Etch Your Own Mirror

Step 5 Apply Etching Cream

At this point, the mirror is ready for the etching cream. I used more contact paper to wrap around the remainder of the mirror, because later the mirror would be hosed off, and I didn't want to get water in the frame or around behind the glass.
With the foam brush, apply a thick layer of etching cream. I poured the cream across the lettering and then used the foam brush to smooth it across it. Use up and down, left and right motions to get the cream to fully cover the stencil. Allow the cream to sit for 5-10 minutes.
In my picture, the cream doesn't look very thick. In fact, it isn't. I actually applied a thicker layer, but I neglected to take a picture of it.
