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

What happens here

Once the preparation is complete, don your protective gear (suit, respirator, safety glasses). Begin spraying the walls, maintaining the gun tip approximately 12 inches from the wall surface. Use a consistent, overlapping motion, ensuring each pass overlaps the previous one by about 50%. For optimal speed and to avoid 'spitting' from the gun, avoid releasing the trigger unnecessarily. Continuously observe the paint application; if the coverage appears too thin or 'dry,' slow down your movement. If the paint is accumulating too heavily, risking runs, increase your speed. The goal is a uniform, saturated coat.

Goal: Achieve a uniform and saturated paint finish on the walls.
