Fouling on your boat not only makes it look unsightly, it can also foul propellors and outdrives, block engine water inlets and outlets, slow down the boat speed, increase fuel costs and ultimately damage the substrate.
|
|
The quantity and composition of the fouling community varies widely from site to site and is affected by temperature, salinity and water quality. The different levels and types of fouling on vessels which are moored in, what would appear to be, the same environment, can be quite dramatic, as fouling conditions are affected by sunlight and shade, temperature and flow of water, pollution levels and freshwater inflows. Fouling grows faster in sunlight which means it is first seen on the waterline and the rudder; dirt and pollution in the water surface can close the active material in the antifouling, so we recommend you apply extra layers on the rudder and the waterline to make these areas resistant to frequent washing. | |

|
The right choice
Choosing the correct antifouling or bottom coat is important. You should consider your boat type, sailing pattern & speed, geographic location and the characteristics of the mooring, any existing coating, as well as environmental and legislative issues in the area where you apply the product and then sail.
Types of antifouling
Antifoulings tend to fall into three different categories which are Erodible (sometimes called Self Polishing), Hard and Traditional/Soft.
|
|
Erodible (self polishing) antifoulings have a resin system packed with active ingredients to repel/discourage fouling growth, once immersed the resin breaks down in a controlled manner, continually exposing a fresh layer of biocide to the water. This provides consistently good performance throughout the sailing season and reduces the build up of old antifouling on the hull.
Traditional/Soft antifoulings have a simple resin formulation dispersing the active ingredients with the binder, offering good protection at an economical price. Traditional antifoulings should not be sanded.
| Hard antifoulings have a resin system with a high proportion of insoluble resin making them hard, stopping the coating erode. The resin is packed with active ingredients, each particle being in direct contact with its neighbour, as a particle is dissolved by the water the particle immediately behind it is exposed. Because of their hard nature and durability, they are ideal for high speed power boats, vessels which are mud berthed and racing yachts where a smooth finish can be achieved by burnishing the antifouling with wet abrasive paper before the boat is launched. |
|
Bottom Coats. Hempel have developed effective bottom coats to suit areas of the World were the use of poisons are restricted. These coatings have carefully engineered resin matrices that dissolve in a controlled manner to keep fouling to a minimum without the use of harmful poisons.
| Overcoating advice |

Overcoating information
On the whole most antifoulings are compatible and can easily be overcoated, however, some basic rules should be applied:
The condition of the surface to be painted must be good - ie free from contaminates and in a sound condition.
A hard/non-polishing antifouling will leave an exhausted layer of resin at the end of the season. Before applying a new coat, it should be wet abraded to maximise the performance of the antifouling.
A Teflon antifouling CAN be overcoated assuming it is in good condition and has been washed - DO NOT abrade before applying new antifouling.
A traditional/soft antifouling should be sealed with Underwater Primer before applying an erodible or hard antifouling on top of it.
| HEMPEL HINTS FOR ANTIFOULING |
- If you are changing your antifouling, check application instructions of new product onto existing product. If in doubt, apply a tiecoat of Underwater Primer.
- Keep the antifouling paint indoors before painting your boat as antifouling is easier to apply at "room" temperature.
- Always give antifoulings a good stir before applying as they contain heavy pigments which can settle.
- Apply an extra coat of antifouling along the waterline and the leading edges where more aggressive water flow takes place.
- It is not advisable to thin antifoulings, however, in particularly cold conditions thinning the antifouling by up to 10% will help with application.
- Never dry sand old antifouling as the dust is toxic.

Quick drying, high opacity primer and undercoat providing excellent durability and surface stability in preparation for overcoating with single pack systems. Suitable as an above water primer for all substrates (especially steel) and as an undercoat for Brilliant Enamel. |
 |
Underwater Primer - 2.5l & 750ml
A fast drying, underwater primer with excellent waterproofing properties. For use as part of a single pack system all areas and substrates below the waterline - including keels. Also use as a tiecoat before antifouling, either directly onto the hull or onto a primed surface and between an existing antifouling and a new antifouling. |
|
Light Primer - 2.5l & 750ml & 375ml
For use on glassfibre, wood, steel and aluminium, a two pack high performance epoxy priming and undercoating system. This product has outstanding corrosion, impact and water resistance qualities both above and below the waterline. Can be used for osmosis protection when application takes place at low temperatures. An excellent protective coating between the substrate and Poly Best topcoat, ensuring longevity of the system. |
 |
Sealer 599 - 750ml
A two component epoxy sealer with low viscosity giving it exceptional penetrating properties, making it ideal as a sealer coat onto bare wood and other porous substrates, such as ferrocement. Also good on suitably prepared glassfibre and polyethylene. For use above and below the waterline. |
|
High Protect - 2.5l & 750ml
HighProtect is two component solvent free high build epoxy, especially developed for osmosis treatments. Can be applied at, and will dry to, a very high film thickness. Can be used as a substitute for Light Primer where solvent emissions are a consideration. |
