SpeedFinish Patching and Finishing Compound is a fast-curing, cement-based patching and skim coating compound that provides a smooth finish to a variety of substrates prior to the installation of floor coverings. Formulated with Controlled Cure technology, SpeedFinish eliminates installation problems of bond failure, crumbling and staining of resilient flooring due to free-moisture found in traditional underlayments. It allows installation of most floor coverings in as little as 15 minutes.
