Good to know

  • Ensure surfaces are clean, dry and free from dust, grease and contaminants before application
  • Wipe PVCu surfaces with PVC Solvent Cleaner, glass with Glass Cleaner, and painted surfaces with white spirit for improved adhesion
  • Priming is generally not required, but always test a small area first, use Silicone Primer NP2 for non-porous surfaces or Silicone Primer P1 for porous surfaces if needed
  • Joint width should be between 6mm and 50mm; depth should not exceed 50% of the joint width
  • Skin time is 5–25 minutes, tool the sealant promptly after application
