  • Many, many thanks for all your advice and encouragement, I fully endorse the product, it was easy to use and even on a piece this size I had to work on.

    Ian / Dorset

  • Having been professionally advised that my teak was irreparable. I wasn't prepared to accept a costly replacement, and as an engineer myself decided to try Semco's Premium Products. I'm very happy to see the results that using their products provided. 😁😁

    Stephan / Germany

  • Just a message to say how impressed I am. Ordered just before midday yesterday online, arrived at about 10.30 this morning, 2 coats applied with the sponge applicator included this afternoon. Service fantastic, product so easy to use, results excellent. Thank you.
