Hi, I'm James with JNC Home Repair, today we're going to show you how to prevent and repair rotten wood. Some basic tools and materials you're going to need for this job. You're going to need some basic wood filler, OKay? You want to make sure that it's rated for interior/exterior, and also if it's paintable and stainable. If you're planning on painting or staining whatever you're preparing later. This is another product, here, it's all purpose putty. This stuff is going to dry a lot harder and and it's probably going to last a lot longer than your standard wood filler. This is a two step process, it's a little bit more involved as far as using this product, but this is a good product. You're going to need, basically, like a razor knife, a five-in-one tool, and a wire brush. OKay? The first thing you want to do is, wherever your damaged area is, you want to go ahead and use your scraper, or your five-in-one, and you want to go ahead and clean out all that damaged wood. You want to get all the old stuff out of there. That way, whenever you go ahead and apply your wood filler it's going to stick a lot better. It won't stick very well to rotten wood. If you don't clean it out, it's not going to work. So you basically want to use your scraper, you want to go ahead and clean out the area, go ahead and take your wire brush afterwards, go ahead and use it as far as getting the old paint, the old debris. You want to get all that stuff smooth and get it nice, you want to prep the area very well to actually let this stuff do it's job and do what it's suppose to do. After you've prepped your area, you've got it clean, you actually want to take your wood filler, just like this, and basically you can either pull it out with your fingers or you can use the putty knife, depending on the size of the area that you're trying to repair. Then once you've determine that, you can just take your scraper, and you get in here and get your wood filler out and it's ready to be applied. After you've applied your wood filler and you've got whatever area that you're trying to repair, repaired. You're basically going to need to sand it down. You're going to need a sander, some kind of a sanding block, sandpaper. I mean you don't want to sand it down smooth to match the rest of the wood that's around it. If you've got a textured type wood, you're going still need to sand it down and you can actually use your scrapper on the wood filler and you can actually work some little texture into the wood filler to kind of help match the existing finishes.
