Imitate White Marble bridge guardrail 04

The installation and construction method of imitation White Marble railings is very important. The following points should be paid attention to:

1. The White Marble railings must be completely dry when the work is finished, and the moisture content should be less than or equal to the relevant national standards. If there are any broken edges, corners, cracks, voids, etc., they should be repaired first and meet the construction requirements (except for special requirements) before construction can begin& ensp;

 < br />
2. White Marble railings must be dry and clean. Before protective construction, the surface floating ash, glue, wax, cement slag and other pollutants should be cleaned up. If the dirt has penetrated into the interior of White Marble railings, the special cleaning agent for White Marble railings can be used for cleaning. It is not allowed to use non White Marble railing cleaning agent to avoid the situation that White Marble railing has a large area of color reversed to the surface due to improper selection and use of cleaning agent< br />


3. During construction, the non protective surface of White Marble railing shall be properly protected to avoid polluting the non protective surface. Protective measures should also be taken during potential contact tests, such as those that may affect other materials& nbsp;



4. During the construction of permeable protective agent, sufficient amount of protective agent must be allowed to penetrate into White Marble railings. The penetration depth of protective agent into White Marble railings must not be less than 1mm. The construction of closed protective agent must be uniform, and the thickness after waxing must not be less than 0.1mm& ensp;



5. During spray coating construction, it is necessary to ensure that there is relatively less air flow. When using solvent based protective agents, they should be kept away from sources of fire and high temperatures, and protective masks should be worn< br />


6. The temperature of the protective construction environment should be above 5 ℃< br />


7. The coating of protective agent shall be uniform without omission, or it will cause local uneven drying and wetting of White Marble railings after being wet, thus forming new defects. White Marble railings can only be used after protective construction and maintenance. During this period of time, they shall not be exposed to rain and a lot of moisture< br />


8. The White Marble railings after protective construction shall be stacked in single pieces or at inclined intervals. The two White Marble railings shall be separated by hard non pollutant objects, and the air shall be kept well ventilated< br />


9. If any areas are found to have been missed during protective construction, solvent based protective agents should be used promptly for remediation< br />
 
10. One coat of protective agent usually refers to one coat of protective agent on the whole surface to be treated of White Marble railings in two criss cross directions.


11. When the immersion method is used to protect six sides of White Marble railings, the whole White Marble railings cannot be completely immersed in the deeper interior of White Marble railings, thus affecting the protection effect of White Marble railings. The correct method is to soak White Marble railings so that a surface of White Marble railings is always exposed to the outside of the protective liquid, so that the air in White Marble railings can be discharged through a channel. After one side of the White Marble railing is treated, turn over the White Marble railing to soak the other side.
