Weldbond Universal Adhesive
Weldbond Adhesive is a professional glue that meets all your fine arts and crafts needs. It dries completely within an hour of application and is transparent and flexible with no cracking when fully bonded. Use Weldbond with paint, wood, mosaic tile and glass, clay, model building and sculpture, canvas cloths, all papers, suede, and leather. It bonds to most anything with the exception of some types of rubber, plastic, and cast metals. Weldbond is non-toxic, odorless, and cleans up with water.
Great for mosaics on glass, as it is easy to apply and dries clear. Recommended to use with smaller tiles and glass mosaic bits as it will remain cloudy until completely dry. As the glue will dry around the edges first, the centers of larger pieces may never fully dry. If adhering large pieces, try a clear silicone.
