Hi, I'm Todd Languell, The Flying Furniture Guy from R&D Wood Shop in Scotia, New York. Today, I want to talk to you about how to repair wood finish. Okay I've got a nice maple stand here, but you could see that it's lacking a little bit on the finish. Now you can wax this, but if I wanted to put another coat of polyurethane on it the most important part is to sand it lightly. You need to pick up a 400 grit piece of sand paper, this is from Keystone Abrasives and what's so great about this sand paper is that this is a silicone carbide non loading sand paper, if you use a wet dry sand paper it clogs a lot and you're going to ruin your furniture possibly. What you want to do is you want to lightly sand in the direction of the grain and what you're doing is you're giving the new finish a spot to adhere to. Now I'm not changing the color to then point where I need to re-stain it, really all I'm doing is scratching the surface. And I'm just going to do this portion right here so you can see the contrast. You don't have to sand the entire thing, you don't have to really go crazy with all the detail, if you want to scratch it a little bit, that's great, but you really want to scratch the main surface areas, just a little bit. Okay and now you can take a tack rag, you can wipe it off with a tack rag or just wipe it off with your rag and you can see it hasn't changed much, but you can see that there's just a little bit of debris, sawdust left on this rag. So I blend my own finishes, but you can take polyurethane right out of the can or spray and you can put the polyurethane right back over the top, put a little polyurethane on your rag, just enough. What you're looking to do, you're looking to wet the entire surface making sure to go with the grain, when you can and when you can't just make sure that you finish it up with the grain. Put a little bit more polyurethane on if you need to, just that much. You can see I got it, I got it running down there because I want to show you the run marks, so really what you want to do is you want to put it up, put on enough polyurethane so you don't have run marks, but yet you get 100 percent coverage. If you have a run mark just go over it with a nice light feather touch, going back and forth again and again until you get to where you want it. And that's it. I'm Todd Languell, The Flying Furniture Guy, and this was how to repair wood finish.
