Antifouling

Antifouling Paint Types
 

Self-polishing antifouls- the top layer of paint dissolves at a predictable rate revealing fresh layers of biocide in contact with the water (the boat needs to be used to wash away the depleted layer). Ideal for cruisers and sailing boats but will wear away too quickly if the boat goes more than 30 knots, is moored in silty conditions or is used very frequently.

CU-PRO - Contains a level of copper and biocide usually only found in commercial antifouling and is the strongest available to leisure users, it can give service intervals of up to three years.

Mare Nostrum - A good quality antifoul suitable for most craft, comes in 2.5 litre tins. Use NonStop for faster sail boats and cruisers  or if you find a normal antifouling dosn't last the season.

Aqualine Spray - Comes in a convenient spray. Suitable for out drives, flaps, shafts and outboard motors. Also useful for a small dinghy which is left in the water all of the time.

Hard antifouling paint- The binder is insoluble so the performance of the product decreases progressively throughout the season. It is resistant to abrasion and is suitable for speed boats and racing yachts. It may be polished to give a smooth surface.

Racing Antifouling - For speedboats and racing yachts that need to polish the hull. Also good for moorings that have a high silt level or that dry out.

 

The Jotun commercial antifouling (Yellow and red tins); SeaForce 30M, SeaForce 60M, SeaForce 90, SeaQuantum Classic and SeaQuantum Ultra are not available to leisure users and cannot be ordered online. To purchase Jotun commercial antifouling you will need to provide proof of commercial application via email and we will call you back.

TOP TIP: With self-polishing antifouling the more coats you apply the longer it lasts. It also has a shorter shelf life than other paints so don't leave it in the tin for next year - get it on the boat!

 

All our antifouling’s are suitable for GRP, wood, steel and ferro cement boats. Aluminium boats will require the white colours only. If there is antifouling already on the boat and you are not sure what it is it would be best to remove it with Strippit antifouling remover or give it a coat of Underwater Primer to seal it and provide a stable surface for the new coating. If you are using the same antifoul as a previous season and it is in a sound condition, you can just give the hull a wash and a wet sand then apply the new paint.

 

Antifouling primer

 

If this is the first time the boat has been antifouled or you have removed any previous coatings this would be a good time to look at the condition on of the hull and, if necessary, apply an epoxy primer such as SHIELD High Build Epoxy Primer or Jotun Penguard HB to protect a GRP or aluminium hull or something like SHIELD ST Epoxy Primer or Jotun Jotamastic 90 for steel or ferro cement hulls prior to applying an antifouling primer or tie coat.

 

Antifouling paints may not adhere well to bare GRP or epoxy primers used to protect GRP, metal or ferro cement hulls so you will need to apply a specialist primer (also known as a tie coat) such as SHIELD Underwater Primer in 2.5 litre tins or Jotun Vinyguard Silvergrey in 5 litre tins. These products will adhere well to the hull and provide a good surface for the new antifouling. You will also need to apply an antifouling primer to seal over an unknown antifouling (free from fouling and loose paint) if it is not being removed.
