Concrete that is textured to look like brickwork, tile, slate, wood, or any other number of surfaces is known as stamped concrete and is usually seen on sidewalks, pool decks, and patios. To best preserve its appearance, it is best to seal the concrete with the best stamped concrete sealer that you can get your hands on.
The stamped concrete sealer not only protects the look and feel of the concrete’s surface but also revive its original look. Sealing stamped concrete comes with other benefits such as locking out moisture; minimizing thaw damage; preventing the fading of the color caused by ultraviolet rays; providing protection from stains, chemicals, and deicing salts; and in some cases, even improving the appearance. In addition, re-sealing stamped concrete also makes it easy to clean and maintain the surface and also adds sheen to it.
For a stamped concrete surface, the main type of concrete sealer used is either a solvent- or water-based acrylic. The reason for this is that acrylic sealers allow moisture in the slab to escape and hence, making the stamped concrete sealer breathable. it is also economical and easy to apply. They do not turn yellow easily and are resistant to ultraviolet rays.
With these type of concrete sealer, there are lesser chances of the stamped concrete sealer turning milky or white, and you can be assured that it will perform better when used outdoors compared to other water-based concrete sealers.
But before you buy a concrete sealer, you need to know if that particular concrete sealer is indeed appropriate for your home project. These are the questions you should be asking yourself to help you decide:
The last question is the most important: Why seal stamped concrete? To the untrained eye, the surface looks fine, save for some wear and tear. The answer is simply this — you need to protect your investment.
Sealing is recommended if the new concrete in your driveway has cured or whether it has been a few years since you put in the concrete. You can tell that stamped concrete has been sealed due to its glossy sheen. If it looks faded and old, you may want to know how to reseal stamped concrete to make it look new again.
Furthermore, your stamped concrete surface will be exposed to all kinds of elements such as leaves, dirt, fertilizer, pet urine, and chlorine salts. The right type of concrete sealer will keep these elements off, stop them from penetrating the surface, and prevent ugly stains. If your house is located in an area with colder climates, the chances of freeze-thaw damage will be reduced if the concrete is sealed. Freeze-thaw damage happens when the water that has been absorbed by the surface first freezes, and then expands, causing cracks in the surface.
What the concrete sealer does in this case is stop the water from penetrating the surface, causing it to bead up. If you do not see beads on the concrete surface, you might want to seal your stamped concrete again. You also need to re-seal surfaces which see a lot of heavy traffic.
One way to ensure your stamped concrete always look great is to reseal it every few years. Normally, as a final step, contractors seal the stamped concrete after installation. But we cannot stress enough that resealing concrete regularly is important. Here is a step-by-step guide on how to seal (or reseal) stamped concrete and keep it in great condition for a longer period.
Before you seal the area, clear the area of junk and store them somewhere else in the meantime. Moving around these items while you seal the area can ruin the output of your work no matter how good the concrete sealer is.
Before you start putting the concrete sealer on the stamped concrete, it needs to be cleaned thoroughly. It needs to be free of any contaminants such as spilled oil, grease, dirt, paint, or waxes before you seal the area.
You can use a garden or a power hose to clean the surface thoroughly and use a mild detergent and a brush to clean the dirt off from the corners. Make sure that all the soap is washed away. If you are using an industrial cleaning product, read the instructions on the label and follow them carefully.
After giving the concrete surface a thorough wash, it is important that you let it dry completely. This takes about 24 hours or more, depending on the weather condition. If you put concrete sealer on a wet or damp surface, a “blushing” effect occurs. This happens because moisture is trapped inside the concrete sealer, giving it a cloudy, undesirable look.
Before you seal the surface, you must divide the area into smaller parts. This will ensure that you seal and cover the area thoroughly. There are two ways you can apply the concrete sealer to the surface: a brush or a paint roller.
If you are using a roller to seal the surface, you will still need to use the brush beforehand, because the roller cannot reach the corners. Also, while you seal the surface, make sure that the brush edges do not go dry at any point and blend in with the next stroke. You will need to pay attention because if you do not, it may lead to a visible, uneven patch that will look ugly.
It is important that you let the concrete floor dry for at least 24 hours. Read the instructions on the concrete sealer’s package to find out how long you should wait. If it is an area where you drive on, you will need to give it at least three days to seal completely.
While sealing the stamped concrete may seem like a pretty straightforward procedure, there are some common mistakes that you should avoid.
Regular upkeep of your sealed surfaces will not only help maintain the look but also add value to your property. You can put these extra layers on your stamped concrete now to save on repairs later. Adding anti-skid to the sealer is a good idea because it will prevent the floor concrete from being too slippery when wet.
Remember that concrete can take a lot of abuse but it can be tough to repair if it is chipped or broken. If you follow the advice and the procedure in this article, you can enjoy the craftsmanship of your stamped concrete for many years to come.
