APPLICATION INSTRUCTIONS

  • All surfaces to be sealed must be clean and dry and free from friable material.
  • Fill deep gaps and voids with expanding foam, then trim back level with bath/shower tray before applying Sealant.
  • When applying to plastic & acrylic baths, fill bath half full with water whilst sealing and during cure. This provides the mid-point of any movement that will be encountered.
  • Always tool sealant down to ensure a proper bond is achieved.
  • Tool within 15 minutes of applying.
