Note: Primers are adhesion promoters they are neither a substitute for the correct cleaning of a surface nor do they improve the strength of the surface significantly.

Application Methods:

Sikaflex Construction+ is supplied ready to use over the top of the correct size Backer rod. After the necessary substrate preparation insert a suitable backing rod to the required depth and apply any primer if necessary.

Insert a foil pack into the sealant gun and extrude Sikaflex Construction + into the joint making sure that it comes into full contact with the sides of the joint and avoids any air entrapment. Sikaflex Construction Plus sealant must be firmly tooled against the joint sides to ensure adequate adhesion, it is recommended to use masking tape where exact joint lines or neat lines are required, remove the tape within the skin time.

Use a compatible tooling agent Sika Tooling Agent N to smooth the joint surfaces. Do not use tooling products containing solvents.

If Sikaflex Construction + is dry-tooled it shows a slightly structured, concrete-like surface. If it is wet tooled using a compatible tooling agent like Sika Tooling Agent N it shows a smooth surface.
