4 CEMENT RENDERING
The external façades of OPH are rendered and painted white, including the light courts. Maintenance of these
façades should follow key guidelines as set out below.
Permitted Actions
Regular inspections to check for looseness,
signs of dampness, cracks, bulges,
peeling, blistering and mildew.
Where the existing composition of the render is
known (including all components, colour, strength
etc), replacement of render may be commissioned
as part of a refurbishment / conservation project.
Notes / guidelines
Not Permitted Actions
Adhoc render repairs and replacement.
■■Replacement of render should only be undertaken where the existing render is badly
deteriorated and causing problems to the substrate (eg allowing water penetration).
■■Replacement render should never be stronger than the existing, or
than the substrate masonry to which it is applied.
■■The substrate and each consecutive coat should be pre-dampened before applying the next coat.
■■Work should not be carried out in excessively hot, dry, sunny, windy or cold conditions.
■■Works should only be undertaken by qualified tradespeople, experienced in working on heritage sites.
5 PAINTING
5.1 EXTERNAL PAINTING OF MASONRY
A paint finish has been applied to the render externally at OPH. The paint
finish should be maintained using the following guidelines.
Permitted Actions
Regular inspections of the paint finish to the external
facades of the building to identify any defects promptly.
The repainting of external façade and walls should
following the program set out in the Life Cycle
Cost Plan, to ensure those facades with greater
wear and tear or those with greater exposure (for
example the western facade, which receives the
brunt of the summer afternoon sun) are addressed
as a priority. A seven year cycle of repainting is
considered appropriate for the exterior of OPH.
Use of paint types to match as closely as possible
the existing finishes, except where the existing
paint finish is deemed to be inappropriate
and /or detrimental to the building.
Not Permitted Actions
Paint scrapes to determine an acceptable colour
match for any external repainting (refer to Building
Fabric Investigation Permitted Action Schedule).
