Preparatory cutting
Before painting the painted wall, give the wall a "clean-up" to clean up the defects and lay a good foundation for a perfect wall.
Putty daub
Don't underestimate this step, putty three times to make the wall more flat. Remember that sockets, door frames and window frames can't be let go!
Polishing stage
After the putty is dry, polish it to make the wall smooth as silk.
Brush details
Weather, ventilation, brushes, every detail is related to the final effect. Before painting, the brush is "slimmed down", leaving only half of the bristles immersed in the pigment. Pay attention to the direction of the brush when drawing, and pay attention to the vertical, horizontal and wood grain.
