8 Tips for Using Super Glue
Super glue is a very strong adhesive that is used for permanent bonding between two surfaces. It is also very fast-drying, which is why any user must exercise a lot of caution when applying it. Super glue is available in many forms and brand names, the most popular being Super Glue® and Krazy Glue®, but they are primarily based on cyanoacrylate, which is an acrylic resin known for its adhesive strength. It is also used in innumerable applications pertaining to households, factories, aircraft, automobiles, and electronics, to name just a few. Below are some tips to keep in mind when using super glue.
1. Choose the Right Product and Applicator
There are different types of super glue available, each suited to a particular surface such as wood, plastic, or ceramic. Read the application instructions on the package properly before you buy the glue so you do not end up with the wrong type. There are different kinds of applicators available as well, such as general squeeze tubes or precision tips and pens for filling in cracks or similar detailed jobs.
2. Cover the Surrounding Surfaces
Before you open the container or begin cleaning the bonding surfaces, cover all surrounding surfaces with rag cloths. This will protect anything from getting ruined by accidental spillage.
3. Sand the Surfaces Beforehand
For better adhesion, it is advisable to sand the surfaces beforehand. If the objects have any paint or varnish, you must peel it off as well. Use fine-grit sandpaper for a light sanding.
4. Clean the Surfaces Thoroughly
The surfaces of your objects must not only be sanded, but cleaned as well. If the surface is dirty, the super glue will bond to the dirt and not the object itself, so after you have finished sanding, wipe away any dust or debris with a damp cloth and let it dry. Ensure that the surface is clean of grease and rust as well.
5. Use a Small Amount of Super Glue
Super glue is a very powerful adhesive that must be applied in very small amounts. The recommended quantity is one small drop for a square inch of surface area. Applying too much will actually result in an inferior bond and will also increase the curing time.
6. Hold the Bonded Parts for About 30 Seconds
After you have applied the super glue, quickly bond the parts together and hold them for about 30 seconds. This will allow sufficient time for initial drying.
7. Let the Super Glue Cure Over a Few Hours
Before using the bonded object normally, allow a few hours for the complete curing process. This will allow maximum strength and adhesion so that you can get a bond that will last.
8. Keep Water Away from the Application Area
Any water on the glue can reduce the strength of the bond, so it is best to work in a dry, well-ventilated area.
