Backing Material:

Use closed cell polyethylene foam backer rod

Substrate Preparation: The substrate must be clean, dry, sound and homogeneous, free from oils, grease, dust and loose or friable particles, SIKAFLEX CONSTRUCTION PLUS adheres without primers and or activators, however, for optimum adhesion and critical, high performance applications, such as on multi-story buildings, highly stressed joints, extreme weather exposure or water immersion, the following priming and or pre-treatment procedures shall be followed:

Non-porous Substrates: Aluminium, anodised aluminium, stainless steel, galvanised steel, powder-coated metals or glazed tiles have to be cleaned and pre-treated using Sika Aktivator 205 wiped on with a clean towel before sealing allow a flash-off time, other metals such as copper, brass and titanium-zinc, also have to be cleaned and pre-treated using Sika Aktivator 205 wiped on with a clean towel, after the necessary flash-off time use a brush to apply Sika Primer 3N and allow a further flash-off time before sealing the joints, PVC has to be cleaned and pre-treated using Sika Primer 215 applied with a brush, before sealing allow a flash-off time.

Porous substrates: Concrete, aerated concrete and cement-based renders, mortars and bricks shall be primed using Sika Primer 3N applied with a brush, before sealing allow a flash-off time.
For more detailed advice and instructions please contact the local Sika Technical Services Department.

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.
