There is no real substitute for a solid understanding of the principals and formations of naturally occurring rock formations, however you may find that you can 'cheat' the process a little by using CCI Artrock hardener, immagination and a texture mat. Texture mats can be easily made from taking an impression of real rock. You can re-create naturally occurring detail with remarkable ease and effect. Texture mats can be in any size or shape and can consist of a general texture pattern, or a combination of general texture as well as a pronounced crack or fissure. Staining is a simple procedure with CCI liquid pigments and CCI Activator. Cracks and Fissures are created by hand using a trowel and sea sponge dabbing gives the effect of weathering.
