Excellent

Sikasil® N may be applied in joints with a minimum joint size of 5mm wide x 8mm deep and a maximum joint size of 20mm wide and 10mm deep.

Application temperature: +5°C to +40°C

• Joint surfaces must be clean, dry and free from frost.
• Remove all dirt, laitance, loose materials, grease and foreign matter.
• Oily surfaces should be degreased with Sika Thinner C.
• In all joints a bond breaker must be used to prevent sealant contact with the back of the joint, and hence allow optimum performance. In shallow joints self-adhesive polyethylene tape can be used. Deep joints should incorporate a backing rod such as Sika PEF Rod to support the sealant while also acting as a bond breaker.
• For a neat finish mask the areas adjacent to the joint.

Priming

• On all surfaces good sealant adhesion requires the use of a primer.
• For concrete, mortar, block, brick, timber and other porous surfaces use Sika® Primer-3 N.
• For glass, PVC, metals and other non-porous surfaces clean using Sika® Aktivator-205.  

• For plastics and other non-porous surfaces that are difficult to bond to gently rub down substrate in single pass with abrasive pad and clean with Sika® Aktivator-205.
• Allow primers to dry for a minimum of 30 minutes and a maximum of 8 hours before applying sealant.
