What to Consider When Choosing Concrete Sealers

Applying a sealer to your old or new concrete is always a good move. This is because curing and sealing concrete will help protect, strengthen, and enhance its appearance for the years to come. Knowing which product to choose for your specific project or application is important. Perhaps you have a stamped driveway or an acid stained floor. Either way, read on to know how you can pick the perfect one for your needs.

What Finish Does Your Concrete Have?


There are generally five types of finishes, namely exposed aggregate, smooth trowelled, broom finished, paved, and stamped. Each of these has its own unique considerations when sealing concrete.


Determine what your expectations are for cosmetic appearances and what your personal preferences are. From there, you should be able to tell if a penetrating water repellent or a film-forming concrete floor sealer would be the better choice. The former is often recommended for manmade or natural stone along with smooth troweled, broom finished and paved finishes. Meanwhile, the latter is ideal for most finishes except the smooth troweled one.


Where Will It Be Applied?


Check out where your concrete is and its surroundings. Is it under the grill or a table? Is it underneath many large trees? Is it around your pool deck? Take into consideration the contaminants and elements that the floor will be exposed to before proceeding to concrete sealing.


For surfaces that will be exposed to a lot of UV light, salt, or chlorine, a water-based liquid repellent would be a good choice. When applied correctly, it should be able to last you for 5 years. A high gloss acrylic sealer, on the other hand, would be better for any areas that require superior protection, such as driveways and patios.


How Do You Want It to Look?


Several factors can impact the final look of your application, including penetration, color development, darkening, and gloss level. In many cases, chemical-based sealers can do more for you than water-based ones, though liquid repellents don’t affect the cosmetic appearance whatsoever.


Not all sealers have the same stability when exposed to UV light. Some may turn brown or yellow after prolonged exposure. However, there are many products that contain UV absorbers and stable resins that can delay, if not prevent, yellowing.


Prior to sealing concrete, some versions of colored or stained ones may appear dusty or dull. You might want to achieve a glossy finish or you may prefer to maintain the original appearance of the substrate. Anyway, the choice is up to you and will affect which product you use in the end.


Having expectations on what you want the concrete to be protected from or how you want it to look like will better enable you to pick a sealer you will be happy with for the years to come.
