Who This Product Is For

This product is suitable for tradespeople working on commercial or residential paving projects, as well as homeowners undertaking garden and patio improvements.

It works for projects involving paths, patios, edging, and outdoor areas where a clean, defined finish is needed.

Practical Applications

This black resin grout is well-suited for premium paving installations that feature darker tiles or slabs. It works for urban patios, monochrome outdoor kitchens, and courtyard settings where contrast or subtlety is needed.

How This Fits Into a Typical Job

This jointing compound is applied after paving slabs have been laid and set. It represents the finishing stage where joints between slabs are filled to create a complete, weather-resistant surface.

The application follows a systematic approach: surface preparation, compound application, compaction, and final cleaning before allowing the material to cure.

How to Use

1. Pre-Wet the Area: Saturate the surface to protect it during the application process.
2. Apply and Sweep In: Spread the mixture across the joints with a brush, pressing it in firmly.
3. Compact Thoroughly: Work the compound deep into the gaps for a solid set.
4. Rinse Off Lightly: Use water to clear residue without washing out the joints.
5. Let it Set: Keep the area clear of traffic and rain for at least 24 hours.

Storage and Maintenance

• Replace any unused material in the tub and cover it with water to extend the shelf life.
• Store indoors and away from frost to maintain quality.
• Clean tools immediately after use to avoid build-up.
