Architectural Finishes Research (kleuronderzoek)
Architectural Finishes Research (AFR) is the study of historic surface layers — such as paint, varnish, gilding, or wallpaper — within architectural spaces. It helps reveal original color schemes, hidden decorative phases, and material histories, supporting informed decisions during conservation, restoration, or renovation.
What AFR Typically Involves
-
Visual inspection & documentation
-
Extraction of paint samples from selected areas
-
Cross-section preparation & microscopy
-
Embedding and polishing samples to reveal stratigraphy under visible and UV light
-
Pigment & binder identification
-
Using analytical tools to identify materials
-
Interpretation & historical contextualisation
-
Dating layers, comparing to historical records, and aligning findings with architectural or social history
-
Reporting
-
Clear, illustrated documentation for stakeholders (including Type 3/Type 4 reports in Dutch standards)

Types of AFR
-
Exploratory / Preliminary Research
Basic investigation to guide design or decision-making -
Type 3 Report
Focused on the documentation of existing layers, with interpretation and recommendations -
Type 4 Report
In-depth interpretation and reconstruction of decorative schemes, often supporting restoration or reinstatement of historical appearances -
Conservation-Integrated AFR
AFR conducted as part of ongoing conservation treatment (e.g., wall paintings, polychrome wood, gilded architectural elements)

Typical Questions AFR Helps Answer
AFR helps answer questions like:
-
What was the original colour scheme of this room?
-
Were there any hidden decorative layers beneath the visible paint?
-
Can we date the alterations in this space?
-
What materials and techniques were historically used?
