Sometimes you need to glue wood to glass for interior decorating purposes, but there is a challenge with glass showing the gobs of glue where it has dried. You can prevent this unsightly mess by using a type of glue that will both hold substances securely and dry clear so that no residue shows. Silicone glue will perform both these functions, but it exudes toxic fumes when exposed to open air. It is recommended that you wear protective gloves and a face mask that covers the mouth and nostrils when using silicone glue. Make sure the work space has proper ventilation as well.
Gluing Wood to Glass
Both the wood and glass surfaces should be cleaned before gluing. Spray the entire piece of glass with a glass cleaner on both sides and wipe it clean with a lint-free cloth. Make sure the glass is thoroughly dry before you begin. Also make sure to wipe your wooden piece with a damp cloth to remove any dust or debris from the surface.
Some tubes of silicone glue sit perfectly into a caulking gun for easy application, and others must be squeezed by hand. Then, spread a thin layer along the edge of the wood you want to attach. Quickly line up the piece with where you want to place it and set it down. Hold both surfaces securely together until they dry. The optimum drying time will be given on the back of the package of glue and it should be followed for best results.
In some cases, hot glue can be a suitable alternative for silicone, since it’s safer to use. Place a stick of glue in your glue gun and turn it on to get warm. Once the adhesive is sufficiently heated up, make a thin line on your wooden piece. Place the wood on your glass quickly while the glue is still hot and hold the pieces together for at least one minute to dry. Hot glue is not quite as strong as silicone, but for a decorative project, it may do just as well.
Removing Dried Glue from Glass
Most hot glue dries clear, but if any spills over the glass surface outside of the glued area, you can remove it using a razor blade. This is best done while the glue is not fully hardened.
For hardened glue, direct a hair dryer on low heat over the glass in order to soften the glue. Gently scrape away the glue with a razor after its been warmed enough.
For silicone glue spills, special measures will have to be taken.
