Yes, coating your sail well minimises the adhesion of mould to the sailcloth. To prevent mould as far as possible, you should never stow the sail away while wet.
Prevention is better than cure!
We recommend treating new sails straight away with an extra coating.
Naturally, sailcloth is already provided with a protective coating by the manufacturer. However, this protective coating disappears fairly quickly due to UV radiation. In many cases, this protective coating disappears after 1 season of sailing. You will notice that, because the sail takes longer to dry, becomes dirty and discoloured more quickly, and may already have mould.
Sail & Spinnaker Coating is very resistant to UV radiation. A sail treated with this protective coating remains clean and dry for longer and is more resistant to mould and algae, because it simply minimises adhesion to the sailcloth and the original, damaged coating.
