Why does concrete crack?
Cause #2: Shrinkage of the concrete. All concrete shrinks when it transitions from plastic (liquid) to a solid state as it sets up and hardens. As it shrinks, cracks form regularly… transverse to the long edge. To understand this think of a typical sidewalk. It has grooved joints every 4 or 5 feet. These joints are places for the concrete to crack as it shrinks. We don’t typically put crack control joints in stem walls, since the rebar tends to help reduce (but not eliminate) shrinkage cracks.

If you are ready to get a smooth finished wall without annoying cracks, it’s super easy! Just follow along and do the steps with Ken. The great part is that this DIY project only takes minutes and is super easy.
1. Prepare the area
Most cracks occur around thresholds and doors. Since we will be painting, it’s better to be safe than sorry! Just grab some painter’s tape and make sure you cover the exposed areas around the door that you don’t want to be painted.
2. Open up the working surface
This might be the most fun part! In order to have better access to the crack, we are going to open it up a bit. The best way to do this is to grab an old screwdriver and just pull the tip through the drywall, scoring and widening the crack. After you widen it, just use a damp cloth to clean it.
3. Apply fiberglass tape
We want to make sure the issue doesn’t come back! Using self-adhesive fiberglass tape, simply put a strip that covers the area well. This is going to make sure it stays reinforced and doesn’t become a repeat problem.
4. Apply drywall joint compound
This sounds fancy, but it really isn’t. Just spread out some compound onto the area to fill in the spaces. Using some pressure and a paint knife, press the compound into the area. After it has time to dry, scrape off any bumps with a pass or two of the knife. When the first coat is smooth, add a second coat in the same way.
5. Scrape and sand
We are almost done! Using the painting knife, make sure there are no rough spots in the compound with a pass or two. After that, take your sander of choice (a wood block with 100 grit sand or Ken’s preferred choice of a specialized drywall tool works). Go over the area and make sure it’s super smooth.
