Sealing Stamped & Decorative Concrete
What sealant should I use?
It all depends on the finish and effects you want. The sealant you buy can change the look of your concrete surface, so it’s important to pay attention to the finish the sealant provides, whether it’s a glossy finish or matte. Some sealants even have additives that can provide different benefits, including slip resistance.
If cost is an issue, it’s best to get a clear water-based sealant. Not only is it one of the more affordable options, but it’s also non-yellowing, has a low odor and creates a natural look for your concrete surface. If you’re willing to splurge, you could also try using a solvent-based acrylic sealant to create a wet look or a water-based elastomeric sealant to improve your surface’s durability.
If you’re resealing the surface, you need to use a sealant that matches the initial sealant. Using a completely different sealant material will cause it not to adhere to the original sealer, which creates a major mess. Most decorative concrete surfaces typically use a solvent-based sealant, but if it’s a newer surface, you or your contractor might’ve used a water or acetone-based sealant.
When should I seal my concrete?
You should seal your concrete surface regularly. Most people don’t realize that even if you sealed it right after application, it needs to be resealed. It’s best to seal your concrete every two years or when you notice the color starting to fade. That way, you can keep your concrete surface in top shape without washing sealant by over-applying it.
When choosing a time of the day to seal your concrete, it’s best to do it during the summer either during the morning or the evening. That way, it’s not too hot or too cold (60-70 degrees Fahrenheit is the ideal temperature for concrete sealing projects), so the temperature won’t mess with your sealant’s formula. You should also work on it on a day that isn’t raining or snowing because getting rain on the sealant can cause it to look cloudy when finished.
Do I need to hire a contractor?
Sealing concrete surfaces is a simple enough task that you should be able to complete it on your own (and it’s usually cheaper). However, if you’d like your project to be completed by an experienced professional, it helps to hire someone to finish the project for you so you can ensure it’s done right the first time with no mess or hassle. A contractor might also have access to discounted concrete sealant, which can help you save money on supplies.
How much will it cost to seal my concrete surface?
There’s no set price for sealing concrete. What it will ultimately cost you depends on many different factors, including what sealant you purchase, how large your surface is, whether you hire a contractor or do it yourself, where you’re located and more.
Should I wash the surface before sealing it?
Yes! You need to make sure your concrete surface is free of contaminants before you seal it. Before you get started, wash your concrete surface with a pressure washer, making sure to hold the tip of the hose one foot off of the ground so you don’t gouge the surface. Afterwards, use a stiff bristled broom and mild cleaner to get hard-to-reach spots to ensure your surface is completely clean. Make sure the surface, including the saw cuts, is clean before you start sealing. You can speed up the drying process by using a leaf blower over the entire surface.
How can I seal my surface?
There are three easy ways you can seal your concrete surface:
- You can spray your surface with sealant using a special sealer sprayer by moving the sprayer wand in back and forth motions for an even coating
- You can use a paint roller by dipping it into the sealant and rolling it over the surface
- You can spray the surface and then use a roller to evenly apply the sealant
