Henkel Polybit Ceresit CE33 Joint Grout, 5Kg, Cementitious Tile Grout for 1–8 mm Joints - Siena

Ceresit CE33 Joint Grout is a ready-to-use grey cementitious grout designed to fill and seal the joints between ceramic tiles and natural stone. It is suitable for both interior and exterior applications on walls and floors and offers good adhesion, filling properties, and resistance to water and frost.

CE33 is supplied in a 5 kg bag and is a ready-to-use cementitious grout. It is designed for ceramic tiles and natural stone, suitable for interior and exterior use, with strong adhesion and filling properties. It is water- and frost-resistant and can be applied on walls and floors in wet or dry conditions.

No mixing is required—use CE33 straight from the bag. Apply in small sections using a grout bag, brush, or trowel to press the grout firmly into the joints. After joints are filled, remove excess grout and wipe the tile surfaces with a damp sponge to reveal clean joints. Allow the grout to cure as recommended (initial set typically within 24–48 hours; full cure may take several days).

CE33 is suitable for ceramic tiles and natural stone. It is generally not formulated for epoxy or non-porous specialty surfaces unless specifically recommended.

Yes. CE33 is designed for interior and exterior use and can be applied on walls and floors involving ceramic tiles or natural stone.

Initial setting occurs within about 24–48 hours, after which you can resume normal cleaning and light use. Full curing can take several days to a week, depending on conditions such as humidity and temperature.

Wear gloves and eye protection. Work in a well-ventilated area. Avoid skin contact with fresh grout and wash hands after handling. Keep the product away from children and pets and protect surrounding surfaces from splashes.

Store CE33 in a cool, dry place and keep the bag tightly closed to prevent moisture ingress. The 5 kg bag should be used within the product’s shelf life as indicated on the packaging; store away from moisture and direct sunlight.

Work in small sections, press grout firmly into joints, and remove excess grout promptly. Use a damp sponge to wipe away haze and maintain consistent joint depth. Clean as you go to prevent dried grout on the tile faces, and avoid over-wetting the grout during cleaning.

Two commonly listed alternatives on Fepy.com are: 1) Ceresit CE40 Flexible Joint Grout (5 kg) – https://fepy.com/product/ceresit-ce40-flexible-joint-grout-5kg which offers additional flexibility for movement joints, better for large slabs or substrates that may experience movement. 2) Ceresit CE29 Rapid Joint Grout (5 kg) – https://fepy.com/product/ceresit-ce29-rapid-joint-grout-5kg which sets faster for quicker projects but may require faster handling and less forgiving during application. CE33 is a standard cementitious grout, while CE40 emphasizes flexibility and CE29 speed; choose based on project needs (movement tolerance and time constraints).

CE33 is water-resistant and suitable for wet areas when installed properly, but always ensure tiles are clean, joints are fully filled, and curing conditions are met. For highly exposed or aggressive water environments, consider movement-friendly or sealing considerations per project requirements.

For cementitious grouts like CE33, it is generally not required to pre-wet tiles. Follow standard tiling best practices: ensure tiles are fully set and cured, joints are clean and free of debris, and work in small sections to keep grout adequately moist during application and finishing.

Once cured, clean tiles with mild detergent and water. Avoid harsh or acidic cleaners that can damage grout. Routine cleaning with a damp cloth or mop is usually sufficient; sealers are optional and depend on project needs and moisture exposure.
