Grossezza XT Crackle is a water based plaster type of crackle. It is typically used by applying a thin coat of "Crackle Size" to the base coat and after about an hour, when the Crackle Size is dry, the Grossezza XT crackle is applied. The thinker you apply the Crackle Size and the thicker you apply the XT, the larger the cracks. This crackle can also be used over the Roccia PL plaster without the need to use Crackle Size. You simply roll or trowel on the Roccia PL and then once its dry, trowel a thin to medium coat of the XT Crackle over the top and you have a beautiful layered crackle. This is typically done in a patchy manner to allow some of the PL plaster to show through. The video on Old World Bricks done by Perfetto Chemist Ted Heath is a very good instructional video.

Don't forget your Crackle Size

Technical Specs:
Grossezza XT is a high viscosity 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.
