I am assuming that there are patches of plaster missing from the walls
as a result of removing the old cupbaord. If it is small areas of
missing plaster then you could get away with maybe using carlite
bonding and finishing with finis plaster. If you use this two oat
method then the bonding coat will have to be a couple of mm below the
existing plaster so there is room enough to put the finish coat to the
same level as the existing plaster. There is also a one coat plaster
available from wickes which would be fished in one go to the same line
as the plaster.
If it is one whole area above 5 or 6 ft square then plasterbaord stuck
with a plasterboard adhesive which would have to have any gaps filled
then possible to paint over. Cutting a hole in the plasterboard for
the programmer is not a good idea. The programmer/ or whatever it is
should be placed on the new surface in order to look unbodged. To box
inthe pipes you can use 2x1 or 2x2 timber. One length nailed/ screwed
to each wall. U can use 6mm thickness of plywood (as a minimum). This
would be offered upto the wall and if it shows large visible gaps it
would have to be scribed to the wall. If the gaps are not too bad then
you could filler the gaps later.The width of the plywood would extend
beyond the pipes which can be measured and the plywood cut to size.
What I do is then batten the back of that panel, top, bottom and side.
This provides the fixing for the other panel. *Note this is to avoid
making a frame for the boxing in.*
The other panel, once measured . can be screwed to the batten ( which
is on the back of the other panel. You will have to screw it cos it
might not be strong enough to take a knocking from a hammer.When it
comes together it is strong enough to hold its own shape.
For the boxing in u are essentially building the frame onto the back
of the panels making it easier. Usually a box frame is made up and the
ply nailed or screwed to it. The thicker the panel the more ridged the
structure.
