All concrete sealers are considered all weather concrete sealers, but depending on the amount of exposure to the elements, and how hard the sealer needs to work, exposure to the elements can dramatically reduce life and performance over time,
All Weather Water Repellent Concrete Sealers
Water repellent sealers are the most resistant sealers to weather because they chemically react to form a hydrophobic barrier below the surface. They don’t leave a visible surface film or coating, therefore they can’t be broken down by surface abrasion, foot or vehicle traffic, or weather. They will provide the longest life compared to any other type of sealer or coating.
Now, silicate sealers do outlast water repellent sealers because they chemically react to form a permanent CSH structure within the pores. Silicate sealers however should only be used to increase the strength and density of the concrete. They do not offer any water repellency benefits and offer minimal protection against damage and deterioration caused by water absorption.
The downfall to any type of penetrating sealer is that they don’t leave behind a protective surface film. The surface of the concrete is left exposed to the elements and crack break down from exposure to the elements, surface traction, and vehicle traffic. They are a great sealer for reducing damage and deterioration, but if you need something to take surface abrasion, a coating is a better option.
All Weather Acrylic Concrete Sealers
Acrylic sealers are great because they leave behind a visible surface film. If you are experiencing damage, deterioration, or staining from exposure to the weather, surface traction, or vehicle traffic, acrylic sealers are designed to take the abuse so that the surface of the concrete doesn’t. The downfall to acrylic sealers however is that the harder the acrylic sealer needs to work, the faster it breaks down. Depending on where you live, you may find acrylic sealers need to be re-applied as often as every year, or in extreme cases, every season. Things that break down acrylic sealers are extreme temperatures (high and low), exposure to large amounts of snow, ice or water, and high amounts of foot or vehicle traffic. Choosing a high quality sealer will provide the most amount of life possible with a sealer, but the harder the sealer needs to work, the faster it will break down. The best way to determine how a particular sealer will hold up in your application is to apply the product to a test area and see how it performs.
