Revitalise old grout without costly replacements: Karl Dahm’s grout colourant restores even heavily soiled or yellowed grout lines to a like-new look. Especially in high-traffic areas like bathrooms or kitchens, discoloured grout is an aesthetic issue that can be quickly, cleanly and permanently corrected.
Key benefits:
Water-based grout colour with excellent coverage
No need to tape tiles
Long-term protection against staining, oil, water and cleaning agents
Quick application, high surface coverage
Grout colouring instead of re-grouting saves time and money – ideal for refurbishments and renovations!
Repair rather than replace: Minor damage to tiles, natural stone or ceramics doesn’t warrant a full replacement. The Fliesendoktor offers a professional method for repairing scratches, chips, drill holes or cracks.
Common challenges:
Repairing large format tiles without removal
Restoring the appearance of textured or gloss surfaces
The solution:
Step-by-step repair technique (cleaning, bonding, filling, light curing, polishing)
Various methods tailored to different materials (e.g. transparent, retouching, or crystal techniques)
Professional repair set with matched components for lasting results
Added value: Tiling professionals can join regular training seminars to master the Fliesendoktor system.
DryTiling changes the game in tile installation: dry, quick, residue-free and adhesive-free. Especially suitable for rental properties or temporary installations, this system provides a modern alternative to traditional wet-lay methods.
Advantages of DryTiling:
Up to 50% time savings
No waiting for adhesive to dry
Immediately walkable
Reusable tiles without damaging the subfloor
Ideal for large formats (e.g. 120 x 120 cm)

DryTiling is compatible with underfloor heating – with only minimal heat transfer delay.
