Why Should You Apply Concrete Sealing at the Right Temperature?

26 April 2023

Many processes may help protect concrete surfaces from damage. However, one effective process that can provide optimum protection to concrete surfaces is concrete sealing.

Concrete sealing is a critical step in protecting concrete surfaces from wear and tear, exposure to the elements, and staining. However, applying concrete sealer at the wrong temperature can result in improper curing, deterring the sealer from bonding properly with the concrete surface.

Concrete Sealing at the Right Temperature is a Must

There are many reasons why you should apply concrete sealing at the right temperature.

The first reason why the right temperature is essential when sealing your concrete is that temperature affects the curing process. Sealer requires a specific range of temperature to cure properly. Upon following the manufacturer’s instructions closely, it can easily ensure that the curing process is successful. Sealing your concrete when the temperature is too high or too low can cause the sealer to dry too quickly or too slowly, resulting in a weak bond. Doing this can also reduce the lifespan of your applied sealer.

Another reason why the right temperature is important when sealing concrete is that temperature affects the adhesion of the sealer to the concrete surface. The right temperature ensures that the sealer will bond properly with your concrete surface, creating a protective barrier that can withstand exposure to the elements, such as rain and sunlight. When applied at the right temperature, the sealer can infiltrate your concrete surface and bond effectively, resulting in a durable and long-lasting seal.

Additionally, the right temperature can affect the appearance of the sealer on your concrete surface. Applying sealer at the wrong temperature can cause the sealer to look blotchy or uneven, affecting the overall appearance of your concrete surface. If the temperature is too low, for example, the sealer may not spread evenly, which can result in visible streaks or areas where the sealer is thicker than in other areas.

Ultimately, temperature also affects the working time of the sealer. If the temperature is too high, the sealer will dry more quickly, reducing the time available for working with the sealer. Conversely, if the temperature is too low, the sealer may not spread as easily, making it more difficult to achieve an even coat. It can eventually result in the need for additional coats, which can increase the needed time and cost of your project.

Key Notes to Remember when Sealing the Concrete

When sealing concrete, you should follow the manufacturer’s instructions regarding the recommended temperature range for the sealer. Typically, the ideal temperature range for applying sealer is between 10 and 27 degrees Celsius. This temperature range ensures that the sealer will cure and bond effectively, which can result in a long-lasting and durable seal.

The temperature of your concrete surface should also be taken into consideration when applying sealer. If the surface is too hot or too cold, it can affect the performance of the sealer. To ensure that the surface temperature is within the recommended range, you must wait until the weather conditions are favourable. You can also use external temperature control measures like shade or heat lamps to regulate the temperature.

Applying concrete sealing at the right temperature is crucial for achieving a durable and effective result. After all, temperature affects the curing process, adhesion, appearance, and working time of the sealer.
