Mix the lime with water, and leave it covered to hydrate for 24 hours. Then mix 1 part of the slaked lime to 6 parts sand and 1 part cement.
Trowel the mixture onto the wall, keeping it level and using its edge to create a smooth, flat layer of the base. After drying for an hour, rake the surface with a notched trowel to create a grooved surface. Allow it to dry for 24 hours.
Rinse the pebbles well, and drain them completely. Put them in a large bucket or a large flat bin.
Mix the top coat of 5 parts sand to 1 part slaked lime and 1 part cement. Trowel this onto the wall in a smooth even layer.
Throw the pebbles at the wall after spreading plastic sheeting below the wall. After getting an even coating, lightly press the pebbles into the wall with the flat of the trowel, and let it dry for 24 hours.
