What is Type N concrete?
Type N mortar mix has a medium compressive strength and it is composed of 1 part Portland cement, 1 part lime, and 6 parts sand. 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.
What is the difference between Type S and Type N concrete?
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 is Spec Mix Concrete?
SPEC MIX® Masonry Cement & Sand mortar is a dry preblended mortar mix containing masonry cement and dried masonry sand formulated for superior bond, water retention and board life. It is acceptable for all types of masonry construction, below or above grade when manufactured to the appropriate specification.
What does Type N mortar mix mean?
Type N Mortar Mix is a preblended mixture of sand and masonry cement or sand, lime and portland cement. For laying brick, block and stone in load bearing walls. Build walls, planters, and chimneys. For tuck pointing or repairing existing mortar joints.
What’s the difference between Type S and Type 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.
How do you mix Type N masonry cement?
Mixing Procedure:
- Put 2/3 to 3/4 of the water into the mixer.
- Add the Masonry Cement to the batch.
- Add the sand into the mixer, adding water as necessary to achieve the desired consistency.
- Mix for 5 minutes in a mechanical paddle type mixer.
What is Type N cement used for?
Type N Portland Cement Uses While Type N can protect brick and masonry veneers, chimneys, garden walls, patio walls, and soft stone masonry against severe weather, its lower strength makes it more suitable for non-load bearing walls – both interior and exterior.
What is the difference between N and S mortar mix?
Usually, a Type S mix has a high compressive strength of between 2,300 and 3,000 psi. Type N mortar mix, which contains one part portland cement, one part lime and six parts sand, is a medium compressive-strength mortar of at least 750 psi and can achieve 28-day strength between 1,500 and 2,400 psi.
What is SPEC MIX FOR?
SPEC MIX IWR mortar is specially formulated to reduce water penetration, shrinkage and efflorescence of masonry mortar joints and provide superior workability and bond strength for optimal performance.

How long does Type N mortar take to cure?
MORTAR CURE TIME Mortar typically will cure to 60% of its final compressive strength within the first 24 hours. It will then take about 28 days to reach its final cure strength. However the curing process does not always follow a universal timeline.
How strong is type n mortar?
Type N mortar has a compressive strength of about 750 PSI, which is ideal for use with semi-soft stone or masonry applications. It’s more elastic than a high strength mortar, which helps to prevent cracking and spalling of adjacent masonry units.
