The layer of good quality concrete correctly applied to ready-made concrete will last from 10 to 25 years. Even so, it must be resealed every 5 to 7 years, depending on the environmental conditions experienced by the overlay, the type of materials used, and the type of finish used on the overlay. The children will be boys, right? Well, not so much for this furious homeowner from Irving, TX. It seems that some of the neighborhood children sneaked into their backyard right after a contractor had poured the pool deck and decided to “customize” it in several places with their initials.
The last thing on our owner's mind was to tear off the platform, and we agreed; all we had to do was apply our skim concrete layer and bury the problem under a new, thin layer of concrete. As the concrete cures, it expels a lot of water that was part of the mixture, if we put a layer on top of that, it's like trying to put the cap back on a shaken soda bottle. That liquid just wants to come out and it will push that layer and try to remove it. After 28 days, assuming that it is not in freezing conditions, enough water has been expelled so as not to weaken the bond between our skim concrete layer and the original slab.
I just had a reputable contractor pour a concrete yard and apparently he didn't have enough help at the time and he prepared for fast and it turned out terrible. He promises to do the right thing at all costs, even if it means taking a jackhammer and starting over. My question is, he wants to try to grind it and cover it first (including the porch and stairs). Will he support a skimmed coat as well as concrete poured correctly? Or should I tell him to pull out his jackhammer? It's my choice, A.
The answer to your first question Will a skim layer hold as well as properly poured concrete? Yes, if done right, if your contractor does not have experience applying overlays, would ask you to do so or hire an experienced installer of elite chalk systems, Elite crete coating products are stronger than concrete and, if applied correctly, will last for many years. If a layer is not installed correctly, it will delaminate and peel off shortly after it is installed. Take a look at this decorative concrete screed that we installed on a concrete floor. By using concrete as a material for the entrance to your house, you expect it to be sturdy and durable.
The main reason is that, in addition to being affordable, it is known for its durability and versatility. Not only can you customize the concrete to achieve the look you want, but you can also count on that look to last for years. Or, if there is too much damage and crumbling, you may need to weigh the pros and cons of concrete resurfacing versus. They will be able to evaluate existing concrete and determine if it is a good candidate for resurfacing.
A coating compound has a special adhesive agent inside it that allows it to adhere to old concrete. You can apply thinner layers of concrete coating to restore the wear surface of an existing coating, but this will not add structural strength to any of the concrete layers. Temperature differences mean that the concrete layer will expand and contract at a different rate than the base concrete. If you want to re-pave your concrete driveway, many consider it the “midpoint of caring for your driveway”.
You can repair this type of concrete coating in some cases, but it usually needs to be replaced if it is damaged. Applying a concrete screed is time consuming and can be expensive, so it is vital to know the typical lifespan of a concrete screed and the factors affecting its life span. It is almost impossible to guarantee that the concrete screed does not crack, break or be damaged in any way, since it is almost impossible to ensure perfect adhesion to the concrete base. The concrete layer repairs the surface layer of the concrete by placing a layer of new material over the existing base slab.
Working with concrete can be stressful because you have to do everything at the right time before the concrete hardens. According to the Portland Concrete Association, the best concrete coating thickness is 1-2 (25-50 mm) inches thick. You can usually make a coated slab look the same as the original concrete if that's the look you want. .
