One of my bedroom walls has dark blue paint that in places has crazed? To my uneducated eye, it looks like maybe someone has painted on to a wall with wallpaper paste residue still on it.
If it is wallpaper paste, when i paint over this, is it likely to craze again?
Should the crazed areas be sanded before painting?
Or can i maybe roller on some zinsser?
Thanks
