Handling Tips
NSP™ clay scrapers and rake tools are often used to initially make the clay surface uniform. NSPTM is very solvent friendly; solvents such as naphtha, clear mineral spirits and turpentine are aggressive solvents which can be used to quickly soften and dissolve the surface. Citrus based solvents such as D-limonene can also be used but may cause inhibition when molding the clay using silicone rubber. 99% Isopropyl alcohol can be used to smooth the clay surface if a less aggressive solvent effect is desired.
NOTE: If isopropyl myristate is used on the surface of NSP™, the surface will remain soft, and it will not return to the original hardness.
