Grossezza XT is a high viscosity, single part, plaster type crackle that should beapplied 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 layerof Crackle Size may be needed to guarantee adhesion)*When used in conjunction with Perfetto or ArtsSyVille 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 overour Roccia PL to produce small cracks.*It is not necessary to seal XT prior to color washing. An attractive finish can beachieved by simply troweling the XT on the wall, tapping it with the flat surface ofthe 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 XTwith the Faux Colorants. *The primary factors affecting the size of the cracks isthe film thickness (heavier applied material will crack larger), drying time, andamount or thickness of the crackle size applied. Available in quarts and gallons.
