Mistakes may occur when contractors add too much water, applying sealer incorrectly, and adding too much water on the concrete.

Answer 1

Water is ordinarily included to concrete in one or both of the taking after circumstances: First, water is included to the concrete in a conveyance truck to extend droop and diminish pouring or arrangement exertion. This will lead to concrete with brought down quality and decreased toughness. As the water/cement proportion of the concrete increments, the quality and toughness will decrease. In the moment case, water is commonly included amid wrapping up of auxiliary part. This leads to scaling, crazing, and tidying of the concrete.Improper arrangement of the formwork will lead to discontinuities on the surface of the concrete. Whereas these discontinuities are unattractive in all circumstances, their event may be more basic in ranges that are subjected to tall speed stream of water, where cavitation-erosion may be actuated, or in bolt chambers where the “rubbing” surfaces must be straight

Answer 2

Here are some common mistakes that may occur during the finishing of concrete:

Poor surface preparation: Failing to clean or properly prepare the concrete surface before finishing can result in a rough and irregular finish.

Starting too early or too late: If the concrete is finished too early, it may be too soft and result in surface imperfections. If it's finished too late, the surface may be too hard and difficult to manipulate.

Improper troweling technique: Over-troweling or troweling at the wrong angle can lead to a surface that's too smooth, causing it to be slippery when wet.

Inconsistent application of surface retarders: Inconsistent application of surface retarders can result in a finish that's blotchy or has an inconsistent texture.

Not using proper tools: Using the wrong tools or tools that are in poor condition can result in a poor finish and increase the risk of surface defects.

Improper curing: Improper curing of the concrete can result in cracking, scaling, or discoloration of the surface.

Weather conditions: Hot and windy weather can cause the concrete to dry too quickly and affect the finish. Conversely, cold and damp weather can cause the surface to set too slowly and increase the risk of surface defects.

Answer 3

There are several mistakes that may occur during the finishing of concrete. These include not using the proper tools or techniques, not allowing the concrete to cure properly, not using the right amount of water, not using the right amount of concrete, and not using the right type of aggregate. Additionally, it is important to ensure that the surface is level and even, and that the edges are properly finished. It is important to consult with a qualified contractor to ensure that the concrete is finished correctly.

Answer 4

Contractors are either adding too much water to concrete, improperly antiquing it, or incorrectly applying sealer. These three errors cause at least 90% of the problems I see, including sealer flaking, whitening, bubbling, and shortened sealer life span.

Answer 5

Underestimating the Amount of Concrete You Need.

Ordering the Wrong Kind of Concrete.

Improper Installation of Concrete Forms. 

Using the Wrong Cement-to-Water Ratio.

Waiting Too Long to Level After Pouring.

Removing the Forms Too Soon. 

Forgetting About Textured Finishes.
