My wall was previously painted yellow and dark blue (top-half = yellow and bottom-half = blue) using Solver mid-sheen washable acrylic paint.
My wife wanted to paint the walls in a shade of white and as such, people has suggested I use an undercoat. I decided to use a Solver Low VOC undercoat due to my wife being allergic to the fumes. She and I will be the one doing the painting.
I was looking at the wall and it seems the undercoat is "cracking" (something like http://www.rcdnet.org/Documents/Drought ... %20Pix.jpg) areas previously covered by the blue paint. This doesn't seemed to be happening on the yellow areas.
Should I be worried? If yes, what are my options?
Thank you very much
