Semeo WHO WE ARE…..

SEMCO was invented by my dad, Lawrence Serra, in 1976 when he could not find any product on the market to keep his teak looking good. While not setting out to be in this business he was quickly overwhelmed with requests for his new teak sealer. The rest is history. Without ever advertising these products and relying strictly on word of mouth, SEMCO has spread worldwide. It is now available through many great distributors and thousands of retail outlets.

SEMCO is still family-owned and operated;  SEMCO is used on pleasure boats, aboard cruise ships, in theme parks and is recommended by major teak furniture dealers. We proudly count several boats, canoe, and furniture manufacturers, as well as prominent hotels and shopping centres among our customers.

SEMCO can supply the material and on-site labour to use these products if needed. SEMCO is sold and recommended by top marine chains and garden furniture centres, web sellers and retailers.


By choosing teak you have selected the finest, most durable material available for outdoor furniture. SEMCO Teak Products will help protect your investment and enhance its natural beauty.

Teak with the beauty of its grain, rich colour, and timeless durability is treasured as the best-suited wood for use aboard boats, as decking on ships, and as the choice material for premiere outdoor furniture. However, these uses present the harshest of environments. Over time the elements will cause surface erosion, discolouration, mildew, greying, roughness and checking. The desire to prevent this ravage of the elements without becoming a “teak slave” gave rise to SEMCO Teak Care Products.

Because of teak’s natural resistance to rotting and insects, there are several options in caring for your furniture:

If you prefer to retain the natural, honey colour of the new wood, then seal your furniture with SEMCO Teak Care Products.

If you prefer a weathered grey look, then do nothing. Only under perfect circumstances will the teak weather to an even grey colour. Over time the wood will become rough in texture and the natural oils will be depleted causing cracks along the grain.

If the teak is weathered, stained or develops mildew it can always be restored using SEMCO Teak Cleaner.
