Tile Joint Mortar CERESIT CE40 2 kg Melba 22 — flexible waterproof grout

CERESIT CE40 2 kg in Melba 22 is a flexible waterproof tile joint mortar formulated for filling and sealing joints between ceramic and porcelain tiles on walls and floors. The product is designed to provide elastic protection against moisture penetration and to accommodate minor substrate movements without cracking. Packaged in a 2 kg format and presented in the Melba 22 shade, this grout is intended for wet-area applications such as bathrooms and kitchens where durable, water-resistant joints are required.

Advantages

The flexible composition reduces the risk of cracking when small structural or temperature-driven shifts occur. Its waterproof formulation increases resistance to water and humidity, helping to maintain joint integrity in showers, wet rooms and splash zones. The material cures to a uniform color that complements tiled surfaces and is suitable for grout widths that match typical residential and light-commercial installations.

Suitable for

• Wall and floor joints between ceramic and porcelain tiles
• Bathrooms, showers and wet rooms
• Kitchens and splashback areas
• Residential and light commercial tiling where flexible, water-resistant joints are needed

When it may not be suitable

This grout is not intended for structural movement joints or large expansion joints where specialized flexible sealants or profiles are required. It may not be suitable for areas exposed to heavy chemical cleaning agents or continuous, high-pressure water jets without additional protective measures.

Key specifications

• Form: cement-based flexible grout
• Packaging size: 2 kg
• Color: Melba 22 (warm beige tone)
• Application: wall and floor joints
• Water resistance: formulated for wet-area use
• Suitable joint width: typical residential tile joint widths (refer to technical data for exact range)

How to use

Prepare a clean, dry joint free of dust, adhesive residues and loose material. Mix the powder with clean water to a smooth, homogeneous consistency following the manufacturer’s recommended water ratio. Apply the mortar using a rubber float, pressing firmly to completely fill the joint. Remove excess grout from the tile surface with a damp sponge before the mortar sets, rinsing the sponge frequently. Allow the grout to cure undisturbed for the time specified by the manufacturer before exposing joints to water or heavy traffic.

What to consider before purchase

• Confirm color match with tiles and order enough material for all joints to avoid shade differences.
• Verify intended joint width and surface type to ensure compatibility.
• Check drying and curing time requirements relative to your project schedule.
• Consider if additional sealing or protection is needed in high-chemical or high-pressure environments.

Usage recommendations

Use suitable protective gloves and eye protection during mixing and application. Store unopened product in a dry place at moderate temperature. Follow the manufacturer’s detailed technical datasheet for mixing ratios, pot life and cure times to achieve optimal performance.
