Paint Problem Solving Questions.

1. I painted some steel 2 days ago and the paint is still soft - what is the problem?

There is a number of different reasons why a coating does not cure within the usual time frame. This could be because:

  • Wrong amount of "B" component used - too little or too much.
  • Poor drying conditions: drying area too cool.
  • Inadequate flash-off time between coats.
  • Solvent too slow.
  • Incorrect spray technique - application too heavy.

To help speed up the process, the drying are should be well ventilated & warm; and drying may be accelerated by increasing booth tempartures after spraying.

2. My paint finish has whitish/milky spots, where water has landed - how can this be resolved?

For minor water spotting problems, the best repair method is to polish the affected area(s). For major problems, you would need to sand smooth, then repaint. To prevent water spotting happening again, follow the recommended cure times before washing or exposing to rain; increase the spray booth temperature, and use a two pack paint system.

3. I have little blisters/bumps appearing over my new paint work - how has this happened?

Liquid solvent becomes trapped in the paint film when the surface layer skins over too quickly, preventing their evapouration into the atmosphere. Solvents that vapourize within the paint film leaves bubbles, pinholes or craters as they push through and pop the surface.

Solvent can be trapped due to:

  • Thinner/reducer evaporating too fast for spraying conditions.
  • Inadequate flash time between coats.
  • Too much air movement causing surface to skin over before solvents evaporate.
  • Excessive film thickness or pilling on of heavy/wet coats.
  • Excessive purge/flash time before force drying.

There are a couple of different ways to repair Solvent Popping issues. For a minor problem, allow the finish to throughly dry/cure, sand smooth and refinish. Inspect surface carefully to ensure all craters have been removed. For a major problem, remove the affected film. Prime, seal and recoat as necessary.

4. My paint is not drying as fast as it should be. Why is this?
