Ensure all joints are dry, free from weeds, dirt or debris. Joints must have a minimum width of 5mm throughout the full depth and should be at least 25mm
Rake though any compacted material removing any small lumps then using a soft broom, work the Ecofil into the joints making sure that each joint is completely filled.
Compaction will improve the long-term durability of the joints. A finishing tool may be used to compact and achieve a traditional finish.
Ecofil will cure within 24 hours giving you a fantastic, maintenance-free paved area.
