    All surfaces must be dry and clan for application of Everbuild S50. Glass and aluminium should be cleaned with a solvent cleaner before application.

    However, some surfaces may require priming. Therefore a small area should be tested first.

    If the joint is likely to be immersed or if adhesion is weak (especially on porous surfaces) use EVERBUILD SILICONE PRIMER P1. Also, to improve adherence (if required) to non-porous surfaces, prime with EVERBUILD SILICONE PRIMER NP2. LIMITATIONS

    – Do not use in conjunction with Bitumen or Asphalt, use Everbuild Weather Mate.
    – Do not use on anodised or chrome plated shower trims, use Everbuild 450.
    – It is the user’s responsibility to determine suitability for use.
    – Not to be used on natural stone, as S50 is not anti leaching and will stain after time.

    We have a number of tools on our website that would assist with the application of this product. We would recommend using a PC Cox Skeleton Gun to apply & a Bond-it Tooling Kit to aid in providing a professional finish.

    Always refer to the technical data sheet or speak to someone at Sealant Supplies for advice.

  • Sika Sikasil Pool


    Sika Sikasil Pool is a one-component, neutral cure silicone, specifically designed for use in swimming pools and continuously wet areas.


    – Excellent water resistance
    – High chlorine resistance
    – Excellent resistance to fungal attack. In other words, it is non-corrosive


    Sika Sikasil Pool is a sealant designed for joints in and around frequently wet areas between tiles, concrete, glass and metals. However, different prep work may apply.


    – Excellent water resistance
    – High chlorine resistance
    – Excellent resistance to fungal attack
    – Non-corrosive
    – High elasticity and flexibility


    The substrate must be clean, dry, sound and homogeneous, free from oils, grease, dust and loose or friable particles. Sikasil Pool 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 pretreatment procedures shall be followed:

    Other metals, such as copper, brass and titanium-zinc

    These also have to be cleaned and treated using Sika Aktivator-205, wiped on with a clean towel. After the necessary flash-off time, use a brush to apply Sika Primer-3 N and allow a further flash-off time of at least 30 minutes to 8 hours before sealing the joints. Also, when using on PVC, it has to be cleaned and pre-treated using Sika Primer-215.

    Porous substrates

    For instance, areas such as concrete, aerated concrete and cement-based renders, mortars and bricks shall be primed using Sika Primer-3 N applied with a brush. Before sealing, allow a flash-off time of > 30 minutes (< 8 hours).

    For more detailed advice and instructions, please contact the local Sika Technical Services Department.


    After the necessary substrate preparation, insert a suitable backing rod to the required depth and apply any primer if needed. After that, insert the cartridge into the sealant gun and extrude Sikasil Pool into the joint. Make sure that it comes into full contact with all sides of the joint and avoids any air entrapment.

    To ensure adequate adhesion, make sure Sika Pool is tooled firmly after extruding product into the joint. 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 to help smooth the joint surfaces.
