Chemical Resistance

Resistant to water, seawater, diluted alkalis, cement grout and water dispersed detergents.
Not resistant to alcohols, organic acids, concentrated alkalis and concentrated acids, chlorinated, aromatic (hydro-carbons) fuel.

Joint Design

The joint dimensions must be designed to suit the movement capability of the sealant. The joint width must be ≥ 10 mm and ≤ 35 mm. A width to depth ratio of 1:0.5 for facade joints and a width to depth ratio of 1:0.8 for floor joints must be maintained (for exceptions, see table below).

Minimum joint width for perimeter joints around windows is 10 mm.

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. Joints ≤ 10 mm in width are for crack control and therefore non-movement joints.

For larger joints contact Sika Technical Services for additional information.
