Repointing - the age-old problem
The basic problem with repointing is that very
few people actually enjoy doing it. It is so slow and
messy that there is very little pleasure or profit - in
it. So the natural temptation for the person doing it is
to try to find ways of doing it more quickly. Such as
not taking out enough of the old mortar. Or causing
havoc with the dust from raking it out. Or rushing the
pointing and leaving an untidy finish. Which means that,
without close supervision, the person paying for the
work is never really sure of its quality, or has to
spend time sorting out the chaos caused by the way the
work is done.
All too often what should have been
a simple job turns into a series of problems for all
concerned.
Gun-Point - The
quality repointing
service
At
Gun-point our approach is totally different.
We are
not caught in this vicious cycle of boredom,
inefficiency and skimping. Instead we have developed a
unique range of power tools to ensure a proper depth of
rake of the old mortar. Then we put the new mortar back
into the joint with our patented mortar pump and
gun. | All our teams are trained to use this equipment
accurately and carefully and repointing is their major
activity. We cater for
brick, rubble stone and ashlar properties as well as tunnels,
kerbstones and paving. We specialise in deep pointing and
overhead working and the raking and repointing of hard old
cement-based mortars.
And our experience in solving both
the technical and operational problems of repointing is
second-to-none.
The Gun-Point Mortar Pump and
Gun - Powered Mortar Injection
At the heart of our service is the
patented Gun-point mortar pump and gun. This low pressure high
volume machine is light enough to go up scaffolding and small
enough to go down tunnels. its powerful electric motor can
pump any standard mortar mix. As well as traditional lime
mortars, the gun-pont machine accommodates all types and
grades of gauged, masonry and cement mortars. we like to use
local sands that match the colour and character of the
original finish, but any colourants and other admixtures may
be added to the mix as required.

Raking - The key to a good
'key'
Everyone knows that the most critical part of
repointing is to remove enough of the old mortar. But it
is tiring, dirty and few do it properly.
No-one else has our range of raking tools. Unless
repointing was a full time activity they would be too
expensive.
At Gun-point we see them as vitally
important. Our basic tools have integrated dust guards
with adjustable plates that once set will ensure an even
depth of rake.
| The guard are linked
to our own speciall-design dust extraction units which save
the property and the operative from the mess and inconvenience
usually associated with raking out.There is thus little
disturbance to residents and other workers on-site.
And
because our teams are all full-time, they know how to use
these tools with the minimum possible damage to the face. We
aim to follow the recommendations of the British Standard 8221
(that is normally a rake 50% deeper than the width of the
joint) - but any depth can be specified and - more
importantly,
maintained.
At Gun-Point we offer a full range of mortar
colours and finishes to suit the requirements of the project
and complement the aesthetics of the original construction
materials.
