Ceresit CE 40 Aquastatic waterproof flexible grout in Antracyt (2 kg) is a ready-mixed joint filler formulated for use with ceramic, porcelain and natural stone tiles. The product combines elasticity and water resistance to protect tiled surfaces in wet areas such as bathrooms, kitchens and balconies. Supplied in a compact 2 kg package, the grout is intended for narrow to medium joint widths and is suitable for both indoor and outdoor applications where moisture exposure and slight substrate movement are expected.
Advantages
The grout offers a balance of flexibility and water resistance to reduce risk of cracking and water ingress in tiled installations. Its ready-to-use paste consistency simplifies application and reduces preparation time. The Antracyt shade provides a dark, neutral joint color that complements a wide range of tile surfaces and hides typical soiling. Formulation features suited for wet-room use contribute to longer-lasting joints under regular exposure to water.
Suitable for
- Filling joints between ceramic and porcelain tiles.
- Grouting natural stone tiles where a flexible, water-resistant joint is required.
- Wet rooms such as bathrooms and showers.
- Kitchens, utility rooms and balconies subject to moisture.
- Indoor and outdoor tiled surfaces with narrow to medium joint widths.
When it may not be suitable
This grout is formulated for narrow to medium joint widths and may not be appropriate for very wide joints or deep repairs that require special cementitious mortars. It is a ready-mixed paste designed for common tile substrates; highly irregular or unstable substrates that require structural repairs should be addressed before grouting. For applications needing specific chemical or high-temperature resistance, check technical data or select a grout designed for those conditions.

How to use
Ensure tile surfaces and joints are clean, stable and free of dust, adhesive residues or contaminants. Open the container and stir the paste if necessary to achieve uniform consistency. Apply the grout using a rubber float or grout trowel, pressing material firmly into joints and removing excess from tile faces. After initial setting, wipe tiles with a damp sponge to clean grout residue and shape the joint profile. Allow adequate curing time according to ambient conditions before exposing the surface to heavy moisture or traffic.
What to consider before purchase
- Verify that joint width falls within the product's recommended narrow to medium range.
- Confirm color choice (Antracyt) suits the tile and desired aesthetic.
- Estimate quantity needed based on tile size, joint width and area to be grouted.
- Ensure substrate is prepared and any structural issues are repaired before grouting.
Usage recommendations
Store the product in a frost-free environment. Apply at moderate temperatures and avoid direct sunlight during application to allow consistent curing. Test the grout on a small area or sample tile to confirm color and compatibility with tile surfaces before full application.
