When Planicrete UA is mixed with Keracolor U or Ultracolor Plus grouts, available in 36 designer colors, the resulting toppings open up a world of opportunities for concrete artisans. The addition of Keracolor U produces a smooth, unsanded microtopping, while adding Ultracolor Plus creates a sanded microtopping for application on profiled or uneven substrates. The product also can be mixed with Concrete Renew concrete resurfacer to increase its bond, as well as flexural and tensile strengths in addition to increasing durability and enhancing workability on exterior surfaces such as sidewalks.
