How to Repair Basement Concrete Cracks?

Answer 1

Sometimes, you might have concrete in your basement. Sometimes, you might find yourself going into the basement and noticing that you have cracks in the concrete. Though this might seem like something you should worry about, it is a painless and simple process to fill and seal the cracking you find in the basement concrete. These easy steps will get you through the process of sealing the cracks, getting the task off your to-do list and to get your mind off of the worry.

1. Take a screwdriver and use it to dislodge any debris that might have found its way into the cracks of the concrete. To thoroughly clean out the cracks, take an air compressor and blow out any small particles.
2. Get yourself some pre-caulking spray and apply it generously over all of the cracks that you see. You should ensure that you spray enough so that there is at least a full inch around every crack that you see in the concrete.
3. Fill in every last crack in the concrete using a metal spreader and your everyday standard caulking for cement. There is an effective way to doing this, and there is a correct way, as well. Take a large amount of caulking and put it onto the top of the crack, spreading it down as you see fit.
4. There will probably be at least a little bit of excess caulking lying about, and you will want to get rid of this before it dries and hardens. Try to scrape it off, using the metal spreader, in a way that makes the transition as smooth as you can possibly make it.
5. Let an hour go by for the caulk to dry. When the caulking is nearly the same color as the concrete, it will be safe to continue.
6. Get a sheet or a pad of sandpaper, heavy grade, and use plenty of pressure to sand down the caulking so that it is perfectly level to the concrete. You should expect for this step to take awhile since, during drying, the caulking has expanded.
7. Get a concrete sealant and evenly and thinly coat the surface that was cracked.
