Normally efflorescence is only of cosmetic concern although it can ruin the appearance and physically damage paint coatings. Efflorescence is most often the result of uncontrolled moisture movement caused initially by poor design details and poor construction techniques.
As you saw above, you need the sealer penetrated down below the surface to stop efflorescence. The problem with then painting the surface is that the sealer can be a bond breaker and might not provide good adhesion for the paint. Note: There are paint store products termed primer/sealer for paint.
