Concrete is a very durable, affordable, and aesthetically pleasing material. These benefits make it perfect for use in residential driveways, patios, and a variety of other applications. However, in order to get the most out of your concrete surfaces, you may wish to consider sealing these surfaces with a concrete coating. If you are not familiar with this process or are not sure if concrete sealing is right for your needs, taking the time to review the frequently asked questions outlined below can help to ensure you get the answers you need to make the best decision regarding the sealing of all your concrete surfaces.
Does All Concrete Need to Be Sealed?
It is often recommended that all exterior concrete surfaces be sealed once the concrete has fully cured. However, this is most important in areas that experience a freeze-thaw cycle during the winter months. This is because moisture that seeps into the concrete can freeze when temperatures drop low enough. Since water expands as it freezes, this freezing process can cause significant damage to the concrete surface. The use of deicing salts on unsealed concrete surfaces can also result in damage. This is yet another reason why it is so important to seal the concrete surfaces around your home if you live in an area that experiences freezing temperatures.
Will a Concrete Seal Last Forever?
Unfortunately, like most sealants a concrete coating will wear off over time. The good news is, these sealing products will often last several years before needing to be reapplied.
What Happens If Concrete Is Not Sealed?
Damage resulting from freezing temperatures is just one of the types of damage that can occur as the result of leaving your concrete unsealed. This is because the porous nature of concrete leaves this building material susceptible to a variety of moisture related damage. For instance, if your concrete is exposed to motor oil, fertilizer, cleaners, or other common household chemicals, the surface of your concrete can become stained or cracked. For this reason it is often recommended that you seal your concrete even if you do not live in a cold weather region.
Will a Coating Change the Look or Feel of Concrete?
The answer to this question will depend upon your choice in sealants. While some sealants are designed to alter the way your concrete looks by providing a shiny top layer, other sealing products will preserve the original look and feel of your concrete surface. If you are hoping to achieve a specific look, it is best to discuss all of your options with an experienced concrete contractor before deciding on which type of sealant to apply.
