"Knock-down" Texture is used around pool decks but is still tough enough to be used on driveways and garage floors.  The texture is flatter than bubble texture and creates a "lacy" look on the concrete.  The difference with knock-down is that the color is in the sealer instead of the grout itself. This factor makes it a more versatile application because the color can be easily changed without having to re-spray the texture.  Patterns and designs can also be used with the knock-down texture.
