I used Dulux™ undercoat and primer today for the first time. I cut in a small area and as soon as I started rolling, it was removing the paint! I had committed so I carried on. I let it dry and did a second coat, which was better. My questions are:
- Why did the paint peel off? I never have this problem with any other paint. (Walls were filled, sanded and washed prior to applying primer)
- Also if I very lightly sand will it make the job good again and will the sanding take away any effectiveness of the primer?
I am reluctant to use primer again and I have another room to do. Is a mist coat as effective as a primer paint. My goal is for the touch up jobs not to come through and to cover a darker wall with a lighter paint.
