Forget the spray methods and read this thread. I’m currently having 100% success doing it with a paint brush, and will shortly be posting more of my work in the finished creations section.

New tile engraving method - Community Laser Talk - LightBurn Software Forum is a long thread but it cost nothing to read and will save you trying the same failed methods that others have tried.
