Maintenance operation flow of sandstone
Leveling polishing -- in view of the stone surface is done before waterproof, causing stone discoloration, we did not directly by using the method of leveling grinding, but the first O# steel wire for cotton, grinding, striking ground color layer on the stone surface with special equipment, showing the original bottom gray color. Fortunately, due to the degree of penetration into the surface of the protective agent is very light, we only use the above program has received good results, so that we worry about the problem of governance. Second sets of programs that use marble, sheet, diamond grinding mill grinding and polishing step by step, but not with the preparation.
Fill with filling solution crevice crevice water infiltration is an important preventive measures. Attention must be paid to joint sealing. Filling materials should good adhesion, no powder, waterproof, can be polished, we choose the German super marble crack repair agent, according to the process of filling (fill fill with stone plane back, filling should be uniform, to prevent the omission.) And after more than two hours of curing.
Into the dry - the process is divided into two cases of operation, the original stone surface joints of water stains, we use far infrared lamp heating drying. Other flat moisture, natural drying. As a result, water stains have been completely removed, both economic and reasonable, the customer is very satisfied.
Yellow rust treatment -- according to the overall program, the first serious rust place, grinding with steel wool, remove rust, rust rust agent and special marble. The dust removal process is as follows: clean the surface dry wet paste white paper towel with rust rust agent cover plastic film sealing face aging treatment at 3 hours with neutral cleanser after washing to dry with water (in addition to the net can not one-time rust re processing)
Waterproof, protection -- clients in order to avoid future recurrence of marble water stains, rust and other pan, suffer from pollution, is our scheme applied to protect the ground ground, we learned from the original color protection lessons, with several kinds of waterproof agent good, take the same stone to do the experiment, on the one hand to check the protective effect on the other hand, check whether the change of the stone color, and according to the water absorption process to determine the amount of. Do a good job of preparation, we have a large area of the ground protection. We mainly deal with the following processes: 1. Full drying. Uniform brushing protective agent, run through the stone surface, shall not leak brush, not too much to prevent the accumulation of the former affect the protective effect, which affect the appearance and increase the difficulty of cleaning up. Under natural conditions, ventilation drying for more than 24 hours.
