Wall chalkboard sealant

Hi all, I've painted a chalkboard using rust oleum magnetic chalkboard paint on my wall. It is quite rough, it almost seems to have lots of grit on the wall which wasn't there before I started, and doesn't appear to be in the paint. I assume it has small iron filings to make it magnetic, but parts of the board without the grit are magnetic. That aside though, I want to be able to use chalk pens on it and have it clean up easily. So far, even normal chalk is taking a bit of cleaning. From what I read I need an acrylic sealant. But there are so many and I'm a bit overwhelmed with choice. Add to that they are pricey, and I don't want to waste money on the wrong thing! I saw a rust oleum "Clear sealer" in a tin at b and q. (I can collect today so that's appealing). Is this the right idea? Thanks in advance. submitted by /u/theysayimquirky [link] [comments]
