Semco Teak Sealer

SEMCO Teak Sealer protects teak while keeping a natural, low-build appearance. A two-coat initial application followed by occasional cleaning and a single maintenance coat when needed helps preserve teak on boats and outdoor furniture without the constant upkeep of traditional teak oils.

Choose your colour

• Natural: golden-tan, slightly weathered teak appearance; popular for boats.
• Honeytone: rich honey colour similar to new teak; popular for furniture.
• Gold Tone (SEMCO Goldtone): reddish-brown freshly sanded teak appearance.
• Brown (SEMCO Classic Brown): darker brown, similar to wet teak.
• Cleartone: no pigment and an oiled-wood appearance. Less weather-resistant than the pigmented shades, so more frequent recoating may be needed.

The gallery includes five individual manufacturer colour examples. Any older comparison chart is illustrative only; order from the five colour options listed above. Manufacturer samples are a guide only: wood grain, preparation, existing finish, lighting and screen settings affect the final colour. Test on your own teak first. Cleartone sealer is not SEMCO Clear Coat, the separate patina/stain-resistance product.

Application and maintenance

Start with completely dry, properly prepared teak. For grey or stained wood, use SEMCO Two Part Teak Cleaner first. New teak must lose its waxy/burnished surface before sealing.

• Mix thoroughly and keep the contents mixed during use.
• Apply two initial coats on the same day; the second can follow after completing the first. Wipe excess from the wood after each coat.
• SEMCO quotes touch-dry in about one hour and service the next day; cool or damp conditions slow drying. Follow the label for your conditions.
• Approximate coverage per gallon: first coat 200 sq ft; second coat 400 sq ft. These are individual coat yields, not combined two-coat coverage.
• Clean with mild soap and water. Add a single fresh maintenance coat seasonally only when needed. Water beading indicates the sealer is still working; excessive coats can mask the grain.

Read the product label and SDS for safe handling, ventilation and disposal. Select the existing colour and size options above.
