Sanding the Wood to Refinish a Door Jamb

MARK BLOCKER: Hi. I'm Mark Blocker on behalf of Expert Village. In this segment, we're going to cover sanding the door jamb. As I showed you on our tools section, I'm using a basic hand sander that holds a one-half sheet of sand paper. As you notice, you have overhang past the edge of the sander. A little tip: if you tear these corners back and then remove them, it will allow you to fold this over, makes a good crisp clean, corner, for when you're operating in the corners here, and that way you can sand against both surfaces at one time and get a good crisp even line in the corner. Otherwise, the sandpaper is likely to bunch up and ball and could leave gouges or deeper scrapes in various areas as you're attempting to sand. So now that I got my sander prepared for the job, I'm using a 100-grit first and we're going to smooth this putty down. And our basic goal here is to--to knock down the top part a little bit, smoothen out, but just to roughen up this wood and stain so that the primer has a better base to adhere to. And I'm going to start with the large flat surfaces first and go long smooth even strokes. And, remember, at this point you would want to wear a mask. And as you can see by the white dust, I've just barely scuffed it and roughed up that surface, and what I've done is sanded it to a clear coat on here, and that leaves scrapes and dullness and that gives a surface for the paint to adhere to. Also, if you noticed, it didn't require a whole lot of effort or time to sand that large area. A power sander in this application was just too extreme, it's going to remove material fast and it's going to make it hard for us to keep the surface flat, as well as smooth. The next step is come in to the corner and repeat the process. Maybe add a little putty, then a little bit of extra time there, get the putty knocked down. Long smooth, even strokes. Inspecting, checking your corners. Make sure everything has been fixed, step over to the next edge...duplicate the process...then to the outside of the moulding...remembering at all times to keep this sanding path flat to the surface you're working on. Anyway, please watch our next segment on "Sanding the Door Jamb, Part 2."
