Advice On Repairing Masonry Walls From Greengates Builders Merchants Accrington, Lancashire

Today here at Greengates Builders Merchants Accrington, Lancashire we are going to help you to repair masonry walls; which method to use and which materials you’ll need.

Mortar in a masonry wall can be damaged through natural weathering, chemical degradation and external bracket fixings. Now we are in spring/summer this is the perfect time to carry out any repairs necessary to your masonry walls.

Materials/ tools you will need:

1.          Jointing Tool

2.          Brush

3.          Castle Ready-to-use MORTAR Mix

4.          Pointing Trowel

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 applications. 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. Castle Ready-to-use Mortar Mix is formulated to produce good quality mortar quickly and easily. It is an ideal solution for a whole range of building, paving and repair jobs.

How 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.
