Honestly don't bother, paint is nothing like a Farrow and Ball brand paint, the smell, the way it absorbs in wood, tone is completely off, see pictures below in comparison with original Pitch Black paint (the wooden box is in original paint, the sheet underneath is with the paint from PaintStop)

I bought it to repaint some worn out patches on staircase, obviously now it's impossible and have to buy original paint.

The sticker on the can says "mixed to order" and "non-refundable" so there's your clue, shame I missed it and wasted £50 on it.
