Correction fluid is a liquid used to cover up errors on paper, drying quickly and allowing writing within minutes. It was first developed in the 1950s by Liquid Paper. It comes in bottles with brushes or sponges, hoses with nozzles, or as correction tape. It has reduced waste and is commonly used in offices. It can thicken over time due to evaporation of solvents and should be kept closed.
Correcting fluid is a liquid that can be applied to paper to cover up errors such as those made by a pen or typewriter. The fluid is designed to dry very quickly when exposed to air, allowing people to write or write on it within a minute or so after application.
The first versions of corrective liquid were developed in the 1950s by the founders of Liquid Paper, a famous brand of this product. Another famous brand is Wite-Out®, many Europeans know Tipp-Ex. In all cases, it is typically white, reflecting a very common color choice for paper. In addition to correction fluid, people can also purchase correction tape, which works in much the same way.
Prior to the development of correction fluid, when a mistake has been made, an entire document may need to be discarded if the mistake cannot be covered or erased. Corrective fluid has drastically reduced waste and headaches for weary secretaries, and has become a ubiquitous feature in offices as a result. By convention, this fluid is not used in formal correspondence, because some people find it to look a bit tacky. If an error is made in an official document, the document will usually be reprinted without the error.
Classically, liquid concealer comes in a small bottle with a brush or sponge fitted to the cap for ease of use. It can also be found in hoses with nozzles that typically use roller balls to control fluid flow, or in the form of corrector pens. Some people prefer to use correction tape because it is neater than a liquid option and can be written on right away, and several companies make correction tape in dispensers that are very easy to use for this very reason.
Users often find that this product thickens over time, sometimes becoming bulky and impossible to use. This is because the solvents that keep liquid concealer in a liquid state slowly evaporate over time, especially if you leave a container open, exposing the fluid to air. One way to keep the solvent from evaporating is to buy it in small containers and keep the containers closed when not in use. Incidentally, these same solvents can cause health problems, so it’s a good idea to avoid inhaling the fixative fluid fumes.
