Stone tiles have been used since the beginning of civilization, in practical ways, such as paving patios, walkways, and floors, and in artistic ways, such as creating beautiful mosaic patterns that attract the eye provide a sense of wonder to the viewer. Skilled craftsmen were required to create the ancient beauty. Modern installations follow the age old traditions, but new installation techniques and tools have made it possible for almost anyone to create a beautiful stone tile installation.

How do I set the stone tiles?
Then use the notched edge to create ridges in the adhesive/mortar, following the recommended trowel size found on the packaging. Follow by flattening the peaks of the thinset slightly with the smooth side. This will reduce the chance of having gaps or voids behind the tile. e.

Do not apply an overly thick bed of adhesive/mortar under the stone - this will make the finished surface uneven and increase the possibility that the adhesive/mortar will shrink as it dries.
Clean any excess adhesive/mortar from the joints with a damp sponge or cloth as you install the stone tile. Use spacers to achieve a consistent grout joint. Disposable plastic spacers can be purchased wherever stone supplies are sold. When installing mosaics, keep the joint between the mosaic sheets consistent with the joint size on the sheet for a truly professional looking installation.
When the adhesive/mortar has fully set and dried, seal the stone with a penetrating stone sealer. Then mix and apply the grout of your choice in the joints. Sponge excess grout off the surface as you go. When the grout has dried, apply another coat of sealer to the entire installation.
After cleaning up, invite some friends over for a party, and watch them admire your excellent work.
