How Pros Paint Exteriors Flawlessly With an Airless Sprayer

What happens here

Adjust the spray gun's angle to suit the specific area being painted. For example, shoot downwards for lower sections and upwards for higher sections to hit the entire surface effectively. While the ideal technique often suggests keeping the spray gun 'square' (perpendicular) to the surface to prevent 'arcing' (swinging the gun), minor arcing is usually acceptable on rougher exterior siding, especially when using extensions. However, for fine finishes such as trim or cabinetry, maintaining a strict perpendicular angle is crucial. Be aware that extensions can sometimes cause slight 'spitting', which typically goes unnoticed on exterior siding.

Goal: Properly adjusting the spray gun angle for different surface orientations (downwards, upwards, or flat) and understanding the impact of 'arcing' helps ensure complete coverage and minimize issues.

because you've hit that twice. Keep an eye on it for runs. So, you can see I'm shooting down at a downward angle to hit that. So, I'm shooting down, shooting at an upward angle to hit that. Some people will say, "You're, aren't you supposed to have, you know, your um gun square to the surface while you're spraying and not arcing? There's a time and a place for everything." And arcing is not going to cause issues. Yeah, in uh theory you want to have it square, but the arcing, not an excessive arcing. Throwing overspray everywhere is not going to be a big deal. When you're using extensions, you can see it spits. Um that's the nature of extensions, but you'll never see the spits on exterior siding. It never matters unless you're spraying something fine finish like trim, cabinetry, furniture, etc. So, I'm hitting this
