Epoxy grouting is one of the most demanding tasks in the tiling trade. The special composition of epoxy resin requires precision, speed and reliable tools. At Karl Dahm, you’ll find a comprehensive selection of professional products developed specifically for epoxy grouting – from grout floats and sponges to cleaning tools.
Epoxy grout is ideal wherever surfaces are exposed to extreme conditions – such as commercial kitchens, swimming pools, public washrooms or outdoor areas. Its advantages include:
Exceptional durability: Epoxy is waterproof, chemical-resistant and highly resilient to mechanical stress.
Hygienic and easy to clean: The closed, smooth surface repels dirt and simplifies cleaning.
Long-lasting performance: Compared to cementitious grouts, epoxy grouts maintain their integrity even under heavy use.
Despite its benefits, working with epoxy grout poses some challenges:
Short working time: Epoxy cures quickly. Any excess material must be removed promptly and thoroughly.
High viscosity: The resin is thick and harder to spread than traditional grout.
Intensive cleaning required: Without the right tools, stubborn residues or streaks may remain on the tile surface.
The solution: Specialised tools from Karl Dahm tailored to epoxy applications.
To apply epoxy grout cleanly and efficiently, Karl Dahm offers a range of high-quality floats:
Professional Float, Art. No. 10485
Acid-resistant fine rubber coating for lasting durability
Sharp edges for clean application without residue
Ergonomic handle for fatigue-free work
Size: 26 x 10 cm – suitable for narrow working spaces
Additional models with distinct features:
Soft-Grip Float (black), Art. No. 11779 – durable moss rubber surface
Special Float with green coating, Art. No. 10478 – for extra abrasion power
Duo Float, Art. No. 11802 – features both hard and soft sides
Click Float, Art. No. 12142 – replaceable pad for sustainable use
All floats are engineered for heavy-duty performance and superior handling – making epoxy grouting faster and cleaner.
Epoxy residues must be removed within a short timeframe after application. The right cleaning tools are essential:
Viscose Sponge Float, Art. No. 10783
Highly absorbent and fine-pored – perfect for the final rinse
Streak-free finish on tiles
Ergonomic and easy to handle – even during extended use
Also available:
Replacement sponges for float pads, e.g. Art. No. 11763
Moss rubber pads, e.g. Art. No. 10480 (black) or 10479 (green)
Ensure your epoxy grout lines are not only strong but also visually perfect.

Epoxy grout is a two-component resin system that cures into a hard, non-porous, and extremely durable surface. This makes it highly resistant to moisture, chemicals, and mold growth. Cement grout, on the other hand, has a porous structure that can absorb water and dirt, which may lead to discoloration, efflorescence, or structural damage over time. Epoxy grout is therefore ideal for high-moisture or high-traffic areas such as showers, swimming pools, commercial kitchens, and floors that require long-lasting durability.
When working with epoxy grout, it is essential to grout in small sections and wipe off excess material right away. Epoxy has a limited pot life and begins curing shortly after mixing. Proper preparation, correct mixing, and the use of the right installation tools will make the job easier. Using a sharp-edged grout float and a special sponge helps avoid haze and ensures clean, even joints. Having clean water ready is crucial for effective final washing.
To achieve professional results when applying epoxy grout, the right tools make a major difference. A high-quality epoxy grout float allows you to firmly press the grout into the joints and cleanly scrape off excess material. A fine-pored sponge is needed to evenly wash the tile surface during the final cleaning stage, preventing haze and ensuring smooth joints. Keeping tools clean throughout the process prevents cured residue from affecting the finish.
Epoxy grout cures into a very hard and non-porous finish, which is what makes it so durable. However, this also means that once it is fully hardened, corrections are complicated and sometimes impossible. Removing or reshaping hardened epoxy requires special equipment and can be extremely time-consuming. For this reason, careful, precise, and well-planned application during installation is essential.
The working time—also called pot life—depends on the specific epoxy grout and the temperature of the environment. Within this time frame, the mixed material remains workable. Warmer temperatures shorten the working time significantly, while cooler temperatures extend it. For optimal workflow, it is best to prepare the workspace and tools in advance to avoid unnecessary delays.
Because epoxy grout projects vary widely in scale and application, most tools are offered individually instead of as fixed kits. This allows professionals and DIY users to put together exactly the tools they need—whether for small shower walls or large commercial flooring projects.
Epoxy grout can only be cleaned off tools easily while it is still fresh. As soon as the material begins to cure, removal becomes significantly more difficult. Therefore, wash the float, sponge, and bucket repeatedly during and immediately after use. Allowing epoxy to dry on tools can permanently damage them.
Epoxy grout is generally safe to use as long as basic safety precautions are followed. Avoid direct skin contact and ensure adequate air circulation during application. It is recommended to wear protective gloves and read the manufacturer’s safety instructions to ensure proper handling.
Epoxy grout can be used with many natural stone materials, but certain stones can become permanently darker or take on a “wet look.” To avoid unwanted changes in appearance, always apply epoxy grout to a test area first. This helps determine whether the stone reacts to the resin or if an alternative product may be better suited.
Temperature greatly affects the workability and curing of epoxy grout. At temperatures between 18°C and 25°C (64°F to 77°F), the material spreads easily and maintains a balanced pot life. Higher temperatures cause faster curing, requiring quicker work, while lower temperatures slow curing and may extend installation time. Maintaining a stable room temperature ensures consistent results.
