A formwork release agent is a substance that is used to coat the formwork surface. What the substance will do is it will make the removal of the material such as concrete become easier and also to avoid the material to break or shatter. The formwork release agent will make a barrier between the material and the surface to make it be able to be removed. Without it, the material will stick to the surface and makes the removal process become much harder. Several factors such as non-uniform coating or the choice of the formwork release agent that is not suitable will affect the final product so badly.
Types of formwork release agents
There are many different types of formwork release agents that are commonly used in the construction industry. First is neat oil. Neat oil is basically a natural oil that can generate holes for air to escape and not suitable to use on high-quality concrete. Next is mould cream emulsions. Mould cream emulsions can decrease the holes for air the escape and it is good for the common purpose of the formwork release agent. The following is a chemical release agent. Chemical release agents will react with cement and creating some sort of soap at the surface. It is good for high-quality material. This type of formwork release agent should be used in a minimal amount by spray lightly on the material to avoid the process become slower. Last but not least, waxes, paints, and any other surface coatings. These substances are basically the sealers as they avoid the release agents to be absorbed with the material. They are good to use on the material with a colorful surface and increase the usage of the formwork.
The advantages of using the formwork release agents
These formwork agents have brought many advantages to the industry. The first advantages are it helps the removal process of the material from the surface much easier. It also helps to avoid the surface stay in a good shape and from damaging it. The next advantages are it can help to reduce the amount of water to be lost because of the absorption in the timber forms. The other advantages are it protects the formwork and make the formwork to be able to use again. By that, we do not have to make another formwork and it also helps to cut the cost of material to use in making the formwork. The following advantages are the formwork release agent also helps in reducing the amount of water to escape during the curing process of the concrete.
In conclusion, the formwork release agents are very useful in the construction industry as it helps to ease up the removal process of the material from the surface. Besides that, there are also several advantages that it brought instead of smooth up the removing process. To make sure the formwork release agent is working properly and it is suitable for the material that is going to be applied onto, we have to be considerate and choose properly.
