BAUTECH EXTRATOP ENDURO™

Ultrametallic dry shake floor topping, CT-C60-F10-A1.5

EXTRATOP ENDURO™ is an ultra-metallic dry-shake topping (DST) engineered for monolithic concrete floors, including anti-static systems. It comprises premium metallic aggregates, high-strength cement, pigments, and performance additives. When applied wet-on-wet to fresh concrete and mechanically trowelled, it forms a densified, sealed, marble-textured floor with superior resistance to abrasion, impact, oil ingress, and dusting — ideal for heavy-duty environments.

Key Benefits

  • Delivers extreme hardness and up to 94% improvement in abrasion resistance over standard concrete
  • Forms monolithic, non-dusting surface suitable for cleaning and maintenance
  • Excellent resistance to oil, grease, and chemicals
  • Designed for indoor/exterior use, even in cold climates (frost-resistant)
  • Suitable for anti-static and explosive zone applications when combined with grounding and steel fiber reinforcement
  • Offers a premium marble-like metallic appearance, with optional colouring

Recommended Applications

  • Heavy-duty industrial floors (steel plants, power stations, logistics centres)
  • Anti-static environments, potentially explosive zones (with grounding & fibers)
  • Garages, service areas, mechanical workshops
  • Loading docks, airports, public utility floors

Colour Variants

  • Natural Grey (standard)

  • Optional custom colours available on request

Application & System Guidelines

  • Substrate requirements: Use fresh concrete C20/25+ with w/c ≤ 0.50, max cement 350 kg/m³, cement types CEM I/II/III, aggregate ≤ 16 mm, fine fraction ≥ 4%
  • Broadcast method: Wait until concrete shows 3–4 mm foot impressions, broadcast 3.5 kg/m², trowel, broadcast another 3.5 kg/m², finalize with machine trowel
  • Anti-static setup: Add steel fibers (≥ 20 kg/m³) and grounding tape in slab
  • Curing: Immediately apply BAUSEAL® EKO or ENDURO sealer (1 L/8–12 m²) or NANOSEAL® lithium-polymer hardener
  • Conditions: Ambient and substrate temperature between +5 °C and +30 °C; protect from rapid moisture loss
