How does the unique construction process of special polyurea wear-resistant and anticorrosion protective coating for foor ensure perfect adhesion to the floor?
Substrate treatment is one of the key steps to ensure coating adhesion.
Cleaning: Use a high-pressure water gun, dust removal equipment or wiping cloth to thoroughly clean the floor surface to remove impurities such as oil, dust, and old coatings. Ensure that the floor surface is dry and clean.
Rust removal and grinding: For metal or concrete surfaces, if there is rust or unevenness, rust removal and grinding are required to make the surface flat and smooth. For concrete surfaces, pickling or sandblasting can be performed if necessary.
Treatment agent coating: Apply a special treatment agent to the treated substrate surface to enhance the surface activity of the substrate and improve the adhesion of the coating. The treatment agent needs to be selected according to the specific substrate, such as metal treatment agent for metal surfaces and concrete treatment agent for concrete surfaces.
2. Primer Construction
Primer is an important link between the substrate and the topcoat to ensure the overall adhesion of the coating.
Evenly mix: Mix the primer with the curing agent, diluent, etc. according to the proportion in the product manual to ensure the correct proportion of the ingredients.
Evenly apply: Use a special roller or spray equipment to evenly apply the primer to ensure that the coating thickness is uniform. The primer should cover all substrate surfaces, especially corners and edges.
Curing time: After the primer is applied, it needs to be cured according to the curing time specified in the product manual, usually within 24 hours, to ensure that the primer is completely cured.
3. Middle coating construction
Middle coating is mainly to enhance the thickness and wear resistance of the coating, and the construction method is similar to that of the primer.
Evenly mix: Mix the middle coating materials evenly according to the proportion in the product manual to ensure the correct proportion of the ingredients.
Evenly apply: Use a special roller or spray equipment to evenly apply the middle coating materials to ensure that the coating thickness is uniform. The middle coating should cover the surface of the primer to ensure that there is no missing coating and uneven thickness.
Curing time: After the midcoat is applied, it needs to be cured according to the curing time specified in the product manual, usually within 24 hours to ensure that the midcoat is completely cured.
4. Topcoat construction
The topcoat is a key coating that provides wear resistance and corrosion protection, and special attention should be paid to details during construction.
Even mixing: Mix the topcoat materials evenly according to the proportions in the product manual to ensure the correct proportion of ingredients.
Even coating: Use a special roller or spraying equipment to evenly apply the topcoat materials to ensure uniform coating thickness. The topcoat should cover the surface of the midcoat to ensure that there is no missing coating and uneven thickness.
Curing time: After the topcoat is applied, it needs to be cured according to the curing time specified in the product manual, usually within 24 hours to ensure that the topcoat is completely cured.
5. Auxiliary construction technology
During the construction process, the following auxiliary technologies should also be paid attention to:
Environmental control: The construction environment needs to be kept clean and dry, and the temperature and humidity need to be controlled within an appropriate range. Avoid construction on rainy days, high temperatures or low temperatures.
Cross-construction: If multiple layers of coating need to be constructed, it is necessary to ensure that each layer of coating is completely cured before the next layer is constructed to avoid the decrease in coating adhesion caused by cross-construction.
Quality inspection: After the construction is completed, the coating thickness, adhesion, hardness and other quality inspections are required to ensure that the coating quality meets the requirements.
6. Post-maintenance
After the construction is completed, regular maintenance is required to ensure the long-term effectiveness of the coating.
Cleaning and maintenance: Clean the coating surface regularly to avoid the accumulation of pollutants such as oil and dust.
Repair and renovation: If local damage to the coating is found, it is necessary to repair it in time to ensure the integrity and protective performance of the coating. If the coating has a long service life, overall renovation can be considered.
In summary, the unique construction process of special polyurea wear-resistant and anticorrosion protective coating for foor ensures that the coating is perfectly attached to the floor through comprehensive control of multiple links such as substrate treatment, primer construction, mid-coat construction, topcoat construction, auxiliary construction technology and post-maintenance, providing excellent wear-resistant and anticorrosion protective performance.
