What happens here

Interior painting requires a slightly broader selection of tips. For small trim pieces (3 inches or smaller), a 310 fine finish tip is recommended. For larger trim, such as 4-inch or 6-inch trim, a 510 fine finish tip is generally used. For interior walls in new construction, especially bare drywall, a RAC X 1221 tip is suggested for spraying walls, ceilings, and closets efficiently. For repainting existing interior walls (e.g., rentals), a RAC X 619 tip is preferred. The presenter emphasizes using larger tips for interiors to allow for more paint volume and faster application, which helps minimize flashing.

Goal: This step outlines tip selection for interior painting, distinguishing between trim sizes, new construction walls, and repaint scenarios, emphasizing efficiency and avoiding flashing.

exteriors. When it comes to working on the interior of a house, there's a a little more of a selection that we use, but we're using um for all of our trim. If the trim is small trim, if it's anything like 3 in or smaller, we're typically using a 310 fine finish tip. If we have like 4in trim, 6-in trim, we're typically using a fine finish 510 tip. So, we keep those two tips in stock. We keep a 310 and a 510 in stock on our vehicles for doing interiors. It's very rare on um that we'd ever use a 210, but we do keep 210s in our vehicles. And sometimes on the exterior, if we're doing small spindles, like 2in spindles on deck railing, we'll use a 210 tip. But on the interiors, we're using 310, 510. And when we're spraying the walls, we're typically using, if we're spraying the interior of a house, we're going to be using a bigger tip than we do on the exterior. Exteriors, we use 515s, but on the interiors, we use larger tips because we want more more volume of paint. We want to be able to spray faster. So, I'll talk about the interior wall tips right now.
