If using granite water-based protective agent, the dosage must be increased, and the immersion method should be used for protection. And it is necessary to extend the granite curing period. After one day of horizontal maintenance, the scaffold shall be erected for maintenance for two days. If it is erected prematurely, there will be negative and positive faces of granite. Of course, other types of granite protective agents should also be prepared according to the instructions, and a maintenance period of one day should be added to ensure the protection quality.
The bottom protective agent to prevent granite hollowing, whether water-based or oily, is a film-forming type. It must be applied more than two to three times to ensure the integrity of the film layer, reduce bubble holes, and increase waterproof performance. While brushing once only serves as an interface agent and does not increase protection. Many people believe that the film layer looks good to the naked eye, but if you magnify it dozens of times, you will see the micropores formed during drying.
These micropores are completely permeable to water, so applying them twice can reduce the presence of these micropores. Therefore, scientific and careful selection and use of protective agents are the key to ensuring that granite stones do not return to white after paving.
Granite stone renovation and crystal hard care. First of all, the newly paved granite stone should not be renovated and hardened prematurely. This work should be carried out after about a month or even longer. At this time, the hydration reaction of the cement has been completed, the excess water has basically evaporated, and some problems that should occur have also occurred.
At this time, doing granite cleaning, renovation, nursing, and other work will achieve twice the result with half the effort. It can better and more economically complete granite cleaning, renovation, and care work, especially crystal care. "If the water content of granite stone is too high, it is certain that there will be a white bloom phenomenon. It is necessary to polish the granite stone many times until it is basically dry before returning to white bloom. The labor and material costs also have a destructive impact on the granite stone itself.".
This should greatly attract the attention of Party A and the construction unit. In the summer of Beijing, crystal treatment of granite stones before drying is not worth the loss. The granite stone care department should also recognize this, otherwise, granite rework will be inevitable and more than once.
