How do you remove penetrating sealer from concrete?

• <div><p>Penetrating sealer seeps into concrete pores to protect it from moisture and staining, cracking, and mold caused by water. This means you cannot remove penetrating sealers like topical sealers. The good news is that penetrating sealant doesn’t have to be removed before resealing, as most topical sealers must. Instead, you’ll want to buy a compatible penetrating sealant (often the same kind already in the concrete) and apply it. Always follow the manufacturer’s instructions.</p></div>

How much does it cost to replace concrete?

• <div><p>The average cost to replace concrete depends on the amount of material you need. However, you can expect the cost of replacing a concrete driveway to range from <b>$2,000 to $7,000</b>, or about <b>$15 per square foot</b>.</p><p>If you want to install or replace a concrete patio, the cost ranges from <b>$800 to $9,000</b>, depending on the size and exact materials. If you only need a slab, concrete slab costs range from <b>$4 to $8 per square foot</b>, or an average of <b>$5,400</b>.</p></div>

Q: How long does a resurfaced concrete driveway last?

• <div><p>Resurfaced concrete can last anywhere from eight to 15 years on average. Just <a href="https://www.angi.com/articles/how-long-concrete-resurfacing-lasts.htm">how long your resurface concrete driveway lasts</a> depends on how often you seal the concrete, the amount of traffic, how well the concrete resurfacer was applied, and even the soil quality. Poor soil that led to premature cracks in your existing concrete can quickly lead to even more cracks and problems if you don&rsquo;t fix the root cause of the cracked concrete. </p></div>

Q: Are polished concrete floors worth it?

• <div><p>Yes, polished concrete floors are worth it for homeowners who want durability, style, and low maintenance in one sleek flooring surface. You get the modern visual appeal of stone or tile with far less upkeep and far less cost. Polished concrete flooring is tough enough for high-traffic areas, it&rsquo;s a great choice for people with allergies, and it&rsquo;s easy to clean. If your existing concrete is in good shape, polishing it can give you solid value that shines on for years.</p></div>

Q: Can you put too much rebar in concrete?

• <div><p>Yes, you can put too much rebar in concrete. Too much reinforcement can cause strain in the concrete, leading to cracking. Air pockets can also form in the gaps between rebar when concrete fails to fill the space properly. The placement and installation of rebar is a specialized skill, so consult an experienced pro before proceeding.</p></div>

I recently had a Level 2 EV charger installed by Blackout Electric, and I could not be happier with the service! From start to finish, Haendley was professional, knowledgeable, and efficient.

Overall the job went well. It took two men about 4 hours from start to finish. Good cleanup afterward. Had to let the concrete set for 24 hours before driving on the floor and let the walls set 5 days before cutting off plastic filler tubes.
