Gallery Glass etching medium is actually a water-based paint that the artist applies directly to the glass and allows to dry. Once dry, the Gallery Glass etching medium provides the same textural opaque effect as glass etched with acid mediums or sand blasting, without the toxic chemicals, mess and heavy machinery. Use Gallery Glass etching medium with any stencil and quickly and easily etch glass, including windows, shower doors and mirrors. Apply Gallery Glass etching medium with a paint brush or sponge, or directly with the bottle tip when etching inside a leaded area for a Gallery Glass stained glass project.
Clean the glass with alcohol and a soft cloth to remove all dirt and oils from the surface, ensuring the Gallery Glass etching medium adheres properly.
Position the stencil on the glass and tape it down with masking tape so that the inner edges of the stencil cut-out are as tight to the glass as possible.
Squeeze a small amount of Gallery Glass etching medium on a paper plate.
Dip a medium-sized paint brush in the Gallery Glass etching medium and place the brush tip on the stencil next to a cut-out area. Move the brush from the stencil on to the glass exposed by the cut-out area of the stencil. Continue filling in the cut out portion of the stencil by always moving the brush from the stencil onto the glass, to ensure the etching medium is not pushed under the stencil's edge and on to the glass meant to remain masked off.
Allow the Gallery Glass etching medium to dry, then remove the stencil.
Use a thin coat of Gallery Glass etching medium to fill in the cut-out portion of the stencil; too much is difficult to control and will end up bleeding under the stencil.
