SpexCrete 450 Light Weight Base Coat is Certified to Work With SwiftSet Self-Leveler


The Stone Edge Surfaces 2-layer Multi-Story Flooring System is comprised of a Base Coat layer of a foamcrete material like the SpexCrete 450, and a Base Coat Topper of Stone Edge Surfaces 7,000 PSI SwiftSet Self-Leveler.

Both SpexCrete 450 and Stone Edge Surfaces SwiftSet Self-Leveler have been tested for adhesion and strength, and both have been “independently” pump tested and certified by ChemGrout  against all major competitors as a 9 out of 10 (SwiftSet) and 10 out of 10 (SpexCrete) for ease of use, pumpability and pumping distance of 300 feet.

Both SpexCrete and SwiftSet Self-Leveler have been independently ASTM E84 Fire and Smoke tested and certified with a Class A ratings.

SpexCrete 450 is a single component, just-add-water, Ultra Lightweight Polymer Modified Underlayment designed for deep fill flooring applications, and it reduces the dead load weight by ~65% as compared to traditional concrete underlayment systems. SpexCrete and SpexCrete 450 are a different manufacturer than Stone Edge Surfaces and can be reached at: Spexcrete.com and 440-462-1500 for more information about their products.

Stone Edge Surfaces SwiftSet Self-Leveler is a fast setting (2-4 hours), walkable in (4- 6 hours), “pre-sanded”, single component, just add water, polymer enhanced, non-gypsum, Portland cement and proprietary additive self-leveling underlayment top coat mix used to create a smooth flat and level surfaces for the installation of various flooring types.

When used together, SwiftSet Self-Leveler and SpexCrete 450 create a very versatile lightweight concrete underlayment system that is as much as 65% less weight per SQFT than standard self-leveling underlayment systems.
