Mortar Ratio For Brick Masonry: Focus On External Facades

mortar ratio for brick masonry

When constructing a new wall, or repainting an existing wall, the correct mortar ratio for brick masonry is extremely important. If you don’t get the mixture correct, you could be in for some serious problems down the line.

Mortar is used in construction to stick masonry units together, by filling in the gaps between bricks, stones, or concrete blocks. Primarily, this is to seal the masonry together, but can also be used for decorative purposes.

The importance of using the right mortar ratio for brick masonry lies in the strength of the overall finish of the wall. The correct mortar ratio for brick masonry will create a strong wall, be it load bearing or non-load bearing. The opposite is a wall that will quickly deteriorate, if it even bonded in the first instance.

What Types of Mortar for Brick Masonry Are There?

There are multiple different types of mortar mixes that are used for different purposes during construction. These are known as mortar type M, N, O, K, and S, and all have a different mortar ratio for brick masonry.

Some require more sand, or cement, whilst others require the inclusion of lime, which helps the wall to breathe. This is essential for certain types of wall, and for preventing moisture damage from occurring.

Some types of mortar are preferred for structural wall building, whilst others are designed primarily for repointing. This is where older mortar is replaced with new mortar to maintain the structural support of a building.

As mortar is designed to be weaker than the bricks used in masonry to allow for flexibility, repointing is a common maintenance job.

Ensuring the Correct Mortar Ratio

To ensure that you are using the correct mortar ratio for brick masonry, in your specific project, it’s essential to know which mortar mix you require.

It can be very beneficial to seek the assistance of a trusted expert, before moving on with your project, as well as fully understanding the procedure for mixing and applying mortar.

For general purpose masonry, mortar type N is commonly used. With a medium strength, the mixture normally consists of a mortar ratio for brick masonry of 6 parts of sand, 1 part of lime, and 1 part of cement.

The mix for mortar type N varies significantly from the much stronger, but more limited, M type mortar. This has a mix of 12 parts of sand, ½ part of lime, and 1 part of cement.

The Best Brick Masonry Protection

Once your mortar mix has set and is secure, the next step, and a very important one, is further protecting the exterior of the wall from damage. This includes damage from the weather, but also the build-up of dirt and grime that can detract from the finish of your wall.

One of the most popular and effective ways to do this is through the use of a professional wall coating. A wall coating is a substantial leap above your standard everyday masonry paint in terms of the vast range of benefits that it offers.
