EVERFLEX SILICONE 335 CONSTRUCTION is a low modulus, reactive curing silicone sealant that cures quickly to reduce dirt pick up. It remains permanently flexible, forming a weather tight rubber-like seal. Silicone 335 meets ISO11600 F and G 20LM.


All surfaces must be clean, dry and dust free. All loose or flaking surface coatings, and old sealant and mastic joints, should be removed before application. Glass, metal and aluminium should be cleaned with a proprietary solvent cleaner prior to application for optimum adhesion. Porous surfaces may require priming – a small area should be tested first.

  • Faster curing than conventional low mod sealants.
  • Extremely low dirt pick up.
  • Flexible – movement accommodation of +/- 20%.
  • Waterproof seal
  • Contains a powerful anti fungal compound to prevent mould growth.
  • Certified under the harmonized European standard EN15651 for façade, glazing, cold climate and sanitary applications in compliance with the Construction Product Regulation
