Painting in Cold Weather: Tips and Best Practices
As you can probably guess, painting in freezing temperatures can be a little different than painting when it’s 72 degrees. Here are a few things to consider when painting in cold conditions and suggestions to give you the best results possible.
What Happens If You Paint in Cold Temperatures?
Painting in cold weather introduces a unique set of challenges. Here are some common issues to watch out for:
- Slower Dry Times
The liquid in paint needs to evaporate for the coating to dry and harden. Cold air holds less moisture, slowing down evaporation and extending drying times, particularly when temperatures dip below 60°F. The colder it gets, the slower the process becomes.
- Poor Curing
Cold temperatures can disrupt the chemical processes that transform liquid paint into a solid, durable coating. Paint may remain soft, sticky, or prone to damage. It can also lead to imperfections like runs and uneven textures.
- Dry Spray
Low humidity can cause sprayed coatings to dry prematurely in the air, leading to “dry fall” or dry spray. This results in a fine powder that can land on freshly painted surfaces, giving them a rough, sandpaper-like texture. This issue affects both water and oil-based paints.
- Poor Adhesion
Cold conditions can compromise the adhesion of water-based paints, especially if rain or snow occurs within five days of application. Paint applied below 60°F is more likely to peel or fail to bond properly.
- Freezing of Water-Based Coatings
Water-based coatings contain water and can freeze in cold temperatures, which may damage their quality and consistency. Depending on the quality of the paint, it may be resilient to a few freeze-thaw cycles, however, check with your representative for product specific recommendations. And when possible, we recommend storing water-based paints in above freezing temperatures.
Actions You Can Take to Avoid These Issues
To achieve optimal results, consider the following tips when painting in cold weather:
-
- Read the Product Data Sheet (PDS)
Always check the manufacturer’s instructions for recommended temperature ranges. In general, the ideal temperature depends on the type of paint:Oil-based: Can be applied down to 40°F.
Water-based: Not recommended for temperatures below 50°F, unless the paint is designed for low temperatures. - Monitor Temperatures
Ensure temperatures remain above 40°F for an extended period, particularly for exterior projects. - Use Covered or Heated Spaces
If possible, paint in a covered area, warehouse, or heated production facility. If heating a space, be mindful that added moisture can increase humidity levels. - Paint During the Warmest Part of the Day
Aim to paint when temperatures are at their highest and, if possible, in direct sunlight. - Allow Time After Rain or Snow
Wait at least one day after rain or snow, and make sure the surface is dry before painting. Ensure no further precipitation is expected for at least five days. - Choose Seasonally Appropriate Products
In warmer seasons, you may use water-based products such as Water Reducible Alkyds. However, you may switch to fast-drying, solvent-based products like Quick Touch in colder months. - Store Paint Properly
Always keep your paints and coatings in a climate-controlled environment to maintain their integrity
