Might not hold to painted surface over a period of time,rather idearly you need to flick onto a bare cement surface.But you could try painting (not pva ) SBR over they area then applying mix.
you need to apply 3 coats 1 from the front and 2 fron a left side at a 45 degree'angle and same from the right
