Paint Info

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.
