Various patterns can be scored into the concrete to separate colors, to give a floor the appearance of cut stone, or to create designs that are unique to a clients’ imagination. When a floor is acid-stained more than one color, scored lines are necessary to delineate the color change and to prevent any bleeding of color along the line.
Double Grid Pattern
The most popular scoring patterns
are block or diamond patterns which, when combined with acid stain,
leave the impression of large pieces of polished stone.
Another popular pattern is to score a simple
8 to 12 inch border around the perimeter of rooms and then 
contrast
the color of the border from the interior space. This gives a
less structured and more tranquil appearance. Beyond these basic
patterns, the floor is the limit! Intersecting circles, stars,
flowers, vines, Celtic designs; anything you can dream is possible.
