Like Hempel’s Silic One, Seajet Bioclean Eco has a rubbery finish that fouling finds difficult to stick to. It is also a seven-coat system best used on bare gelcoat but can be applied on top of existing antifouling.
On bare gelcoat the process involves three coats of epoxy primer to provide a sound base, two coats of tie-coat, during which the colour element is introduced (black, white, navy-blue or red), then two coats of Biocleaneco – a transparent, paste-like substance.
When Raymariner was lifted, the majority of the test strip was admirably clean and shiny but there were some patches of fouling that appeared to have migrated across from the untreated dividing line separating this test patch from the neighbouring one rather than starting life on the black surface of Bioclean Eco itself.
Most of these dividing strips were painted with white International Trilux to avoid this happening but due to the longer application process of the silicone products we ran out of time on this one.
There was less slime than on the biocide products, and the wet microfibre towel test showed that it was easier to remove as well. Seajet expects this treatment to last for at least three years after which another tie coat and top coats should refresh it, although as this is a new product the recommended routine isn’t yet fully established.
