How do I Apply Stucco on Dense Glass Material?

Apply stucco over any glass surface using a chemical bonding agent.

Stucco is a mixture of water, sand and Portland cement mixed to the texture and consistency of plaster. Stucco is usually applied over wood, or a porous, rough surface, using wire mesh and a cement base coat. However, with modern advancements in chemistry is it possible to apply stucco directly over even the smoothest surfaces, including any glass surface, without a base coat or additional material for the stucco to grab on to, such as wire mesh. A chemical bonding agent applied directly to the glass surface beneath the stucco creates a bond at the molecular level between the glass and stucco, allowing the stucco to adhere regardless of the slickness of the glass.

Things You'll Need

• Glass cleaner
• Cleaning cloth
• Protective eye wear
• Protective gloves
• Poly vinyl acetate bonding agent
• Paint tray
• Paint roller, medium nap
• Stucco
• Trowel

Instructions

1. Clean the glass surface of all dirt and oily substances with glass cleaner and a soft, clean cloth.

2. Put on protective eye wear and gloves before working with the bonding agent.

3. Pour a poly vinyl acetate bonding agent into a paint try and use a medium nap paint roller to cover the glass surface with an even layer of the bonding agent. Allow the bonding agent to dry to a tacky consistency before continuing.

4. Trowel the stucco directly over the bonding agent and allow to dry according to manufacturer's instructions.

Tips & Warnings

• Do not use a chemical bonding agent or a stucco treatment on exterior exposed areas prone to frequent soaking. Use only in dry areas or in areas that dry quickly and completely.
