What Are Two Common Winter Taping Mistakes in Canada?

In Canada, construction and remodeling projects in winter pose special difficulties, especially for finishing and taping drywall. Even experienced contractors can have problems when temperatures drop and humidity levels change dramatically between indoor and outdoor environments.

Join us and discover the importance of these problems and how to prevent them during harsh Canadian winters with Common Winter Taping mistakes, avoiding costly repairs and guaranteeing excellent results.

Problems With Temperature-Related Adjustments

One of the most Common Winter Taping mistakes made during Canadian winters is working with joint compounds in environments that are too cold. The chemical processes necessary for proper drying and curing slow down considerably when temperatures drop below 10 °C (50 °F).

The consequences of working in such a cold environment are prolonged drying, uneven setting and the possibility of breakage when the compound finally hardens. Contractors sometimes use fast-setting compounds to compensate for this, but if not handled properly, this could backfire.

Indoor heating systems operating at full capacity during the winter months can also create problems with the setting of the compound. The outer layer of the compound can form a skin too early due to the extreme dry heat, trapping moisture underneath. This can cause bubbles, cracks, or delamination weeks after the project is finished.

Maintaining a constant ambient temperature throughout the curing process is critical to prevent temperature-related setting problems. This involves keeping the work area between 13 °C and 21 °C (55 and 70 °F) and ensuring that there is sufficient ventilation to avoid cold breezes that could affect drying patterns.

Humidity control

The marked difference between indoor and outdoor humidity levels during Canadian winters creates another common issue in the taping of drywall. Heating systems can draw moisture out of the property too quickly, causing the indoor air to become abnormally dry, something that many contractors overlook.

On the other hand, some workers, especially in poorly ventilated areas, make the mistake of not allowing sufficient drying time between coats. Low winter humidity outside, combined with sealed buildings, can form pockets of high moisture content, making proper drying difficult. This often results in moisture retention, which, months after the work is finished, can cause the paint to bubble or the paper tape to come off.

Keep in mind that maintaining humidity levels requires a comprehensive strategy. Important measures include:

• Using humidifiers in very dry places.
• Ensuring that there is sufficient airflow without producing cold areas
• Allowing paint to dry completely between applications.

Most moisture-related problems can be avoided by monitoring the temperature and humidity levels of the project.

Considerations For Long-term Performance

Successful projects require an understanding of how winter taping conditions for drywall can affect long-term performance. Many contractors are only concerned with getting results quickly, without considering how changes in temperature and humidity during installation can affect the durability of their work.

Months after the taping work is completed in winter, seasonal changes can cause stress on the joints and highlight defects. Thermal expansion, humidity variations and building movement caused by freeze-thaw cycles can compromise the integrity of sealed joints. These potential problems are reduced during installation with the use of a proper method and selection of materials.

Long-term success requires looking beyond project completion and considering how environmental factors related to installation can affect the work throughout the life cycle of the building.
