Maintaining Pointing Mortar for Longevity

When you’ve taken the time to point your brick slips perfectly, the last thing you want is for the mortar to lose its look or strength too soon. That’s where lime based mortar really shines especially when it’s our gun-injected mortar, designed for an even, professional finish every time.

Think of it like looking after a new car. You can buy the best model available, but without proper care, even the finest engine starts to lose its edge. The same goes for mortar quality matters from the start, but maintenance keeps it looking great for years.

In this guide, we’ll walk you through everything you need to know about maintaining your pointing mortar, from choosing the right product, to application tips, to keeping it protected over time.

1. Why Choose Lime Based Mortar?

If you’ve ever seen brickwork that seems to ‘breathe’ with life retaining colour, resisting cracks, and looking just as good decades later there’s a good chance lime based mortar was involved.

Unlike standard cement mixes, lime based mortar is more flexible and less prone to shrinkage. That means it moves naturally with your brickwork, reducing the risk of cracking. It also allows moisture to evaporate rather than trapping it, helping to protect your brick slips and the surface beneath.

In short, lime based mortar isn’t just a filler it’s a breathable, adaptable bond that works with your wall, not against it.

2. Understanding Our Gun-Injected Mortar

3. Preparing Your Mortar for Application

Before you start, preparation is key. The better you set up, the smoother the process will be.

1. Clean the Joints – Remove dust, loose material, or old mortar.

2. Mix Correctly – Follow the instructions for the right consistency; it should be smooth but not watery.

3. Load Your Pointing Gun – Fill evenly to avoid air gaps.

Think of it like baking — rushing the prep stage means your end result may look fine at first, but won’t hold up over time.

4. Application Tips for a Flawless Finish

Here’s how to get the most from your lime based mortar:

• Work in Manageable Sections – Don’t try to tackle the whole wall at once.

• Consistent Pressure – Apply steady pressure on the pointing gun to avoid uneven joints.

• Compact the Joints – Gently press mortar into the joint to remove voids.

• Finish Smoothly – Tool the joint for a neat finish while the mortar is still fresh.

A little patience here pays off massively — well-packed joints are stronger, look better, and last longer.

5. How to Maintain Your Pointing Mortar

Good news — lime based mortar is naturally long-lasting. But with a little attention, you can keep it looking fresh for even longer.

• Regular Inspections – Check for cracks or gaps once or twice a year.

• Gentle Cleaning – Avoid harsh chemicals; a soft brush and mild soapy water are usually enough.

• Protect from Water Damage – Ensure drainage is good and avoid constant water exposure.

• Avoid Salt Build-Up – If you spot white deposits (efflorescence), brush them away gently before they harden.

Think of it as routine servicing for your wall — a quick check now and then can prevent costly repairs later.

6. Common Mistakes to Avoid

Even the best mortar can underperform if it’s not used or maintained properly. Here are the main pitfalls:

• Skipping Joint Cleaning – Mortar won’t bond properly to dusty or loose surfaces.

• Over-Watering the Mix – Too much water weakens the final set.

• Rushing in Cold or Wet Conditions – This can slow curing and affect strength.

• Neglecting Aftercare – Leaving mortar exposed to frost or heavy rain in the first days can cause surface damage.

Avoiding these mistakes will keep your pointing mortar looking sharp for years.
