Follow The below Steps to install your mosaic to your floor:

1. Clean the surface on which the mosaic will be installed

2. Gently clean the mosaic with a cloth to ensure it is free of dust and dirt

3. Apply a stone sealer to the mosaic to protect the stone during the installation. This coating should be left to dry for at least 3 hours to ensure that the sealer is fully absorbed by the marble.

4. Take the plastic protectionoff thje back of the mosaic leaving only the mesh.

5. Gently buff-out the backing of the mosaic to remove some of the excess glue and ensure that the mesh is exposed as much as possible. This buffing may be made with a metal brush. Don't over buff the surface or you will run the risk of breaking the mesh.

6. Clean the Debris with a vacuum cleaner or a broom and inspect.

7. Prepare and apply the thinset on the surface over which you wish to install your mosaic. Apply at least 1/8 of thinset and mark 2mm deep canals across the surface or as recommended by the thinset manufacturer.

8. Set the mosaic in place over the thinset, lightly applying uniform pressure over it, ensuring that the thinset penetrates through the mesh and between some of the tesserae of your mosaic.

9. Continually clean the mosaic surface with a wet sponge ensuring that the thinset does not excessively accumulate in any area over the mosaic.

10. Allow the recommended thinset manufacturer time to dry. Usually 24 hours.

11. Prepare a non-sanded grouting mix. Please use the minimum grouting thickness mix available, usually it’s made for grouting less than 1/8”.

12. Grout the surface of the marble mosaic like you would grout any other tile. The color of the grouting mix should be such that it doesn’t dramatically contrast with the darker colors of your mosaic, or with the lightest colors. An average color grouting mix should be utilized. If you are looking for an antique look you could pursue a dark grey grout.
