Grossezza XT is a high viscosity, single part, plaster type crackle that should be applied over a well primed surface of Canvas White. (if using another basecoat, testing of adhesion should be done prior to proceeding with a job, as a thin layer of Crackle Size may be needed to guarantee adhesion) When used in conjunction with Perfetto Crackle Size, it produces a wide range of blocky crackle style finishes. Additionally, XT may be applied without the use of Crackle Size, if applying over our Roccia PL to produce small cracks. It is not necessary to seal XT prior to color washing. An attractive finish can be achieved by simply troweling the XT on the wall, tapping it with the flat surface of the trowel to obtain highs and lows, allowing the XT to dry off about 30% to 40% and then knocking the highs back down and color washing once dry.
Color development is achieved either by tinting and/or color washing the XT with the Faux Colorants. The primary factors affecting the size of the cracks is the film thickness (heavier applied material will crack larger), drying time, and amount or thickness of the crackle size applied.
One gallon covers 50-70 sq ft depending on application.
