Do I have to paint a wall white before painting it?

Do I have to paint a wall white before painting it?





My wall is regular violet/purple now, and i want to paint it regular green. Should I paint my wall white first before painting it green, or should i just paint with green right away.





Thanks.Do I have to paint a wall white before painting it?
You have to use a primer on it first and primer comes in colors so you can pick one close to your final color. If you do not use primer on such an intense color before painting you could have some bleed through and definitely not achieve the true color you want.Do I have to paint a wall white before painting it?

You will want to use a high-hide primer. I suggest tinting the primer to the same or similar color as the paint. It works well and you will likely be able to get away with one coat of paint depending how think you put it on.

Use a primer and your old color won't bleed though to your new color.
I would use primer as well, white or tinted. I have found that the best covering primer is Sherwin-Williams Pro Block. Every time I have used it it has always covered very well, even darker colors.
yeah you should probably use some primer before painting green over purple





you dont want the purple bleeding thru at all or your green might look a little off

You don't necessarily have to paint it white. It would be a good idea to prime the wall first. I would suggest a primer tinted to match your new green instead of painting white. Not only is primer less expensive than paint, but using a tinted primer will avoid you having to paint 3,4,5 coats of your green to remove the purple underneath.





In a perfect world, you would prime the wall with one coat of white primer, then one coat of green-tinted primer. This is what will allow your green to be the true color.





If you paint green directly over the purple, you'll find that you'll need lots of coats of green paint to cover the purple, and even then, the green will not be the true green you are looking for. Likely, you'll be disappointed in the green.





Hope this answers your question.
i would paint it first with a white latex based stain kill. this will help seal out the original color and give the new paint its true color. you wont have the old color bleeding through to the new color.
if you own the house and want it to maintain value maybe strip the old paint first then prime with white
