Do I need a white coat over magnolia walls before repainting?

Hello All, I have a number of walls which are currently painted magnolia and am currently considering repainting them in a light grey colour. Should I use white paint to prime the walls before the grey paint, or would I be able to go straight for covering the magnolia with light grey paint?
Thanks, Gill

"You will be told that you won't need to undercoat the walls - true but depending on how light a grey you may need several coats. To get the best result I would reccomend a white or grey undercoat."

"Hi, You won’t need to paint the wall with white paint first, you can go straight to painting over with grey. If you think it needs it, do two coats of grey, to ensure that you are having the full colour from the light grey. Typically, it will require the second coat. Hope this helps."

"It is not necessary to use primer before applying the top coat, you may need to apply one extra coat of light grey in order to cover up properly the existing magnolia colour but thats all, hope it helps!!"

"No need to prime with a white only do this if covering a very bright or dark colour if going lighter thus means less coats and a better cover."

"You could do but as magnolia is not a deep colour you should be able to go straight over it, worst case it may take two coats but that is normal for the best finish."

"Should be ok to paint straight over however 1st should be a misscoat
And I recommend dulux trade paints as these have more pigment and will cover better than any off the shelf paints"

"You don't really need to paint it white before colour but Trade's people do it for best results so yes, do the base for the colour like a pro and 2 coats are mandatory, always ;)"

"Depends if it's vinyl, silk or matt. Give it a good sand down over your old paint if it is silk and use a primer to cover old paint."

"Normally you don't need to paint it white first because you will have grey on top, but from my experience I'd do a white coat first to have a proper finish of grey and to not give to many cores of grey."

"No painting over with the grey will be fine make sure you give it a minimum of 2 coats. It may need a 3rd depending on how well the paint covers let it dry & see if it's solid"
