Product Details

Semco Teak Wood 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.

Choose from three popular shades: Cleartone, Natural, and Goldtone.

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.

Great Product
By EHT from Louisiana

Verified Purchase

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.

Bottom Line Yes, I would recommend to a friend

This worked well for me and my family.
By Sharon from Aiken, SC

Verified Purchase

I used this on my outside teak deck after thoroughly cleaning it and hand sanding rough areas. I sealed it with this and it left me with a beautiful color on the deck in combination with another pigmented sealant I also used. I combined it outside for a beautiful finish which my family members said made the deck looked like it did when I first got it installed.

Bottom Line Yes, I would recommend to a friend
