How to Stop Paint Cracking, Flaking, Blistering & Bubbling

Painting the interior and exterior of your home is one of the best transformative tools you have as a homeowner. When you apply paint, you give your house a fresh, updated look so it feels like new again. To know how to stop paint cracking and how to stop paint flaking you’ll need to do some preparation work.


How to Stop Paint Cracking

A crack in your paint can start out small but quickly grow into a large crack. From a hairline crack to flakes of paint peeling off, if caught early you can stop this happening. The reasons why paint cracks can occur include:

  • Low quality paint was used
  • The paint wasn’t applied thoroughly and with precision
  • The paint is old An oil-based paint was applied over an enamel paint
  • Primer wasn’t applied prior to painting.

If you notice that paint is cracking, you can simply remove the paint with a wire brush or scraper. We suggest you feather the edges of the crack before priming the spots and allowing them to try. If the cracking paint goes deeper than the substrate, you’ll need to remove the entire layer of paint before priming and resurfacing.

How to Stop Paint Blistering

Paint blistering is caused when newly applied paint detaches from the surface forming a blister or bubble-like bump. This can be a result of painting directly in the sunlight or because there has been moisture pushing the paint off the surface of the wall. Paint blistering can also be caused if:

  • There has been contamination of the surface prior to a new film of paint being applied
  • Poor substrate preparation where old paint and/or unsound paint hasn’t been eliminated
  • Solvents being trapped beneath the painting surface prior to a new film of paint being applied.

How to Stop Paint Bubbling

Paint bubbling occurs when the paint film has lifted away from the underlying surface due to a lack of adhesion. If you have paint bubbles they can lead to peeling. Paint bubbles occur because:

  • The paint has been applied when the room temperature is too hot (over 32 degrees Celsius) or too cold (below 10 degrees Celsius)
  • The surface wasn’t prepared well before the paint as applied
  • Just after the paint dried it was exposed to moisture
  • The paint was applied on a humid day
  • An oil based paint was applied over enamel paint.

To prevent paint bubbles, we suggest you thoroughly dry the paint surface before painting.
