Do I need a primer before applying F2?Updated 16 days ago

That depends on the type of substrate and the preparation.

When the old coating (antifouling) is not removed

In this case, it is crucial to seal the old layer and create a stable adhesive base. Use F2 Primer as a Conversion Primer for this purpose.

When the substrate is completely rebuilt

In this case, you can omit the F2 Primer and use a primer that is suitable for the hull.

• GRP Hulls: We recommend a classic 2K epoxy primer which offers robust additional protection against osmosis.

• Aluminum/Steel Hulls: A suitable corrosion protection primer is absolutely necessary to prevent corrosion and electrolysis.

• Wood Hulls: Use a special wood primer that protects the material and optimizes adhesion.

Important Note on Solvents

No matter which primer you use, always pay attention to the solvent content. If the primer contains solvents, it must air out for several days and then be lightly sanded again before F2 Adhesive Coat is applied. You can skip this step with a solvent-free primer.
