Tips and warnings

  • A pressure washer may work well in removing paint from an outside concrete wall, but use caution as it may damage the surface.
  • Wear gloves when handling acetone or paint thinner.
  • Use caution when handling sharp objects.
  • Do not use a heat gun too close to a window; the heat could break the glass.
