BioLube CFR is a readily biodegradable renewable resource formulated as a concrete release agent for the concrete construction forming industry for both indoor and outdoor applications. It is designed to produce a void free concrete surface and aid in the release of the form from hardened concrete on a wide range of forming materials without creating a chemical action or causing harm to the concrete. BioLube CFRâ€™s low toxicity formula protects vegetation, wildlife, and the environment and is easy to apply with a brush, spray, or roller. Wood forms after repeated use will become water repellent and last longer. Coverage is approximately 600-1500 square feet per gallon depending on form material.
