So I have a question regarding paint vs paint and primer.
I have been painting my house, and admittedly, I have not been using primer. The baseboards, however, are a darker color, and painting them white has taken several coats (somespots up to 4 coats) to get the old color to cover. I have gone through a lot of white paint because of this.
My question is, if I use primer now on the baseboards, will the tint be off because of the primer underneath as opposed to just the original paint color and paint? I'd hate to have to reprime and paint all the baseboards I have done up to this point, but if priming them first and then repainting them is what needs to be done, then I will do so. If I can get away with just priming what's left, and painting the white over the primer without a noticeable tint difference, then I will do that.
Also, what is the best color primer to use with white? I was thinking like that light grey primer, but I am not sure the white would cover that very well. I was also thinking white primer, but I think it would be hard to tell the difference between what's painted already and what's only primered (even more so on second coats).
