Common Problems When Coating In Cold Weather

There are additional considerations when it comes to protective coatings in cold weather. Issues can arise in both indoor and outdoor environments for every type of coating. Some of these problems are obvious, but others are a bit more difficult to anticipate.

Below we’ll discuss the most common cold weather-related coating application issues and how they can impact your coatings.

What Problems Can Cold Weather Cause for Metal?

Metal is sensitive to environmental temperatures, expanding and contracting as the weather changes. Exposure to cold can also make the metal more brittle and prone to failure. Add in everything that tends to come along with cold weather, from snow and ice to salt and other winter road treatments, and you have a recipe for rapid, damaging metal corrosion.

Low Substrate Temperatures During Application

Most chemical reactions slow as temperatures drop, including water or solvent evaporation and the curing of coatings. Before the coating application begins, it’s critical to check the temperature limits for each product you’re using by referencing the Product Data Sheet. If the temperature drops too low, this can slow or stop the curing process and the coating can be irreparably damaged. Remember, the temperature not only needs to be considered during coating but also the curing window as well.

Considering Temperatures for Material Storage

Colder material can be harder to mix, spray, or adhere to a substrate. Often, applicators will try to add extra thinner to materials that have thickened from the cold. As temperatures drop, the extra thinner will evaporate slower which can cause issues with film build and can also lead to solvent entrapment in the coating.

Condensation on Substrate Surfaces

Cold weather can also cause the formation of condensation on the substrate surface if the surface temperature drops to the dew point. This can ruin clean blasted steel, ultimately causing it to rust. A re-blast can be very expensive and time-consuming. As well, condensation can kill the cure of moisture-sensitive coatings. For example, a polyurethane coating exposed to moisture too early may never fully cure, which would require total removal and replacement.

Low Humidity During Application

Cold air holds less water than warm air, which causes a problem for moisture-cured coatings. If the water in the air isn’t available, the coating won’t cure. Low humidity can be a problem in both shop and field coating environments. The heat used to warm interiors can make humidity issues much worse.

Understanding how low temperatures affect coating application and change the drying, cure, and performance of the coating can help one prepare for application when temperatures are below freezing. Many coatings are made for application between 10° and 38° Celsius.. However, there are solutions, options, and products specifically designed for cold weather applications to cure in the same manner as standard products. This allows one to get the job done in the same amount of time.

In regions where temperatures plummet, maintaining the integrity of infrastructure becomes a formidable challenge. Cold weather can exacerbate the deterioration of structures due to factors like freeze-thaw cycles, moisture penetration, and increased brittleness of materials. This is where cold weather protective coatings come into play, offering a shield against the harsh elements and ensuring the durability and performance of assets throughout the winter months. This article explores the significance, selection, and application of protective coatings designed for cold weather conditions.

The Significance of Cold Weather Protective Coatings

Cold weather protective coatings are engineered to withstand the unique challenges posed by lower temperatures. These coatings are crucial for:

  • Preventing Moisture Penetration: Moisture is a pervasive threat that can lead to corrosion, mold growth, and structural damage. Cold weather coatings provide a moisture-resistant barrier, protecting the substrate from water ingress.

  • Enhancing Durability: These coatings are formulated to remain flexible and effective in cold temperatures, resisting the brittleness that can lead to cracks and other forms of damage.

  • Mitigating Freeze-Thaw Damage: Structures exposed to cycles of freezing and thawing are at risk of deterioration. Protective coatings help mitigate this risk by providing a durable surface that withstands the expansion and contraction of the substrate.

Selection of Cold Weather Protective Coatings

Selecting the right protective coating for cold weather applications involves several considerations:

  • Temperature Range: The coating should be effective within the specific temperature range of the application area. Manufacturers often specify the minimum application temperature and the coating’s operational temperature range.

  • Substrate Compatibility: Choose a coating that is compatible with the material of the substrate, whether it’s metal, concrete, wood, or another material.

  • Environmental Exposure: Consider the environmental conditions the coating must endure, such as exposure to chemicals, UV radiation, or abrasive forces.

  • Application and Curing Conditions: Some coatings are specifically formulated to be applied and cured in cold weather, while others may require certain conditions for effective application.

Application of Cold Weather Protective Coatings

The application of protective coatings in cold weather demands careful planning and execution to ensure optimal performance:

  • Surface Preparation: Proper preparation is critical, as cold weather can affect the surface’s moisture content and cleanliness. Surfaces should be dry and free of ice, frost, and contaminants before application.

  • Heating Strategies: Applying heat to the substrate and the surrounding environment can help maintain the coating and surface within the optimal temperature range for application.

  • Application Techniques: Cold weather can affect the viscosity of coatings, necessitating adjustments to application techniques. Spraying equipment may require modifications or alternative application methods may be chosen.

  • Curing Considerations: Coatings may require extended curing times in cold weather. It’s essential to account for this in project timelines and to protect the coating from adverse conditions during curing.

Critical tips for cold-weather coatings applications:

  1. Keeping products conditioned in cold weather will help with installs. Store and condition products at 65° to 75° F before application. Whenever possible, warm the ambient air by turning up the thermostat in the application area or use radiant heaters to keep the temperature from dropping too low. Warming the surface or substrate with portable heaters, hot air blowers, and/or heat lamps will ensure that the material flows smoothly, creating a strong bond with the substrate.

  2. Applying the right products is crucial. Always look carefully at the coating product data sheet for information about whether the material can be applied in temperatures below 50° F. Consult with the coatings manufacturer’s technical representative to be sure.

Our process

our coating inspection process

We have a tried and true methodology for assessing and prevention corrosion through our ISO-standardized and client-customized workflow.

01.

Survey

A maintenance survey determines the coating conditions of a surface. Surveys are used to create a maintenance schedule for re-coating and touch-up applications.

A coatings survey provides a sense of how a coating is currently performing and identifies any problems that need to be addressed immediately. The survey provides the next steps to be undertaken. Surveys are a necessary part of an ongoing maintenance plan and should be performed on a regular basis.

This is the qualitative test of the adhesion coating system. This test will only give allow to ensure there is an adequate bond to the coated substrate. This test does not differentiate between levels of bonding. Adhesion testing is used to evaluate the adhesion to the substrate, in between coats, and internal film.
