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 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

• When applying sealant into a previously silicone sealed joint, ensure
  all residue is removed from joint.
• SikaSeal®-190 N Silicone cannot be overpainted.
• Do not use on natural stone.
• Do not use on bituminous substrates, natural rubber or 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.
• Pre-test prior to use on prestressed polyacrylate and polycarbonate as
  it may cause environmental stress cracking (crazing).
• Pre-test in an inconspicuous area prior to use on porous material such
  as concrete to ensure the product does not stain the substrate.
• Do not use SikaSeal®-190 N Silicone 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, joints under
  water pressure or permanent water immersion.
• Do not use SikaSeal®-190 N Silicone in totally confined spaces as it
  requires atmospheric moisture to cure.
• 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.
