Use flexible or curved forms for curves of a 100-foot or less radius. <br /> <br />B. Form Release Agent: Provide commercial formulation form-release agent with a maximum of <br />350 g/L volatile organic compounds (VOCs) that will not bond with, stain, or adversely affect <br />concrete surfaces and will not impair subsequent treatments of concrete surfaces. <br />1. Available Products: Subject to compliance with requirements, products that may be <br />incorporated in the Work include, but are not limited to, the following: <br />a.
