One of the things we had the most fun with in our bedroom redo last weekend was magnetic paint. I had read about it but had never used it before. So the application was kind of an experiment. I rolled it on over the primer coat. It rolled like tar, kind of disgusting. It also took awhile to dry enough. And then, I rolled the regular wall paint over it. It really covered pretty well in one coat, but I added another just in case. If you had not seen me roll it on, you would not have been able to tell it was there. I made the wall magnetic between John's desk and shelf. He can use that wall as a magnet board. Think of the cool applications for magnetic paint. I am thinking of doing walls all over my house!
Here is is spelling his name on his wall with magnets.
It is almost like a parlor trick; easy to do and it amazes people.
