What’s the difference between Type S and N mortar?
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.
What is type in mortar used for?
Type N Mortar Mix
It is considered to be a general-purpose mix, useful for above grade, exterior, and interior load-bearing installations. 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.
Is Type N mortar stronger than Type S?
Type S mortar is a medium-strength mortar (minimum 1800 psi). Since it is stronger than Type N, it can be used for below-grade exterior walls and other exterior projects projects like patios.
Can I use type N mortar on old brick?
According to “Masonry Systems,” Types N and O are the most flexible and the best for bonding with old brick. Types M and S are much stiffer and won’t bond as well with soft brick. Choose Type N or Type S mortar when the brick is routinely exposed to freezing conditions.
What is masonry cement type N used for?

Can you Parge with Type N mortar?
Type S Masonry mortar is recommended for use in all masonry be- low grade as well as in exterior load bearing walls requiring high strength. Type N Masonry Cement or Type S Masonry Cement can also be used in parging and stucco work.
Why does my mortar keep cracking?
Many times the cause or mortar cracking in newly laid brick is dry bricks soaking up the moisture from the mortar too quickly. If you wet or soak the bricks an hour or so before laying them the moisture in the brick will prevent rapid drying of the mortar and help achieve a stronger, better, bond.
What is the difference between Type S mortar and Portland cement?
Type S contains 2 parts portland cement, 1 part hydrated lime and 9 parts sand. Type N is described as a general purpose mortar mix and can be used in above grade, exterior and interior load-bearing installations. It is also associated most commonly with soft stone masonry.
What type of mortar is the strongest?
Type M mortar is the strongest of the four, and has a compressive strength of 2500 PSI. Type M mortar should be used when the structure has to withstand high gravity and/or lateral loads. Type M mortar is also a good choice for hard stone projects where the compressive strength of the stone is greater than 2500 PSI.
How do I choose a mortar?
Mortar selection should also be based on properties like durability, bond strength, flexibility, moisture resistance and how easy it is to work with. Each job requires a mortar that balances work requirements with the performance of the completed project. And other details are also important.
What is a perp in bricklaying?
The term ‘perpend’ refers to the vertical joints between blocks or bricks that have been laid in a horizontal course to form a wall. Perpends are normally filled and sealed with mortar.

Can I add lime to Type N mortar?
But adding hydrated lime to the mortar mix can be beneficial. The plasticity or workability of the mix is better. When hydrated lime is added to the mix, the sand and the cement do not separate. The final mortar also is more waterproof.
When did they stop using lime mortar?
Lime mortar has been used in construction since the time of the ancient Egyptians around 4,000 to 6,000 BC. It continued to be used until the 19th century, when the introduction of Portland cement led to the emergence of cement mortars, which were faster setting and had a higher compressive and flexural strength.
