PVA Glue

Versatile Adhesive

PVA Glue

Adults and kids doing arts and crafts often get confused when they read PVA Glue as part of the materials they need in their artwork. Is it a special sort of glue that you can

get only from special stores? Do you need to climb mountains and rivers to acquire the stuff? What actually is it?

The answer is actually quite simple and not as mysterious as it may seem to be. PVA glue, which stands for polyvinyl acetate, is actually the white glue you’ve been using since you were in preschool. Yes, that glue, although another derivative of it exists, called yellow glue or carpenter’s glue. The differences between these, aside from the color, are slight. Yellow glue dries up a bit faster and has a higher resistance to moisture, but has a shorter shelf span compared to the white variant. Drying takes a bit of time depending on the amount of glue used and the materials being bonded. Putting it in a well-ventilated room will make it dry faster. Because it is water-based, it is not very resistant to moisture, and its adhesive effects will eventually wear off when constantly exposed to it. It is not advisable to store it in a cool place, because freezing breaks down its polymers and affects its sticking abilities.

PVA glue is more common than other adhesives for a reason. Aside from being less expensive, it actually offers lesser risks. It is not flammable, non-acidic, does not emit harmful fumes, and is only toxic when ingested. You don’t need special materials or equipment to work with it; you can use it with your bare hands! It is more heat-resistant than other adhesives. Furthermore, it dries clear, so you wouldn’t have any worries about eyesore caused by the glue after it cures. It is also very flexible for people working with porous materials like cloth, wood, and paper. While this type of glue is more commonly used in the classroom for handicrafts, it has many other uses, some of which are surprising.

PVA glue is used in bookbinding because of its high adhesiveness. It can also be used in leatherwork and woodwork. It works by intertwining the fibers of the wood with the chemical substances in the glue as the water in it evaporates. When mixed with a small amount of water, the glue also serves as a nice adhesive for mosaic projects and paper mache.

PVA glue also has uses that are less commonly known. When mixed with sawdust, it can be used to fill gaps. Its diluted form can be used for sealing. For example, when applied to timber, it provides a slight waterproofing quality to it. Sealing plaster with PVA also slows down its moisture absorption, allowing you to work with it longer before it dries out completely. When mixed with a cement mortar mix, it makes it adhere more to the surface that it is applied to. Another surprising function of PVA glue is that they can be used to protect cheese from fungi and humidity. You can order PVA glue online here.

Elmer’s PVA Glue

Of all kinds of glue, Elmer’s PVA Glue is probably the only one which did not only function as an adhesive, but also doubled as a play thing. Remember how you used

to play with it by leaving it on tables to dry? You must have liked how the surface softens, and then hardens like a rock. Elmer’s PVA Gluemight also have been a trusted tool while working on those art and science projects; it was responsible for those sturdy castles, dioramas, and little volcanoes that sprout a mixture of vinegar and baking soda. And who can ever forget making paper mache with only water, old newspapers, and the ever handy-dandy Elmer’s Glue?

Whatever the reason for its use, Elmer’s PVA glue always brings happy memories. There are other ways to make use of this ubiquitous glue that are just as fun and exciting. Here are some examples:

Elmer’s PVA Glue can really bring out the kid in everyone, as long as they remember playing with it. Like the way it has been so effective in making things stick, Elmer’s PVA Gluewill be always glued to people’s memories.
