Why maintain concrete?
Problem #1 – DiscolorationThis issue is probably the simplest and the least painful, when it comes to a solution. Usually, discoloration can be caused by many various factors, such as: weather conditions, excessive troweling, curing time etc. If you begin to notice dark or light splotches on the concrete, it’s better to raise alarms right away! One of the proper ways to deal with discoloration would be using a concrete cleaner, which is designed to give concrete a better look. But, if the concrete cleaner did not show any results, try a concrete stain. Apart from restoring the color, it will also protect the surface. If you want to completely eliminate the possibility of concrete discoloration, make sure to strictly follow placing, finishing and curing instructions.
Problem #2 – ScalingScaling usually starts with a small area, but, if left untreated, it spreads further, and the concrete begins to flake or peel away layer by layer. It occurs as a result of poorly done concrete finishing or due to water seepage, exposure to freezing and thawing cycles, lack of curing time, etc. It’s always better to prevent scaling, either by using a proper concrete mix, designed for exterior flatwork or being very cautious during finishing the concrete. For instance, if standing water has not been evaporated fully, never proceed with the finishing. Furthermore, remember to avoid using de-icing salt and chemicals in the first winter after the concrete was placed. However, if the surface began to scale despite everything, you need to start fixing damaged areas ASAP. You will have to apply a new layer of resurfacing concrete, which requires roughing up the whole covered area to prepare it for the repairing. After applying the new layer, let it cure for the night, and then apply a waterproof finish to protect it from scaling again.
Problem #3 – CrackingCracking is the most common problem of the concrete pavement. At first, cracks appear on the surface, but then they slowly make their way to the bottom of the slab. If you allow cracks to proceed further and reach the subgrade, concrete structure will have to be fully replaced. That is why we recommend fixing small cracks before it gets serious. The damaged areas must be cleaned from a loose material and filled with a concrete filler. Applying an additional sealant product afterwards would be a plus, as the sealant will strengthen the repaired area and protect it from water.
Problem #4 – CrazingThe last, but not the least, most common concrete “disease” in our list, crazing appears as a network of tiny cracks in the concrete surface. It happens due to inaccurate mixing or disregarding of curing procedures. Even if these small cracks do not extend deeper into the surface to impact its durability, they may ruin the general look. If you notice crazing in your concrete, the easiest solution would be to contact a contractor who placed it. While experienced companies care about preventing crazing with their quality installation process, they cannot give the absolute guarantee it won’t happen. Nonetheless, it is possible to cover such type of damage, if there is no way to absolutely eliminate it.
The Best Way to Fix The DamageYou can avoid discoloration, scaling, clacking, crazing or any other common concrete problems by following these 3 simple rules:
- Use the concrete mix of the highest quality. Yes, it is costly, but it’s also lasting.
- Follow proper finishing procedure. Do not rush the process. Everything should be done according to the instructions, if you want your concrete pavement to last.
- Develop a maintenance plan and check the state of your concrete.
