Paint Failures can be caused by reasons like Poor workmanship, lack of adhesion and incorrect type of paint. Due to this various things like blistering and chalking of paints take place.
BLISTERING OF PAINTS
Blistering of paint is due to moisture which forces up the paint film into little bubbles and is a major paint failure. A Make sure the surface is clean and dry, apply primer before painting and avoid painting in hot temperature.
BLEEDING OF PAINTS
Bleeding is the seeping through of a soluble dye from the substrate through the top coat color. Before painting ensures all contamination, especially bitumen and tar deposits, are thoroughly removed, Carry out a solvent test to check if a soluble dye exists.
CHALKING OF PAINT
Chalking is the powdering of the surface paint due to external exposure and lack of paint binder. It is caused by choosing the wrong hardener, poor aftercare of paint work, color coats applied too thick. To avoid chalking of paints, always use the recommended hardener and mixing ratio and you should do regular paintwork maintenance.
FLAKING OF PAINT
Cracking and flaking can also result when paint is applied too thinly. Inadequate surface preparation can also cause these failures.Proper ventilation can fix most interior moisture problems. High-moisture areas such as bathrooms with showers should have exhaust fans installed.
