Technical Specifications: Joint Sizing and Application Methods
The seam depth/width ratio for seams up to 10 mm is 1:1. Minimum width and depth is 5 mm. For joints wider than 10 mm, the formula is simple: depth is width divided by 3 plus 6 mm.
Deeper joints require the use of a sealing gasket, while wider joints should be coated in triplicate, covering both sides followed by the bottom of the joint. It is also important to note that once the sealant has been applied, you must smooth the surface of the silicone with a rubber scraper and remove any excess.
