Spraying Interior Walls With An Airless Paint Sprayer. How to paint drywall. DIY painting.

What happens here

Begin spray painting the walls, maintaining the gun tip approximately 12 inches from the wall surface. Use a consistent, controlled motion, moving the spray gun parallel to the wall. The objective is to apply a heavy, wet coat without causing drips or runs. Aim for a 50% overlap on each pass to ensure even coverage. Critically, avoid releasing the trigger as you move the gun, especially when changing directions or reaching edges, to prevent paint spits and uneven application. The sprayer pressure is tuned to 3000 PSI for optimal paint atomization and coverage. It's recommended to keep the main paint sprayer unit outside the room to minimize dust and maintain cleanliness.

Goal: Apply a uniform topcoat to the walls.
