FAQ

  • Which sealant after 5 years? For elastic connection/movement joints we recommend replacement with a system‑compatible, neutral‑cure silicone or hybrid, depending on UV exposure and substrate.
  • Primer required? Yes for mineral/absorbing substrates and critical plastics to ensure reliable adhesion.
  • Joint width/depth? Rule of thumb: width ≈ 2× depth, use backer rod, avoid three‑side adhesion.
  • Maintenance? Visual check every 2–3 years; cracks, edge debonding or mould indicate replacement.
  • Material choice for Flat roof – connections? Indoors: neutral‑cure silicone (sanitary with fungicide). Outdoors: UV‑stable hybrids/PU according to the system.
