NON-RESILIENT TILE: STONE FLOORS

Although Marble, Travertine and Slate are technically stone, we generally categorize them separately and lump all the others, such as Granite, Limestone (Bedford stone), etc. under one category.  These stone floors have varying composition and degrees of hardness.  Nevertheless all of these stone floors are cut or quarried from the ground as such are porous to varying degrees.  Therefore they will stain and must be sealed.  Some of the stone floors may be rough surfaced and should be sealed and maintained like rough slate.

CAUTIONS

• Avoid acids.  Acids will attack Terrazzo causing etching and pitting.  In cases of extreme exposure, loss of strength.
• Avoid abrasives.  Terrazzo can be permanently scratched by harsh abrasives like sand, some scouring cleansers and overly agressive floor pads, if used in a dry state.
• Avoid crystalline cleansers, such as Trisodium Phosphate - (T.S. P.).   Crystals formed in the pores of the floor upon evaporation of the cleaning solution exert a sufficient pressure to cause a spalling or chipping of the surface.
