Q: When is the best time to pour concrete?

• <div><p>The best time to pour concrete is mid-afternoon when temperatures often sit between 50 and 60 degrees, and you don&rsquo;t expect rain for at least 24 to 48 hours. Avoiding direct sunlight in the peak afternoon hours can help reduce the risk of curing too quickly, as can avoiding pouring on hot summer days. Colder temperatures and rain can lead to slower curing times and weaken the concrete. If in doubt, especially if your concrete will provide structural stability, <a href="https://www.angi.com/articles/how-to-hire-a-concrete-contractor.htm">hire a contractor</a> to determine the best time to pour.</p></div>

Q: Can a concrete patio be too thick?

• <div><p>In most cases, you&rsquo;ll want your patio to be 4 inches thick, although you should add reinforcement and increase the thickness up to around 8 inches if you want it to support heavier loads and resist cracking more readily. Although thicker slabs will cost more, you&rsquo;ll start seeing diminishing returns at around 6 inches.</p></div>

Q: Is it better to stain or paint concrete?

• <div><p>Generally speaking, stain is a better option for concrete because it soaks into the surface and won&rsquo;t get worn away like a topical paint will. Painting concrete increases the risk that moisture will get trapped beneath the top layer of paint, which wears concrete down over time. So long as you know how to prep concrete for staining, you'll maintain its strength after you finish your project.</p></div>

Q: Should I use mortar or concrete for a chimney crown?

• <div><p>You should use cement for a chimney crown. The purpose of the chimney crown is to protect the mortar below from water damage and the effects of weather. For this reason, chimney crowns should only be made using cement. When repairing a crown, use caulks and sealants designed for cement repair rather than mortar repair.</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>

"I spent a lot of time trying to find someone that could replace my front steps. Getting someone to actually call back was the first challenge. Then, trying to find someone who does everything we wanted: granite steps, faux stone facing and sides, white railings, and the ability to tear up and lower my walkway then redo it to make the first step 7” was an even bigger challenge. We finally found the right guy/company and we are very happy with the results. Walter Santos of W. Santos Construction did it all for us. He started within days of us accepting his proposal. He was kind, communicated the next steps with us well, and the quality was fantastic. I was outside tonight taking photos and a family was taking a walk stopped me to ask who did the steps because “they make the house.” I took some dry and wet pics after the dust was washed off and I’m very happy with the results. He even came out to finish on Memorial Day."
