The joint width must be designed to suit the joint movement required and the movement capability of the sealant. The joint width shall be ≥ 10 mm and ≤ 50 mm. The joint depth shall be ≤ 10 mm. A width to depth ratio of 2:1 must be maintained. All joints must be correctly designed and dimensioned in accordance with the relevant standards, before their construction. The basis for calculation of the necessary joint widths are the type of structure and its dimensions, the technical values of the adjacent building materials and the joint sealing material, as well as the specific exposure of the building and the joints.
Note: Test certificates should be referred to while designing a firerated joint

Use polyethylene foam backing rods

Note: The Substrate temperature must be +3°C above dew point temperature and free from frost and ice. 

The substrate must be sound, clean, dry and free of all contaminants such as dirt, oil, grease, cement laitance, old sealants and poorly bonded coatings which could affect adhesion of the primer and sealant. The substrate should be of sufficient strength to withstand with the stress induced by the sealant during movement. Use techniques such as wire brushing, grinding, grit blasting or other suitable mechanical methods to remove all weak substrate material. Repair all damaged joint edges with suitable Sika® repair products. Remove all dust, loose and friable material from all surfaces before application.

Clean all tools and application equipment immediately after use with water. Once cured, residual material can only be re-moved mechanically.
