thing to remember when doing this is to always cut up from the bottom first, to
form the 'curf cut' and then cut down from the top, to prevent the brick tearing.
All prepared original and replacement works were then re-laid using lime
putty:silver sand mortar. The dusted and dampened prepared pockets to
receive individual ashlared bricks were then given a backing of this mortar
so that as the brick was carefully positioned it was fully bedded. To do this,
and ensure solid bedding, the back arrises of each of the ashlared bricks were
chamfered so the mortar could easily slide around the back and the brick.
With each brick supported on the laying trowel they were carefully slid in until
the brick was back flush and level with the surrounding brickwork (Fig. 116).

second floor platt band.
Other areas of the Platt band required pointing, which is not an easy thing
to do on tightly jointed gauged work if you have not been taught properly. We
would first clean out all the debris from the old joints back to a solid and clean
base. The mortar is then prepared from lime putty and silver sand to a consist-
ency of glazier's putty as used for tuck pointing. Once the brickwork is pre-
pared this putty is placed on the back of a feather-edge positioned to the joint
and using the appropriately sized jointer is lifted off and placed into the joint
until flush; any excess being neatly trimmed with the knife or 'frenchman'.
Once all the joints have been filled it is firmed up with the jointer and lightly
brushed clean. It was important to keep spraying this work intermittently with
