Preparation and decoration have separate scopes
Board joints, screws and corners require treatment compatible with the system. The chosen decorative finish follows. The quotation should say whether painting, primer, cladding or substrate preparation is included, and identify who will complete each stage.
What Q1 to Q4 help describe
The levels describe surface preparation: basic Q1, standard Q2, more demanding Q3 and extensive preparation for high-quality Q4 finishes. Choose in relation to the planned decoration and lighting; the level is not a classification of board strength.
Plan lighting before finishing
An LED strip beside a wall or a side window can make small variations more noticeable. Show the position of each light and the effect you want. Agreeing lighting and decoration early helps determine suitable surface preparation and how the completed result will be reviewed.
Junctions, corners and different materials
Connections to joinery, other finishes and existing elements need their own details. Not every junction can be treated like a joint between two boards. Review movements, interruptions and access panels, together with the way the finish should remain consistent with the design.
Preparing for the next stage
Review surfaces and the conditions required by the selected products before decoration. Preparation and drying follow their instructions. Coordinate this stage with the decorator or cladding installer; proceeding before a stage is ready can lead to repeated work.
Details to include in the quotation
Ask for the agreed level, surfaces, special junctions and intended decoration to be recorded. Explain where grazing light or prominent surfaces are planned. Keep this information with the quotation so that the expected finish has a clear scope for review on completion.
