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. We also ship direct when customers have no outlet near them.

SEMCO is still family owned and operated; we are always available to answer our 800 phone number, or email,  for customer support.  SEMCO is used on pleasure boats, aboard cruise ships, in theme parks and is recommended by major teak furniture dealers. We proudly count several boat, canoe, and furniture manufacturers, as well as prominent hotels and shopping centers among our customers.

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