Super glue and other adhesives for small home repairs

Repair instead of throwing away – super glue and other adhesives for DIYers

Glues are used almost everywhere from heavy industrial processes to everyday consumer goods. Adhesive like super glue is also a great thing to have at home, in the car or somewhere else within hand’s reach. There are several types of adhesives that are perfect for home repairs and DIY projects. They can save you money as you can repair broken items without needing to buy new ones.

Super glue is by far the most well-known adhesive used in repairs, yet it is not the only option. There are numerous adhesives that can be used for a wide variety of applications. Here we will take a look at the most common glues used in households.

Super glue – the best adhesive for small repairs

Substrates: Metal, rubber, wood, ceramic, plastic and porcelain

Super glue is an adhesive that ended up on the list of most useful inventions in the 20th century. And that is no wonder, as the cyanoacrylate based glue bonds almost anything as long as the surfaces are small and flat.

Curing process of cyanoacrylate glue

Generally, there are two types of super glue: gel and glue. Both of these have superior bonding power. The difference is that gel is less likely to drip and leak. Super glue is often called instant glue as it cures in a matter of seconds. You should, however, not be fooled by the very short curing as the full cure may take up to 24 hours. Therefore, after gluing the parts together, you should let the adhesive cure longer and keep the parts together with clamps or zip ties.

Where to use super glue

Most super glues are suitable for a wide range of substrates and they are ideal for glueing broken dishes, shoes, tears in car upholstery, disconnected car mirrors, handles, hoses and many more applications. Just make sure the manufacturer confirms the use of their product on the specific material.

The best products

As instant glue is a preferred product for many applications, multiple brands offer these products. Although everyone has their own preferences, two brands can be said to be more popular than the rest: Gorilla and Loctite.

Where NOT to use super glue

Even though super glue is very strong, it is not the best choice for filling gaps and cracks. This is due to the fact that super glue forms thin, transparent layers which is not hard enough to remain in form. For gap and crack filling, you could use epoxy instead.

Strong bonds on large surfaces with epoxy glue

Substrates: Metal, plastic, wood, fiberglass and composite materials

Epoxy is one of the strongest adhesives for industrial and consumer use. It is usually a two component system which is sold a set of resin and hardener packed separately. Prior to application, the two components must be mixed with each other on a surface like newspaper or cardboard. When the components are mixed, the chemical reaction that results in curing strats. therefore, the epoxy glue must be applied soon after mixing.

Epoxy curing time

Epoxy cures when two components are mixed with each other and a crosslinking process is started. Some epoxy products cure faster than others however, the rule of thumb is the longer the curing time the stronger the bond. Like super glue, epoxy should be let cure for 24 hours to reach its full strength. Use clamps or zip ties to create pressure and keep the parts in place until the adhesive is fully cured.

Where to use epoxy glues

Epoxy glues work the best where super glues don´t: large surfaces and crack and gap filling are common applications. Epoxy cures into a plastic like, transparent or opaque bond which is hard to beat it toughness. Therefore, epoxy beats super glue in strength also when bonding metal or wood. Common epoxy applications include shoe repairs, fixing handles (for example screwdrivers) and minor car repairs including disconnected mirrors and patch cracked lights.

Wood adhesive for crafts and repairs

Substrates: wood

Wood is a porous material and requires a special adhesive which soaks into the pores. The wood glues are used for wood to wood bonding and it is common for crafts and home repairs. Wood glue is usually white and becomes transparent as it hardens. The glue should be applied by spreading an even amount on both surfaces that are about to be banded. After that the parts are connected and should be clamped together to ensure they stay in place till the glues is fully cured.

Curing wood glue

Like for super glue and epoxy, the longer the product is let cure, the stronger the bond. Many products are available and they all have specific curing times. Stick with the manufacturer’s advice to achieve the best result.

Silicone glue for watertight bonds

Substrates: Glass, plastic, metal and wood

Better known as sealant, silicone creates watertight bonds which resist chemicals and weather. Therefore, the best use of silicone glue is sealing there where adhesive properties are needed, too. Silicone glues cure to form a transparent or colored bond which remains flexible under any circumstances.

Uses of silicone glue

As mentioned, silicone glue is often used in applications that require both: sealing and bonding. Common uses of silicone glue in home repair projects include bathrooms and glass to glass connections such as in building and repairing aquariums. Silicone is also suitable for outdoor applications thanks to its superior water and weather resistance. Other uses are door frames, vinyl tops, roofs, shoes, toys and many more.
