How This Fits Into a Typical Job

This jointing compound is used after porcelain paving slabs have been installed and properly bedded. It represents the finishing stage where joints between slabs are filled to complete the paved surface.

The process involves preparing the surface, mixing the compound with water, applying it to fill joints, allowing it to set, then cleaning excess material before final polishing. It creates the final sealed appearance and structural integrity of the paved area.

How to Use

1. Preparation
   • Wet the paved surface thoroughly. All paving must be clean and solid.
   • For new porcelain installations, apply a bonding slurry primer before bedding the slabs onto mortar.
2. Mixing
   • Add 2.25 to 2.55 litres of water to one 15kg bag in a clean bucket.
   • Mix using a drill with a paddle attachment until fully combined.
   • Allow the mixture to stand for a brief moment after mixing.
3. Joint Filling
   • Pour the product onto the wet paving.
   • Use a squeegee to spread and push the mix into the joints.
   • Fill completely, topping up where necessary.
4. Setting Time
   • Leave the product to sit for 30 to 60 minutes before removing excess.
5. Cleaning
   • Wipe off any residue with a damp sponge. Take care not to pull material from the joints.
6. Polishing
   • Once hardened, polish the surface lightly with a soft cloth.
7. Curing
   • Allow 72 hours for full cure under normal weather conditions.

Storage and Maintenance

• Store unused product in sealed containers in a dry, cool location.
• Rinse tools with clean water after use.
• Clean the paving with a suitable patio wash, such as Karcher Stone Path, Patio and Facade Cleaner, once the joints have cured.
• Check finished joints periodically and refill as needed if gaps appear.
