Pointing Tools

The term pointing describes the physical act of applying lime mortar into the joints of brick or stonework. Repointing, on the other hand, is a term used to describe repairing or replacing an existing mortar in the joints. Repointing often requires the removal of any damaged lime mortar or rigid cement mortar with a hand tool, such as a sharp chisel, before new lime mortar is applied.

A broad range of tools can be used for repointing, and which is most appropriate to use can vary depending on the joint size and whether you are repointing stone or brick. In our opinion, the most versatile tool is the trowel end and square small tool, which works well for small to medium masonry units and typically comes in a range of sizes to best suit the joint. However, other tools can assist with making the job easier. A brick joiner is an excellent option for pointing brickwork, as its larger size allows for quicker mortar application into the joint without losing precision. If repointing stonework with larger joints, a tongue trowel is handy; its larger size and shape help distribute the mortar more evenly, speeding up finishing time. For holding the mortar while you point, a plasterer’s hawk or large trowel can be used. Lastly, to finish the joints, we recommend using a churn brush.

A churn brush is our recommended tool for pointing, which provides several benefits when finishing a lime mortar in the joints. First, the churn brush compacts the mortar into the joint, closing any initial shrinkage, improving contact between the mortar and the masonry, and tidying up any mortar on the edges. Second, the churn brush leaves a textured surface in the mortar, which increases the surface area and allows for improved evaporation from the joint as it opens the surface.

Using power tools, such as angle grinders or drills, to remove an existing mortar can be risky, as this can damage the existing stone masonry or brickwork. We always advise using hand tools, like a hammer and chisel, as this allows for greater control and precision. However, there may be occasions, such as removing hard cement mortars, where power tools are necessary. If so, proceed carefully to mitigate unnecessary damage to the masonry units.
