One 80 lb. (36.4 kg) bag will require up to 4 quarts (3.7 L) of water. Thoroughly mix the contents of the bag with the water, adding a little at a time if the mix is too stiff. Adding too
much water will weaken the mix and may cause cracking in the surface.
Butter the ends of the brick or block with the mortar and place them into a bed of mortar. Level while gently tapping into place. When used in tuckpointing, after compaction into the joint,
allow the fresh mortar to set before striking with a jointer tool.
Keep the placed material damp in hot weather conditions to aid curing. Protect the mortar from freezing for at least 24 hours after placement.
