Brand · Product Line

Benjamin Moore / Aura Interior (for richer color depth in deep tones)

Recommended Finishes

Matte (walls) · Pearl (trim) · Satin (doors)

Deep colors look best in matte — gloss exaggerates surface flaws. Reserve subtle sheen for trim, doors, and high-touch areas.

Best Surfaces

Accent walls · Doors · Cabinetry · Built-ins

Coverage & Dry Time

Typical coverage 350-400 sq ft per gallon over a primed surface.

Touch-dry in ~1 hour. Recoat after 4 hours. Full cure 7-14 days.

Primer

Tinted primer in a similar value is highly recommended — saves a coat and prevents the wall colour from washing the surface.

Application Tip

Use a 9" microfiber roller on walls and a 2.5" angled sash brush for trim cuts. Two coats minimum for even depth.

You'll need

4.0 litres

1.06 US gallons · room for one touch-up coat. Buy slightly more to ensure single-batch match.

What is a RAL color?

RAL is the European color-matching standard used to specify exact colors for paints and coatings. Each code — like RAL 240 20 15 from the RAL Design System — maps to one defined color, so a manufacturer or painter anywhere produces the identical result. It's used first and foremost on window frames, doors, façades, gates, railings and powder-coated metalwork.
