• Open the bag of patio jointing compound and pour out just enough compound to cover 2-3m² at a time. Once opened, use the product within 30 minutes.
• Use a soft brush or squeegee to work the brush in patio grout into the joints, then compact it using a pointing tool or rounded piece of wood, filling slightly below the surface.
• Refill and compact as needed to ensure good strength.
• Remove excess compound by brushing diagonally across the joints, ensuring any chamfered edges are exposed.
• Smooth the surface with a pointing tool.
• After 24 hours, brush off any residue using a clean, stiff brush.
• To store leftover compound, keep it sealed in the tub and fully covered with water for up to a month.
