Q: Can you grind concrete by hand?

• <div><p>Yes, you can grind concrete by hand, but it&rsquo;s typically known as sanding concrete when done with a hand grinder. Additionally, you should only use this method if you&rsquo;re working on a smaller area, like a countertop, rounding an edge, removing imperfections, or doing a spot repair versus a driveway or patio.</p></div>

Q: How to dry concrete quickly?

• <div><p>Use a dehumidifier for indoor concrete and a wet vacuum for outdoor surfaces. Sprinkle absorbent materials like sawdust or cat litter to soak up the remaining moisture. If the concrete is outside, simply wait for a few hot, dry days. If the concrete is inside, make sure you have good ventilation for a few days so that any remaining moisture can completely dry out.</p></div>

Q: Can you pour concrete over old concrete?

• <div><p>Yes, you can pour new concrete over old concrete, but you need to apply a concrete bonding agent to the existing concrete to ensure the new concrete sticks. Keep in mind that even with a bonding agent, large cracks and other flaws will still come through. If the concrete has heaved, settled, or cracked, pouring new concrete on top won&rsquo;t address any root structural problems. Removing the existing concrete and rebuilding will be your best solution in that case.</p></div>

Q: Should you wet concrete before jackhammering?

• <div><p>Yes, you should always wet concrete before jackhammering to avoid harmful dust from becoming airborne. According to the U.S. Occupational Safety and Health Administration, they recommend a wet-cut method that involves continuous spraying of the concrete where the jackhammer bit hits. Use a jackhammer with a built-in sprayer attachment, or have a work partner spray the area with a garden hose and spray nozzle.</p></div>

Q: How long does dry pour concrete take to cure?

• <div><p>Dry pour concrete cures in the same amount of time as wet pour concrete, so you&rsquo;re looking at four to six hours for it to harden, 24 to 48 hours before you can remove forms and expose the slab to foot traffic, a week before it can stand up to vehicle traffic, and about a month for it to be fully cured. </p></div>
