There are different concrete sealers for different applications, so it is important to know which one is right for your project.
For instance, a decorative concrete project like a stamped patio requires a sealer that protects it from moisture and guards it against abrasion that could diminish coloration. A film-forming acrylic sealer is perfect and will also bring out the color, depth and vibrancy of the concrete.
On the other hand, a traditional broom-finished surface, like a driveway, needs only protection from moisture and perhaps salt that can take a toll on concrete during winter months. The best available technology for traditional, or what many call “plain concrete,” is penetrating sealers such as silanes and siloxanes. These sealers are invisible at the surface and work within the concrete to block moisture.
Acrylic sealers are effective for one to three years depending on the type of use and the degree of UV exposure.
Penetrating sealers are effective for a much longer period, often lasting up to ten years. There have been studies on bridge decks that have shown some degree of protection in ranges approaching fifteen years.

How to Fix a Driveway
Acrylic sealer is useful as a concrete restoration product if we consider a worn decorative surface that needs an enhancement. It can lock-in any new color added, and it can also be tinted with color for a new and fresh look.
Penetrating sealers do not enhance any surface. These products are simply designed to reduce moisture and salt intrusion in an effort to minimize damage caused by extreme environments. Penetrating sealers are used on concrete that is currently in good condition as a maintenance treatment. It helps it look as good as it can for as long as it can. They are used to extend service life.
Fixing a concrete driveway could mean many different things:
- Problems often occur from shifting soils underneath it
- Expansive clay soils could shrink when dry and heave the concrete upward when wet.
- Sections may begin to move around independently and joints become wider or slabs become uneven.
- Blemishes at the surface may appear, such as scaling, spalling, and aggregate pop-outs.
- Peeling and delamination issues could occur.
The best advice we can give for any concrete project is to use the best practices as defined by the American Concrete Institute, the Portland Cement Association, local building code enforcement agencies, and others. This includes sealing concrete at the beginning to extend its life. You can’t fix cracks with a sealer.
And remember, concrete performs best when you can find ways to keep water away from it, off of it, and out of it.
