ULTRAGUARD is a water-based polymeric protectant that improves the appearance and durability of concrete floors. ULTRAGUARD contains a powerful stain-resistant additive and is further enhanced with lithium silicate, which provides densification of the concrete surface. This product also contains UV absorbers that enable the ULTRAGUARD to protect colored or dyed concrete against UV degradation. ULTRAGUARD can be used alone or in combination with a reactive sealer such as EUCO DIAMOND HARD or ULTRASIL Li+ to give concrete floors a glossy finish, harder surface, and protective seal.
