ProJoint TileJam 3kg Onyx Black combines a polymer-modified cement blend with a smooth-setting formula designed for both walls and floors. It creates neat joints and supports quick application without clinging to tile surfaces, helping you achieve a clean finish on every project.

The Onyx Black shade offers strong contrast against lighter tiles and complements darker tones for a seamless appearance. Its 3kg size makes it well-suited for small installations, touch-ups, or areas where precision in colour matching is required.

Who This Product Is For

This 3kg pack is designed for DIY users, tilers, and contractors working on smaller tiling projects or repairs. It suits those who need a manageable quantity for touch-ups, colour-matched regrouting, or compact installations where buying larger bags would be impractical.

The product is appropriate for bathroom and kitchen updates, exterior paving repairs, feature walls, and other small-scale tiling jobs that require a fast-setting, mould-resistant grout in a deep black shade.

How This Fits Into a Typical Job

This grout is used during the finishing stage of a tiling project, after tiles have been fixed and the adhesive has cured. It fills the joints between tiles, providing both a visual finish and protection against water ingress and dirt accumulation.

The process involves cleaning the joints, mixing the grout to a smooth consistency, working it firmly into the gaps, then removing excess before it fully sets. Correct application ensures joints remain clean, stable, and resistant to staining over time.

How to Use

1. Surface Preparation: Clean and dry the joints, removing dust, debris, and contaminants.
2. Mixing: Stir until a smooth, even consistency is achieved.
3. Application: Work the grout firmly into the joints using a float or squeegee.
4. Residue Removal: Once the grout begins to firm, wipe off excess with a damp sponge rinsed frequently.
5. Curing Time: Ready for light traffic after three hours and fully cured within 24 hours.
6. Exposure to Moisture: In wet areas, allow at least three days before exposing to constant water.

Storage & Maintenance

• Store unopened bags between 5°C and 25°C in dry conditions.
• Keep away from frost and excess moisture before use.
• Use within 18 months from the date of manufacture for best results.
