YACHTCARE Antifouling Primer is an elastic, one-component primer for underwater hull coating on GRP, metal and wood.The metal particles contained in the primer form a mesh of scales, which provides high-quality protection against penetrating moisture. It is also suitable as a barrier primer and adhesion promoter when changing antifouling. The antifouling primer serves as a base for all commercially available hard and self-polishing antifoulings, but not for antifoulings that contain metallic copper, such as PTFE thin-layer antifouling.Technical dataSubstrates: GRP, wood, steel, aluminum, existing commercially available antifoulingsPre-treatment: The substrate must be clean, dry and free of grease.
