In recent years, with people's understanding of epoxy floor paint, its application scope is becoming wider and wider. During the construction of epoxy floor paint, there is often a situation of oil contamination on the base floor. At this time, it is necessary to deal with the oil contamination, otherwise it will lead to the problem of peeling off of the floor paint coating. The following epoxy floor paint manufacturers to share with you the common methods of oil removal.
1. Burning with flame, but this method only aims at fuel oil. When removing oil stain, we should pay attention to not over-burning, otherwise, the concrete base will burst.
2. Wash with organic solvent or water-borne detergent. After cleaning, the dirt should be removed in time. Otherwise, the water or solvent volatile oil contamination will remain on the base surface. The base surface cleaned with water-borne solvent must wait until the base surface is completely dry before the floor paint can be applied.
3. For large areas of heavy oil-polluted ground. For example, the concrete floor of automobile repair plant is mostly eroded by oil contamination for many years and has penetrated into the concrete structure. The general method is difficult to remove completely. We usually use sandblasting method to grind and remove the surface of oil penetration base surface until the clean and unpolluted base surface is exposed.
