Farrow & Ball 2.5L Flat Eggshell Bible Black No.225

Evoking the "starless and bible-black" night from the opening passage of Dylan Thomas' Under Milk Wood, this red-based black is a rich and intriguing tone for interior and exterior surfaces alike. In full daylight, it appears more violet, making for an unusual and luxurious front door colour.

Preparation: prime with the right Farrow & Ball primer first: Wood Primer & Undercoat for interior woodwork, Metal Primer & Undercoat for metal, and Masonry & Plaster Stabilising Primer for interior concrete floors and unsound masonry.

Dry in 2 hours and recoat after 4 hours; allow longer in cool or humid conditions, and note that some darker colours take up to 14 days to reach full hardness.
