About Lime Mortar Brick Pointing

For those of you reading this blog post you might never look at the mortar between the bricks in your home. But, regular inspection of the structure that holds your home together is a worthwhile check, even if you just do this annually.

It is likely your pointing is porous and softer compared to cement based mortars used in modern buildings.

New Carden Roofing and Building only use traditional natural hydraulic lime mortar with the intention to patch, or repoint as well as repair cracked and decayed mortar joints. WHY? Because moisture is able to evaporate through mortar instead of the bricks or stones of the building. Using cement in repointing mixes causes damp issues, accelerated decay and sulphate attacks. Mortars that contain lime and sand are not susceptible to this damage.

New Carden Roofing and Building make sure whatever work they do that it would be more appropriate for long-term repairs. We use traditional raking out materials and tools with the intention to generate a perfect bed for the mortar that needs to be replaced.

The squad is trained in the use of hand tools for small or patch areas or gun injection lime mortar systems for larger areas of pointing. There may be times when the surface cleansing requires eliminating lime mortar deposits. In certain circumstances, cleaning with clean water and brushing the surface may be adequate to eliminate mortar deposits vigorously.

Another important piece of information we are giving you here is - Not to Use Cement Mortar on Victorian Houses.

Cement mortar has completely different characteristics to lime mortar. It is less porous and brittle and includes extra additives that can make it completely waterproof. The majority of the time, cement mortar is harder than even the bricks it holds together – so, when the ground moves below, the bricks press against the cement. Unsurprisingly, cement mortar is also cheaper to make and doesn’t require as much skill to mould. This is why we only ever use lime mortar on your property, as it is the only material that keeps your brickwork safe and looking wonderful.

The repointing style we choose will depend on the style and type of your property and the kind of brick it was built with.

The different styles of repointing are - Flush Pointing - Tuck Pointing - Penny Roll Pointing and Weather Struck Pointing.

How Long Does Lime Pointing Last?

Lime mortar that is reasonably sheltered can last for hundreds of years. But focusing on buildings in Scotland and those in exposed areas to the types of varied weathering conditions, could lead a to house needing to be repointed every 50years maybe. There are factors that could cause the lime mortar around your home to decay more quickly as over time, all kinds of mortars do deteriorate.

Lime mortars protect the masonry and stonework of the building by being the weakest link. Rather than the stonework being broken down by the harsh weather, the lime mortar is. This sacrificial relationship makes lime an amazing material.

Take into consideration where ordinary Portland cement mortar, commonly known as OPC mortar or just cement mortar isused, you will often find the face of bricks and stonework are blown off. This is because the stones and bricks are the weakest links, and therefore they will be broken down instead of the mortar.

And if you are still unsure how good the pointing work is around your home, give your local roofing and building company in Fife a call.
