Video clip test demonstration featuring granite by Innovative Stone Stonemark granite with Permashield sold at Home Depot and half sealed with Granite Shield. The tape is uncut and unedited. The Stonemark granite started absorbing water and darkening within 2 minutes of water being poured on the granite. If water can do this within minutes you can imagine what Kool-Aid, coffee, red wine or oil could do. Also featured on this video black CaesarStone half sealed with Granite Shield.
Granite Shield has no plastic or silicone and it is a breathable, penetrating sealer and will not scratch or yellow.
