Altex PrimaShield Antifouling Sealer

PrimaShield Antifouling Sealer is a quick drying, general purpose, below waterline primer designed to provide both exceptional water barrier and tie coat properties to a large range of substrates prior to applying antifouling

PrimaShield Antifouling Sealer is used on the following substrates:

• Mild steel & Corten steel hulls & keels
• Timber hulls (sealed with Altex Epoxy TimberSealer)
• Aged exposed epoxy primers / undercoats
• Exposed fibreglass, gelcoat or GRP
• Aged antifoulants – suitable for use as a barrier/sealer coat between unknown or incompatible antifoulings.
