What Time of Year is Best to Paint Exterior of House?

Painting the exterior of your house can give it a fresh and attractive look. But choosing the right time of year to do it is crucial for the quality and durability of the paint job. In this article, we will explore the factors that affect the optimal painting season, and provide some tips on how to prepare your house for painting.

The best time of year to paint exterior of house is late spring or early fall, when the temperatures are moderate and the humidity is low. This ensures that the paint will dry properly and adhere well to the surface, without cracking, peeling, or fading.

Why Temperature and Humidity Matter

Painting the exterior of your house in extreme temperatures or high humidity can cause a number of problems. For example:

  • If the temperature is too hot, the paint can dry too quickly and form bubbles or blisters. This can make the surface uneven and reduce the protection of the paint.
  • If the temperature is too cold, the paint can take too long to dry and become brittle or chalky. This can make the surface vulnerable to moisture and damage.
  • If the humidity is too high, the paint can absorb moisture and swell. This can cause the paint to crack or peel off the surface.

To avoid these issues, it is recommended to paint the exterior of your house when the temperature is between 50°F and 85°F, and the humidity is below 70%. You should also avoid painting in direct sunlight, as this can increase the temperature of the surface and affect the drying process.

How to Prepare Your House for Painting

Before you start painting the exterior of your house, you need to do some preparation work to ensure a smooth and lasting result. Here are some steps you should follow:

  • Clean the surface. Use a pressure washer or a garden hose to remove any dirt, dust, mold, mildew, or loose paint from the surface. This will improve the adhesion of the new paint and prevent any contamination.
  • Repair the surface. Inspect the surface for any cracks, holes, or damages, and fix them with caulk, putty, or wood filler. This will prevent any moisture or air from entering the surface and causing the paint to fail.
  • Prime the surface. Apply a coat of primer to the surface, especially if you are changing the color or using a different type of paint. This will create a uniform and smooth base for the new paint and enhance its coverage and durability.
  • Tape the edges. Use painter’s tape to cover any areas that you do not want to paint, such as windows, doors, trim, or fixtures. This will protect them from any paint splatters and create a neat and clean finish.

How to Choose the Right Paint

The final step in painting the exterior of your house is choosing the right paint for the job. There are many types of paint available in the market, but not all of them are suitable for exterior use. Here are some factors you should consider when selecting the paint:

  • Type of paint. The most common types of paint for exterior use are latex and oil-based. Latex paint is water-based and easy to apply and clean. It is also flexible and resistant to cracking and fading. Oil-based paint is solvent-based and more durable and glossy. It is also better at covering stains and imperfections. However, it is harder to apply and clean, and it can become brittle and yellow over time.
  • Quality of paint. The quality of paint can vary depending on the brand, price, and ingredients. Generally, higher quality paint will have more pigments, binders, and additives, which will make it more opaque, durable, and resistant to weather and wear. Lower quality paint will have more fillers, solvents, and water, which will make it more transparent, weak, and prone to fading and peeling.
  • Color of paint. The color of paint can affect the appearance and mood of your house, as well as its energy efficiency and maintenance. Lighter colors can make your house look larger and brighter, and reflect more heat and light. Darker colors can make your house look smaller and cozier, and absorb more heat and light. You should also consider the style and architecture of your house, and the colors of your roof, trim, and surroundings, when choosing the color of paint.
