Please see picture - How to hide surface imperfections before painting
 
Please see picture below

I am moving the chair rail up by 4" (This is a old home and chair rail was at 28", and I am moving to 32" from the floor). So i removed the chair rail, sanded the wall and primed. But I can't get the old paint, surface roughness even after sanding and priming. As you can see in the picture on left the old 'band' is still visible after priming with Bulls eye 123 primer.

Any ideas how to hide this 'band' that bleeds throught the primer? Should I use a alkyd based primer?http://i80.photobucket.com/albums/j1...r/DSC01799.jpghttp://i80.photobucket.com/albums/j1...r/DSC01800.jpg

the job of a primer is not to so much hide the differences as much as it is to seal the difference, so that when you paint those "differences" do not bleed through your topcoat. In addition the primer is not designed to blend dissimilar surfaces - if the wall is rough in one area but smooth in another you should take care of that before priming - either by sanding, skimcoating with joint compound, or whatever works for you. Hope that helps you some..Good luck!
