At present, the most common application of quartz stone is cabinet countertops. The biggest headache for everyone should be the discoloration of the splicing seams after using the countertop for about a year.
Among the home decoration stones, quartz stone is listed as a green decorative stone by the country for its characteristics of wear resistance, scratch resistance, high-temperature resistance, anti-permeation, non-toxic, non-radiation, and zero formaldehyde. Quartz stone has the advantages of natural granite, beautiful marble, and artificial stone color. The use of organic resin as a binder makes the appearance of quartz stone warm and round, removing the cold and hard feeling of natural stone, and making the colors more colorful. The application field is more extensive. Quartz stone uses extremely hard quartz sand as the filler so that the hardness of the plate can reach up to 7 Mohs hardness, which also brings certain difficulties to the later processing.
At present, the most common application of quartz stone is the cabinet countertops. The most headache should be the use of the countertops for about a year. The discoloration of the splicing seams directly affects the overall appearance of the cabinets. Quartz stone splicing generally uses glue or marble glue issued by the quartz stone manufacturer. The possible cause of discoloration is the blending of glue or the bleeding of the splicing seams. How to fix it after discoloration, let’s take a look!
Regardless of the discoloration caused by any reason, first, we should insert the discolored gaps and clean the original glue. The next step is to adjust the glue. First, use the same color resin glue from the manufacturer to add quartz powder and stir, and add the curing agent according to the temperature and humidity on-site (too much curing agent will cause yellowing or glue lines). If the embedded gap is too large, you can remove the cushion strip from the underside of the board, polish it and insert it into the gap, and then fill it with the prepared glue. Since the glue will shrink after curing, the solid glue should be higher than the board surface. The last is polishing. After the glue is completely cured, a polishing machine for natural granite can be used to grind from 50-3000 mesh water-grinding sheets from coarse to fine, which will make the board bright and smooth as new. Pay attention to gap protection during use, avoid contact with dark liquids such as soy sauce, vinegar, and other materials. Clean up in time after use, and increase the frequency of gap waxing.
