Who This Product Is For

This joint filler is designed for landscapers, gardeners, or experienced DIYers working with dark natural stone or modern paving materials. It suits those seeking a clean, black joint finish for outdoor hard landscaping projects.

It is appropriate for finishing patios, footpaths, terraces, and courtyards where darker granite, slate, or similar stone is used and a crisp joint appearance is required.

• Ready to Brush In: Apply without mixing or specialist tools.
• Permeable Finish: Allows surface water to drain away cleanly and efficiently.
• Weather Compatible: Works even in light rain or damp air.

Practical Applications

This black resin mix is best suited for use with dark paving slabs, natural stone, and modern garden designs. It’s ideal for footpaths, paved courtyards, and terraces with porous bedding. Use with joint widths of 3mm or greater for optimal results.

Not Suitable For

• Joint gaps narrower than 3mm
• Light-coloured paving where a black contrast would be undesirable

How This Fits Into a Typical Job

This product is used during the final surfacing stage of a paving installation, after slabs have been laid and bedded. It fills the joints to complete the surface, providing a finished look and functional drainage.

The compound is applied to clean, damp joints, brushed in, and left to cure, forming a solid fill that seals the gaps and reduces future maintenance.

How to Use

1. Wet the Surface: A light soak helps spread the filler evenly.
2. Apply from Tub: Tip out the contents directly onto the wet slabs.
3. Sweep Into Joints: Use a stiff brush for even coverage.
4. Compact if Needed: Press down where deeper fill is required.
5. Rinse Lightly: Wash away surface residue without disturbing joints.
6. Let It Set: Allow 24 hours for the compound to cure fully.

Storage and Maintenance Tips

• Store unused product submerged in water and sealed tightly.
• Keep in a dry place between uses.
• Clean the area regularly to prevent moss or algae from forming.

Add the ProJoint Fusion – Black compound to your paving job and finish with sharp definition, improved drainage, and a smooth black finish that stands out for all the right reasons.
