Practical Applications

Ideal for patios, pathways, and outdoor entertaining areas, the mid-grey grout delivers a smart, neutral finish without overpowering your tiles. It works particularly well with mid-toned stone, slate-effect porcelain or even warmer hues that need a subtle contrast.

How This Fits Into a Typical Job

This grout is used during the jointing phase of paving installation, after slabs have been laid and levelled. The application follows a systematic approach: surface preparation, compound application, compaction, and final cleaning.

The product functions as the finishing layer that fills and seals joints between paving slabs, providing both aesthetic completion and functional protection against environmental factors.

How to Use

1. Pre-wet the Paving: Soak the tiles before starting to prevent surface staining.
2. Apply the Compound: Tip out the mix and sweep it into the joints.
3. Compact as You Go: Use a brush or trowel to press it in thoroughly.
4. Rinse Off: Lightly spray or sponge the surface to remove residue.
5. Let It Set: Leave the area for a full day before using it, or longer if it’s damp or cold.

Storage and Maintenance

• Store unused product with water covering the surface in the tub.
• Keep containers sealed and off the damp ground.
• Check curing regularly in cooler months before reusing grouted areas.
