Why skimming cracks before painting saves you a callback
Hairline cracks in skimmed walls will telegraph through a fresh coat if they are not opened, filled, and sanded. We rake flaky paint, apply suitable filler, skim where needed, then seal stains before topcoats.
Skipping that step often looks fine at handover, then opens up after a season of heat movement on the Highveld. If you are repainting a whole house or a batch of units, fixing structure first keeps your maintenance cycle predictable.
