Cement-based microtoppings and skim coats can be used both indoors and out to provide a clean canvas for decorative finishing with dyes or stains. They can also be custom colored by adding in the proper amount of integral color. Microtoppings are typically applied with rollers, trowels, or squeegees for various looks. They can be applied very thin or you can apply several coats. They can be broom- or trowel-finished. They usually do best with a proper sealer once cured for final protection.
