Sealing Teak, Why Seal?
If you wish to preserve the natural honey color of the new teak then seal your teak furniture with a product such as SEMCO Teak Sealer. It replaces the original teak oils that were used on the wood.

The teak is protected by its own natural oils that migrate to the surface of the wood over time. The elements oxidize this oil, turning the wood gray and promoting the growth of mildew. SEMCO Teak Sealer contains UV protection and a mildewcide to prevent this process. Products sold as teak oils are just linseed or tung oil mixed with solvents. Products such as varnish and polyurethane will peel and chip and are all but impossible to remove from intricate teak furniture.

When to Seal Teak?
The furniture should be allowed to weather for a couple of weeks or washed with a strong detergent prior to sealing. It is okay for the wood to get wet and be outdoors during this period. This process will remove the waxy feeling of new furniture which occurs when the natural oils have been polished or burnished by the sanding and milling process during manufactring. Failure to remove this mill glaze will result in a blotchy appearance and early failure of the sealer protection.

How do I Seal Teak?
Follow all directions on container closely for best finish. Apply sealer with a soft brush or a rag and wipe off the excess. It is not sticky, and can be applied at almost any temperature. The first coat will dry in under an hour. Apply a second coat in the same manner. But make sure to apply both coats in the same day. The furniture will be dry to the touch in a few hours and can be placed back in service the next day.
