What happens here

This project guides you through the process of rejuvenating a wooden fence by first power washing it to remove mildew and old wood, and then applying a fresh coat of stain. It covers starting and priming a high-pressure power washer, demonstrating the correct technique for stripping the fence, and then applying a semi-transparent stain to the pickets and a contrasting solid color stain to the posts using both spraying and brushing methods.

[Applause] This is Chris in Boise. In this video, we're going to show you how to power wash a fence. We got a fence here in the background that's got a lot of mildew on it. What we need to do is we need to get rid of a lot of that black mildew off the fence. So, we're going to be using a power washer with the 4,000 PSI to actually strip and get a lot of that old wood off the the fence and get a lot of that discoloration before we actually put our stain on it. and it gives um the fence a lot better look if you really strip a lot of that wood off. We're using a 4,000 PSI MITM power washer with a rotating nozzle. And this rotating nozzle, it actually rotates and spins and it actually will strip and tear wood off extremely fast versus using just a flat straight nozzle or a round nozzle. Over here we got the power washer. We'll show you how to start it up. You got the MITM power washer. Come over here and show them the good view of the start. So, this power washer, it has um a gas valve. It's got a choke valve and then an onoff button right here. And we're going to want to turn this on button to the on position. The power washer is cold right now, so I want to turn the choke on. And then what I'm going to make sure the gas is on, and then I'm going to pull start it. The thing will start up really quickly. And then we'll turn the choke off. We're going to be working, you know, one pick at a time. You're going to be going up and down one picket. You got to go really slowly to actually strip the wood off. What you don't want to do is run your power washer and stripper across ways on the fence cuz if you go crossways on the fence, it's actually going to make a mark on the fence that won't go away when you actually stay in the fence. So, you always want to go with the grain on the fence and and strip with the grain and never across the grain. And strip with the pickets. So, you're going one picket at a time and it just takes time and you got to go slow. And now we'll start it up and we'll show you the process. Okay, go ahead. Hang on. Once the power washer is started, it's pretty common for there to be actually air in the line cuz there's when you turn the water on, there's air in the water hose and it's sometimes it's difficult for the pump to prime itself. So once a power washer is started, you want to take off the tip of the the ho the nozzle or the tip of the gun and then Eric's pulling that tip off. Then you're going to want to run some water through it. The the power washer would actually be running at this point in time. And then you'll just run water through the gun without the tip on it. And that actually runs a high volume of water through it. And it's actually running running all the air out of the pump itself. And it helps the pump prime itself. And then you'll take and put the tip back on. Power washer is still running at this point in time. And then you can start running it after that. And what happens is if you don't go through this process after you start it, you'll be power washing and then all of a sudden you'll start to lose pressure and it'll pulsate and come on and off and come on and off. The pressure will go up and down and it's trying to prime itself. So, make sure you take the tip off, run some water through it for about 30 seconds, put the tip back on, and then continue going Heat. Over here, we're going to be spraying the semi-transparent on the fence here. And this is the non 2x4 side. And we're just going to be going up and down on the pickets themselves. And you don't want to spray it crossways. It'll leave lap marks going crossways. You want to make sure you go up and down with the pickets. And the posts are going to be an accent color. So, I don't need to spray the post. I'm using a 515 tip doing this fence cuz the fence is extremely dry. And I'll actually spray some and then I'm going to back brush what I've sprayed to make sure it gets rid of any lap marks or any runs and it helps it absorb into the pores more. And I'll do about twoft section and then continue on. I'm using a Sher Williams stain brush. This is a 6- in stain brush. And this works really good for doing fences and stuff. The brushes last a long time. So, I just keep working my way down the line. Just like that, this the fence will be completely saturated and look brand new once it's done. So, we're staining this fence here and we're working on the posts here. The poster will be different color than the pickets themselves. And we're using a Sherwin Williams solid color woodscapes stain. And it's the colors uh soya color 3015. And we're just using a 4-in knob. I'm also using a China bristle brush, 2 and 12 inch angle sash brush so we can easily cut any edges. And we're just going along and just rolling and staining the post now. Rolling and staining the post gives a nice accent. Makes it look pretty nice. We've actually already we've already stained these with the semi-transparent stain. And so that's all dry now. And now we're doing the post. There's the front side of the finished fence that we've done. Got the post are done in sequoia Sher Williams color and then the pickets are done in a semi-transparent cedar bark color from Sher Williams. Here's the backside of the completed fence that we did. Fence looks brand new after having severe mildew on it.
