Primers create a uniform base layer and improve adhesion for the next layer of paint. Relative humidity is very important to the curing of most paints or coatings. As a general rule anything at 70 percent RH and above will reduce curing times to a fairly high extent, too high a humidity restricts the solvents from evaporating, resulting in cissing, Otex with Feelings a good example that a few of us have experienced recently.

For belt and braces, and possibly the chance of some sympathy from Farrow and Ball if it goes wrong! after priming, always use the F&B primer u/c then the Estate eggshell.On previously painted surfaces which are in very good condition, with no obvious problems such as knots or flaking, sand thoroughly. (You could also apply Gloss Off or ESP for belt and braces adhesion) and then apply 2 or 3 coats of Estate eggshell. That should work. This is a glimpse behind the scenes of Traditional Painter.
