Granite and slate are both natural stones, providing popular and ideal building
materials in modern constructions, particularly for tile flooring. However,
granite and slate possesses quite different physical and chemical
characteristics so requiring different means of care and maintenances.
Here is a comparative maintenance guide for granite and slate tiles.
Composition: Quartz tile, Feldspar - varies
Hardness : Extremely Hard, second hardest only next to diamond
Absorption : Yes, Degree Varies - Oil, Water
Limitations : Absorbs oils and other acidic liquids, brittle, easy to be chipped
Sealer : Sub-surface repellents in general, oil repellent type recommended
Cleaner: Neutral pH detergent or pure soap
Finish Sustainability: Polished and honed are most popular; Ok to apply wax
Other Maintenance issues: Granite Tile is very typical in kitchen counter and
flooring applications. Sealing is strongly recommended for most granite stones. Granite Tile is the hardest polished stones commercially available and
can be used in highly stressed situations. Even polished granite tile can be more absorbent to liquids than many people
would think. Flamed granite tile surfaces are very absorbent due to the stress fractures in the stone
formed during the flaming process and should be sealed if it is desired to maintain the original color and appearance of the stone over time.
