Silic One is a new generation biocide-free antifouling system that offers boaters peace of mind and lasting protection.

This FAQ article compiles the most common questions about the system's use, coating renewal, different substrates, and the Infinity update. Whether you are a first-time user or an experienced maintainer, you will find clear answers here.

Structure and Use

What is the structure of the Silic One system?

General

What is Hempel Silic One?

Silic One is a biocide-free antifouling paint based on silicone and hydrogel. It forms a slippery surface to which organisms do not adhere. When moving, fouling easily detaches from the boat's bottom.

How does the Silic One system work?

The system applies a hydrogel surface to the boat's bottom, resembling water. This prevents fouling from attaching and allows for easy cleaning without harmful substances.

When can the boat be launched?

At the earliest 24–36 hours after painting, at the latest within 1 month.

How often should Silic One be renewed?

The topcoat is recommended to be renewed every other year. In the interim season, Infinity gel can be used, eliminating the need for repainting.

Can the system be used on propellers?

Yes, but prime with Light Primer (20% + 5% thinning) before applying Tiecoat and Silic One layers.

Maintenance and Infinity Coating

How to inspect and maintain Silic One coating

The topcoat lasts for several seasons. Inspect annually and touch up or use Infinity gel to extend protection as needed.

How does Infinity relate to Silic One?

Infinity is a colorless, water-based gel applied over an intact Silic One surface after the season. It requires no sanding or masking and allows for an additional season without repainting.

Touch-up and Repair

How do I repair a Silic One surface?

  1. Wash the surface
  2. Lightly sand the damaged area
  3. Apply Tiecoat
  4. Add 2 coats of Silic One paint
  5. Allow to dry according to instructions

When should the system be completely renewed?

If the coating is extensively damaged or old, remove Silic One completely and start over with Light Primer.

Old Antifouling and Silic One

Can Silic One be applied over old antifouling?

Yes, if the surface is in good condition: use Conversion Primer before Silic One. If the surface is poor or more than 10 years old: remove old antifouling with Stripper and apply Light Primer (4–5 coats).

Can I paint traditional antifouling over Silic One?

No. Silic One must be completely removed before using any other antifouling.

Can Silic One be removed?

Yes, with Hempel’s Silicone Remover.

Compatibility, Cleaning, and Availability

Can a high-pressure washer be used?

Yes. Recommendation: max. 200 bar, spray angle 20–30°. Avoid brushing with hard brushes.

What hull materials is Silic One suitable for?

Fiberglass, aluminum, steel, plywood – provided Light Primer is used on metal surfaces.

In what colors is Silic One available?

Black, blue, and red.
