LEVEL-1™ is a cement-based, interior, self-leveling underlayment designed to create a smooth, flat, or level surface before installing floor coverings. Its extended working time, low shrinkage, and superior leveling properties make it ideal for both renovation and new construction projects where next-day flooring installations are not critical. LEVEL-1™ produces a hard, durable surface that can withstand normal construction traffic for up to one year before the installation of finished flooring. Additionally, it can be featheredged to seamlessly meet existing transitions.
