Joint Design

For movement joints, the width must be at least 6 mm and should not exceed 45 mm.
For non-movement joints such as connection joints in interior areas, the joint width
can be less than 6 mm.

The joint dimensions must be designed to suit the movement capability of the
sealant. In all cases joints must be at least 6 mm deep, or a have a width to depth
ratio of 1 : 0.5 (for exceptions, see table below).

Typical joint dimensions for joints between concrete elements:

• 12 metre long joint – 6mm width – 4mm Depth
• 6 metre long joint – 9mm width – 5mm Depth
• 4 metre long joint – 12mm width – 6mm Depth

For more information about joint design and calculations refer to the Sika document
Design guideline: Dimensioning of construction joints or contact Sika Technical
Services.

IMPORTANT CONSIDERATIONS

• Sikasil®-702 cannot be overpainted.
• When applying sealant into a previously silicone sealed joint, ensure
  all residue is removed from joint.
• Do not use on natural stone.
• Do not use on bituminous substrates, natural rubber or any building
  materials which might leach oils, plasticisers or solvents that could degrade the
  sealant.
• EPDM or other gaskets in direct contact must be tested for compatibility
  prior to application.
• Do not use on pre-stressed polyacrylate and polycarbonate as it may
  cause environmental stress cracking (crazing).
• Do not use on copper.
• Do not use Sikasil®-702 in areas which are exposed to strong oxidising
  acids (e.g. nitric acid) and bases.
• Do not use to seal joints in or around swimming pools for joints under
  water pressure or permanent water immersion.
• Do not use Sikasil®-702 in totally confined spaces as it requires
  atmospheric moisture to cure.
• Do not use for medical or pharmaceutical applications.
• Colour variations may occur due to the exposure in service to chemicals,
  high temperatures and/or UV radiation (especially with white colour shade). This
  effect is aesthetic and does not adversely influence the technical performance or
  durability of the product.
