Problems Associated with Decorative Concrete

Decorative concrete can at times appear plain. However, by adding acid stain or concrete stain treatments to the decorative concrete, you can add a heightened creativity much like an additional lens placed over a camera. With that heightened creativity, you can still find certain problems with appearance nonetheless which are difficult to diagnose as they remain under the surface. There can be damage during a decorative process suggestive of underlying causes. Some consultants who are familiar with plain concrete problems can still remain puzzled by confusing decorative concrete problems. Overall, being aware of the potential problems can help you to address them before they air angry bird arise.Common problems associated with plain concrete, acid stain, or stained concrete include air entrainment. This is a problem, which can arise when there is not adequate entrainment in order to prevent freeze-thaw damage. Generally, air entrainment can prevent your concrete from scaling and from spalling. In climates in southern regions, air entrainment controls excessive bleed water from falling off of the concrete surface and creating finishing problems. If you have too much air, you can create scaling during the machine troweling. Another common issue is high water-cement ratios. This takes place when you have design strength that is lower than specified, lower than specified carbonation, porous or weak surfaces, increased shrinkage, or excessive efflorescence.Low strength in the cement can result from a poor mix design or from a lack or curing, or excessive water in the mix. This problem Air Swimmers can increase the possibility of the cement cracking on the acid stain, or stained concrete. It can also cause excess surface wear, Air Swimmers or porous concrete for the acid stain, or stained concrete. If the concrete is less than 4000-psi strength in climates that are freeze-thaw, then scaling can result. If bleed water is present, then the strength of the surface is reduced. With high moisture levels in the concrete, you can see many problems arise. However, applying waterproof coatings can combat this before the levels are low enough to avoid blemishes, spalling, and blistering. During cold weather, placing concrete and the initial set takes longer which can create extended bleeding times. By using unvented construction heaters, you can reduce the rate of carbonation for fresh concrete. During hotter weather, there is less time between placement and the initial setting of the concrete rc flying fish and this can create moisture loss from the surfaces.It is important to understand how acid stain or stained concrete reacts to plain concrete problems. For instance, when a dry-shake color used on decorative concrete, the scales generally have color on a single side and plain concrete, which is then bonded to the colored side on the back of the scale. This happens because the hardeners for shake dry color provide a dense layer, which protects the colored layer from any potential freeze-thaw damage.
