The product must be stored in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +5°C and +25°C. Always refer to packaging.

Refer to the current Safety Data Sheet for information on safe handling and storage.

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.

Note: The substrate temperature must be +3°C above dew point temperature and free from frost and ice.

The substrate must be clean, dry, sound and free from oils, grease, dust, cement laitance and loose or friable particles. Remove all dust, loose and friable material from all surfaces before application of activators,
primers or sealant. SikaSeal®-190 N Silicone adheres without primers and/or activators. For optimum adhesion, joint durability and critical, high performance applications the following priming and/or pre-treatment procedures must be followed, primers and activators are adhesion promoters and not an alternative to improve poor preparation/cleaning of the joint surface. The substrate should be of sufficient strength to withstand the stress induced by the sealant during movement. Use techniques such as wire brushing, grinding, grit blasting or other suitable mechanical methods to remove all weak substrate material. Repair all damaged joint edges with suitable Sika^® repair products.
