Paint Trim First

in a sprayer. I'm always doing the trim first. And the reason why I like doing that is I like to mask onto a smooth surface in your trip. Trim typically is smooth and will be painted with a semi- gloss paint. So, you'll be able to mask onto a smooth surface and that will always give you the straightest line versus masking onto a wall, which is typically like an orange field texture and it's going to be rough and it's just not going to give you a smooth surface to mask onto. So, always do your trim first and then go on to your next step.
