Destructive thickness gauges and calipers are commonly used for dry film thickness measurement on epoxy floors. When checking, we should pay attention to the representativeness in the selection of measuring points. Because the detection is destructive, it can only be sampled and inspected in places such as edges and corners that do not affect the appearance. The requirements for film thickness of epoxy flooring are as follows: the average value of all measuring points should not be less than 90% of the prescribed dry film thickness; the number of measuring points that fail to reach the prescribed dry film thickness should not exceed 10% of the total number of measuring points. Those who fail to reach the required thickness should be treated as follows: the qualified rate is less than 80%, which needs to be fully repaired; the qualified rate is 80% - 90%, and local repairing should be done according to the situation. Many coatings whose film thickness exceeds the prescribed standard are not generally problematic, but they cause excessive loss of coatings and increase of coating cost. Due to the influence of coating thickness on solvent volatilization and complete drying, as well as curing of the next coating, excessive thickness of coating may also cause wrinkles or cracks, which should be paid attention to. In the construction of epoxy flooring, when the film thickness exceeds 10% of the prescribed maximum dry film thickness, it should be solved.

In the quality control of construction, the standardized management of film thickness is an important one. The management of film thickness is a process of controlling the film thickness in floor paint construction and conducting in-depth analysis, discrimination and quality report and treatment of film thickness after construction. The purpose of film thickness management is to ensure that the thickness of the floor coating not only meets the design requirements to ensure the protective performance, but also avoids waste caused by excessive thickness. Epoxy floor coating has clear requirements for each item M of film thickness management. For example, in the design of coating process, there are strict regulations for the thickness of each thick film and dry film that should meet the standards, and they should be implemented according to the requirements.

Thickness management includes wet film thickness monitoring and dry film thickness monitoring. Wet film thickness in the painting process, in each floor paint painting is now completed for timely inspection. Dry film thickness can be detected in the construction process, but after the completion of construction, the total dry film thickness must be tested.

Wet film thickness measurement is generally used by the coater to guide the builder to determine the required amount of paint to be applied to obtain the expected dry film thickness. There are two kinds of wet film thickness gauge: wet film thickness gauge and wet film thickness comb gauge. The testing methods and techniques of wet film thickness are introduced in relevant books. The advantage of using wet film thickness gauge is that inappropriate film thickness can be checked and corrected during the coating process. If the builder knows the wet film thickness, the dry film thickness can be estimated by multiplying this data by the volume percentage of the solid component of the paint. Or the construction team can also estimate the dry film thickness by the amount of industrial paint used in small area construction, combined with the recommended data of the product description.

In practice, it is difficult to repair after destructive test, so the determination of wet film thickness and the accumulation of each coating thickness and the control of coating dosage (such as the construction of solvent-free self-leveling floor coating) can often be used to replace the total dry film thickness measurement.

The necessity of measuring the thickness of dry film lies in ensuring the thickness of coating up to the standard, avoiding premature failure of coating due to inappropriate thickness, especially for floor coating. Dry film thickness must be measured by dry film thickness gauge after the film is completely dried.
