Question: When the ground stone marble (Yashi White) is polished as a whole, the joints should be opened and repaired first, and then the surface of the stone should be dry-grinded. After the surface loses its gloss, the protective agent is applied. After three days of protection and health, the subsequent sequential grinding and polishing treatments are carried out. After the whole construction process is over, the surface brightness and permeability of the stone are very good, but the color of the area with a finger width at the edge of the stone gap is dark, which affects the visual sense of stone care.
Analysis: It is summer now, the marble glue is thinner, and the glue oil easily penetrates to the edge of the stone. Through analysis and judgment, the color of the stone edge becomes darker, which is mainly caused by the pollution of the joint glue oil.
How to avoid this phenomenon during construction?
First of all, the construction must be carried out according to the specifications. Before opening the seams and mending the seams, the stone must be protected to ensure that the gaps can absorb enough protective agent, and the basic protection treatment for possible pollution should be done. For stone with high water absorption and light color, like Ashe White, after the protective agent is applied as a whole, it needs to be treated again with a brush dipped in the oily protective agent to further enhance the protective effect.
Secondly, the dosage of marble glue curing agent needs to be increased. In summer, the marble glue becomes thinner, and the curing time becomes longer after mending, which increases the possibility of contamination of the stone edge. In this case, it is necessary to increase the dosage of the marble glue curing agent, shorten the curing time of the marble glue curing agent, and prevent the possibility of glue oil pollution.
If the stone has been contaminated by glue oil, how to remove it?
After encountering the above problems, be sure not to rush. If you are rushed to the doctor, use non-professional agents such as carburetor and stain remover in the cleaning industry. This will not only cause unsatisfactory treatment results, but also cause other pollution problems.
The pollution of glue oil is mainly the pollution of glue and oil color. After understanding this truth, we can proceed to deal with it. First use a degreasing paste to brush the contaminated surface. After repeated 1-2 times, if there is a small amount of imprints, then use a decolorizing agent to decolorize. The phenomenon of darkening of the edge of the gap can be basically cleaned.
From the perspective of the processing flow, it is not complicated to remove the pollution of glue and oil color. In this regard, the editor’s friendly reminder: colleagues in stone care, do not think that the process of dealing with glue oil pollution is not complicated, and do not pay attention to standardizing operating standards, otherwise it will definitely affect our corporate professional image.
