Murals, accents and listellos are pre-sealed by StoneImpressions. If you wish to seal the grout in between the tiles, we recommend that you use a water based penetrating sealer. Test first on a small sample of tile. Follow maintenance schedule recommended by sealer manufacturer. StoneImpressions does not warranty, and will not be responsible for any claims regarding sealers.
Grouting is a matter of personal preference. Grouting the entire image (especially with unfilled travertine) will fill the natural holes in the stone, causing the image to become randomly spotted with grout. A grout bag may be used to grout only the joint lines of the mural, thereby avoiding the spots of grout. A third option is to not grout between the lines at all – simply position them right next to each other. Talk with your installer to decide which method will work best for your installation space.
Stone is a natural product, and care should be taken to protect it from harsh abrasive cleaners and abrasive cleaning tools. Cleaning can be done with a soft cloth, warm water, and non-acidic soap. Avoid any care products that contain abrasives, phosphoric acids, scouring powders, chlorine, acetone or glycolic acids, and avoid brushes and scouring pads.
