Painting white over blue wall- Diaster?!?

After having my bedroom blue for quite some time, I decided to paint it all white. Thinking it was a simple task, I bought some white emulsion and a roller and started to paint over the blue! However, the blue is showing through in patches even after painting over it several times.


At this point, I searched online for the reason and read some articles about painting over darker paint and some suggested to use a 'Primer'.


What can I do now?


Can I just paint the primer all over the white paint?


Help :(Painting white over blue wall- Diaster?!?
Yes, you can paint the primer over the new paint. You might want to consider using a primer like Kilz which is made to hide everything on a wall before you paint. I once covered a streak of red on a white wall with Kilz, and then painted the wall light blue. No problem.Painting white over blue wall- Diaster?!?
The cheapest way would be to paint on pva after a couple of hours you can safely emulsion over. PVA from Wicks or B%26amp;Q.
yes just paint the primer over and then continue with your white paint..Use a light coloured primer though
You could use lining paper to wallpaper the room. It will be a parchment colour then and you emulsion over that.


The advantages are that it will be a very smooth finish.
go and buy wallpaper instead
man Ive been painting for 20 years just primer the wall completely then paint . '; several coats'; should have covered it. What do you mean by white emulsion? and yes paint primer right over paint anymore specific Qs just email me through answers good luck from TEXAS
First off, I don't know how strong is the blue on the wall. Sky blue or Bic ballpoint pen ink blue.





First, you need to determine where those patches are and why. Is it places where the hands have been alot(near light switches or electrical outlets) or door edges. Your skin has oils which impart onto those surfaces. Painting over the oil, the paint(if it is water based tends to ';not want to go there'; as oil and water do not mix.......so if anything, it will go over that area thinner as the oils are continually trying to push the water out of the way. You would see it as ';beading'; on a car for wax does the same thing.


If those are the areas, all you can do is wait until dry(as what is written on the can) scuff up the surface with some 120 sandpaper and give another coat on those areas. But it has to be applied over a dry coat of paint - not semi wet.





If the blue is bleeding thru the paint(in that it looks like the blue dissolved with the white wet paint and is coming thru as a mix of blue and white.....that is a different problem. (this would more apply to the Bic blue walls. More likely that is concentrated colorant. You need to stop the colorant from progressing. You need a ';stain stopper'; such as KILZ in a spray can. which you apply over the problem area. It will be like spraying on a whitish varnish onto a door(not so much that the Kilz runs, just put on a decent coat. Let that dry an hour on a warm day. That will have stopped the colorant bleed thru in its tracks. Just paint right over with the wall white. It may take 2. Always plan for 2 in any paint job,


If you include the primer, then 3.


Primer is used mainly on unpainted surfaces such as bare wood or unpainted other surfaces. It is the binder between paint and the surface. Wait till that fully dries, so you can run your hand over the surface and feel the surface to be sure that it is smooth to the touch(otherwise out comes the sandpaper to smoothen it a bit - 120 is a good grit in general to have for walls) The first color coat is just that , the first. Wait till that dries to the touch again(overnight is the best) You should not be able to scratch it off with your fingernails if you did the ';blackboard thing';. If it comes off, it ain't hard yet. Or if it seems soft in spots, those are problem areas right off(suspect oil behind the latex) You need to stabilize that(use some Kilz) .


This is why washing the walls down clean on a previous paint job is so important.


The second color coat is applied when the first coat is dry hard. The second coat covers over any thin spots or misses you may have done in when applying the first coat(besides that, dents and imperfections in the wall show up better in the color coat than on plain white - which is normally the primer color. So you still have a chance to fix the minor dents and dings.......before the second coat.


Now, some colors cover over better than others.....so too for brands of paint. A cheap paint is like water, and a more expensive paint is less like water and more like paint. So, whether your wall takes 3 coats or 5 really doesn't matter. Except you could, after the second when it should all be the same, go over the areas that stick out with an additional coat just there to hid the spot. Wait till that dries and then do the whole wall again. The idea is to get an even finish top to bottom left to right.
Just go over what you have with primer. Do two coats to be safe. Be patient and let it dry in between coats, that is important! Once it is fully dry, you should be able to paint the walls anything you want :)





Always always use primer..
Did something similar a few weeks ago. Three coats did the job for me.
YEP SURE CAN..





Just get some stuff called Kilz from home depot or lowes and paint right over what you just did..let it dry for about half and hour and then paint over with the color you want..you probably only need one coat since you said the blue is just showing through some.
Kilz paint is great ,try the primer then start over with the paint
Am i right in assuming you bought your paint from B%26amp;Q or Wickes or such like?


If this is the case then the paint they sell is very weak and watery - even their Dulux range.


The only thing you can do is go to a professional paint or decorating supplier and ask them for Dulux Trade. You will find it is much thicker and covers better. Paint one or two coats with this and you will not see any more blue guaranteed.


One more tip - leave it a day to dry out before you paint 2nd coat. If you paint 2-3 coats in one day it will not work as well.


Do not use a primer at this stage as the first coat you painted acted as a primer.


I would not use PVA on the walls as it will form a skin.


Using cheap paint will cost more in the long run.


Have fun!
