It is possible to trim the area in which the concrete is placed by stripping away any finish and caulk. Most homeowners remove any finishing materials, caulks, paint, mortar, or varnish from the place that they intend to place the black concrete. After the scraping process, utilize a power tool pneumatic to remove all loose material and debris underneath the concrete.
After that, you’ll pour black concrete. It is the most difficult step due to the fact that the concrete does not have the time to set, which means you need to move swiftly to ensure it doesn’t crack or have voids during setting.
Allow the concrete to be set and cure before you begin the next layer. This first one can be left in outside air, or may place it in an area with air conditioning in order to speed curing. You can set the second pour after curing.
The final step is sealing. If you want an even color, then apply the sealer over the entire area. Colored cement additives may be employed to add other shades to the area.
