Artificial slab maintenance after roughing and refurbishing
Now the floor medallions is to choose the smooth paving of the smooth floor medalions, and then to find the flat refurbished, which is equivalent to repeating the polishing process, and the cost is higher. The correct way is to choose the smooth surface of the stone, then buy the matte specification board, and then paving, leveling, refurbishing and curing. This can greatly reduce costs. This method has long been used in engineering practice in foreign countries, and has not yet formed an application in China. It is mainly due to the disconnection between stone consumers and construction companies, which is inconsistent in concept. The high cost is entirely borne by the consumer.
Although there are many advantages, this method is generally only suitable for granite stones with small color difference and no texture. For many textured marbles, because there is a typographic problem, it should be done by traditional methods. Then proceed with the construction.
Interior floor medalions is not affected by sunlight, wind, acid rain, fog and snow. Therefore, the protective effect lasts for a long time. The impact on the service life of protective chemicals is relatively small. From the perspective of reducing indoor floor medallions decoration decoration pollution and reducing costs, an inexpensive water-based protective agent can be selected. Solvent-based protectants are recommended for use in destructive environments such as waterjet floor medallions.
Rust spots and vomiting yellow should be separated, and it is not easy to use rust remover
Many times, the yellow spots appearing in the stone are mistaken for rust spots. The rust spots contain iron and can be removed with a rust remover. There are two common causes of macular, which are easily confused with rust spots. One is when the wet and paste floor medalions is filled, the organic additive in the cement penetrates into the surface through the capillary pores on the bottom surface, and the double bond of the organic component breaks under the water and oxygen condition, and the color turns yellow. This situation is more common in wet-laid and filled white hemp floor medallions. In another case, in the waterjet floor medallions, the alkali plaque absorbs the surface water to absorb the crystal water to produce a gel layer. After changing the light refraction, the alkali spot color becomes darker, which seems to be "yellower", but actually contains crystal water. The gel layer is at work, so the yellow spots of these genesis cannot be solved simply by using a rust remover. It is necessary to prescribe the right medicine, otherwise it will probably be worse.
