How to glue glass : what glue and what tools to use to glue and solder two pieces of glass or to glue various materials on a glass surface.
This guide will also be useful for repairing broken glass in a window or solar greenhouse.
If you want to glue two different materials, you will certainly have more difficulty. The ability of a glue to join two components is mainly linked to the composition of the materials to be bonded: if they have different porosities, the glue will have less grip.
If you want to join two pieces of the same nature, such as two glass components , you will have fewer difficulties as the two materials have the same porosity.
It’s a different story if you want to glue wood to glass , metal to glass, plastic or other materials.
In this article we will see which glass glue to use based on the material you intend to glue .

How to solder two pieces of glass: glass glue
Glass and mirrors are rigid materials with surfaces that are impenetrable by glue. Glass or mirror glue is based on transparent acetic silicone, or, even better, based on a special cyanoacrylate mixture.
Which glass glue to buy
There are several formulations for glass and crystal on the market, but unfortunately not all of them are truly effective. I’ll take the example of the popular super attak glass , tested to glue a glass vase to its base (gluing glass to glass): needless to say, after many attempts, the super attak glue for glass (or rather “glass” as indicated on the package) did nothing but create amorphous layers of material: I used all 3 grams of the bottle, creating an amorphous layer that I had to sand away before using another, more effective glue.
It is better to buy a generic cyanoacrylate glue than a specific but ineffective glue. Glass glues based on acetic silicone are just as effective but have much longer setting times. Even with cyanoacrylate glues, the two glass components to be glued must remain in place, but only for a few minutes, the time for the glue molecules to form a solid chain of junction.
Among the various cyanoacrylate glues on the market, I would like to point out SuperGlue produced by WoldoClean and available on this Amazon page .
This is an extremely strong, waterproof, heat resistant and quick drying liquid universal adhesive.
The adhesive is resistant up to a minimum temperature of -45°C and a maximum of +115°C.
The application is very simple: you just have to remove dirt or traces of grease from the surfaces to be glued, apply the adhesive and wait for the area to bond firmly.
Below is an image of the bottle that has received over 350 positive reviews from Amazon users who have purchased it, with an average satisfaction rating of 4.5 out of 5 stars.
Cyanoacrylate glue for glass and other materials for sale on Amazon
Cyanoacrylate glue is useful for:
- Glue the glass
- Glue a mirror
- Gluing the ceramic
- Gluing wood to glass
To glue two sheets of glass together as in the photo above, perhaps to prepare a DIY aquarium or glass tank, transparent acetic silicone is more suitable .
To wait for the setting times, you will need to make a wooden frame to hold the glass sheets (to be glued) in place for the time needed for the glue to harden (up to 8 hours for acetic silicone-based glue).

How to glue glass and wood
Wood and glass have completely different porosity. To glue glass and wood, so-called wettable glues are suitable , that is, glues that are able to penetrate the materials. Fortunately, cyanoacrylate glue is also wettable, but you will have to use more of it than you would to glue two glass surfaces.
The glue for “welding” a wooden component to glass is undoubtedly cyanoacrylate.
How to glue glass and metal
Cyanoacrylate glue , unfortunately, is not suitable for metals , although a lot depends on the metal and the size of the components to be glued.
For metal, epoxy glues in modeling paste or epoxy glues in syringes are useful (preferably two-component, two tubes to mix), these metal glues have a certain grip even on glass. To glue glass and metal, you will have to wait – keeping the components in position – from a few minutes up to an hour, depending on the quantity of epoxy glue used.
Where to buy epoxy glue ? Any hardware store can provide epoxy glues for metals but if you have to glue a metal to glass or another material (ceramic, mirrors, crystal…) it is better to buy epoxy resin mixes that offer a wider cross-linking, so as to adapt to different porosities. On this Amazon page you can find an epoxy glue useful for gluing metal and glass, but it is not suitable for gluing glass and plastic. The glue indicated can be purchased for 9.99 euros with VAT and free shipping.
Plastic requires contact glue.
The silicone and types of glues mentioned on this page are suitable for all types of glass, mirrors and crystal, even for gluing shower box glass.
