The below painting defects we generally see on the field are:
1. Chalking
We can prevent it by not mixing undercoat with finishes.
2. Brush marks
We can prevent brush marks by applying paint at recommend viscosity and as possible as quick.
3. Sagging
We can prevent sagging by rolling the thick patches also and adequately by avoiding thinning of the paint.
