» Solvent or air trapped in film escapes during drying leaving pop marks
» Incorrect viscosity, spray pressure, flash time, or improper drying
» Incorrect choice of hardeners and/or thinners. Use of fast-dry thinner/reducer, especially when the material is
sprayed too dry or at excessive pressure
» Excessive film thickness. Insufficientdry time between coats. Too heavy application of the undercoats may trap solvents causing popping
» Incorrect drying of primer/ fillers
» Improper surface cleaning/ preparation
» Infrared facilities too close
» Baking started too soon after applying,temperature too high

» Thoroughly clean areas to be painted
» Select suitable thinner or reducer for shop conditions

» Allow sufficient flash and drying time.Allow each coat of primersurfacer to flash-off naturally - DO NOT FAN

» Apply film at recommended thickness

» Follow technical recommendations of
products in use

» If damage is extensive and severe,paint must be removed down to undercoat or metal, depending on depth of blisters; then refinish

» In less severe cases, sand until smooth,resurface and refinish
