Abby warns against using cheap emulsion as a base coat and suggests you use a wall primer or mist coat instead.
She explained: “My biggest tip is to avoid using a cheaper emulsion as a base coat, this is a big no-no if you re then using premium paint as the topcoat.
“A cheaper emulsion will absorb the water out of your paint potentially leaving a patchy finish.
“Instead use a wall primer or a mist coat , a coat of your paint diluted with water, to help promote an even finish.”
