UltraTile's Pro-Level Ultimate is a high-performance, semi-rapid curing smoothing levelling compound specifically designed for use with underfloor heating systems. Its advanced formula allows for application on virtually any subfloor, making it suitable for various substrates. With a quick curing time, floor coverings can be installed on top in as little as 4 hours.

Pro-Level Ultimate incorporates Ecosphere technology, which includes 20% recycled material, contributing to improved application and reduced environmental impact. This product offers excellent adhesion to almost all substrates, including old adhesive residues, eliminating the need for priming in most cases.
