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).

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.

Application steps

SUBSTRATE PREPARATION

The substrate must be sound, clean, dry and free of all contaminants such as dirt, oil, grease, cement laitance, old sealants and poorly bonded paint coatings which could affect adhesion of the sealant. The substrate must be of sufficient strength to resist the stresses induced by the sealant during movement.

SikaSeal®-106 Construction adheres without primers and/or activators.


Concrete, aerated concrete and cement based renders, mortars and bricks surfaces can be primed if required using SikaSeal®-106 Construction dissolved in water (ratio 1:1–1:5) and applied by brush.

Iron and steel

Must be protected with an anti-corrosion primer. Contact Sika Technical Services for additional information.

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use. Hardened material can only be removed mechanically. For cleaning skin, use Sika® Wonder Wipes.
