Why R11?

R11 is the highest commercial slip resistance rating for stair nosings under DIN 51 130. The TREP-GK uses a coloured mineral grain tape — the same industrial-grade grit used in professional safety flooring. Where R10 suits residential settings, R11 is the standard specified for offices, public buildings, schools, hospitals, retail, and hospitality venues where duty of care and DDA compliance are critical.

Why Choose Retro-Fit?

  • Installs directly over existing tiles — no tile removal, no mess, no downtime
  • Transform unsafe step edges in hours, not days
  • Ideal for rental properties, landlords, and commercial refurbishment
  • Maintains the appearance of your existing staircase
  • R11 mineral grain tread provides maximum grip underfoot
  • Professional finish — purpose-built appearance

Choosing Your Colour

  • Yellow RAL 1021 — high-visibility safety yellow, standard in commercial and public buildings for clear hazard identification
  • Black RAL 9011 — high contrast, contemporary finish, maximum visibility in light-tiled environments
  • Nut Brown RAL 8007 — warm earthy tone that complements natural stone, wood-effect tiles, and terracotta
  • Transparent — clear tread that blends discreetly with your existing tiles

Suitable Applications

  • Commercial offices, corporate headquarters
  • Hotels, restaurants, and hospitality venues
  • Public buildings, schools, healthcare facilities
  • Retail and shopping centres
  • Rental properties and HMOs
  • Any existing tiled or stone staircase needing a commercial-grade safety upgrade

Installation

Clean the step edge thoroughly. Apply Kerdi-Fix adhesive to the underside and bond firmly to the existing step. No drilling or tile removal required. Matching end caps and replacement mineral grain tread tape available separately.
