Substrate Preparation / Priming

Clean and dry, homogeneous, free from oils and grease, dust and loose or friable particles. Cement laitance must be removed.

It has a generally strong adhesive property to most clean, sound substrates.

For optimum adhesion and critical, high performance applications such as multi story building work, for high stress bonding joints or in case of extreme weather exposure substrate primers and cleaners must be used. If in doubt apply product in test area first.

Non porous substrates: Glazed tiles, powder coated metals, aluminium, anodised aluminium, stainless steel and galvanised steel have to be cleaned with a fine abrasive pad and Sika Aktivator-205 by using a clean towel or cloth. Before sealing allow a flash off time of at least 15 min.

All other metal surfaces not mentioned above have to be cleaned with a fine abrasive pad and Sika Aktivator-205 by using a clean towel or cloth. After a flash off time of at least 15 minutes, apply Sika Primer 3N by using a brush. Before sealing allow a flash off time of at least 30 minutes (max. 8 hours).

For PVC use Sika Primer-215. Before sealing allow a flash off time of at least 30 minutes (max. 8 hours).

Porous substrates: Concrete, aerated concrete and cementitious renders, mortars, brick, etc. have to be primed with Sika Primer-3N by using a brush.

Before sealing allow a flash off time of at least 30 minutes (max. 8 hours).

Important note: Primers are only adhesion promoters. They neither substitute for the correct cleaning of the surface nor improve their strength significantly.

Primers improve long term performance of a sealed joint. For further information please refer to the Sika Primer table.

Substrate Temperature

+5°C min. / +40°C max.

Ambient Temperature

+5°C min. / +40°C max.

Dew Point

Substrate temperature must be 3°C above dew point.

Application Method/ Tools

Supplied ready to use.

After suitable joint and substrate preparation, insert Backing Rod to required depth and apply primer if necessary. Insert cartridge into sealant gun and firmly extrude in to joint making sure that it is full contact with the side of the joint. Fill the joint, avoiding air entrapment. It must be tooled firmly against joint sides to ensure good adhesion.

Masking tape must be used where sharp exact joint lines or exceptionally neat lines are required. Remove the tape whilst the sealant is still soft. Sleek joint with smoothing liquid for a perfect sealant surface.

Tool Cleaning

Clean all tools and application equipment with Sika Remover-208 / Thinner C immediately after use. Hardened (cured) material can only be removed mechanically
