PRIMASHIELD SEALER 1L

PrimaShield Sealer is a quick drying, general purpose, below waterline primer for 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).

Advantages

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 on many different substrates to provide a stable, well-adhered surface ready for antifouling.

Uses

Exposed steel, wood, fibreglass, Gelcoat, GRP
Aged epoxies
Aged single pack primers
Multiple layers of antifouling
To convert incompatible antifouling to No.5, or Vivid or even Carboline.
To seal TBT type coatings where removal is extremely difficult or expensive
