When bubble-like swellings occur on the surface of the paint film, as early as a few hours or as long as one or two days, after painting, the defect is termed Temperature Blisters.
Possible Causes |
Solutions |
• When Liquid Thinners in Fresh paint Change to Vapours after a thin, dry skin has formed on the outer surface of the film. • Usually, oil-base paints blister this way. |
Follow the direction of the sun, when painting to avoid temperature blistering, around a building. |
Dark Paints absorb more heat and are more prone to temperature blistering than white paints. |
• Paint the north and east sides in the morning, after the surface has been warmed. • Paint the south and west sides in the afternoon. |
Thick Coats of Paint are more likely to Exhibit temperature blistering than thin coats. |
• Let the paint dry for a few days (If temperature blistering has formed). • Scrape off the blisters. • Smooth the edges with sandpaper • Repaint the affected area. |
