South Carolina State Museum
With more than 70,000 artifacts, the South Carolina State Museum calls the building in which it is housed its largest artifact. Built in 1894, the former Columbia Mill houses exhibits devoted to art, history, science, and technology. Listed on the National Register of Historic Places, the building was the first completely electric textile mill in the world and the first major industrial installation for General Electric.
Existing Substrate
While in surprisingly sound condition given its 100+ year age, the concrete was uneven and had a number of cracks throughout. Some areas of the concrete subfloor were damaged. Former dividing walls within the structure presented deeper subfloor imperfections with brick remnants left behind. As with many older subfloors, evidence throughout the space indicated past leveling efforts with varying degrees of success.
Preparation
The floors are thoroughly swept with all debris removed. Loose subfloor materials are removed and trenches and open spaces vacuumed. Schönox SEZ Plus, rapid setting screed, is an ideal choice to fill voids and trenches.
Priming Using Schönox VD
Schönox AP Application
Rennovated Subfloor
Before the subfloor project, the substrate was not suitable for any floor covering. The Schönox AP will be ready for flooring installation in roughly 24 to 48 hours.
