UHP water jetting is the best option to remove a silicone coating from a ship's hull to replace it with an epoxy mastic. We can vary the flow rate and pressure as required.

Look at pressurized water, from pressure washing up to Ultra-High Pressure Waterjetting (UHP WJ). You can vary the flow rate, the pressure, the stand-off distance, and the lateral movement to remove the silicone. And you can collect the material with a vacuum. If you clean to bare metal, the profile will be what is under the silicone.

If you are using sponge abrasive for blasting, you should not recycle it, because you obviously are left with residues of silicone in the polyurethane foam. If using recycled abrasive, you are pushing silicone into the substrate.

I would suggest using the AB-4 method for surface preparation. This will allow you to achieve an SSPC-SP 10 and any desired profile.
