Repointing your wall goes beyond aesthetics. Removing healthy mortar from a stone wall can result in unnecessary damage.

Choosing the perfect color can make all the difference. Imagine spending hours repointing your wall, only to realize that the color is completely wrong. That’s why it’s crucial to do a color test on the actual wall beforehand. Don’t rely on a different surface because the humidity in the stone can affect the final color. And let’s not forget the impact of the sand color, which can dramatically alter the overall look. Aim for a mix of 2 parts smooth sand to 1 part coarse sand for the ideal result. It’s always better to test first and avoid any costly mistakes. If you’re looking for convenience, you can purchase pre-colored lime mortar, although it can be quite pricey.

How to Properly Point Stone Walls

Stone walls have a long history and should be treated with care. Lime mortar is the traditional material used to build stone walls, as it allows the walls to breathe, move, and expel excess water. Unlike cement, which can cause damage, lime and sand provide the necessary flexibility. Follow our step-by-step guide and video to learn how to prepare and point your stone walls correctly. From removing old render to brushing off excess mortar, we’ll show you all the tips and tricks for a perfect finish. Don’t forget, always work from top to bottom and do a color test before starting the entire wall.

Can I Repoint a Wall Myself?

Is Mortar or Concrete Better for Stone Walls?

Concrete should never be used on stone walls because it is too rigid and doesn’t allow for proper water evaporation, leading to dampness and potential damage to the wall. When repointing stone walls, it is best to opt for lime mortar instead, as it provides flexibility and allows for natural moisture regulation.

Can You Repoint Over Old Mortar?
If your existing mortar is in good condition, there’s no need to go through the trouble of repointing it. However, if you happen to notice any damaged or cracked mortar, it’s crucial to remove it completely. This will create a depth of approximately 2cm, allowing the new lime mortar to form a strong bond. Remember to also remove any traces of cement from the old mortar for optimal results.
What time of year is best for repointing?
The best time of year to repoint your stone walls is either spring or autumn. Winter is too cold, and the lime mortar is unable to dry sufficiently, leaving the walls damp. On the other hand, summer can be too hot, which can cause the mortar to dry too quickly and potentially result in cracks. By choosing spring or autumn, you allow the lime mortar to dry naturally and evenly, ensuring a strong and durable finish for your stone walls.
