Additional Information

Mixing Process

  • Always use clean cold water, tools and containers.
  • Do not mix with residues of previously used compounds; use of dirty tools or containers may reduce working time and strength.
  • Always add Sheetrock® EasyJoint™ 20  to water (5kg of powder to 2.5kg of water).
  • Mix only enough Sheetrock® EasyJoint™ 20  to meet needs.
  • Mix by hand or with a power mixer (max of 400rpm) until a workable paste has been achieved.
  • Caution: Do not overmix; overmixing can introduce air bubbles, which can create surface imperfections and reduces working time.
  • Once setting has commenced, the material cannot be remixed and must be discarded.

Application Process

  • Surfaces must be clean and free from dust.
  • The use of paper tape is recommended such as Knauf Paper Joint Tape.
  • Ensure there is sufficient amount of compound under the paper tape to provide adhesion.
