Introduction...
Brickwork too suffers from the effects of successive harsh winters. Our homes can become rather tired looking and frayed; but with a few basic tools and materials we can not only spruce up considerably the appearance of our homes but stop further erosion of the brickwork structure and the increased likelihood of damp ingress and subsequent damage to internal walls. There are three popular styles of pointing – flush, concave and weathered pointing. We shall first look at the differences between the three then work step by step through the process of repair.
- Flush pointing, is where the mortar between the brickwork is flush with the surface of the brick. To achieve this finish allow the applied mortar to almost dry and then rub between the joints with a piece of wadded sacking, or other coarse material.
- If a slightly concave appearance to our pointing is desired; then smooth out along the joints with a short length of bent copper tubing Brush lightly to avoid removing excessive mortar.
- Weathered pointing, the most popular style of pointing, has a formed slope to the mortar to allow better water run-off.
Preparation. Before re-pointing can be carried out we must prepare the brickwork. First, dig and rake out any loose and crumbling mortar between the bricks; this is best achieved using a cold chisel or bolster and a club hammer. Dig the joints out to a depth of about 1cm- and brush out any loose bits and dust from the crevice.

Once the gap has been cleaned out and is ready to be filled with mortar it will require a thorough dampening, but not saturation, by brushing with clean water. This will prevent the water from the mortar mix being absorbed by the surrounding brickwork too quickly. Do not completely soak the crevice as this retards the bonding and drying process.

Mortar Mixes. These now come ready mixed, to suit a variety of applications, and in a range of convenient size of packaging. Add water carefully until a fairly stiff consistency is achieved – and using a trowel – squeeze the mix into the prepared and cleaned out joint.

Mortar MixesWhere a weathered finish is required simply place and hold firmly a straight length of timber, or a straight-edge, below the horizontal joint, and use this as a guide for the angled trowel as you press and draw the mortar along the joint.
When the mortar is almost dried out and is hardening up, brush the brickwork surface and new pointing with a fairly stiff broom or brush.

Always keep safety in mind when working around the home and garden. By taking simple precautions we can avoid unnecessary injury. Wear safety spectacles as flying chips of mortar and dust can easily damage eyes, wear gloves and where excessive dust is generated, wear a dust mask. When working at height always ensure adequate and safe equipment is used.
