Mortar mix ratio for stone
Pour half a bucket of clean water into the mixer. Then, pour four buckets of sand into the mixer to produce standard patio mortar mix or three buckets for a patio pointing mix. For both mixes, add one bucket of cement. If applicable, add the plasticiser according to the instructions on the packaging. Allow it to run for thirty seconds until it ...The mixing is different (mix ratios, no admixtures etc.) and the aftercare/curing requires more as lime pointing needs to be tamped/beaten back with a stiff brush as this action removes excess mortar and sets the mortar into the joint.
