Limits & notes
For applications under the DIBt approval only the colour black is intended; concrete grey is intended for all other applications. In plants subject to approval, only skilled workers of a specialist company under § 62 AwSV trained by the approval holder may install it. Not suitable for glass sealing, swimming pools or substrates made of PE, PP, PTFE, polystyrene, bitumen or plasticiser-containing materials such as EPDM. Not resistant to alcohols, concentrated acids and alkalis or chlorinated and aromatic hydrocarbons; high NOx concentrations from faulty ensiling also cause damage. Do not paint over joints.
Hazard statements: Danger. H334 May cause allergy or asthma symptoms or breathing difficulties if inhaled. EUH211 Warning! Hazardous respirable droplets may be formed when sprayed. Do not breathe spray or mist. Safety data sheet available from the manufacturer.
Application & tips
Prepare the substrate so that it is sound, clean, dry and free of oil, grease and cement laitance. On concrete, apply Sika Primer-115 thinly and allow 30 minutes to 8 hours to flash off. Form movement joints at least 10 mm wide and backfill with a closed-cell PE backer rod. Apply at +5 to +40 °C air and substrate temperature; the substrate must be at least 3 °C above the dew point. Tool with Sika Tooling Agent N; skin formation after 5 to 6 hours, through-curing around 2 mm in 24 hours (+23 °C, 50 % RH). Contains isocyanates. Apply only with disposable nitrile gloves and safety goggles and ensure good ventilation; cured sealant can only be removed mechanically. Since 24.08.2023, professional users require training under REACH Annex XVII No. 74. Clean tools immediately with Sika Remover-208. Store dry at +10 to +25 °C; shelf life 12 months from production when unopened.
