Specification and comparisons

Using sample panels and benchmark rooms to agree quality

Words describe a finish imperfectly, and photographs on a screen do not show sheen or texture accurately. A sample panel — a section of wall, or on a larger job a whole benchmark room — gives everyone a physical reference to agree against before the rest of the contract is coated to match it.

What a sample panel is for

On a smaller job, a sample panel might be a single wall or door coated fully to the specified system, viewed in the actual light of the room. It confirms colour, sheen and coverage before the client commits the whole property to that same finish.

When a full benchmark room makes more sense

On larger contracts — a block of flats, a school, a hotel corridor run — coating one complete room or bay to the agreed standard gives a physical benchmark that snagging on every subsequent area can be measured against, rather than relying on memory or written description alone.

  • Used on repetitive spaces such as corridors, cells or identical flats
  • Coated fully, including trim and ceiling, not just the main wall
  • Kept accessible for reference throughout the rest of the contract

What should be checked at the panel or room stage

Colour and sheen are the obvious checks, but the panel should also confirm coverage, film evenness under the room's actual lighting, and any texture from application method. Approving a panel without checking all of these tends to surface disagreements later, once the whole job has been coated the same way.

  • Colour matched against the agreed reference, not just approved by eye
  • Sheen level checked under the room's normal lighting conditions
  • Coverage and evenness checked, not just the colour itself

Recording the approval formally

Once a panel or room is approved, it should be signed off in writing, dated, and ideally photographed, so it can be referred back to if a dispute arises later about whether the rest of the job matches what was agreed.

How we work on this

  • We coat sample panels to the full specified system, not a shortcut version
  • We view approved samples under the room's actual lighting before sign-off
  • We photograph and date approved panels for reference throughout the contract

Questions we are asked about this

Does a sample panel cost extra?

It typically forms part of the agreed programme rather than a separate charge, since it uses the same materials and system already specified for the job.

How long should I wait before approving a sample panel?

View it at more than one time of day if possible, since natural light changes how colour and sheen read, particularly in rooms with large windows.

What happens if the rest of the job does not match the approved panel?

The approved, signed-off panel becomes the reference point for any snagging discussion, which is exactly why recording it formally at the time matters.

Ask us to prepare a sample panel or benchmark room before committing to the full contract programme.

A physical, signed-off sample removes ambiguity that words and screen photographs cannot resolve.
