Things You Will Need
Diamond Cutting
-
Determine the design you will follow to cut lines and patterns into your cement. These can be found in commercially produced stencils, templates or masks or through patterns of your own design.
-
Trace your design onto the cement using chalk. For straight lines, snapping a chalk line is best.
-
Insert a concrete cutting blade into your cement cutting tool. The blades may be from 1/8-inch to 1/4-inch thick depending upon your design. If you will be grouting your cut lines, a minimum cut depth of 1/8-inch is required to provide proper grout adhesion.
-
Remove cement dust using your shop vac.
Abrasive Blasting
-
Determine the area of concrete that will be etched away by your abrasive material. This method of surface engraving is appropriate for borders, logos, letters or numbers.
-
Mask the area that will not be etched using abrasive resistant masks or stencils.
-
Load the abrasive material into your blasting tool. Abrasion on cement can be performed using sand, dry ice or calcium carbonate.
-
Remove the top layer of cement using an evenly applied coating of abrasive in a gentle back and forth motion of the spray attachment.
-
Remove loose material with your shop vac.
Acid Gel Etching
-
Determine that your cement surface has not been sealed. Apply a test drop of muriatic acid in a corner to see if the concrete is effectively etched. Sealed surfaces may require the blasting technique outlined in Section 2.
-
Apply your mask or stencil to the area you wish to work.
-
Apply the acid-based etching solution to the area you wish to etch using your paint brush.
-
Allow the treated area to sit according to package directions.
-
Wash remaining acid gel away with an application of warm water. Allow the cement to dry.
Concrete Engraving
-
Apply your standard or custom-created template to the concrete surface.
-
Trace the design area using your chalk or snap your chalk line to lay out straight lines.
-
Place your diamond blade into your angle grinder. Grind the cement surface according to the specifications of your design.
-
Remove loose material with your shop vac.
