installation is done using an adhesive such as construction glue or modified latex thinsets. the substrate must be installed and prepped, as per the architects specifications, to adequately support the installation. there is no grout or sealant necessary for the surface unless it will be in a busy commercial backsplash. at that point, a polyurethane coating can be supplied to be applied with a sponge brush in the field.
please note- *installation can be supported by the artist at roughly double the cost of the tiles. this pricing would include the pre-arranging of the tiles as per the artist's vision for the mix of the colors and printed tiles. then the artist would arrange them to a cement-backer board that is cut and positioned to a project template. the tiles are then perfectly and artfully set, left only to be mounted to the wall substrate with construction glue and anchor screws. the pre-arranging and mounting fees include the costs for crating.
