Antifouling
Over the years I have sold and had feedback from my customers for a number of different antifoulings. Many times it happens that one boat owner may have had a good experience with a certain antifouling brand while another not! Here is a small summary of what I have heard and know.
Greek antifouling generally used to be quite strong, but this has been changing lately. (for the worse)
Seajet antifouling says on the tin you can get two seasons out of two ciats and this has been tested by a customer of mine. It is apparently true!
A lot of people use "shipping" strength a/f which only comes in 20L containers. This may often be stronger and ,importantly for some, cheper but it is ,strictly speaking illegal. I hear that the authorities abroad are now spot checking boats in boatyards for use of illegal antifoulings, but this will obviously take some time to arrive here...
|nternational make a number of antifoulings which are not suited to our ,very warm and full of fouling potential, waters. Paints like Cruiser Uno or Unipro professional are not really suited for heavy fouling areas. Also most if not all of the natifouling sold in Holland is quite weak. That is because legislation there is very strict.
In my opinion a strongly contributing factor to the perforance of an antifoul is who and how actually put it on the boat. Antifoulings are not resin based they are pigment based paints. In many cases it is the pigment itself ,usually some metallic oxide which is also the active ingredient. For this reason they are very much affected by the amount of thinner.diluant used. It is agood idea to avoid using any all but if needed you should not exceed 5% at most.
As it is getting a little late, I shall break off here and wait for some feedback . More tomorrow !!!
I look forward to seeing your comments!
