With proper care, the grout color lasts for several years indoors.
Karl Dahm’s grout color typically lasts for several years in interior areas.

In high-use areas such as kitchens or bathrooms, occasional touch-ups can help maintain a fresh and clean look for a longer time.
The Tile Doctor system is particularly well-suited for repairing large-format tiles. With specialized tools and repair materials, scratches, chips, and drill holes can be fixed precisely without replacing the entire tile. This saves time and money while achieving a nearly invisible repair result.
DryTiling can be used on underfloor heating systems without any issues. The system may cause only a minimal delay in heat transfer, which is barely noticeable in everyday use. Proper installation is crucial to ensure optimal heat distribution and to avoid cavities that could reduce heating efficiency.
Quick action is essential when dealing with water damage. First, remove any standing water and thoroughly dry the affected area. Then, measure the moisture levels using appropriate devices. If the damage is extensive or moisture persists, a professional drying service should be called in to prevent mold growth and structural damage.
Karl Dahm wet vacuums are built for professional use and are highly robust. They can handle not only water but also coarse dirt, construction debris, and slurry with ease.
