that doesn't seal. I don't agree that goldtone looks like fresh-sanded teak - it is orange tinted more like wet teak, maybe even a little more orange than that

Q: I'm trying to decide on which tone for my outdoor teak furniture. It sounds from reading the comments it is between natural and gold tone. I like reddish brown, but not orange. Do you believe natural should be my choice.

2 years ago
1 Answer

A: I got the Gold Tone the first time I bought it for the deck on my boat. It was VERY orange in color. I now use the natural. In the can it looks orange/brown, but after you put it on and wipe it off, it's muted down to a brown. Use a two/three part teak cleaner first or you will get lots of spots of color. Also mask off any areas that might get spatter as it will stain concrete, painted surfaces, etc. Good luck! Cheers!,

Q: I am absolutely going to use Semco, it checks all of the boxes for me. I've done a fair amount of research and can't quite find the answer I'm looking for. I have teak that has been abused for a long time. I washed my teak and it is extremely grainy and not smooth at all- lots of ridges. Should I sand it down before I apply semco? Do I have to clean it after or just get all of debris off then seal? Thank you!

A: Chris. I have a 30 year old sailboat with teak decks that I have had for 20 years. I have used boat soap and water for 10 years and had decks where there were ridges of heart wood and valleys of sap wood. No coating. I did a lot of investigating also (I am a chemical engineer with 40 years experience) This is a complex problem with no prefect answer. I decided to first clean the deck with a mixture of soap, oxalic acid 7 oz. powder/gal. water. Leave it on for 10-15 min. then rinse with water saturated with baking soda to neutralize the acid absorbed into the teak (let it soak for about 20 min- - Make sure all bubbling has stopped for at lease 10 min.) then rinse it well with plain water. You now have a very clean deck and when dry you can sand it gently to get rid of about 80% of the ridges. I would not sand it completely flat. I then put on the Semco. I would only use the clear. You will be faced with reapplying a coat every 4-6 Months. Buy your oxalic acid and bakeing soda in bulk , on line, not from a store that is premixed! Hope this helps. Read up on how to manage oxalic acid first. Steve
