Summer is officially here, and that means one thing: hot weather is on its way! If you have a concrete driveway, patio, or any other concrete surface on your property, it’s important to take steps to protect it from the damaging effects of the sun and heat. Properly sealing your concrete will help keep it looking new for years to come. When it comes to hot temperatures and sealants, there are three main issues that can arise: resin strings, blisters and diffusion. All of these problems can be prevented by taking the proper precautions and using the right products. In this blog post, we will discuss how to seal concrete and the benefits of doing so as well as how to deal with these three pesky issues that may arise as the temperatures rise!
Resin strings are commonly caused by low-quality sealants that contain too much resin. When this type of sealant is exposed to heat, the excess resin can flow out of the surface and form string-like formations that sag or drip, making it difficult to apply evenly. This can also make it more difficult to remove in the future as it may cause blisters or bubbles. A few ways to prevent this from happening is to apply a thin coat of a resin-based sealant in an area that is well ventilated and in cooler temperatures. Most importantly, ensuring it is completely dry before exposure to hot temperatures. For this we recommend 2 thin coats of sealer to the concrete. The best approach we always recommend is “ 2 coats thin to win! ”
Blisters are caused by trapped air bubbles that form under the sealant. This can happen if the sealant is applied too thickly or when it is applied in hot weather. The heat causes the sealant to expand and form bubbles, which can eventually burst and leave behind unsightly marks. To avoid this, it is best to ensure the surface is clean, and dry. Also, applying the sealant in cool or shady conditions, and making sure it has plenty of time to dry before exposing it to direct sunlight. For this we recommend using Innovative Manufacturing’s ‘Resolve’ to help correct any blistering, bubbles or any moisture that is trapped between the concrete sealer and concrete surface!
Another common issue that can occur when sealing concrete in hot weather is diffusion. Here, the sealant loses its colour and becomes translucent. This happens when the heat causes the sealant to vaporize, which can cause it to lose its bonding properties. It is important to note that this can occur days or even months after application. For this reason, it is necessary to take appropriate precautions before applying sealers. To avoid diffusion, make sure to apply the sealant in cooler temperatures and allow it to dry completely before exposure to heat. For this we recommend to seal your concrete below 25 degrees. You can always seal your concrete in the morning while temperatures are cooler, but please be wary of moisture from the night before.
While sealer manufacturers go to great lengths to ensure their products will perform well in all types of weather, there are still some things that are beyond their control. That’s why it’s important to avoid applying sealers while temperatures are about 25 degrees or when the wind is blowing. To prevent this, it is important to follow all manufacturers instructions carefully and allow the concrete to cure completely before applying the sealant. Ultimately, the more you can learn about the products you are using, the better off you will be.
As summer temperatures start to rise, it’s important to be aware of the potential problems that can come along with them. Hot weather can cause all sorts of issues, from cracking and flaking to deterioration. Specifically, when it comes to concrete sealant, prevention is key. By regularly inspecting your sealant and making repairs as needed, you can avoid serious problems down the road and you’ll be able to keep your concrete looking its best for years to come! Don’t wait until there’s a problem to take action. Inspect your sealant regularly and make repairs as needed to keep it in good condition. Your concrete will thank you for it!
