How to install Oxdigi contact paper? Step 1: Roughly measure the area you will be covering and transfer the measurements to the back side of the contact paper. Grid lines are marked on the back of the contact paper to assist you in measuring accurately. Cut the contact paper to the measured size. Step 2: Peel away approximately 1 inch of the backing paper. Line up the exposed contact paper with one edge of the apply surface. Press down lightly to bond the paper and the surface together. Step 3: Smooth the paper from the center outward, working toward both the left and the right. Grip the backing paper that is peeled away and pull slightly so that the backing comes off little by little while you press the paper down. Step 4: If there is a bubble under the paper, you can use a pin to poke a tiny hole in the bubble, and smooth down from the edges of the bubble toward the hole to smooth out air bubbles under contact paper.
