Cracks in your concrete are annoying and unsightly. They can also become trip hazards and compromise the integrity of the concrete slab. This is why you obviously want to repair cracks as soon as possible. When left alone, the cracks will just get bigger and bigger. The best product for filling small concrete cracks is premixed liquid crack filler. This is easy to use because you don't need to mix it and you can pour it right into the crack. This article explains how to use concrete crack filler.
Getting the Right Product
First, you need to color match the concrete. If you have a color or tinted concrete, you can buy mix-ins to try and match. This often takes a little bit of trial and error. You might have to apply a small section of crack filler onto the concrete. Wait for it to dry and check the color to see how good the match it. Once you have the right color, you can prepare the crack to be patched.
Prepping the Crack
To fully prep the crack, you need to sweep the area around the crack. However, you also need to clean out the inside of the crack. You will get the best results if you use a hose vacuum to suck all the dirt out. You should do the vacuuming right before you actually patch the crack so dirt does not blow into it.
Patching the Crack
The key to patching the crack is taping off a path around the crack. You can place the tape 6" to 12" on each side of the crack. This helps to control the filler, but also creates nicer, more aesthetic lines when it dries. Once it is taped off, pour the liquid directly into the crack until it overflows a bit. You need to use a squeegee to spread the overflowed filler. Spread around the filler and blend it in with the concrete. You should try to taper it off as it nears the tape line. You don't want any edges to form when it dries.
When the concrete is dry, you should apply a sealant. You can pout liquid sealant directly onto the concrete and spread it around with the squeegee. This protects the filler, but also helps it to blend in with the old concrete.
This job is very simple, so you should patch any cracks as soon as possible. The longer you wait, the harder it will become. Contact a business, such as D & R Masonry Restoration, Inc., for more information.Share
