All indsor connection joints (except toilet for bathroom
DIRECTIONS OF USE
A joint with the correct dimensions is able to alisorb
movernments between building materials. The joint dopth should always be in the corect relationship of the joint wea A general rule the ratio of joint depth to the width of of the Joint with a joint width up to 10 mm 1/1 with a minimum of 5 mm in width and depth. For joints wider than 10 mm, the depth is the width divided by 3 plus 6 mm.
