Painting a home on site creates several challenges to an effective paint job.

In fact, paint manufacturer guidelines state that painting shouldn't be done immediately after a rain, during foggy weather, when rain is predicted, in wind, direct sunlight or when the temperature is above 90 degrees. Why?

  • If humidity is high, paint will dry too slowly, causing the risk of blemishes commonly referred to as 'moisture blisters.'
  • The surface must be dry and free of mildew, oil, dust, and other contamination, otherwise there will be adhesion loss. Inadequate surface preparation is the most common cause of diminished paint performance.
  • High temperatures and direct sunlight can cause paint to dry too quickly, not allowing paint enough time to flow into a smooth, consistent finish.

Houston has an average of 105 days of rain, 97 days above 90 F, and 208 days of high UV exposure. However, because painting conditions are always perfect inside the James Hardie ColorPlus factory, you can see why it is the best choice for your home.
