Sealing aggregate and stamped concrete is a task everybody should consider doing after the concrete has been finished. Sealing is a highly recommended step to prevent damaging your investment.
There are several benefits to sealing stamped and aggregate concrete, from adding to the finish to maintaining it during harsh weather. Sealing concrete surfaces, due to the porous nature of concrete, also helps keep water and salt out.
When salt gets into the pores, it leaves an unsightly white mark on the concrete. Water in the concrete’s pores should be avoided in cold climates due to freezing. As water expands in freezing temperatures, this can lead to cracks in the concrete and cost you more money in repairs.
Besides sealing your concrete with a standard water or solvent sealer, another option to consider is using a colored sealer. Using colored sealer will cost a little more; however, depending on the look you are aiming for, it might be worth the aesthetic value.
It’s important to wait at least 21 days – preferably 28 days – before sealing your concrete; this is the standard cure time. Sealing every year will also make sure you continue to have a great surface.
In temperatures below 60 degrees Fahrenheit, the sealant’s chemical makeup can change and cause it to not seal properly. When handling and storing sealant, be sure to avoid freezing temperatures and place it in a dry area.
