The application method is called Double Reverse and the glass pieces are applied to a clear sticky surface face up. When ready to adhere to the board, a very sticky tape is applied to the surface of the mosaic to lift it From the contact paper, then the contact paper is peeled from the back.
Since this is a project that will be for an exterior site I will be using Laticrete concrete adhesive to attache the glass mosaic to the hardi board. A one shot deal, so I want to test what has been done so far. Nervous - a little. Excited? Very! This application method was just featured on the mosaic group CMA on a mural installation tutorial and I know it's time for me to learn this new method. When finished, this glass mosaic sign will have thousands of pieces. I have observed that it is convenient to have all of the pieces stay put instead of shifting and this method allows for easier changes. Thanks again to Maryland Mosaics for the sample. This project is a pro bono and the Rescue and Rehab Wildlife center runs on donations. I am donating the labor and did not have the finances to order a product that I was not sure would work.
