FS Primer 2K is a bonding agent for polysulfide joint sealants.
The substrate can be dry or pore saturated, however there may be no water film visible on the surface. The substrate must be free of silicones, loose particles, oil, and grease. For cleaning substrates, we recommend the use of dirt and grease dissolving water or solvent based cleaning agents. If necessary hot steam clean, grind lightly, or roughen by sandblasting.
