Directions for Use

  • A joint with the correct dimensions is able to absorb movements between building materials
  • The joint depth should always be in the correct relationship of the joint width
  • A general rule is the ratio of joint depth to the width of the joint with a joint width up to 10mm is 1:1, with a minimum of 5mm in width and depth
  • For joints wider than 10mm, the depth is the width divided by 3 plus 6mm
