A historic paint analyst is a conservation scientist who examines paint layers in historic buildings to reveal original and subsequent decorative schemes. Using microscopy and elemental analysis techniques, they identify the pigments, binders and application methods used in each layer, allowing the sequence of redecoration to be established and original colours to be matched. This service is increasingly required for the restoration of significant listed building interiors, country houses and public buildings, and is carried out by specialists with training in both conservation science and building history.
What they do
- Take paint samples from walls, woodwork and ceilings at strategic locations
- Prepare cross-sections and examine paint stratigraphy under microscope
- Carry out elemental analysis (XRF, SEM-EDX) to identify pigments
- Identify historic binders including limewash, distemper and oil paint
- Sequence the decorative history of rooms and buildings
- Produce analysis reports with colour recommendations
- Advise on conservation paint suppliers and historic colour matching
- Provide specifications for reinstatement of original decorative schemes
When you need one
A historic paint analyst is needed before redecorating significant historic interiors, as part of conservation management plans, or when planning conditions require evidence of original decoration.
Typical costs (UK, 2025)
| Job type | Typical cost |
|---|---|
| Paint analysis - cross-section microscopy (per room) | £600 - £1,500 |
| Full building decorative scheme analysis | £2,000 - £6,000+ |
| Analysis report and colour recommendations | £400 - £900 |
| Conservation advice and specification | £300 - £700 |
| Hourly rate | £70 - £120 / hr |
The number of samples and rooms required depends on the scope of the project. For a significant interior restoration, a full building analysis covering multiple rooms and surfaces will be needed before specification can begin.
Qualifications to look for
ICON membership or accreditation (ACR - Accredited Conservator-Restorer) demonstrates professional standards in conservation science. Many historic paint analysts hold ICON membership, particularly those with a background in decorative arts conservation. Check membership at icon.org.uk.
Historic England publishes guidance on paint analysis methods and endorses practitioners who work to current best practice standards. Specialists should be familiar with Historic England's guidance on the analysis of historic paint layers.
How to find a historic paint analyst
Frequently asked questions
How is historic paint analysed?
Samples are taken from stratified paint layers, embedded in resin, cross-sectioned and examined under microscope. Elemental analysis (XRF or SEM-EDX) identifies pigments and binders. The results reveal the sequence of decoration from the earliest layers to the most recent, allowing each phase to be dated approximately. The analyst produces a report identifying the original and subsequent colour schemes.
Do I need paint analysis for a listed building?
Not always, but planning authorities and Historic England increasingly require evidence of original decorative schemes before authorising reinstatement of historic interiors. Paint analysis can also reveal phases of building history not apparent from the structure alone. For significant interiors, analysis is considered best practice before any repainting.
Can paint analysis recreate exact historic colours?
Analysis identifies the pigments and mixing ratios of historic paints but recreating an exact match requires expertise - pigments have changed in formulation and historic binders (lead, chalk, limewash) behave differently from modern paints. Specialist conservation paint suppliers can produce matched colours using traditional pigments and binders. The analyst's report provides the specification for the paint supplier.
