ORANGE PEEL
An orange skin effect caused by poor flow out of coating. Common reasons include spraying techniques, thinner amount and compatibility, humid working environment, spray gun air pressure; spray gun fluid tip being used is too small, poor surface preparation and paint quality and shelf life. To prevent this, always check for air pressure pre application and apply consistent spraying techniques.
BLISTERING
Also called Bubble effect, found on the finished surface due to air escapement from substrate pores. Common reasons include spraying techniques, thinner amount and compatibility, humid working environment, spray gun air pressure; spray gun fluid tip being used is too small, poor surface preparation and paint quality and shelf life. This may be due as well to presence of moisture, grease, exposure to direct heat of the sun or excessive amount of heat during the drying process.
CRACKING
Cracks found on the paint film finish due to substrate or coating system movement. This is often due to heavy spraying, wrong coating system application, paint not properly mixed or stirred to correct viscosity and consistency.
FISHEYE
Also called dimple effect, caused by surface tension difference. Common reasons for this defect is pertained to applicator skill, applicator clothing or applicator hand contamination, polluted working environment with silicone chemical type; contaminated equipment, substrate or paint.PINHOLES
Also referred to as small holes formed on finished surface of paint film often caused by poor penetration of coating into substrate pores. This is often due to heavy spraying, thinner consistency or insufficiency, inconsistent working environment temperature, faulty equipment and improper or insufficient surface preparation.DELAMINATION
The flaking or peeling of paint between the top coat and primer or top coat and the substrate. Common causes for this defect include improper surface preparation, painting over oil, grease and other contaminants, improper paint cure.ALLIGATORING
Also called alligator skin, the incomplete form of peeling of paint from the substrate also on one coat from another coat. This is due to incorrect drying time in between coat application, wrong coating system or a contaminated substrate and a cold or moist working environment.MOISTURE BLUSHING
Also referred as having a milky appearance often due to moisture being trapped in the coating. To prevent blushing, ensure that the working temperature is kept constant and humidity kept relatively low.
