Directions of 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 till 10 mm is 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 6mm. Applied as an adhesive use it in a ‘ventilating’ way in vertical stripes with 30cm distance in between. The use of two sided adhesive tape, 3mm thick is recommended to support the adhesion during the first 24 hours and to make sure that the thickness of the adhesive is right.
