DESO Dye is a concentrated formulation of dyes and high strength penetrating vehicles intended to make ready-to-use coloring systems for regular concrete or cementitious toppings /overlays / skim coats. DESO Dyes can be mixed with acetone and/or water, depending upon application requirements. They can be used to create a range of affects from subtle earth tones to vibrant hues. DESO dyes are for interior use only. Color will fade over time in areas where the dye is exposed to frequent UV light. The quality of UV protection in windows and doors may also determine the amount of time it takes before color must be re-applied.
