The Rose Ann Balla Project involved acid staining interior floors including a bathroom that used randomly placed black Mexican pebbles to give a nice juxtoposition in texture and color as the floors had a hardtroweled concrete coupled with an Antique Amber Acid Stain. All of the floors were coated with a clear 2-part epoxy. The living room floors employed saw cuts that would bend and meander in easy and artful ways as per Rose Ann's vision. Tom Ralston Concrete completed these beautiful Foster City floors in 2007 much to the liking of their owner Rose Ann.
