Protecting your stones from wear and to reduce mortar decay is vital for the long life and beauty of your stonework. Over time, weathering takes its toll on your stonemasonry and you will need to make repairs more often.
The four major causes of stone wear and tear are:
- Water penetration
- Crystallisation of soluble salts
Your stonework’s structure is the main piece in making sure you protect your stones from decay. Allowing for a strong structure using mortar, like Lithomex, improves your stones ability to defy decay.
The issue with natural weathering
Over the course of a decade, your stones will go through many cycles of wetting and drying. During these cycles, the weather will chip away at your stones and pointings’ integrity.
You will see your mortar crack and crumble allowing stones to shift. The stones may move and fall; the stones will damage.
After 10 years of cycles, especially if the air is damper and more cold than usual, your stones and mortar will be decaying faster.
Reduce mortar decay
You can help your stonework and save yourself from expensive repair bills by seeing the problems earlier on. This way, you can uphold your mortars’ strength and lessen the expense.
You need to see if your mortar is:
- Falling out
- Missing (gaps)
If you are seeing any of these happening, now is the time to take action before your stones start shifting and falling. This way, you can prevent having to replace and repair stones unnecessarily and reduce mortar decay in your walls.
One approach to reduce mortar decay is to provide some protection for your walls from the elements. This may mean creating structures or adding trees and hedges to negate the effects of wind and rain; used like a barrier.
But if you are seeing any mortar issues occurring now, you can have your stones re-pointed using a lime-based mortar. This will keep your structures stronger for many extra years and protect your valuable stones for longer.
