First step

Once your paving is completely dry, mix the paving mortar with a shovel and sweep the mix into the joints with a soft brush down to the bottom edge of the paving or flagstones. Brush the paving mortar into the joints using movements diagonal to the joint cross-section as you would with conventional joint-filling sand.

Second step

For best results, use a surface vibrator after filling the joints with paving mortar. Run your surface vibrator over the paving at least twice.

Third step

Check the solidity of the joints with a scraper, which you should be able to push a few millimetres into the joint. If necessary, fill the joint up again. Sweep off all of the excess material from the paving.

Fourth step

Use a soft brush to remove any fine dust from the paving.

Fifth step

Moisten the edges using a garden hose and spray nozzle. Set the nozzle to fine spray to make it easier to set the ideal water amount. Don't try to do this with a watering can. Repeat this after a quarter of an hour.

Sixth step

Check the moistening effect by scratching a little into the joint. Make sure that the joint has been moistened to the full flagstone or paving stone height. Avoid overwatering, as this might wash out the binder, ruining the joint properties and possibly discolouring your paving.

The joint will take twenty-four hours to cure in the normal temperature range (+20°C in dry weather), but curing times will increase in colder temperatures and decrease in warmer temperatures. The fresh joint will withstand light rainfall or dew while curing, but this will lengthen curing and drying times.

Remove any potentially troublesome cement residues on the paving after two days using a stiff brush and soapy water.
