garage internal wall rendering

[loc0]

Good morning . I would like to apply a thin coat of render or plaster to cover up the brick and make nice, unified walls in my garage/ workshop. All I want to achieve here is a reasonably smooth white wall and to make the place brighter, more enjoyable to work. The internet says the cement render should be applied at a minimum thickness of 16+mm in 2 coats. Silicone renders are faff with fibre mesh. At that point, I am leaning towards something like Toupret Joint, Skim & Fill product, which can be applied to anything at any thickness (it would eliminate all the hassle with reinstalling electric sockets etc. Is there any better way of achieving what I am looking for? Is my current idea wrong for some reason? All advice is welcome.

Are you any good at plastering? If not then I would go for a rolled on finish somewhat like artex or masonary paint.

18mm OSB painted white?  Easy to fix to.
