Grout CERESIT CE 40 Aquastatic waterproof flexible grout, Manhattan, 5 kg

CERESIT CE 40 Aquastatic waterproof flexible grout in Manhattan color is a cement-based joint filler formulated for use with ceramic, porcelain and natural stone tiles. Supplied in a 5 kg pack, this grout is designed to deliver long-lasting elasticity and moisture resistance in areas exposed to water and movement. It is intended for narrow to medium joint widths and can be used in both renovation and new installation projects where a durable, water-repellent finish is required.

Advantages

The grout combines waterproofing properties with flexible performance to reduce the risk of cracking in tiled surfaces subject to slight substrate movement. Its formulation provides good adhesion to tile edges and repels water from the joint area, helping to maintain grout integrity and reduce staining. The Manhattan shade offers a neutral, warm tone that blends with a variety of tile finishes. Supplied as a ready-to-mix powder in a 5 kg package, it is suitable for smaller to medium jobs and straightforward storage on site.

Suitable for

• Interior wet areas such as bathrooms and showers
• Kitchens and splash zones around sinks and worktops
• Balconies and terraces protected from heavy structural movement
• Renovation projects and new tile installations with narrow to medium joint widths

When it may not be suitable

The CE 40 Aquastatic grout is not intended for very wide joints or for filling large expansion joints; specialized elastomeric sealants or polysulfide/PU products are more appropriate in those cases. It is also not a substitute for movement joints or structural waterproofing systems required in heavy-duty exterior applications or areas with significant thermal or structural movement.

Key specifications

• Type: Cement-based flexible grout with waterproof properties
• Color: Manhattan (neutral warm tone)
• Pack size: 5 kg
• Recommended joint width: narrow to medium joints
• Suitable substrates: ceramic, porcelain, natural stone tiles
• Intended use: interior wet areas and protected exterior areas

How to use

Mix the powder with clean water according to the manufacturer's instructions until a homogeneous, lump-free consistency is achieved. Apply the grout with a rubber float, pressing into joints at an angle to ensure full compaction. Remove excess material from tile faces with the float and perform initial cleaning with a damp sponge once the grout begins to firm but before final set. Allow the grout to cure for the time recommended by the manufacturer before exposing to water or heavy traffic. Follow safety and ventilation guidelines during mixing and application.

What to consider before purchase

• Confirm joint width and tile type to ensure suitability for narrow to medium joints
• Verify color match with selected tiles and consider testing on a small area
• Assess area size to determine the number of 5 kg packs required
• For movement joints or very large gaps, plan for appropriate sealant or joint system

Usage recommendations

For best results, store the product in a dry place and mix only the amount that can be applied within the workability time. Apply in temperatures recommended by the manufacturer and protect newly grouted joints from direct water exposure until fully cured. When working with natural stone, test compatibility and consider sealing the stone to prevent staining.
