Many people are not aware how critical the proper application is for a fillet bead. And the three most common mistakes they make are 1) too small a bead, 2) unbalanced beads and 3) over-tooled beads. To effectively seal a right-angle corner, a fillet bead has to be at least ⅜” and balanced evenly on each face of the angle. Make the bead to small or apply too much sealant to one side or the other and you create a weak seal. And over-tooling simply removes too much sealant from the joint and weakens its ability to perform.
Let’s look at the three most common adhesives used to bond metal to glass. They are super glue, glass adhesive, and epoxy. We’ll show you the advantages of each one and how to properly apply it.
Super glue is likely to be found in most homes, but you may not know that super glues are not suitable for all materials. There are many different formulas, and some do not adhere to glass. You should always consult the label.
If you use a super glue that will bond to glass and other non-porous surfaces, here are the basic instructions for an excellent bond.
Glass adhesives have the advantage of adhering to most or all types of glass. Blown glass, stained glass, or other varieties may present a challenge for some types of glue.
Using glass adhesive is much the same as using super glue, so you can follow the above directions. The only differences may be drying time and the use of a primer. While some glass adhesives are one-step, some systems require a primer or activator.
This is a simple process of applying activator to both surfaces, allowing a minute or so for it to dry, and then applying adhesive as above.
Epoxy is the best adhesive when gap-filling properties are required or when the dried glue will need to be sanded, drilled, or otherwise machined. It is a two-part adhesive and must be mixed before use. Once the resin and hardener components are mixed, you will have a limited working time. Consult the label because setting times can vary widely.
Once the epoxy is mixed on a disposable surface, use a plastic applicator, brush, or small putty knife to apply the epoxy to the items being bonded. Smooth it out as well as you can, then allow it to dry. Once cured, the epoxy can be sanded and painted.
Always work safely. Wear nitrile gloves and safety glasses when working with adhesives. Work in a well-ventilated area with adequate lighting. Safe workers make the best repairs.
