Floor Patching MortarWhat is the role of epoxy flooring in construction?
1. Enhanced the compressive strength and wear resistance of the base. Although the floor patching mortar is not exposed in the middle, it forms a protective barrier above the concrete, thereby improving wear resistance. Floor coatings are essentially a film coating formed through a curing reaction, with limited wear resistance. The role of the intermediate floor patching mortar compensates for this deficiency. From this perspective, we believe it is necessary to incorporate floor patching mortar during the construction process.
2. The intermediate flooring mortar can increase the thickness of the base, thereby enhancing its quality. Both the primer and topcoat have actually very limited wear resistance. If the base is not thick enough, its wear and compressive resistance will significantly decrease. The installation of the intermediate coating can increase the thickness of the floor.
3. Reduce construction material costs. Since the intermediate coating is exposed, it does not affect aesthetics, thereby eliminating the need for color and reducing the addition of dyeing agent materials. From this perspective, the intermediate coating lowers the cost of raw materials usage.
Quartz sand plays a key role in epoxy floor coatings, not only increasing the film volume but also improving the volume shrinkage of the epoxy resin during curing, thereby reducing or eliminating stress cracking caused by volume shrinkage. Due to the high density, low oil absorption rate of barite powder, quartz powder, and other fillers, as well as the reduced linear shrinkage rate of the film, the obtained epoxy floor coatings will exhibit superior film mechanical properties. When calculated by weight, they contain a greater amount of filler in the paint. For instance, in the same paint formula, when the viscosity remains constant, the addition of calcium carbonate is only about 30%, whereas the addition of barite powder and quartz powder can reach over 50%. The fine particle shape of the fillers also has an impact on epoxy floor coatings. For example, spherical particles (such as heavy calcium carbonate) can enhance the coating's fluidity; fibrous particles (such as wollastonite powder) are more effective in reducing the linear shrinkage of the film. During floor installation, various issues may arise on the cement base surface, necessitating adjustments to the repair details based on the actual situation to achieve better strength, hardness, and aesthetics of the repaired cement base surface.
Each process and step in the installation of epoxy flooring serves a specific purpose. After years of verification, a scientific construction method has been developed. For the construction team, it is essential to ensure the quality of each coating application to guarantee the final outcome. High-quality epoxy flooring can be used for a longer duration. Additionally, with proper maintenance, its lifespan can be extended.
