Hello everyone. I've recently had a new room built, boarded and skimmed. Half of the height of the walls are tiled.
In preparation to paint the walls above the tiles, i initially lightly sanded some tile adhesive residue that was on them. I then did the mist coat followed by two coats. For the area just above the tiles, I brushed the paint on and the rolled into it to remove brush lines. However whenever I tried to roll it it felt like it was taking paint away from the area. The result is the pictures which is an awful finish and a border like outcome. Never had that before when painting skimmed walls. Can anyone advise what has happened and how to resolve it?
