Masking tape can be used when neater joints are required. Remove the tape within the recommended skin time.

    Surface Preparation

    Sikaflex PRO-3 SL has strong adhesion without primers/activators to most dry, clean and sound substrates. For optimum adhesion in high-performance applications such as multi-story building work, high-stress areas, extreme weather conditions or continued water immersion, the following procedure shall be followed:

    Non-porous substrates:

    Aluminium, anodised aluminium, stainless steel, galvanised steel, powder-coated metals & glazed tiles have to be thoroughly cleaned and treated with Sika Aktivator-205. Before sealing, allow a flash-off time of at least 15 minutes & no longer than 6 hours.

    Metals like brass, copper, titanium-zinc etc. will have to be cleaned and pre-treated with Sika Aktivator-205. After a flash-off time of at least 15 minutes & then apply Sika Primer-3N by using a brush and allow a flash-off time of at least 30 minutes, with a maximum of 8 hours before sealing.

    PVC has to be cleaned and after that, treated with Sika Primer-215 by using a brush. Before sealing, allow a flash-off time of at least 30 minutes & no longer than 8 hours.

    Porous surfaces

    Porous surfaces have to be primed with Sika Primer-3 N using a brush. Before sealing, allow a flash-off time of at least 30 minutes & a maximum of 8 hours.

    For more detailed instructions, please read the Product Data Sheet for pre-treatments or alternatively, contact our Technical Department. Primers are used as adhesion promoters. They do not replace the correct cleaning of the surface nor do they improve its strength significantly.
