Type N Mortar Mix
It is also the preferred mortar mix for soft stone masonry. Type N is the mortar most often used by homeowners and is the best choice for general application. It typically achieves 28-day strength in the range of 750 pounds per square inch (psi).
What kind of cement should I use for a stone wall?
If you’re building a retaining wall, use a blended mason mix, which includes the heavy-duty mortar type S masonry cement and graded sand. This is high-strength, contractor-grade and pre-blended mortar. This is also ideal for stone columns.

If you’re looking for a reliable, general-purpose mix, type N mortar might be the winner. This mortar mix has a medium compressive strength and consists of 1 part Portland cement, 1 part lime, and 6 parts sand. It typically achieves 28-day strength at approximately 750 psi.
What kind of mortar do you use for stacked stone?
If the stacked stone will be load-bearing, use mortar type S, which has a compressive strength of 1,800 pounds per square inch. Mortar type N, with a compressive strength of 750 pounds per square inch, is sufficient if the stone structure will not need to bear weight.
Do you mortar retaining wall?

What is the difference between Type N and Type S mortar mix?
Type N mortar is a general-purpose mortar that provides good workability and serviceability. It is commonly used in interior walls, above-grade exterior walls under normal loading conditions, and in veneers. Type S mortar is used in structural load-bearing applications and for exterior applications at or below grade.
Is masonry cement the same as mortar?
Masonry cement is mixed with sand and water to produce mortar for brick, block and stone construction. Mortar is the bonding agent that forms individual masonry units into a wall. Other applications include stucco and cement-based plasters.
