If there is one home improvement product that rightfully went viral for its amazing ability to seemingly fix up everything in sight. Even driveways are said to be fixable by Flex Seal. Even though the reputation of Flex Seal is sterling, it’s still important to know what it can and cannot do for you.

Flex Seal can be used to seal small cracks in asphalt, but if you want to get the best results possible, try out Flex-A-Fill. Flex-A-Fill is a handy new concrete and asphalt filler, and it’s literally designed for this purpose.

Having the right type of Flex Seal is important to making sure that you get the most out of your driveway’s health. Before you decide to go onto the Flex Seal site for your tube of goo, make sure that you know which one you should get.

Is Flex Seal Good For Cracks In Asphalt?

It is, actually! Regular ol’ Flex Seal is great if your asphalt recently cracked. To use standard Flex Seal, it’s pretty easy. Here’s what you will have to do:

  • Pick your Flex Seal color. Most go with clear, but you can also get black or grey for most driveways. If you have a colored asphalt driveway, you *might* be able to find a shade that fits.
  • Clean out the cracks of your asphalt and the surrounding area. You don’t need to go crazy, but wiping the area down with some soapy water can help.
  • Apply the Flex Seal to the cracks, making a point of funneling it into the cracked portion of your driveway. If you can pipe it in, great! That’s actually the best way to do it. Otherwise, you can probably apply it with a brush.
  • Even out the Flex Seal. A lot of people will use a trowel or putty knife to touch things up, but once again, this is not entirely necessary unless you really globbed it on by accident. After all, Flex Seal is notoriously self-leveling.
  • Let the Flex Seal cure. Just like that, you’re done. It usually will take 48 hours to fully cure. During this time, it’s best not to expose it to water and to avoid driving on the pavement.

What’s The Best Flex Seal Product For Cracks?

All Flex Seal products are great, but recently, there is a better product that is specially made for crack sealing in asphalt and concrete. It’s called Flex-A-Fill, and all you need to do to use it is follow the directions on the product’s packaging. It does require using hot application, but it is much more durable.

Can You Use White Flex Seal For Asphalt Cracks?

You can, but it might look a little funky on black asphalt. Since it’s white, it will have a massive contrast that most HOAs will probably hate. It’s not unheard of for people to get written up by HOAs as a result of using white Flex Seal for asphalt cracks.

How Long Does Flex Seal Last On A Driveway?

While there are some variations in the total time length, most people will find that you can expect it to last a total of two years. In some cases, it may last up to 36 months, but this is not the norm. Moreover, you still have to seal your driveway (with regular asphalt sealant) every two to three years to make this work.

Is Flex Seal The Best Crack Filler For Driveways?

It seems to be very popular, that’s for sure! Whether it’s the best and most long-lasting crack filler, though, is up for debate. Many people seem to be perfectly satisfied with it. We at Upgraded Home love the stuff, so we’re all about it!

However, we need to keep things balanced. Others seem to feel like using a formula that’s specific for filling asphalt driveway cracks, like Dec O’ Seal.

How Big Of A Crack Can You Fix With Flex Seal?

While Flex Seal is great, it’s not a panacea for cracks. It’s going to have its limits and it’s important to know when you may need professional asphalt repair. Most of the time, Flex Seal is only good for cracks that are between 1/4 inch and 1/8 inch in width.

Any larger, and it won’t make sense to use Flex Seal. The Flex Seal won’t be able to hold the driveway’s two sides together and it may end up tearing when a car drives over it. Besides, if you have cracks that big, repaving might just be the better option both long- and short-term.

Can you seal a cracked driveway?

If you absolutely have to seal a driveway without fixing the cracks, you can. However, it’s not good form and it may make your seal last a shorter period of time.

Is Flex-A-Fill made by the same company as Flex Seal?

Flex Seal is one of the most popular product brands of its kind, but don’t be fooled by the “Flex” part of Flex-A-Fill. While most assume that Flex-A-Fill products are made by the same people as Flex Seal, it’s not true. Flex Seal is made by the Swift Response corporation. Flex-A-Fill is made by CrafCo Preservation Products.Though you might think of one as the knockoff of the other, the truth is that it’s not a normal comparison. Flex Seal is used for a wide range of different things, including asphalt and pools. It’s cold-applied. Flex-A-Fill is almost exclusive to asphalt and requires hot application to cure.

Can you use Flex Seal Spray on a driveway crack?

Flex Seal Spray is great on a variety of materials, but it won’t do much for a crack in your asphalt. As a result, we don’t recommend using it. The best Flex Seal products will be gel-based and thicker in consistency. This is the best way to ensure that your crack gets fully filled.
