Do You Know How To Repair Masonry Walls?
Today we’ll be looking at how to repair masonry walls, which method to use and which materials you’ll need to carry out the job.
The mortar in a masonry wall can be damaged through freeze-thaw attack, natural weathering, chemical degradation and external bracket fixings.
To repoint large and small areas of masonry:
- Remove existing mortar with a jointing tool to a depth of about 15- 20mm, so that the new mortar contacts enough brick area to form a good bond.
- Obtain a clean surface by brushing out the joints to remove loose mortar or sand.
- Dampen down bricks and mortar joints to control excessive suction.
- Apply the mortar firmly into the joint.
- Repoint the head joints first and the bed joints second. This allows unbroken horizontal strokes to form straight, even bed joints.
- Shape all vertical joints first.
- Finish with the horizontal pointing.
- Leave the mortar to harden then brush off debris cleanly from the face of the brickwork.
The mix required for this type of repair is Ready to use Mortar Mix which is the equivalent of 1:1:6 (cement: lime: sand by volume), ready to use blend and provides a weather-resistant and durable mix suitable for most application. It can also be used to bed in replacement bricks. Castle Ready-to-use Mortar Mix is the cement recommended for this type of repair.
