Scoring acid stained concrete floors
Scoring concrete floors is a way to add more dimension and designs to acid stained concrete. The process is done by cutting lines directly into the concrete, these lines are shallow, rarely over 1/4" in depth and may be cut before or after the staining process depending on what the desired look is.
Scoring before staining will provide uniform colors on the surface as well as the lines, scoring after the stain will expose the natural color of the concrete giving it the appearance of a grouted finish.
To score the lines, the contractor may use chalk line or scoring tape, care should be taken not to use red or blue chalk line, these two colors will stain the concrete and sometimes they are extremely hard to remove. A better option is to use yellow, white or fluorescent colors as they easier to clean up or remove.
Most contractors will use a 4" grinder and a 7" skilsaw with a diamond blade to do the cutting. There are many other tools in the market designed for this purpose and also special saw attachments that help in cutting straight lines or perfect circles.
