- Mix the Thinnest
Pour about an inch and a half of water into a bucket and add thinnest. Use a drill with a whip attachment to mix, and let it slake for about 15 minutes. - Plan the layout of your tiles.
- Drop thinnest onto the concrete with a corner trowel, and smooth it out with the flat edge of a trowel.
- Lay the mosaic tiles. Lay out the sheets of tile and press gently around the entire surface.
- Apply a sealant to the perimeter joints
After your mosaic tiles have been laid and grouted, all you need to do is to apply a sealant to the perimeter joints.
