Hydroflex construction sealant for connection joints SikaSeal-106 Construction is an elastic construction sealant for connection joints based on Sika’s innova-tive water-borne Hydroflex technology. Its good adhesion to most construction materials makes it especially suitable for a variety of interior and exterior sealing applications. - Very easy to apply, easy to clean
- Low stress on substrate
- Can be over-painted
- Phthalate free
- Water-borne
- Very low VOC emissions
- Good adhesion to porous construction materials
- Movement capability ±25 % (ISO 9047)
- Resistant to weathering
- Elastic over a wide range of temperatures
- 1-part ready to use

Service Temperature -40 °C min. / +70 °C max.
Joint Design The joint dimensions must be designed to suit the movement capability of the sealant. The joint width must be ≥ 5 mm and ≤ 15 mm. The joint depth must be ≥ 5 mm and ≤ 10 mm. A width to depth ratio between 2:1 to 1:1 must be maintained (min / max examples, see table below). | Joint width [mm] | Joint depth [mm] | | min. 5 | min. 5 | | max. 15 | max. 10 |
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. For larger joints contact Sika Technical Services for additional information.
