Repointing is needed in places where
the mortar joints have become soft or the mortar itself is cracked
or damaged. The damaged mortar is removed carefully, using a chisel
and hammer, so as not to disturb the surrounding brick
masonry. Fresh mortar is applied in layers. When repointing, the
depth of the new mortar should be twice the width of the mortar joint.
Mortar applied directly to the damaged surface will not hold up. Owners
of older homes will want to make sure that the fresh mortar matches
the original, therefore colour mixtures may have to be included in
the fresh mortar. |
