Type O and Type K are recommended for most historic masonry applications. Mortar often contains hydrated lime; grout usually contains little if any hydrated lime (ASTM C 476, Specification for Grout for Masonry, allows up to 1/10 part lime to 1 part cement). Q: I recall that earlier versions of the Brick Industry Association's Technical Note 28B recommended that mortar should be Type S for brick veneer over steel stud back-up walls when wind loads exceed 25 psf, and that only portland cement-lime mortars should be used. Type "S" is "structural", which means it will bond tightly to masonry (brick, stone, cast stone, etc. Find N mortar mix at Lowe's today. Mortar is the bonding material between bricks, concrete block, stone, and many other masonry materials.It is made from Portland cement, lime, sand, and water in varying ratios.

Here in Texas, where we have active soils, I use "N" (because if "Z cracks" develop in a brick wall, the masonry can be raked out and replaced) for everything except for attaching cast stone. I noticed that in the December 2005 version this language was modified. Can be used in both interior and exterior construction. • Type S: General all-purpose mortar with high flexural bond strength; 28-day compressive strength of 1,800 psi. Type N mortar can endure high temperatures and rough weather, thanks to its composition of one part cement, one part lime, and six parts sand. For example, empirical design of foundation walls requires Type M or S mortar and glass unit masonry requires Type N or S mortar (ref. other Limitations When selecting a DESIGNMIX Professional-Grade Mortar Mix for particular type and properties, follow local building code requirements.

Compressive strength, bonding and flexibility work together while holding mason… For general use of mortars for brick and block, including brick veneers, in non-load bearing applications. Type S mortar is a medium-strength mortar (minimum 1800 psi). Type S has high compressive strength (1800 psi) but adds high tensile bond strength. It also works well when used to construct brick patios, pavements, and retaining walls. Most Type S Mortar mix that you can use for grout comes in a powdered form that you mix with water. Type N mortar withstands high heat, low temperatures, and severe weather and is considered to be a general-purpose mix. Mortar (Type S)… This is a mortar that has a minimum of 1800 psi. 14. Mortar should not be substituted for grout unless the substitution is allowed by the architectural specifications. Type M, S, N, O, K, and L. Type M is the strongest and hardest and contains the highest percentage of Portland Cement while Type L has no Portland Cement and is the softest. S contains 2 parts portland cement, 1 part hydrated lime and 9 parts sand, and yields maximum flexural strength to fight wind, soil pressure or earthquakes. The process is known as gauging. In general, Type S mortar is used for structural or foundation work, but Mark finds that the Type N works better in this application because it’s softer and will accommodate some movement in the foundation. Type N or Type S mortars are generally used for installing stone veneer.

It is great for semi-soft masonry and has a flexibility to it that makes it not crack as easily as the stronger mortars. Type N. Type N mortar is common, general purpose mortar that cures to a minimum strength of 750 psi. 9: Type S mortar. Available Mortar Types. 1). ), while type "N" is "non-structural", which means it won't bond tightly to masonry. Since it is stronger than Type N, it can be used for below-grade exterior walls and other exterior projects projects like patios. I am trying to match mortar on a 50's stone house and it is darker than the type s mortar we used on the foundation.
