How RAL 7033 reads
Cement grey is a mid grey with a clear green cast, greener than RAL 7023 concrete grey. It reads like damp cement and works well beside planting.
Where it turns up
It suits machinery, render, garden buildings and fences. Matt or satin keeps it natural; hold the sample against nearby stone or concrete, as the green cast shows most by comparison.
Ordering RAL 7033 in paint or powder
Quote the number, not just the name: say "RAL Classic 7033" and add the gloss level, the product type (wall paint, metal paint, powder, aerosol) and the surface. The same number mixed by two makers, or in two gloss levels, can look slightly different, so keep a whole job in one batch and look at a sample in daylight first. The paint counter guide covers the questions to ask.
