I had three stripped-out screw holes where my upper door hinge attaches to the door frame. Since there are only two hinges, the door was kind of flopping around loosely. This is the front door to my apartment, so it's important that I keep it locked when I leave. And the only way I could lock it was by lifting the door by the door knob and pulling it shut so it could latch. I was going to inform my landlady, but she kind of freaks out whenever I call her with a problem -- so I decided to attempt to repair the stripped-out screw holes myself, and leave the poor lady alone. After reading some of the reviews for this wood filler, I decided to order it and give it a go. I received the product a couple of days ago. I decided to start with one screw hole -- just to see how it would work. So I splooged a fair amount of the wood filler inside the screw hole, pushed it in with a jeweler's screwdriver, re-splooged some more in, and continued the process until I was certain I'd really filled the hole up as much as possible. ("Splooged" is a scientific term; you can look it up!) I then let it set overnight, and attempted to screw the screw back into the hole. The entire endeavor proved fruitless. The screw went in real loose, and kept turning sloppily -- no grip whatsoever. Undaunted, I went back to Amazon, and proceeded to read some of the Q&A's on this wood filler. One suggestion I read indicated that one might insert a toothpick or a wood sliver into the hole, along with the filler, and that might shore up the hole effectively. However, I had no toothpicks. But I did have an old pine board that wasn't doing anything in particular. I decided to kind of cut into the board and produce two good-sized slivers that were thick enough so that I could hammer them into place within the screw hole, after I applied more wood filler. Again, I let it set so it could harden. Before I attempted to screw the screw back into the reinforced hole, I decided to smear more wood filler all over the screw's threads, just because. And who was gonna stop me?! No one, that's who! Finally, I began to carefully and slowly screw the screw back into the hole without re-drilling. Right away, I noticed a big difference. There was a lot more resistance present as I hand-tightened the screw with my handy dandy screw driver. When the screw was flush with the plate, I really reefed on it to see how tight I could get it. Success!!! I tightened the screw as much as was physically possible, and it appeared to hold beautifully. I followed suit with the other two screw holes, and was successful on both counts. Problem solved! I hope it holds. However, I'm not certain how much the wood filler played a part in my repair job. I mean, it could've just been the slivers of pine alone that did the trick. Or maybe it was the combination of the pine-sliver inserts and the wood filler that proved effective. I'd like to think the latter is correct, because I sincerely wish to justify this purchase. So, that's the reason for the four-star review. Hope this helps! Thank you very much. Goodbye.
