The 82ml (2.8 oz) bottle of Silicone II is the convenience size of the product and is ideal for people looking for a small application bottle to minimize strain on their wrists. It covers up to 5 square feet depending on surface roughness.

GE Silicone II Window and Door Formula adhesive can be used for glass-on-glass mosaics or for doing mosaic artwork on certain metal surfaces such as a mailbox. We do not recommend Weldbond for glass-on-glass mosaic applications because Weldbond will NOT fully cure when placed between two pieces of glass. Silicone II will cure properly and remain clear when used to laminate two pieces of glass.

Product Specifications

Read the manufacturer’s specifications and instructions here.

Silicone II is a clear sealant and adhesive suitable for wet environments. It is a single-component neutral cure silicone suitable for use on a variety of materials including glass, metal, and wood. It dries with some permanent flexibility which makes it suitable for glass-on-glass mosaics and on mosaic mailboxes. It will bind to many metals such as steel and aluminum. Conforms to ASTM C920.

Silicone II should NOT be used underwater such as in a pool or where water exposure will be continuous, such as in an aquarium. These applications should instead use thinset as an adhesive.

Product Coverage

The 82ml (2.8 oz) bottle of Silicone II covers about 5 square feet IN THEORY. Actual coverage is about 20% less than that for most users doing detailed work, but messy users or coarsely porous substrates could require significantly more glue. The coverage is greatly affected by how neatly you work and how thick you apply the adhesive.

Use In Mosaic Art

We recommend Silicone II for glass-on-glass mosaic applications, and for mosaics on top of metal surfaces, such as a mailbox. For most indoor mosaic applications on wood or cement board where no water exposure is expected we instead recommend you use Weldbond.


Dry Indoor Use

Silicone II is water-proof when fully cured, but it should not be used where permanent exposure to water is expected, such as in a pool. Mosaics in wet locations such as pools and fountains should be made with thinset bonding mortar (a type of sticky concrete) instead of adhesive.

Other Limitations

Silicone II is messier than Weldbond and is harder to work with for this reason. Always have extra rags or paper towels on hand. When using the 299ml (10.1 oz) caulking gun tubes we recommend using a caulking gun with a quick tension release lever on the handle. We carry this product because it fulfills two use cases where Weldbond is unsuitable — glass on glass mosaics and mosaics on metal surfaces.

Silicone II should not be used with small children, as it can be harmful when swallowed. We can NOT recommend it be used in a project with participants who are not yet high school age.
