Formwork is the element that makes it possible to build any building or structure, but it is also one of the most important building elements. Thanks to the formwork, it is possible to erect monolithic and prefabricated structures.
Why cover the formwork with oil? Using this technique, you can not only improve the properties of the formwork, but also significantly extend its life. In addition, oil gives the formwork an aesthetic appearance, and also increases moisture and waterproofing properties. Also, its use reduces the likelihood of cracks and chips that occur due to drying or overstressing of concrete. In this regard, oil is often used for waterproofing formwork. Oiled formwork will last much longer if a number of the following rules are followed:
– oil shall be applied in warm premises, since in a cold environment it can harden;
– oil shall be dissolved in water completely (at least 50%). Only in this case it will be evenly distributed over the surface;
– Do not dilute the oil with water during application. It is better to use it immediately after preparation; it is best to apply the oil in an even layer on a smooth surface, while the excess is best removed before it dries;
– when applying, the oil should be evenly distributed over the entire surface, and not just in the recesses.
When applying, it is recommended to use a wide brush or roller. All irregularities should be leveled by rubbing or soaking oil. If during operation the formwork begins to lose its properties, then the oil should be reapplied.
