PrimaShield Sealer is a quick drying, general purpose, below waterline primer fro steel and wooden surfaces. PrimaShield Sealer has been formulated for use on metal keels and hulls prior to antifouling. It is however also suitable for use as a barrier/sealer coat between unknown or incompatible antifoulings.

PrimaShield Sealer also helps prevent leaching of TBT from an underlying antifouling coating provided it is applied at a minimum dry film thickness of 80 microns (minimum 2 coats by roller).


  • Single pack direct to steel primer
  • Excellent corrosion protection
  • May be used to seal old antifouling coatings
  • Fast dry time
  • Excellent application properties
  • Excellent water immersion resistance
  • Reinforced with aluminium flake
  • Excellent flexibility for wooden hulls

PrimaShield Sealer can be used over many different substrates to provide a stable, well adhered surface ready for antifouling.

  • Exposed steel, wood, fibreglass, Gelcoat, GRP
  • Aged epoxies
  • Aged single pack primers
  • Multiple layers of antifouling
