Advice on painting over bright colours

"1 or 2 coats of shellac primer to totally block the colour, then proceed with the duck egg blue."

"Before painting over bright colours, lightly sand the area to be painted to give it a nice key for the paint to grab on to, then paint with white emulsion to dull the colour a little."

"Hi there,

If you paint the walls white then add the colour it will look nicer."

"First white wash the walls then wait for it to dry.
After this you can apply what ever paint colour you want.
Thanks"

"Paint over with white 1st. White washing it’s called. This will give you a base, then apply 2 coats of wall colour.
Hope this helps, many thanks.
Ronnie."

"I would cover wall with neutral colour first. Probably two coats to ensure colour is accepted and displays as intended."

"The duck egg should cover it in two coats but maybe apply one coat of white first."

"Give your walls a good sand down, base coat it first to match the the paint you want then cover with 2 coats of your chosen colour."

"Apply 2 base coats of white emulsion followed by 2 coats of duck egg."

"Use bare plaster paint first maybe 2 coats. Available from Screwfix, then your new colour,

"Hi, I would give the area a coat of white first then when it's dry give it a light sand down if needed and prep area ( fill holes) and 2nd coat of white again if you think it needs one, then you will be ready to paint in the colour you want."

"Quickly sand the walls down to give it a key and remove any snots etc then paint white with normal emulsion and apply the duck egg colour."

"Will need 2 coats at least. Fill in any holes in the wall with polyfilla once it's dry sand down the excess fill until it's smooth and even to the wall then dust off wall. Then paint and leave to dry, then apply the 2nd coat."

"Hi, to paint over a dark colour wall (orange) you will need to lightly sand down the whole wall and give it 2 coats of white, then when it's dry paint the wall what ever colour you need."
