Review: Made the corners perfect - Made the corners so easy to skim coat! They turned out flawless!
Review: Perfect to fix bullnose corners - All the outside corners in my house are bullnosed, and with kids and others running around many of the corners get smashed or dinged. I've tried to repair freehand, but the result is pretty ugly. The other issue is the corners sometimes pop off because the builder did not tape them, instead opting for little staples. Finally, I had the inspiration to search for a corner trowel and found this jewel. Sometimes I need to pull the metal out a bit where a kid misjudged the corner playing tag, or drive a screw where the corner has popped, but a little 20-minute mud and this trowel make short work of the fix. In my case I spray a little canned texture and the corner is as good as new. I've amassed a lot of nice tools over the years, but for the price I can't think of another that so simply and perfectly delivers on its promise. Thank you Warner Manufacturing!

## Questions & Answers

**Q: Can this be used with wood filler to repair decayed wood?**
A: My answer is maybe.  It would depend whether or not there are any aromatic solvents in the wood filler. The bull nose trowel is made of plastic and would probably be ruined if it came in contact with any super solvents such as acetone, mek (methyl ethyl ketone) etc.  If the wood filler doesn't have any strong solvent odors then it would probably make a fine mold to make 3/4" round corners...it sure does a fine job with drywall mud on a bull nose corner.  Hope this helps you out, good luck with your project.  Bob W.

**Q: Is this food grade plastic?**
A: Probably not and it doesn’t matter. This is for rounded corners on wall.

**Q: Can this be used as a cement edger for minor end of driveway repairs.**
A: Yes, this could be used for a bullnose on any form of shaping material such as cement/concrete but keep in mind the item is designed for corner bead mudding to provide a smooth finish corner for minor sanding, just keep in mind this item is made of a plastic material and using on cement might act like sandpaper and wear it down more, so for a one time project maybe two, this will do the job.

**Q: Can it be used for inside corners?**
A: If you mean the inside corner as in spin the piece around that won’t work. There’s too much of a graded area behind it so it’ll stick out from the wall a quarter inch.

### ⭐⭐⭐⭐⭐ Did not arrive as promised(Amazons fault)
*by O***R on July 3, 2023*

Amazon delivered a package for my wife today but could not be bothered to deliver mine, I need this tool to finish refining bull nose corners being worked on, just need to touch up the corners ahead of the painter. The way Amazon delivers, probably won't see this item tomorrow in the daylight, Prime seems to deliver to me at dusk or later. Ordered Friday with two day delivery making it Sunday so the touch up would be done Monday morning. Not happy I've used this tool in the past it is a good tool, Warner makes a good product, but they do wear out after many years of use.
