Did you notice the small pits that collect puddles on your concrete? Does it seem to be crumbling and cracking? The main reason for this is probably because of too much water in the concrete mix used. This is phenomenon is what professionals call as concrete spalling.
Fixing Concrete Spalling
However simple it may sound, concrete spalling is not the easiest DIY fix. If your driveway or parking lot surface is greatly affected by spalling, causing cracks to appear all the way through, only trained professionals are the only ones who you can turn to for help.
But if the damage on the concrete is not too far gone, the repair can still be something that you can do yourself. But take note that it takes extra care and precision when it comes to repairing concrete spalling. You might end up with a not-so-perfect, “good enough” level of quality once you try to do it on your own. A professional can achieve this task well and with the perfect results. In the end, the choice is still up to you, and should you want to take on the job on your own, here are the things that you will need to do:
- Before you start the DIY concrete repair job, you have to make sure that air temperatures remains above 50° eight hours after you pour your concrete, and above 32° for 24 hours right after that. Now, for you to start repairing your concrete, you need to remove all dirt and debris. Use a broom to brush your concrete surface clean of dust and unwanted stuff. And if there are any weeds in the concrete cracks, pull them out and remove weeds on the edges (if there are any).
- It’s very important to pressure wash your concrete next to thoroughly remove the dirt and debris as much as possible. Make sure to work and wash using one direction so the area is cleansed properly. Doing it in different directions will spread some leftover dirt.
- Tape off the areas that you don’t want your new concrete to come in contact with. A good example for this is where your bottom step meets the concrete driveway surface. If you are doing an indoor concrete repair or resurfacing, the bottom three feet of your walls must be taped off.
- Mix your concrete. Make sure to only mix concrete that will only be enough for use in about 20 to 30 minutes. For an average person, this is equivalent to a 40lb bag which cover roughly about 35 square feet. Place the concrete powder in a cement mixer or wheelbarrow and add water from time to time until the concrete’s consistency becomes like that of peanut butter.
- After that, roll on a layer of bonding agent. Be sure to use two trowels, one is for you to lean on with one hand and the other for doing the work. Spread the concrete mixture evenly over the selected surface. This may be the most complicated part of the concrete repair process, and the skills of professionals like us can definitely make a noticeable difference. This step should be handled with precision and care. While you spread the mixture, make sure to use any leftover concrete mix to fill in holes.
- Before the first coat dries, add a second coat immediately in the same way as you applied the first one. The second coat is responsible for giving your concrete surface an attractive and finished look. You can achieve this by applying a concrete stain or having a design on it using stamped concrete. For this layer, a peanut butter consistency is not needed. You’ll need something that is wet, similar to a pancake batter.
- Before applying the second coat, you have to test out the mixture to be sure that it’s of the right consistency. If little balls form once you apply it, the concrete is too dry. Spray a little water to dampen the first coat.
- For the final touch, drag your second coat across the entire surface using a concrete broom. If necessary, spray water.
