Concrete Resurfacing

Concrete resurfacing is a mode of rejuvenation where the old or worn concrete surface is cleaned, cracks and holes are filled and then it is overlaid with a new layer of concrete atop the existing layer. To begin with, the whole surface is cleaned up and the sprouting weeds and plants are removed. It is advisable to use a high-pressure clean up to remove excess dirt grease and deteriorating concrete.

Holes and cracks will be filled up with a polymer concrete or mortar that will be smoothed and leveled up evenly in relation to the rest of the surface. This will be followed up by priming the surface ensuring it is not bumpy. The surface will be covered by another thin layer of concrete and smoothed up by a trowel. At this stage, you can also add some decorations such as color or decorative stones and cover the surface for protection against external elements such as stepping on or dirt.

After this process is done, ensure your driveway or patio is out of use for like three to four days. During this time period, you should cure the surface by sprinkling water evenly on the surface to strengthen it.

The area is first evaluated for any mishaps cause probability like power lines or water passageways. Once the evaluation is done the concrete surface is demolished and excavated to the desired depth.

Replacement will involve the reinforcing the region followed by pouring of the concrete mixture over the exposed set surface to the desired depth and then structured accordingly in relation to tastes. A brush or trowel finishing process is recommended to even the surface. A four to seven-day curing regime involving sprinkling water evenly at regular intervals should be done at the same time ensuring the surface is protected from external elements such as dirt.
