Colored Units are available by special order. Pictured are some examples of concrete masonry units that have been integrated with color pigments. The center block sample is our "base color," a light gray. To produce colored units, we add lime-proof, weather-resistant color admixtures consisting of metal or mineral oxides to our limestone mix design. The sample on the right features Davis Colors Mix-Ready in 677 Kailua applied to a split-face surface. The left sample uses 5447 Mesa Buff on a smooth face. Davis Colors has online swatch samples of their available colors here.

If you choose to design with color, please keep the following in mind:

• We require a minimum of four to six weeks to manufacture colored units.
• We do not have the space to hold large stocks of products, therefore, when color is requested and manufactured, the entire amount must be purchased, including any test runs. Needless to say, estimation of the number of units will be critical.
• There may be variations in color if the blocks are manufactured at different times.
  
  

COLORED AGGREGATE

Our standard blocks are manufactured using coral limestone aggregate, which produces a color ranging from buff to light gray. We also offer blocks manufactured with cinder aggregate, producing a pale pink/red color, and basalt aggregate, which results in a dark gray. Cinderlime and Basalt units are available by special order only.

SURFACE TREATMENT

Although many people are familiar with painting block surfaces, there are other options to keep in mind, such as staining. Small amounts of color mixed with sealants will provide block surfaces with a water-repellant finish and a hint of color. For more information, visit www.okoninc.com
