No store bought laser will give you an actual line you can reliably see in

Goggles and masking tape backgrounds help, but this is certainly an
issue.

Also they will not give you an actual line, just a single dot.

I've just bought a new £50 level for tiling - a pendulum mechanism
with a horizontal and vertical line generator lens on it (not a
rotating mirror). Two excellent lines, which are really intended for
indoor use square-on to the wall, but they still make a useful
horizontal line for outdoor use, projecting along the surface.
