All right. In this video, I'm going to talk about how I go about spraying walls and having a lot of success doing them. I'm going to give you some of my tips and tricks. So, hopefully when you spray a wall, you can get professional results. It can look super nice, even without lap marks, without flashing, etc. And the first thing um I'll talk about, I got an extension here. I t You always see me spraying with extensions. I got a gun with a tip. Now, this is a fine finish tip cuz I just got done spraying a door. But the first thing when it comes to spraying interior walls, I highly recommend using Titan HA tips. HA tips have a nice feathered edge instead of like a fine finish tip or production tip. They have kind of a sharp edge which causes fingerings, fingering, tails, lines, etc. Stuff like that. Harder to get a good finish on walls. Titan HA tips is my recommendation. I like shooting walls with a 619 tip. If I want to go um down a little bit lower depending on product, a 517. If I'm on new construction, just blasting something fast, I'd be like a 1221 or a 23. But Titan Ha, high efficiency airless tips. That's my biggest tip that you I can give you when it comes to having success spraying interior walls because of that super nice feathered edge. And it sprays at low pressures. I typically run in it around 1,000 PSI. The next tip I'll talk about is, you know, using extensions. When it comes to spraying walls without an extension, if I'm using just a gun, I have to bend over excessively and I have to reach excessively to do that wall. It's a lot more work for you to reach high, bend down low to do that. It works your back. It works your shoulders. It's just completely unnecessary. Typically, what I do is choose an extension. Like if I got high walls like this, an extension where I can easily reach the top and I can easily reach the bottom. You can see I don't even have to bend over to do this motion to to spray this wall. It just makes sense to use extensions when it comes to spraying the majority of the things you use. You're not going to be nearly as fatigued, worn out at the end of the day. you start to add, do the math. You start doing this for 20 years, 30 years, and you start getting tendonitis in your shoulders and getting back problems, you'll um thank me if you start using an extension. I had an old man tell me that uh one time in the paint store when I was young, and I never used an extension until he uh told me that exactly what I'm saying here. I walked out of that store with multiple extensions, never looked back, and I use them just about on every single thing I do. So, have an extension if you want to have success spraying walls. The next tip I'll give you when it comes to spraying walls and having success is spraying the walls and utilizing good technique and um good pattern overlay. I'm going to start someplace. I don't want to start ever in the middle of a wall. I'm going to start from a logical start and stop over here. The corner is a logical start and stop. I'll start working around the room this direction. I'm going to start in the corner. I'm going to begin overlapping 50% as I go. Doing ceilings and walls, a 50 over a 50% overlap is extremely, you know, important. As you're spraying, what's really, really important is you are actually seeing the paint hit the wall. So, you have to be, you know, 100% focused. You have to see the paint. You have to hear the paint coming out of your gun. Is your tip blown out? Is it hissing? Is it spitting? You got to understand what's going on. You got to be very focused. I'm overlapping 50%. I see that I overlap 50%. It looks super wet. It's not too much. It's not too little. If it looks a little bit dry, I probably need to slow down my speed a little bit. If it looks a little bit wet, like, wow, I might get a run. I'll speed up a little bit. So, I make those adjustments and you'll eventually um you'll just know right off. It'll be just second nature. As soon as you start, you'll know exactly if you don't have any experience at all. It takes a little bit of time, but you'll figure it out. 50% overlap. I'm seeing it as I'm working down the wall. I'm looking down the wall out of my perial per peripheral vision. Do I look like I have a nice wet coat all the way down the wall? Or if my overlap was too much, do I have some like like light dry spots in the walls? That's going to cause you issues. Keep your 50% overlap consistent, keep your speed s consistent, and you'll have some success. So, the last tip I'll talk about is, you know, uh is heat. And too much heat, your paint drying too fast, you know, as you're working down the wall can actually cause you problems. Heat is good when it comes to spraying trim. I want the pre the heat up pretty hot. When I'm spraying trim, cuz I want it to like flash dry really fast. Trim paint is more likely to run than wall paint. Majority of wall paints hang extremely extremely well. And so I like the heat to be down, you know, more in that 65 range when I'm spraying trim, more in the 75 range. So 65 range, it allows it to just smooth out, level out, and gel out nicely over a period of time instead of drying too fast. If if you are walking too fast or your overlap's not right, if the temperature is lower, it's going to help you have some success. So you'll make sure the temperature is right. uh too cold with interior paint. You start to get below 65° and then you could cause running issues with your paint. You don't want interior paint to be in the 50° range cuz it doesn't like that range. So somewhere between 65 and 70 is actually really good for, you know, interior paint. And then the last thing I'll say is you're only as good as the paint you apply. If you apply cheap paint, you're going to get cheap results or bad results. It's really hard to have success spraying or rolling any paint that's cheap. I only use high-end paints when I'm or lifetime warranty paints when I'm working inside or outside. Right now on this job, new construction job, I'm using a product from Sherwin Williams called Scuff Top. Uh it's spraying out amazing. It looks amazing. It's easy to have success when you're using a good product. It's a userfriendly product. something if you've never sprayed before. Hangs really well, covers really well. It's on the trim and walls. I've had a lot of success with it so far. I just started using it and I actually so far like it. I have no idea what how long it's going to um last scrubability and its scuff resistance cuz I don't have any experience with it yet. But from an application standpoint, spraying um it's I've had a lot of success with it in here in varying conditions. So once again, you're only as [music] good as the paint you apply.
