If the blisters do not extend all the way down to the base material, remove the blisters by scraping and sanding. Then repaint the surface with a quality acrylic water-based interior paint.

Finally, remove the blisters by scraping and sanding, followed by a coat of the appropriate primer. Finish it off with a top-coat of quality acrylic water-based interior paint.
Many contractors will do free estimates. See details of Cape based consultants and/or Johannesburg based consultant.
