Firestop – refurbishment

Firestop – refurbishment in Zürich & surroundings – professional, durable and documented.

Eurofugen – Firestop – refurbishment in the Zürich area. We prepare the joint plan, verify substrate strength and movement, and select an approved system (neutral‑cure silicone, hybrid/MS polymer, PU) in strict accordance with manufacturer specs. Focus: Intumeszierend – Aufschäumen. Planning priority: Bewegungsraster & Anschlussdetails. Standards: Approved systems per manufacturer classification; documentation per seal.

Quality & acceptance

  • Uniform, slightly concave finish profile
  • Ensure bond at two flanks; prevent three‑sided adhesion using PE backer rod
  • Crisp edges without staining
  • UV/weather‑resistant sealants fit to exposure
  • Joint width/depth per plan (≈ 2:1)

Planning & preparation

Mock‑ups with cut‑and‑pull checks provide pre‑approval. We verify weather and dew point; application only on dry, load‑bearing flanks. Primers are chosen per substrate absorption (e.g., clinker, fair‑faced concrete, fibre cement). Detailing at edges, reveals and penetrations is recorded in drawings. Joint layout based on panel sizes and anticipated movement; critical edge zones are eased. Create square, sound flanks, define depth and install the closed‑cell backer rod precisely.

Application & control

Transitions at profile joints and material changes are re‑worked separately. Random cut‑and‑pull checks, width/depth measurements and visual inspection are recorded. Apply sealant without bubbles, fill the joint evenly and tool to a slightly concave profile. Maintain movement capability; remove masking in due time and verify edge adhesion. Use UV‑stable systems and protect adjacent surfaces from contamination.

Planning & preparation

Clean substrates, define edges and limit bond areas; primers & backer rod are matched to substrate and width. Mock‑ups and dew‑point checks secure approval. Interfaces are coordinated before start.

Application & control

Apply sealant bubble‑free, tool evenly and control dimensions. Check edge adhesion, remove masking in time and re‑work transitions neatly. Everything is recorded.
