What you’re seeing below is the result of using vinyl to make custom stencils and not the vinyl itself.
This was a poured concrete floor. The tan color is the tinted concrete and everything else is paint. For this logo area we cut a stencil and stuck it to the concrete. Then it was painted in and the vinyl pulled up. Simple as that. You end up with very clean lines.
This same procedure could be done on a wall or any other smooth surface. Stencils can be cut for sandblasting or chemical etching as well. (Un-stencil related: There is also a semi-transparent vinyl that looks etched already. It can be cut ornately for a front door window or give privacy to your bathroom window.)
Custom stencils can be cut for making tee shirts as well. This would be a unique party idea. Buy your cut stencils and some fabric paint and your party animals each get to give the DIY treatment to their own shirt.
