What happens here

The presenter, dressed in a full protective suit and respirator, introduces the third part of the video series: applying the topcoat. He explains that applying the topcoat is similar to applying the PVA primer but requires a slower, heavier application to saturate the walls without causing runs. He reiterates the use of a 1221 spray tip with a 30-inch extension. The project plan involves painting walls first, allowing them to dry for a day, then masking the walls before spraying the ceilings white. The trim will be stained and lacquered separately by the builder. The sprayer will be set up outside, cleaned, and loaded with the topcoat, operating between 2200 and 3000 PSI depending on the paint's consistency and desired spray pattern.

Goal: Understand the process and prepare for topcoat application.

So, here we go. Now, we're going to be stepping on to uh part three for this video, and that's actually spraying the top coat. And the and there's not a whole lot of difference when it comes to spraying the top coat versus the the primer, the PVA primer, except that I'll be spraying a lot slower and getting it on really, really heavy. I want to really saturate those walls and get them soaking wet with paint. Uh not to the point that it's going to run, but pretty close to that point. So, I'm going to be using a 1221 tip again with my 30-in extension. This house, the ceilings are going to be pure white. So, we'll be spraying those after we do the walls. So, I'm going to be doing my walls first and then I'll be spraying my ceilings. The trim is actually a stain package. Everything's going to be stained and lacquered. And the builder on this job wants it all stained and lacquered down and then installed. So, uh, we're just painting the walls in this job and they're doing the stain and lacquer package themselves. But if I was actually doing the stain and lacquer package myself, I'd install all the trim stain and lacquer grit. Then I'd do my walls and ceilings. And but um, when I'm doing that here, we're just doing the walls and ceilings, and we're doing two colors. So, I'm going to be spraying my walls, and then I'll be masking my walls, dropping it with plastic, and then spraying my ceilings. But we'll give the walls a day to dry and then we'll come back and spray the ceilings. So once again, I got my sprayer set up out there. I just quickly cleaned it out and now we got our top coat loaded into it and I'll begin spraying it. It's set up at 2200 PSI and I'll play around with the pressure, but it's going to be somewhere between 2200 and 3,000 PSI. Be using a 1221 tip, a 30 in gun extension. Don't forget all those tools and accessories can be purchased on my tool store. You can just click on my tool store link right there. That'll take you right to my tool store where you can purchase any of my tools and accessories. And so here we go. I don't got to spray the ceiling. So I'll be just doing the walls and we'll be saturating those walls. Here we go. And once again, this process is a lot like doing the PVA primer, but just a lot slower. We're getting our sprayer set up here now. getting our uh product uh set up in here. We're using a product from SH Wind called Treasure Valley Hake Shell. And this is a really good new construction paint. Sprays very well, hangs…
