To know before applying

  • All surfaces should be clean, dry, free from grease, oil or dust and any contaminants that could harm bonding.
  • Remove old sealant residue completely before applying new sealant .We recommend cleaning concrete with a metal brush.
  • If necessary, rub down metal surfaces beforehand. After rubbing down, the surface should be re-cleaned.Allow the substrate to dry after degreasing.
  • For a cleaner job, protect the edges of the joint with self-adhesive masking tape.
  • If required place a backer rod inside the gap to be filled for correcting the depth.
