What is repointing?
Repointing is the process of renewing the pointing (the external part of mortar joints) between the brickwork or flint work . Weathering and decay cause voids in the joints between masonry units, allowing the undesirable entrance of water.
It is essential that the mortar used for repointing have similar performance characteristics to the original mortar used in a building. Coastal Wall Ties can take samples of the mortar to ensure that the correct sand and binder are used, this is to ensure that the repointing is matched as close to the original mortar as possible.
Types of Pointing
There are several types of pointing finishes available these are:
- Flush– A nice flat finish to the face of the brickwork (generally seen on old lime mortar properties)
- Bucket Handle (compressed rubbed finish) A concave finish used on properties since about the 1950’s
- Recessed– This is a flat finish but recessed by 3mm from the face of the brick.
- Weather struck – A popular style that is slightly angled and cut on the brick edge.
- Birds beak – A popular style on flint work that is angled on both sides to create a birds beak point in the centre of the joint.
- Tuck pointing – A victorian style of pointing that hides large and uneven brick edges. The mortar joints are coloured to match the brickwork and then a lime putty ribbon is skilfully applied to create a perfect, straight narrow joint.
The Pointing Process
The first part of the re-pointing process is to remove the old mortar by a minimum of 20mm, ensuring all mortar is removed to the top and bottom of the joint, this is done using 5″ angle grinders equipped with diamond mortar raking blades and dust extraction hoovers. In some cases power tools are not permitted and the use of hand tools such as comb hammers will be used.
The walls are then washed down to remove all loose dust from the joints in preparation for pointing.
When creating the mortar it is extremely important to match as closely as possible to the existing, not only for the colour but for the strength and permeability factors too. If a hard mortar is used on soft bricks the bricks will degrade faster and cost a large amount of money to put right.
When applying the mortar we use a traditional hawk and trowel, this enables us to force the new mortar into the joint ensuring their are no voids, then the mortar is shaped to the required finish.
This is a skilled operation and our staff are fully trained to extremely high standards.
