Limelite Heritage Pointing Mortar
Limelite Heritage Lime Pointing Mortar is used for repointing brick and stone work, but mainly use for brick slip applications. The enhanced flexibility of Limelite Heritage Lime Pointing Mortar means that it can be applied with bagged or gun injection.
- Lime based, Portland cement free
- Long term durability and flexibility
- Easy to use, just add water
- Masonry walls built with Limelite Heritage Lime Pointing Mortar have improved breathability – increasing the resistance to frost and damp
- Designed to provide improved workability when repointing masonry joints
- Lime based mortars are less susceptible to sulphate attack
- The flexible nature of Limelite Heritage Lime Pointing Mortar means that a reduced amount of vertical movement joints are required and this reduces the chance of cracking
- Factory supplied and quality controlled
- Suitable for use in listed and heritage buildings
- Environmentally friendly - Lime mortars actively absorb CO2 from the atmosphere
Limelite Heritage Lime Pointing Mortar is a cement free blend of natural hydraulic lime and selected aggregates with additives designed to improve the workability of the mortar when repointing. Available in 6 colours with a strength class of M5.0.
Limelite Heritage Pointing Mortar is available in 0-2mm aggregate size for brick slips.
Range of colours
Limelite Heritage Lime Mortar is available in six standard colours. A colour matching service is available allowing us to match samples from our client’s site.
Lime mortars are vapour permeable - allowing moisture to evaporate and buildings breathe. This significantly reduces the risk of trapped moisture, damage to building fabric and mould growth. Eliminating trapped moisture in brickwork reduces the risk of frost damage and significantly improves thermal efficiency.
The flexibility of Lime mortars significantly reduce the risk of cracking and allow for slight movement and thermal expansion throughout the life of the building.
Reduces the need for movement joints
Cement mortars are brittle and typically require a significant amount of movement joints. Lime is far less susceptible to this and requires less than half the amount of joints that cement mortar requires.
Easy to Use
Limelite Heritage Lime Mortars are easy to use, just add water and mix.
Lime is produced at a far lower temperature than cement, therefore requiring significantly less energy to produce. Lime has a unique ability to absorb carbon dioxide from the atmosphere, further minimising the total CO2 emissions.
All of our products are manufactured in the UK and certified under BES 6001 Responsible sourcing. Tarmac was the first company within the cement and lime sectors to be awarded the BES6001 ‘Excellent’ rating across its entire product range.

Limelite Heritage Lime Pointing Mortars should be mixed using cool, clean water. Limelite Heritage Lime Pointing Mortars can be mixed using a conventional Belle type mixer. The inside of the mixer should be wetted and then the contents of the Limelite Heritage Lime Pointing Mortar bag should be emptied into the mixer whilst stationary. Approximately 5 litres of water will be required for each 25 kg bag of Limelite Heritage Lime Pointing Mortar.
A small amount of the water should be added to the dry powder and the mixer should be turned on. The water should be allowed to thoroughly disperse into the mix before adding more water. Continue adding small amounts of water until 4.5 litres has been added allowing the thorough dispersion after each addition. Allow the mortar to mix for between 5 to 10 minutes and then add the remaining water to achieve the required consistency. Slightly more or less water may be required and the consistency can be checked by placing a small amount of mortar on to the back of a trowel tapping it gently and allowing the mortar to spread evenly across the face, then hold the trowel upside down at which point the mortar should remain stuck. The workability of the mortar can be improved by allowing it to stand and then remixing it just before use.
Clean Up & Spillages Dry powders should be swept up and disposed of in accordance with Local Authority regulations.
Tools and equipment can easily be cleaned using water. Cleaning of tools and equipment should be carried out as soon as possible after application.
