Trouble Shooting



What to do

Application marks Poor quality application tools.Temperature too hot causing paint to cure too quickly and not allowing the product to flow naturally.
Temperature too cold making the product too thick and difficult to distribute evenly.
Abrade back to flat even surface and refinish, considering applications and temperature conditions
Blistering – small swollen areas, surface may feel like sandpaper to touch Surface contamination prior to paint application.
Solvent entrapment due to paint being applied too thickly or overcoated too soon.
Moisture entrapment during coating.
Paint applied when humidity was too high.
Check for any other areas which may have a similar problem, abrade back all blisters, fill where necessary and recoat
Blushing – white milky appearance on film High humidity can cause the thinners to evaporate too fast. Water condenses on the relatively cold surface and the subsequent moisture creates blushing. Abrade back until blushing is cleared and recoat considering the relative humidity and temperature.
Chalking – poor gloss, powdery surface Prolonged exposure to Ultra Violet rays.
Poorly mixed paint.
For a permanent cure, abrade back and recoat ensuring the paint is properly mixed.
Cracking / Crazing – appearance of shattered glass Extreme temperature changes during paint. Incompatible overcoating. Paint applied too thickly or overcoated too soon. Abrading back and repainting may curing the problem, however, it is more likely that the complete coating needs to be removed and an appropriate coating re-applied in accordance with recommended specification
Fish Eyes – small holes in the paint film Appears during painting due to silicone or oil contamination on the surface. Abrade back until contaminated area can be degreased, allow to dry and recoat.
Loss of gloss High humidity, cold conditions and dew fall will cause the paint to cure with a low gloss level.
Ultra Violet degradation over a period of time.
Abrade back and repaint
Lifting or Peeling – paint lifting or peeling from surface Poorly prepared surface. Incompatible overcoating.
Moisture on the surface.
High moisture level in wood.
Overcoating times exceeded.
Remove loose paint, abrade, degrease and recoat in accordance with recommended specification.
Orange Peel – surface mottled like orange skin. Primarily occurs when spraying due to poor flow caused by poor atomisation, insufficient thinning, paint applied too thickly or overcoated too soon. The same effect can occur with some roller applications. Abrade back to an even flat surface and recoat.
If using a roller, it may be necessary to lay off using a brush or pad after roller application.
Runs – running of wet paint in to uneven rivulets Paint has been over thinned. Too much paint applied. Abrade back to an even flat surface and recoat.
Sags – partial slippage of paint in thick areas like wide runs Paint applied too thickly. Abrade back to an even flat surface and recoat.
Wrinkling – surface resembles the skin of a prune Paint applied too thickly causing solvent entrapment.
Paint applied in direct sunlight causing the surface to dry too quickly resulting in solvent entrapment (uncured paint) under the surface.
If the paint has not hardened, remove with a scraper, clean surface with Degreasing Solvent or Thinners and recoat. On a cured surface, abrade to a flat even surface and recoat.
