Previously coated boats application on top of old antifouling in good condition – easy switch to Silic One System
Hempel’s Conversion Primer is a two component epoxy primer for an easy conversion from antifouling to Silic One Fouling Release System, It can be applied on previously painted antifouling in good condition.
Surface preparation: identify the condition of antifouling you currently have on your boat. Use a metal scrapper to determine whether the aged antifouling adheres sufficiently. In case of bad adhesion, remove all loose/brittle layers. Abrade with wet abrasive paper. Rinse carefully with fresh water and allow the surface to dry.
Application: mix the two components of Hempel’s Conversion Primer thoroughly to an even consistency. Be aware that the product has a very low viscosity and any runs and sags should be brushed out immediately. Thinning is NOT recommended. Pot life at 20̊C: 8 hours. Minimum application temperature is 5̊C. In case the overcoating interval is exceeded, a new coat of Hempel’s Conversion Primer or Silic One Tiecoat must be applied accordingly.
