HOW TO APPLY FOULFREE

For better adhesion of Foulfree Transducer Coating on plastic fairing (polyethylene, polypropylene, nylon, etc.), you may need to use a piece of 40 grit sandpaper—NOT included. First, abrade the fairing block with 40 grit sandpaper to achieve a roughened surface, and then remove any residue from sanding. DO NOT sand the transducer housing or face as it will damage the transducer, voiding the manufacturer’s warranty.

The Foulfree kit comes with tools included in the box, however, you will need some additional materials for the application process:

• Disposable gloves
• Eye protection
• Mask
• Clean, dry rag
• Tape
• Fairing blocks only - 40 grit sandpaper

Remove fouling and/or any previous coatings from the transducer housing and face with the abrasive pad provided.
In case of heavy fouling, scrape transducer face with a metal putty knife without gouging the surface. Drag the putty knife across the transducer face at a perpendicular angle and follow with a wet sanding block. Never use a power sander or pressure washer on the face of the transducer.
Take care not to scratch or damage the transducer face.

Firstly, lightly scuff/abrade plastic housing and face of the transducer. Do not scour or deeply scratch the face of the transducer.

After abrading the transducer, tape off any areas you do not wish to coat with the Foulfree Transducer Coating.

Clean the surface to be coated with our specialised cleaning wipe. XDclean is transducer safe and ensures a contaminant-free surface for the Foulfree coating.

Immediately remove any residue with a clean, dry rag. Ensure the surface is 100% clean and dry before proceeding.

APPLICATION TIP

• Use a clean and dry rag to remove any residue
• Ensure the surface is 100% clean and dry before proceeding

Apply XDprime generously using the provided wipe. Once applied, allow 10 minutes to dry.

XDprime will look wet when first applied and will leave a white cast when dry. The surface is now ready for coating with Foulfree.

APPLICATION TIP

• Allow 10 minutes to dry before applying Foulfree
• XDprime will turn white once dry

We have included a small, high-quality brush to provide the best result.
Pierce the seal of the tube using the lid. Squeeze a small amount of the Foulfree coating directly onto the brush.

Apply a thin layer of the coating onto the transducer. The ideal thickness is between 50 and 100 microns. Make sure there are no heavy runs or sags. You will have 5 to 10 minutes to touch these up.

APPLICATION TIP

• Use the provided brush to apply Foulfree
• Make sure there are no heavy runs or sags

Foulfree requires a minimum of 8 hours to dry before launching. In colder conditions, 40–60°F / 5-13°C, wait at least 24 hours before launching. Foulfree can sit out of water for extended periods of time in warm or cold climates with no adverse effects.
