Most commonly reported coating defect is flaking due to:
Inadequate surface cleaning prior to coating
Solution: Clean the surface of all oil, dirt, dust, etc. prior to applying the paint.
Too thick of a coating
Solution: As a rule of thumb, always apply the thinnest coating: a little is good; a lot is not good
Heating to use-temperature prior to thoroughly drying
Solution: Dry the painted coating completely before placing into a use-environment/hot-furnace
Coating over another type of coating such as bone ash or red mud.
Solution: Use Z-PRIMERCOAT to seal in any residual bone-ash/red-mud.
Also common is blistering due to:
Heating prior to thoroughly drying
Solution: Dry the painted coating completely before placing into a use-environment/hot-furnace.
Brushing onto a hot surface above about 170 F.
Solution: Cool the substrate until the brush does not ‘stick’ and the paint goes onto the surface smoothly.
A surface at 100-125 F(40-50 C) often is good for brush application. See our Painting Instruction Guide for more information.
