Issue: When painting on rough surfaces like concrete, paint has been bleeding through the edges of masking tape (painter's tape). The bleed makes edges of the objects appear fuzzy.
Workflow: I clean the surface (which already has a base coat of primer/paint). I then use masking tape to create stencil-like outlines of letters, shapes, etc. After that I block in the stencil using a paintbrush with water-based acrylic. Once the paint is dry, I remove the tape (revealing the bleed).
Question: How can I reduce the bleed to make the edges appear sharper?
