Repointing Process

The most critical part of repointing is to remove enough of the old mortar.

But it is tiring, dirty and few do it properly. A qualified tradesman at Advanced Repointing would take out 20 -25 millimetres of the mortar joint with a grinder connected to a vacuum extraction system to eliminate excess dust.

Then with a motorized injecting mortar gun, a specifically formulated mortar to suit your building would be injected back into the joints. The right mortar for your job will be suggested by one of our team of professionals on inspection based on age, style and damage.

A lime base mortar is most commonly used as it re-absorbs the carbon dioxide and is a softer substance which puts less strain on the building. Most mortars used in repointing will consist of sand, lime or cement, and water. Weather and the time of year can also be factors in the type of mortar used. Colour of the mortar is also vital and this is controlled by the type of aggregates or oxide.

All areas must be filled so that no pockets of air remain in the joints. This helps to prevent failure in the mortar and future erosion. All work is then cleaned with light acid and high pressure cleaning
