Blistering Paint

Definition:
Paint blistering is when a layer of is lifted from the substrate layer so it appears to be bubbling. It is usually caused by dirt under the paint layer, hot weather conditions, a damp environment, or a combination of these. These conditions will eventually cause the paint layer to peel off.

 

Causes:
• Application of wall paint when the surface condition is too hot or wet due to moisture, extreme humidity, or during rain.
• The applied surface is directly adjacent to a damp wall such as bathroom, kitchen, or laundry room walls.
• The surface of the wall was not well prepared, for example, it was not thoroughly cleaned.
• Mistake in painting system, for example, alkyd paints applied on top of (water based) emulsion paints.

 

Solutions:
• If the bubbling or peeling paint is not wet, scrape off the paint and then sand the wall until it is cleaned.
• Then, apply Mowilex Wall Sealer WB before applying the appropriate Interior or Exterior wall paint.
• If the bubbling paint is wet, scrape off all the bubbling paint untuk the substrate surface.
• Then, apply Mowilex Water Proofing Wall Sealer before applying the appropriate  Interior or Exterior wall paint.
