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.

Clean tools immediately after use with Sika Thinner C.
