Sika Sikaflex EBT+ Clear | Multipurpose Hybrid Adhesive, Sealant and Filler for Internal, External Doors and Windows - Grey - 300 ml

Product Information

Typical joint widths for joints between concrete elements for exterior applications Joint distance [m] Sika offers a wide range of high-performance and durable sealants, tapes, spray foams and elastic adhesives for the building envelope, for interior finishing and for infrastructure construction. Typical applications include the sealing of movement joints between facade elements to make buildings weatherproof, the bonding of wood floors to reduce noise or the sealing of joints in airport aprons.

Typical joint widths for joints between concrete elements for interior applications Joint distance [m] Other metals, such as copper, brass and titanium-zinc: clean and pre-treat using Sika® Aktivator-205 applied with a clean cloth. After a waiting time of > 15 minutes (< 6 hours). Apply Sika® Primer-3 N applied by brush. Before sealing, allow a waiting time of > 30 minutes (< 8 hours) PVC has to be cleaned and pre-treated using Sika® Primer-215 applied with a brush. Before sealing, allow a waiting time of > 30 minutes (< 8 hours). However, for optimum adhesion and critical, high performance applications, such as on multi-story buildings, highly stressed joints, extreme weather exposure or water immersion, the following priming and/or pre-treatment procedures shall be followed:Removal techniques such as wire brushing, grinding, sanding or other suitable mechanical tools can be used. PVC has to be cleaned and pre-treated using Sika® Primer-215 applied with a brush. Before sealing, allow a drying time of > 30 minutes (< 8 hours). All joints must be correctly designed and dimensioned in accordance with the relevant standards and codes of practice before their construction. The basis for calculation of the necessary joint widths are the type of structure, dimensions, technical values of the adjacent building materials, joint sealing material and the specific exposure of the building and the joints.

Example of typical joint widths for joints between concrete elements for exterior applications if the joint sealant is classified as ±35 % movement capability according to ASTM C 719, Calculation according to ASTM C 1472-10: Joint distance [m] Standard specification for elastic joint sealants, ASTM C920-11 Class 35, ASTM, Report, No 0314920-SIKA Note: Primers and activators are adhesion promoters and not an alternative to improve poor preparation / cleaning of the joint surface. Primers also improve the long term adhesion performance of the sealed joint.
