Handy Tips


  • For a neater finish and easier clean up, you can tape both sides of the gap before applying the product.
  • Allow to skin (about 20 minutes) before painting with water-based paints.
  • Allow longer drying times (about 2 hours) when painting with flat or ceiling paints or in cooler conditions.
