Currently, there are five basic types of glue.
|Metal *||Cer- |
|Water Resistance||Gap Filling||Drying Time|
|Superglues||2-3||5||1-2||5||5||4||5||1||< 5 m|
|Wood Glues||5||-||-||-||3-5||5||1-24 h|
|Rubber adhesive |
* Metal - Soldering is best. Devcon Plastic Steel High Strength that Consumer Reports recommends. JB Weld is also recommended on some web sites, but it lacks shear strength.

You can measure its inertness by checking how quickly it polymerizes or changes into a harder substance when in contact with water. It takes an average of 30-45 seconds, so once you see any number within this interval, you’re guaranteed to have a long-lasting adhesive solution.
Super glue may be the most popular type of adhesive for aquarium plants, but aquarium safe silicone sealants are deemed the most reliable fix for both ornaments and tank cracks. Your aquarium is held together by silicone in the first place.
Not all silicon glues are for underwater applications

Best: Elmer's ProBond, Titebond III, DAP Weldwood
Plastic Welder Epoxy There is a another Devcon epoxy called Plastic Welder. It has a solvent in it as well as the epoxy resin so that it partially dissolves a plastic surface. The epoxy welds itself into the surface. This epoxy will work well with styrene or other plastics that respond to solvents. It works especially well in places where gap filling is desirable.
Use on wood and rigid materials where you want fast results; most are also intended for ceramics. Very good at filling gaps and generally water resistant.
* Best: Devcon Plastic Steel High Strength (The only one Consumer Reports recommends for metal in their 2007 report.)
Contact cement is considerably stronger. Walther's Goo is similar to rubber cement but it is much stronger
A better combination latex and silicone based adhesive is Lexel. Lexel also comes in squeeze tubes and caulking gun tubes but it costs about 3 times as much as Liquid Nails. However, it is stronger, more flexible and has better adhesive strength than Liquid Nails.
cement can be used to hold certain other plastics, and the advantage over airplane glue is that solvent for thinning and cleanup is readily available. Again, use this cement only if the joint filling cements aren't as good. It's great on pipes; onlu fair to good on PVC sheet material.

Polyurethane or Multipurpose Glue
Polyurethane glue is used for woodworking, since it fills gaps as it cures (dries). It can foam during application, joints require clamping, it can take up to 24 hours to set, but the result is a strong, waterproof bond. The excess can be sanded off and then painted or stained. The most recognizable brand on the market is Gorilla Glue, which, while reliable, can get expensive and has been known to foam excessively. Best uses: filling cracks in indoor wooden objects, making wooden toys or repairing indoor or outdoor wooden furniture--it's completely waterproof and very strong.
"All-purpose" is a funny category because each all-purpose glue has different components and different things at which it excels. Elmer's Ultimate Glue, a popular name on the market, will actually bond anything to anything, according to the manufacturer, and provides a permanent and waterproof bond. It can be sanded, painted or stained. Before it cures, it can be dissolved with acetone. After curing, it can be sanded off if necessary.
Rhino Glue is another adhesive that claims to be all-purpose. Its base is cyanoacrylate, the same adhesive in super glue, but it has been distilled and modified for use on porous and non-porous surfaces, and in extreme weather and humidity. According to the manufacturer, Rhino Glue is dishwasher, microwave and food safe. It can be kept in the refrigerator to extend the life of the glue but should be used at room temperature for best results. Best uses for all-purpose glue: broken china or porcelain, indoor or outdoor wooden or plastic furniture and other household uses.
Remember this stuff from grade school? Rubber cement is great for artwork, photos and school work, it sticks paper together quickly without wrinkling. Paper can be pulled apart and repositioned for added precision. Another bonus for the kid in all of us is that dried excess rubber cement can be peel off and it's fun to bounce, stretch and play with. Best uses: art projects involving paper and cardboard, scrap booking, and mounting framed pictures.
Alternately known as Poly Vinyl Acetate, PVA, or plain old Elmer's Glue, white glue is what you used as a kid for art projects. It adheres to porous materials and is great for filling wood joints, adhering thin wooden boards or slats, or entertaining your favorite crafty preschooler. White glue is water soluble, which has its good and bad points. You can wet and re-bond improperly placed parts, but the end result isn't waterproof. Best uses: filling cracks in wood where it won't be exposed to the elements, gluing wooden paneling in place, creating wooden game boards or making collages and school projects.
Contact cement creates a strong, instant, permanent and water-resistant bond on many surfaces. It is effective in all weather, stands up to household chemicals such as solvents and cleaning supplies, and the bonds become stronger as they age. The downside is that most contact cement is extremely flammable and toxic, and must be used in a well-ventilated, spark- and flame-free area. Store contact cement in a cool, dry place in an airtight container. Best uses: Bonding plastic laminates, wood and plastic veneers, paneling, carpet, leather, fabrics, rubber, paper, polyurethane foam and many other surfacing materials to wood, particle board, metal and similar surfaces. Contact Cement is also great for flooring, Formica counters and fixing small tears in upholstery.
