Coating process: precautions for construction of pure polyurea

It is suggested that pure polyurea is a new type of non solvent, pollution-free, environmental friendly, super long and durable protective material The pure polyurea coating has excellent mechanical properties, outstanding physical and chemical properties such as wear resistance, drainage, water impact resistance, fatigue damage resistance, aging resistance and corrosion resistance Before the construction of pure polyurea, the construction site shall be surveyed in the early stage, including the seepage pressure of the base material, whether there is serious regional seepage, temperature, humidity, etc The construction steps of pure polyurea are summarized as follows: First, substrate treatment Use mortar to level the channel base, especially the parts with settlement and cracks, and maintain for a period of time to make the mortar layer meet the requirements Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Home of coatings news: pure polyurea is a new type of solventless, pollution-free green environmental protection, super long durable protective material The pure polyurea coating has excellent mechanical properties, outstanding physical and chemical properties such as wear resistance, drainage, water impact resistance, fatigue damage resistance, aging resistance and corrosion resistance Before the construction of pure polyurea, the construction site shall be surveyed in the early stage, including the seepage pressure of the base material, whether there is serious regional seepage, temperature, humidity, etc The following summarizes the construction steps of pure polyurea: first, substrate treatment Use mortar to level the channel base, especially the parts with settlement and cracks, and maintain for a period of time to make the mortar layer meet the requirements Then polish and clean the mortar and convex particles on the surface of the leveling layer to ensure that the surface of the base material is clean and dry, and free of such impurities as pockmarks, laitance and oil stain In addition, corners and sharp corners shall be polished to achieve smooth transition Grinding helps to increase the surface roughness of the substrate and improve the adhesion between the coating and the substrate For some water seepage areas, first dry them with blowtorch, then close them with special putty, and finally brush a layer of moisture curing epoxy primer Second, brush the matching primer On the one hand, the adhesion between the coating and the base layer is increased to play a role of connection On the other hand, it can seal the pinhole and microcrack on the surface of substrate The primer shall be applied in a variety of ways to ensure that all substrate surfaces are covered with one coat of primer Third, spray pure polyurea Spray the primer only after the surface is dry Finally, form a 2mm thick anti-seepage coating and check it Repair the unqualified part Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
