[construction must read] iron gate paint construction notes
The wrought iron gate is simple and elegant, and it is the choice of many people's home garden gates. The wrought iron gate needs paint construction. So, what are the precautions for construction of wrought iron gate paint? Let's learn together with Xiao Bian! First, the iron door paint requirements 1. The ambient temperature during outdoor painting should be between 5-38°C. If under direct sunlight, the surface temperature of the wrought iron gate can be 8-12°C higher than the air temperature, while in the room without direct sunlight, the wrought iron The surface temperature of the door is only 2-3°C higher than the temperature. 2. The heat resistance of the paint film can only be below 40°C. When it exceeds 43°C, the paint film on the surface of the wrought iron gate product is prone to air bubbles and bulges locally, which reduces the adhesion. When the temperature is lower than 0°C, the paint is easily frozen in the outdoor coating and hardly cured. 3. The best coating time is 3 hours after sunrise. At this time, the dew point attached to the steel surface is basically dry and stops within 3 hours after sunset (indoor work is not limited). At this time, the relative humidity in the air has not yet risen. The remaining surface temperature of the gate product will not cause dew point formation. 4. The relative humidity should not exceed 85%. When it exceeds, dew point condensation occurs on the wrought iron gate surface and the adhesion of the paint film is poor. Within 4 hours after coating, the surface of the paint film has not yet cured and is easily damaged by rain. Therefore, no rain shall be allowed within 4 hours. 5. The finished wrought iron gate surface should not have the appearances of lacquer lacquer, missing coating, peeling, wrinkled skin, mastoid, falling, pinhole, air bubble, back rust, hollow drum, significant sag, loose powder, laitance, etc. Defects, the coating should be uniform. Second, iron gate paint construction 1. Before the door of wrought iron is not installed, clean the dust and stains on it to ensure the effect and quality of the paint construction and avoid cracking and peeling of the paint after painting for a period of time. 2. After the surface with wrought iron gates is cleaned up, it will be well prepared to purchase good paint, and with a brush, the paint will be evenly brushed on the surface of the wrought iron gate. 3. After the painting of the wrought iron gate is completely dry, the installation procedure of the wrought iron gate can be performed. Third, wrought iron gate paint construction considerations 1. Viscosity is appropriate: The paint of the wrought iron gate should be fully stirred and adjusted to the proper viscosity (dilution level) before use. 2, paint can not be mixed use: iron gate paint construction is not the same kind of paint can not mix deployment, and use the same type of thinner. 3, the mixing ratio should be strict: the use of multi-component paint, be sure to be in accordance with the provisions of the use of instructions, mixing must be uniform before use. 4. Paint should be filtered: The surface of the paint is crusted or coarse-grained. Filtering measures should be taken to prevent the paint film from forming unevenly and blocking the spray gun. 5, dry and then re-coating: Each time the coating should not be too thick, and should be completely dry in the case of re-apply the second time to prevent the folder (false dry) wrinkling. Iron gate paint construction is the guarantee of the quality and aesthetics of wrought iron gates. It can effectively prevent the chemical reactions such as oxidation and rusting after the iron in wrought iron gates is in contact with the oxygen in the air or the acid and alkali substances in the air.
