The cost of concrete repair can mount up if you fail to fix small cracks. That is, if you leave your concrete unattended, the damage and corrosion is bound to become more severe and more costly to repair as the crack grows. This article explains how to fix small concrete cracks.
The Best Tools and Supplies for the Project
When it comes to concrete preservation, it is all about taking preventative measures and fixing small cracks as soon as you see them. The most important thing you need for the job is a premixed crack filler. Make sure you buy a filler that is intended for concrete, and not asphalt. You can find crack filler in caulk form and in larger premixed tubs. The caulk filler is convenient because you can easily squeeze it into narrow cracks. However, it is not the most cost-effective way to buy crack filler. The tubs are more convenient if you have larger holes and cracks that need to be filled. They aren't quite as convenient because you need to use a trial or float to apply the filler onto your concrete. It is a good idea to buy these materials and keep them on hand to make running repairs as needed.
Preparing and Filling the Crack
Applying the crack filler is often the easiest part of the job. However, preparing the crack to actually be filled can be a little bit difficult. First of all, you need to clear out any weeds or grass growing out of the crack. Then, you need to smooth out the inside of the crack so the depth is even. That is, if the crack is only 1/8" deep, the crack filler will be too thin and weak when it dries. You should also clean the top of the concrete, particularly next to the cracked areas. You will need to spread some of the crack filler onto the flat surface and taper it down to create a smooth transition between both sides of the crack. A small putty knife is the best tool for creating a flat and smooth patch. You should also keep an eye on the crack filler as it dries because it can sink as it settles. If this happens, just add some more filler.
The final step is to seal your concrete slab with sealant. This waterproofs and protects the concrete in the long run. And is important, especially for sealing the crack filler. For more information, visit websites like http://www.starpaving.com.
