The Colour Beneath the Coat: A Finish Record for Somerset Repair Work

In repair work, the most difficult question is often not structural. It is the quieter one asked months or years later: what was this finished with? A door that has weathered unevenly, a patch of lime plaster that has taken colour differently from its neighbour, or a skirting board that needs a small local repair can all turn on a product name, a batch number or the number of coats applied. Without a record, the answer becomes guesswork.

A finish archive is a modest response to that problem. It need not be a laboratory or a digital system beyond the means of a small workshop. It is a drawer, a folder and a habit: a labelled collection of cured samples, product notes and batch references kept for each client job. For Somerset trades working on older buildings, where finishes are often bespoke and records are frequently absent, that habit has considerable value.

Why a finish record earns its keep

Repair work is cumulative. A workshop may be called back to the same house in five years, or a different firm may be asked to match work carried out by a predecessor. In both cases, a finish record shortens the conversation. It allows a maker to say not simply that the colour was green, but that it was a particular distemper over a particular plaster, applied in two coats after a specified primer.

Heritage work makes the point sharply. Limewash, distemper, linseed oil paint, wax polish and traditional stains all behave differently from modern equivalents. Colour can shift with substrate, porosity and drying conditions. A sample on a piece of plastic is not the same as a sample on oak, stone or plaster. Keeping the right kind of sample, alongside the product details, gives future repairs a fair chance of matching both appearance and performance.

There is also a commercial benefit. Clear records reduce the time spent re-establishing what was done. They support maintenance schedules and give clients confidence that the workshop treats its work as a long-term relationship rather than a single transaction.

What to keep

A useful archive holds evidence, not clutter. For each job, the following should be sufficient in most cases:

• A cured sample on the correct substrate, or on an inert board where the substrate cannot be spared. A brush-out alone is rarely enough.
• The manufacturer, product name, colour code or recipe, sheen level, dilution and number of coats.
• The supplier and batch number, with the purchase date where available.
• A short application note covering preparation, primer, temperature, humidity and method.
• A photograph taken in daylight, with a scale or recognisable reference point.
• A note of where the sample is stored and when a copy was given to the client.

For heritage repairs, add mortar mix, plaster specification, stain recipe or paint-layer notes as appropriate. Where a listed building or conservation area is involved, record any consent or specification reference that governed the work.

A label that survives the drawer

A sample without a label is merely an object. The label should carry a unique job reference, the location within the property, the date and the product or mix. Write it on the sample itself where possible, using a pencil or archival pen, and repeat it on the bag or box. Keep the digital index in the same order as the physical drawer so that one can be checked against the other.

Storage matters. Samples should be kept flat, dry and out of direct light. Solvent-based products and oils should be treated with the usual care. Client samples should not be mixed together, and old samples should be reviewed when a product formulation changes. An archive is a record of what was used, not a guarantee that the same product remains available.

The client copy

At practical completion, give the client a one-page finish schedule and, where sensible, a small cured sample. Explain how to store it and note that it is a reference rather than a warranty. For landlords, agents and facilities managers, this is often welcomed because it supports future maintenance. For householders, it is a simple courtesy that makes later repairs less anxious.

A training aid on the bench

An apprentice can learn a great deal from a well-kept finish archive. Comparing sheens, identifying substrates and seeing how batch variation affects colour are lessons that no catalogue can teach. A short monthly review of recent samples, perhaps at the bench before the day starts, keeps the archive alive rather than static.

A modest template

A single page per job is enough. Record the job reference, client and address; the date and element treated; the substrate; the product, manufacturer, code and batch; sheen, dilution and coats; preparation and site conditions; the applicator; the supplier; photograph references; the sample location; the date a client copy was issued; and any planned revisit. The page need not be elaborate. It need only be completed.

Limits and care

A finish archive does not replace testing. Where a finish is being extended or repaired, a small trial area remains essential. Old products may have changed formulation, and some historic finishes carry health and safety considerations that require proper assessment. The record is a starting point for informed work, not a substitute for judgement.

In Somerset, many of the buildings we repair will outlast the hands that first finished them. A labelled sample and a written note are a practical form of handover. They allow the next person to begin with knowledge rather than assumption, and that is a trade courtesy worth keeping.
