How To Fill Concrete Cracks

Concrete, whether it is a wall, housing foundation, or driveway, is going to crack overtime.This is inevitable, and it is usually caused by the shifting of the soil underneath. Small cracks, which are usually just cosmetic, don't pose any structural problems to your concrete slab, but you probably still want to fix them immediately because they are unsightly. This article explains what supplies you need and the best steps for properly filling cosmetic concrete cracks.

Don't Use Concrete Mix

First off, is important to know that you shouldn't fill small cracks with actual concrete mix. Some people mistakenly think that they can just use ready-mix concrete. Even if you have the same exact concrete that is currently on your driveway, using it in a small crack or hole will not create an effective patch. In such a small area, the new concrete will not be very strong and it will have different consistency then the original slab. In the end, it just won't last as long as an actual concrete crack filler. Concrete crack filler is pretty much the same thing as concrete mix except it is premixed and it has heavy-duty glue mixed in. This means it will hold in even the tiniest crack.

The Simple Process is Simple

The process of filling the crack is simple. You just want to fill in the crack as tightly as possible. Squeeze or spread the filler into the crack using a party knife. Scrape it and push it down, making sure it fills in the entire crack, all the way to the bottom. You don't want there to be any cavities underneath the crack filler. You also don't want the crack filler to be thin and just covering the top of the crack. You can usually scrape away the excess filler to create a flat, seamless transition. However, the textures might vary, depending on whether or not you are polished or raw concrete. So, after the crack filler is completely dry, you might need to use some sandpaper to smooth it out.

Filling concrete cracks is very simple and cheap. You can pick up supplies at any home improvement store and use tools you already have in your toolbox. It is a great DIY project to learn. Once you figure out the process, you can fill and repair cracks in any concrete surface around your house. It is a cheap and easy DIY project, even for those who aren't particularly handy.
