Application Information
Instructions for use

Design Criteia

Vetoflex SS783 is a general purpose sealant and should not be used as a sealant for expansion or contraction joints in concrete and has typical acedic smell.

Cut and remove the tip of the cartridge and place it in an air operated or manual gun. Fit the nozzle and cut at 45 degrees to a suitable size for sealing the joint. Extrude the sealant firmly in to the joint. Tool flush within 5 minutes of application to ensure good contact between the sealant and the substrate.

Vetoflex SS783 should be removed from tools, equipment and mixers with Vetonit Solvent XX400 immediately after use. Hardened material can only be removed mechanically.

Surface Preparation


Clean all joint surfaces and remove any dust, unsound material, plaster, oil, paint, grease, corrosion deposits or algae. Roughen the surfaces, remove any laitence and expose aggregate by light scabbling or grit-blasting.
Oil and grease deposits should be removed by steam cleaning, detergent scrubbing or the use of a proprietary degreaser.
Any joint filler must be checked to ensure it is tightly packed and no gaps or voids exist at the base of the sealing slot before positioning a bond breaker.
The use of a bond breaker is not required in expansion joints containing cellular polyethylene joint filler, backing rod (Vetoflex PBR). For contraction joints a bond breaker tape or back-up strip must be used.
Where a particularly neat finish is required, mask the face edges of the joint before sealing and remove immediately after tooling is completed.

  • Due to the product acid base; certain materials (eg copper, lead) can be affected.
  • Do not use on natural stones like marble, granite,...(staining).
  • Direct contact with the secundary sealingof insulating glass units (insulation) andthe PVB-film of safety glass must be avoided.
  • A total absence of UV can cause a color change of the sealant.
  • In an acid environment or in a dark room, white silicone can slightly turn yellow.
  • Under the influence of sunlight it will turn back to its initial colour.
  • When finished with a finishing solution or soapy solution, make sure that the surfaces are not touched by this solution. This will cause the sealant not to adhere to that surface. Therefore we recommend to only dip the finishing tool in this solution.
  • It is strongly recommended not to apply the product in full sunlight as it will dry very fast.
  • Do not use on polycarbonate.
  • Do not use in applications where continuous water immersion is possible.
