Permitted Actions
Paint sampling of all heritage fabric provided that
damage caused to the heritage fabric being analysed is:
■■no greater than practically required for
undertaking the technique; and
■■discretely located or obscured from public view.
Repositioning of movable furniture or other
portable items to enable access for paint sampling
provided it is carried out in accordance with the

Use of any tools/equipment enabling access to heritage
fabric for the purposes of paint sampling provided
that all heritage surfaces such as floors and walls
are adequately protected from potential damage.
Not Permitted Actions
Paint sampling of heritage fabric where the damage
caused to the heritage fabric being analysed
is excessively large will require specialised
repairs and is clearly visible to public.
Repositioning of movable furniture or
other portable items to enable access for
paint sampling without reference to the
Housekeeping Permitted Action Schedule or prior
consultation with the OPH Heritage staff.
Use of any tools/equipment providing access to heritage

6.3.2 MORTAR AND PLASTER ANALYSIS
Mortar and plaster analysis is a scientific method for establishing the composition of mortar and plaster.
The process involves the collection of small samples of mortar or plaster which are then tested under laboratory
conditions to establish what materials and how much of each has been used to produce the existing sample.
The use of mortar and plaster analysis is appropriate for:
■■matching new mortar or plaster to existing heritage built fabric.
Advantages — Analysis of existing mortar and plaster samples ensures that the finished appearance and
strength of new materials integrates successfully with existing materials
Disadvantages — Sampling involves destruction of original built fabric; the findings of the analysis may identify
components that are no longer readily available
