In a home with lime-based mortar, that water seeps away through the mortar and avoids damaging the stone or brick. The mortar used for pointing, tuckpointing, or laying any particular brick, block or stone should be guided by the inherent strengths of the particular brick, block or stone. Bond strength refers to the force required to separate the mortar from the brick. I would use type N because it contains lime and Portland and it is softer than type S. Old bricks are generally soft so a hard mortar is much harder. For this reason, when selecting a mortar, evaluate properties of each mortar type and choose that type and materials which will best meet all requirements. Type O is a low strength mortar that only cures to a minimum compressive strength of 350 psi. Without the spritz water, the dry brick and old mortar will suck out the water from the mortar too quickly. If possible, use the same type of mortar that was first used in the joints. For most tuckpointing applications on standard sized brick walls, with joint widths around 1/2", and no more than 1/2” deep you will get: Portland cement adds strength to mortars, but limits flexibility.
