How To Restore Stonework Using the EZ‑Spray™ System
Step 2: Applying EZ‑Spray™ Silicone
Smooth-On's EZ-Spray™ silicone is sprayed in layers over the original. The EZ-Spray™ Jr. gun is highly maneuverable allowing mold rubber to be applied to undercuts and hard to reach areas. Typically 4 layers are sprayed to an ultimate thickness of 3/8'' (1cm). Smooth-Sil™ 930 is thickened with Thi-Vex™ thickening agent. Thickened rubber is used to fill deep undercuts to prevent mechanical lock between the support shell and the original model. The process is repeated as sections are completed one at a time.
