*Primer as in the standard version. For shower trays: Aquastop waterproofing is recommended on the substrate, directly followed by EP21 or Keragrip Eco Pulep.
Important: The R11 DOES NOT receive a protective layer (Gel + Xtreme). The open texture ensures slip resistance but is harder to clean and less durable than the standard version.
